You throw a ball upward with an initial speed of 3.0 m/s from an initial height of 1.5 m. After you throw the ball, its acceleration is 9.81 m/s2 downward.
Taking upward to be the positive direction, write the position-time equation for the ball's motion.

Answer:

1,600 km

Explanation:

since the acceleration due to gravity reduces by 36%, it means that (1 - 36%) of acceleration still remains:

g' = 64g/100

using the acceleration formula:

g' = g x [R² / (R + height)²]

64g/100 = g x [R² / (R + height)²]

64/100 = R² / (R + height)²

√(64/100) = √[R² / (R + height)²]

8/10 = R / (R + height)

8 (R + height) = 10R

8R + 8height = 10R

8height = 2R

height = 2R / 8 = R / 4

R = 6,400 km

height = 6,400 km / 4 = 1,600 km

Answer:

When weighing chemicals on a balance, the term "tare" is used. Pressing the tare button enables you to record only the weight of the substance being measured, not the weight of the container it is being measured in.

Weighing by difference is automatically accomplished by tarring a balance. When a balance is tared with an object on the balance pan, the weight of the object is automatically subtracted from each reading up until the balance is re-tared or zeroed.

Testing a balance is crucial because you want an accurate result when you weigh an object. The calculations could all be off if a balance is not set to zero.

Explanation:

When light with a 180 nm wavelength is absorbed by the surface, the velocity of the emitted electrons is determined by the kinetic energy and momentum of the emitted electrons.

The photoelectric effect refers to the phenomenon in which the emission of electrons occurs from a metal surface when it is exposed to light. The electrons that are released in this process are referred to as photoelectrons.

According to the photoelectric effect equation, the kinetic energy of the photoelectrons (KE) is determined by the following equation:

KE = hf - Φ  where h is Planck's constant, f is the frequency of the incident light, and Φ is the work function of the metal surface.

According to the photoelectric effect, the kinetic energy of the emitted electrons (KE) is given by the following equation:

KE = 1/2mv² where m is the mass of the electron and v is its velocity.

. The momentum of the emitted electrons is given by the following equation: p = mv where p is the momentum of the emitted electrons. Therefore, the velocity of the emitted electrons is given by the following equation: v = p/m. Thus, the velocity of the emitted electrons is determined by the kinetic energy and momentum of the emitted electrons.

The types of potential energy are:

Potential energy is the energy that an object possesses by virtue of its position or configuration. It is energy that is stored and can be converted into other forms of energy such as kinetic energy (the energy of motion) when the object is set in motion.

The amount of potential energy an object has depends on its position relative to other objects and/or forces acting on it. For example, a ball held at a certain height above the ground has potential energy due to its position relative to the Earth's gravitational field. Similarly, a stretched or compressed spring has potential energy due to its position relative to its relaxed state.

If the reactions were successful then we can see the reactions involved O-H groups of the alcohols then the O-H stretching will not be observed in the product.

Analysis of IR spectrum of 1-butanol:

There are sp3 C-H stretching and CH2 bending modes at 2900 and 1500 cm-1 and there is a C-O stretching mode near 1050 cm-1. There is a very large peak around 3400 cm-1. O-H peaks are usually very broad due to H -bonding.The rounded shape  O-H stretching modes occurs because of hydrogen bonding between different hydroxy groups.

Because protons are shared to varying extent with neighboring oxygens, the covalent O-H bonds in alcohol all vibrate at slightly different frequencies and show up at slightly different positions in the IR spectrum.

Instead of seeing one sharp peak, the entire range is observed as a whole lot of them merged into one broad peak. Since C-H bonds don't hydrogen bond very well, hence this phenomenon is not observed for C-H stretching.

Analysis of IR spectrum of tertiary-butyl alcohol:

There are sp3 C-H stretching and alkane C-H bending modes at 2900 and 1500 cm-1 and there is a strong C-O stretching mode near 1200 cm-1 indicative of tertiary C-O, there is a broad peak around 3400 cm-1 indicative of H bonding.

Some anxiety disorders have different symptoms and it is important to figure out how those symptoms develop. Symptoms may develop from physiological, psychological, or environmental influences. Physiological factors may include heredity, chemical and hormonal imbalances, gender (females are more prone to anxiety than males), and anxiety sensitivity, which has to do with how one’s body reacts to chemical changes. Psychological influences focus on how one’s mind reacts to fearful situations. Environmental factors also influence how individuals deal with fearful situations.  Environmental stress levels, how we think or interpret situations, and our observations of how others react to similar situations all impact how we manage anxiety.

Answer:

The word ‘radiation’ is used to describe particles or waves that are emitted by an object  

In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. This includes: electromagnetic radiation, such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma radiation (γ)

Explanation:

There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how deeply they penetrate people and objects.

The first is an alpha particle. These particles consist of two protons and two neutrons and are the heaviest type of radiation particle. Many of the naturally occurring radioactive materials in the earth, like uranium and thorium, emit alpha particles

The second kind of radiation is a beta particle. It's an electron that is not attached to an atom. It has a small mass and a negative charge. Tritium, which is produced by cosmic radiation in the atmosphere and exists all around us, emits beta radiation. Carbon-14, used in carbon-dating of fossils and other artifacts, also emits beta particles. Carbon-dating simply makes use of the fact that carbon-14 is radioactive. If you measure the beta particles, it tells you how much carbon-14 is left in the fossil, which allows you to calculate how long ago the organism was alive.

