Explain experimental physics. ​

In this case, object b will fly farther than object a.

The distance that an object flies depends on its initial velocity, launch angle, and the gravitational acceleration acting on it. All other things being equal, the object with the higher launch angle will fly farther. In this case, object b will fly farther than object a.

When an object is launched at an angle, it follows a parabolic path under the influence of gravity. The initial velocity of the object, the launch angle, and the gravitational acceleration all play a role in determining the shape and distance of this path.

The launch angle is the angle between the initial velocity of the object and the horizontal. For an object launched at an angle, the vertical component of its initial velocity determines the highest point it reaches, while the horizontal component determines how far it travels horizontally.

For two objects of the same mass, the one launched at a higher angle will have a greater vertical component of its initial velocity, and therefore will reach a higher maximum height. It will also have a smaller horizontal component of its initial velocity, meaning it will take longer to return to the ground. As a result, the object launched at a higher angle will travel a greater horizontal distance before hitting the ground.

Answer:

\(8.0\; \rm J\).

Explanation:

The efficiency of a machine is the ratio between the useful output and the energy input:

\(\begin{aligned}\text{efficiency} &= \frac{\text{useful output}}{\text{energy input}} \times 100\%\end{aligned}\)

Rearrange this equation to find energy input in terms of efficiency and useful output:

\(\displaystyle \text{energy input} = \frac{\text{useful output}}{\text{efficiency} / (100\%)}\).

Substitute in the values: \(\text{useful output} = 1.2\; \rm J\) and \(\text{efficiency} = 15\%\). Evaluate to find the value of \(\text{energy input}\):

\(\begin{aligned} \text{energy input} &= \frac{\text{useful output}}{\text{efficiency} / (100\%)} \\ &= \frac{1.20\; \rm J}{15\% / (100\%)} \\ &= 8.0\; \rm J\end{aligned}\).

(Rounded to two significant figures as in the value of efficiency.)

The angle necessary to keep a 10 kg box motionless, given a coefficient of static friction of 0.55 between the box and the ramp, is 33.4°, which corresponds to Option A.

To determine the angle, we can use the relationship between the coefficient of static friction, the angle of the incline, and the gravitational force acting on the box. The maximum static friction force can be calculated using the formula:

Friction force = coefficient of static friction * Normal force

The Normal force can be found by decomposing the gravitational force acting on the box into components parallel and perpendicular to the incline. The perpendicular component (Normal force) is equal to the weight of the box (mass * gravitational acceleration).

Since the box is motionless, the friction force must be equal to the component of the gravitational force acting parallel to the incline:

Friction force = Component of weight parallel to incline

By substituting the given values and solving for the angle, we find:

coefficient of static friction = tan(angle)

angle = arctan(coefficient of static friction)

angle = arctan(0.55) ≈ 33.4°

Therefore, the correct answer is Option A, 33.4°.

If a person pushed on the door to the left of the handle, they would need to use less force than if they used the handle.

The reason for this is that the handle provides a mechanical advantage over pushing directly on the door. When the handle is used, the force applied to it is multiplied by the mechanical advantage, which is the ratio of the distance through which the handle moves to the distance through which the door moves.

For example, if the handle moves the door a distance of 2 cm and the door moves a distance of 5 cm when pushed directly on it, the mechanical advantage is 2:5, or 0.4. This means that for every 0.4 units of force applied to the handle, the door moves 1 unit.

On the other hand, if the person pushed directly on the door, the force applied to it would be the same as the force applied to the door, without any mechanical advantage. In this case, the door would move 5 cm, not 2 cm, for every unit of force applied to it.

Therefore, the person would need to use more force if they pushed directly on the door than if they used the handle, because they would have to apply the same amount of force over a greater distance to move the door the same distance.

Answer:

A football flying through the air

Explanation:

when an object has projectile motion it is moving through the air

From the given options, the football flying through the air is the prime example of projectile motion. (option d)

Projectile motion refers to the motion of an object that is launched into the air and moves under the influence of gravity alone. It follows a curved path known as a projectile trajectory. Among the options provided, the example that best represents projectile motion is a football flying through the air.

When a football is kicked or thrown, it experiences an initial force that propels it forward. However, as soon as it leaves the kicker's or thrower's hand or foot, the only force acting on it is gravity. Gravity pulls the football downward, causing it to follow a curved path. The shape of the path depends on the angle at which the football is launched and its initial velocity.