The third is a neutron. This is a particle that doesn't have any charge and is present in the nucleus of an atom. Neutrons are commonly seen when uranium atoms split, or fission, in a nuclear reactor. If it wasn't for the neutrons, you wouldn't be able to sustain the nuclear reaction used to generate power.

The last kind of radiation is electromagnetic radiation, like X-rays and gamma rays. They are probably the most familiar type of radiation because they are used widely in medical treatments. These rays are like sunlight, except they have more energy. Unlike the other kinds of radiation, there is no mass or charge. The amount of energy can range from very low, like in dental x-rays, to the very high levels seen in irradiators used to sterilize medical equipment.

When resistors are connected in series, their resistances add up to give the total resistance. So, to find the total resistance for 2905 Ohm, 3292 Ohm, 217 Ohm, and 4074 Ohm connected in series, we simply add their resistances:

R_total = 2905 Ohm + 3292 Ohm + 217 Ohm + 4074 Ohm

R_total = 10688 Ohm

Therefore, the total resistance for the given resistors connected in series is 10688 Ohm.

The range of a cannonball launched with a speed of 35 m/s at an angle of 50 would be 119.1 meters.

The launching of a cannonball is a case of projectile motion.

The formula for the range(R) of a projectile is

R = 2 u² sin(θ) cos(θ)/g

Here,

u = initial speed with which the projectile is launched = 35 m/s

θ = Angle at which projectile is launched = 50°

R = 2 (35)² sin(50) cos(50)/ 9.8

R = 2 x 1225 x 0.76 x 0.64/9.8

R = 119.1 m

The maximum number of 6 AWG THW copper conductors permitted in a 1 1/4-inch RMC conduit nipple, 20 inches long, would be 7 conductors.

To determine the maximum number of 6 AWG THW copper conductors permitted in a 1 1/4-inch RMC (rigid metal conduit) conduit nipple, you need to consider the fill capacity of the conduit as per the National Electrical Code (NEC) guidelines. The fill capacity depends on the size of the conduit and the size of the conductors being used.

According to NEC Table C.9, the maximum fill capacity for a 1 1/4-inch RMC conduit is 0.40 square inches. This measurement represents the total cross-sectional area of the conductors that can be inside the conduit.

For 6 AWG THW copper conductors, you can refer to NEC Table 8, which provides the area per conductor. In this case, a 6 AWG conductor has an area of 0.0507 square inches.

To determine the maximum number of 6 AWG THW copper conductors, you divide the fill capacity of the conduit by the area per conductor. In this case:

Maximum fill capacity of 1 1/4-inch RMC conduit = 0.40 square inches

Area per conductor for 6 AWG THW copper = 0.0507 square inches

Maximum number of conductors = Fill capacity / Area per conductor

Maximum number of conductors = 0.40 / 0.0507

Maximum number of conductors = 7.89

Therefore, the maximum number of 6 AWG THW copper conductors permitted in a 1 1/4-inch RMC conduit nipple, 20 inches long, would be 7 conductors. However, it's important to note that local codes and regulations may impose additional requirements or limitations, so it's always best to consult the relevant electrical codes or a licensed electrician for precise calculations in a specific installation.

Explanation:

Welcome.

The set of arrows describing the magnitudes and directions of the electric force exerted on a proton at positions 1 and 2  is set B depend on the configuration of the electric field in that region.

The electric force exerted on a proton is described by the electric field around it. The electric field is a vector quantity and its direction is the direction in which a positive test charge would move if placed in the field. At position 1, the electric field points towards the right, as indicated by the arrows in both set A and B. However, the electric field at position 2 is pointing towards the left. This is correctly represented by set B, which shows the electric force exerted on the proton at position 2 pointing towards the left.

In an electric field, a proton (positively charged particle) will experience a force in the direction of the electric field. If the field points from left to right, then the force exerted on the proton at position 1 or 2 will also point from left to right. The magnitude of the electric force exerted on the proton depends on the strength of the electric field and the charge of the proton. The force can be calculated using the formula F = qE, where F is the force, q is the charge of the proton, and E is the electric field strength. The magnitudes of the arrows representing the forces at positions 1 and 2 will depend on the strength of the electric field at those positions.

The rate at which the Earth receives energy from the Sun can be estimated using the Solar Constant, which is the amount of energy that is received from the Sun at Earth's distance from the Sun.  

Energy is the ability to do work, or the capacity for action. It is a fundamental property of matter, and can be observed in many forms, such as heat, light, and motion. Energy is found in many different forms, such as electrical energy, chemical energy, nuclear energy, gravitational energy, and kinetic energy. It is also the capacity to produce changes in the physical world. Energy can be converted from one form to another, and can be used to power machines, heat and light homes, and even provide electricity for our electronics.

The Solar Constant is typically measured in Watts per square meter (W/m^2). The approximate value of the Solar Constant is 1,370 W/m^2. To estimate the rate at which the Earth receives energy from the Sun, we can multiply this value by the total surface area of the Earth.

To estimate the average surface temperature of the Earth, we can use the Stefan-Boltzmann Law. This law states that the total energy radiated by a perfect emitter (ε = 1.0) is proportional to the fourth power of its absolute temperature.