During its flight, the football follows a parabolic trajectory, moving both horizontally and vertically. The horizontal component of its motion remains constant, while the vertical component experiences a downward acceleration due to gravity. This combination of horizontal and vertical motion creates the characteristic curved path of projectile motion.

Therefore, option (d) is correct.

Explanation:

As you should be directly south of Tyene, this same angular distance among both yourself as well as the town of Tyene seems to be the distinction to be made throughout the height including its sun at two positions on a specified day.  

The sun is therefore immediately overhead in Tyene, does have an altitude with respect to the horizon will be:  

⇒  \(\Theta_r = 90^{\circ}\)

At the very same day on yourself location, the altitude of the sun will be:

⇒  \(\Theta_A=85^{\circ}\)

Therefore, a complete circle is 360 degrees. So the angular distinction will be somewhere between you as well as Tyene:

⇒  \(\frac{5}{360}\)

Therefore,

⇒  \(\frac{\Theta}{x}=\frac{360}{Circumference}\)

⇒  \(Circumference=\frac{360}{\Theta}\times x\)

If, \(\Theta = 5^{\circ}\)

   \(x (separation) = 600 \ km\)

              = 20 volt

___________________________________________________

4) Total current = 1 A

5) Total voltage = 8 volt

6) Voltage around R₁ is V₁

              R₁ = 2 Ω  ; I = 1 A

              V₁ = IR₁

                   = 1 * 2

                   = 2 volt

7) Resistance 2:

        Total resistance = R

        Total voltage = V = 8 volt

        Total current = I = 1 A

                  \(\sf R = \dfrac{V}{I}\\\\\\ R = \dfrac{8}{1}\\\\\)

                  R = 8 Ω

               R₁ + R₂ = 8 Ω

                2 + R₂ = 8

                      R₂  = 8 - 2

                      R₂ = 6 Ω

8)Voltage around R₂:

                  \(\sf V_2 = IR_2\\\\V_2 = 1*6\\\\\)

                  V₂ = 6 volt

9) Total R = 8 Ω

_________________________________________________

10) Total V = 12 volt

11)  Total R = 8 + 8

                 = 16 Ω

12) Total current I,

                \(\sf I = \dfrac{V}{R}\\\\I = \dfrac{12}{16}\\\\I = 0.75 \ A\)

13) Voltage at each resistor:

           V₁ = I*R₁

               = 0.75 * 8

               = 6 volt

         V₂ = I*R₂

              = 0.75 * 8

             = 6 volt

_______________________________________________________

     14) Total R =   40 + 20

                       = 60 Ω  

15) To find V₁, first find total voltage.

           I = 2 A ;  R = 60 Ω  

           V = IR    

              = 2 * 60

               = 120 V

        V₁ + V₂  =V

        V₁ + 80 = 120

                V₁ = 120 - 80

Work Shown:

density = mass/volume

d = m/v

d = (60 grams)/(3 cubic cm)

d = (60/3) g per cm^3

d = 20 g per cm^3

d = 20 g/cm^3

This means that each cubic centimeter of material has about 20 grams of mass.

A cubic centimeter is a cube that has all sides each 1 cm.

The density of the piece of metal is equal to 20 g/cm³ when the mass is 60 g and a volume of 3 cm³ of metal.

The density of a substance can be measured as the mass per unit volume of that substance. The average density is equal to the total mass of the substance divided by its total volume.

The formula for the density of the substance is represented as follows:

The density of material = Mass/Volume

The density of a material is an intrinsic property as it does not depend on its size and the S.I. unit of the density is Kg/m³. If the size of the substance increases, the mass increases as well but the density of the material remains the same.

Given, the mass of the metal, M = 60 g

The volume of the metal, V = 3cm³

The density of metal = M/V = 60 /3 = 20 g/cm³

Therefore, the density of a piece of metal is 20g/cm³.

If there were no transformation of energy in the world, everything would come to a standstill.

Explanation:

Energy is required for all processes and interactions to occur, including movement and chemical reactions. Without energy, matter would not be able to move or change in any way. This would mean that living organisms would not be able to survive, as they rely on energy to carry out metabolic processes and maintain their body's functions.

The sun would not shine, the wind would not blow and the water would not flow, as they are all driven by energy transformations. The weather would not change, and there would be no seasons. The temperature would not vary and the weather patterns would not change.

Machines and technology would not work, as they also rely on energy to operate. There would be no electricity, transportation, or communication. The economy would come to a standstill as all the industry, trade, and commerce would stop.

In short, without energy transformation, the world would be a static, lifeless place, and life as we know it would not be possible.
