If one bushel is four pecks and one peck is approximately 8.8 liters, then 100 bushels is approximately 3.52 m3, which corresponds to answer choice D.

Let's convert 100 bushels to SI units (m3) using the information given:

1 bushel = 4 pecks
1 peck ≈ 8.8 liters

First, convert bushels to pecks:
100 bushels × 4 pecks/bushel = 400 pecks

Next, convert pecks to liters:
400 pecks × 8.8 liters/peck ≈ 3520 liters

Finally, convert liters to m3 (1 m3 = 1000 liters):
3520 liters × (1 m3 / 1000 liters) = 3.52 m3

So, 100 bushels is approximately 3.52 m3, which corresponds to answer choice D.

According to the given statement the number x is 2. The number x represents the dimensions of the term p * a in the given equation.

By comparing the dimensions of both sides of the equation, we find that x is equal to 2.

The equation given is:

Volume per second = k * (p * a) / n

Where:
- k is a constant
- p is the excess pressure (force per unit area)
- a is the radius of the pipe
- n is the frictional quantity of dimension MLT⁻¹


To find the number x, we need to determine the dimensions of each term in the equation.

1. Dimension of Volume per second:

  - Volume has the dimension L³ (length cubed)
  - Time has the dimension T (time)
  - Therefore, Volume per second has the dimension L³  / T

2. Dimension of k:

  - The equation states that k is a constant. Constants are dimensionless.

3. Dimension of p * a:

  - Pressure has the dimension M / (L * T² ) (mass divided by length and time squared)
  - Radius has the dimension L (length)
  - Multiplying pressure by radius results in the dimension M / (L * T² ) * L = M / (L²  * T² )

4. Dimension of n:

  - Given in the question, n has the dimension MLT⁻¹
(mass times length times time to the power of -1)

Now, we can equate the dimensions:

L³  / T = k * (M / (L²  * T² )) * MLT⁻¹


Simplifying the dimensions:

L³  / T = k * M / (L²  * T² ) * MLT⁻¹


L³  / T = k * M / L²  * M / T²  * L^-1 * T⁻¹


L³  / T = k * M²  / L²  * T⁻¹


To equate the dimensions, both sides of the equation must have the same dimensions. Therefore:

L³ / T = k * M² / L² * T⁻¹


Comparing the dimensions on both sides, we can conclude:

L³ / T = k * M² / L²* T⁻¹

The dimensions on the left side are L^3 / T, and the dimensions on the right side are (k * M²) / (L² * T).

Therefore, the number x is 2.

The number x represents the dimensions of the term p * a in the given equation.

By comparing the dimensions of both sides of the equation, we find that x is equal to 2.

a balanced force acted on it and propelled it to 4,000 km/hr

Explanation:

For the neutrons star which is moving in outer space at 4,000 km/hr, it could only be possible as a result of the balanced force which had already acted on it. This is based on newton's law of motion which states that 'To every action, there is equal and opposite reaction'.

The runner is approximately 8.98 km away from her starting point.

To find the distance of the runner from her starting point, we can use the concept of vector addition and trigonometry.

Let's break down the runner's movement into two components:

Eastward component: The runner initially runs due east for 6 km. Since this is in the eastward direction, the magnitude of this component is 6 km in the positive x-direction.

Northward component: After changing course to E25°N, the runner runs another 9 km. This can be broken down into two components: northward and eastward.

Using trigonometry, we can determine the magnitudes of these components:

The northward component is given by 9 km * sin(25°).

The eastward component is given by 9 km * cos(25°).

Now, let's calculate the magnitudes of the components:

Northward component = 9 km * sin(25°) ≈ 3.80 km

Eastward component = 9 km * cos(25°) ≈ 8.13 km

To find the total displacement from the starting point, we can add the magnitudes of the components using vector addition. This can be visualized as creating a right-angled triangle, with the eastward and northward components as the two sides.

Applying the Pythagorean theorem, the total displacement (d) is given by:

d = √((eastward component)^2 + (northward component)^2)

=\(\sqrt{(8.13 km)^2 + (3.80 km)^2}\))

≈ \(\sqrt{(66.16 km^2 + 14.44 km^2}\))

≈ \(\sqrt{80.6 km^2}\)

≈ 8.98 km

Therefore, the runner is approximately 8.98 km away from her starting point.

               AS WE KNOW THAT

                        W = mG

                         37 = m 9.8

The ratio of kinetic energies of a gas at 200 °C and 100 °C is approximately 1.268 .

It can be determined using the equation:

K.E. = (3/2) * n * R * T

Where:

K.E. = Kinetic energy of the gas

n = Number of moles of the gas

R = Gas constant (8.314 J/(mol·K))

T = Temperature in Kelvin

To calculate the ratio of kinetic energies between 200 °C and 100 °C, we need to convert the temperatures to Kelvin.

200 °C = 200 + 273.15 = 473.15 K

100 °C = 100 + 273.15 = 373.15 K

Now, let's calculate the kinetic energy at each temperature:

K.E.(200 °C) = (3/2) * n * R * 473.15

K.E.(100 °C) = (3/2) * n * R * 373.15

To find the ratio, we divide the kinetic energy at 200 °C by the kinetic energy at 100 °C:

Ratio = K.E.(200 °C) / K.E.(100 °C)

     = [(3/2) * n * R * 473.15] / [(3/2) * n * R * 373.15]

     = 473.15 / 373.15

Space telescopes have the advantage of being above the blurring effects of the Earth's atmosphere.

A surrounding is a layer of fuel or layers of gases that envelop a planet and is held in a region through the gravity of the planetary frame. A planet retains its surroundings whilst the gravity is exceptional and the temperature of the surroundings is low. A stellar ecosystem is the outer area of a celeb, which includes the layers above the opaque photosphere; stars of low temperature may have outer atmospheres containing compound molecules.

The atmosphere of Earth consists of nitrogen (78%), oxygen (21%), argon (0.9%), carbon dioxide (0.04%), and trace gases. most organisms use oxygen for breathing; lightning and bacteria perform nitrogen fixation to provide ammonia that is used to make nucleotides and amino acids; flora, algae, and cyanobacteria use carbon dioxide for photosynthesis.

C. The wave only transfers energy, not matter.

Explanation:

A boat that is bumped by a wave is not actually moved to another position in the water because the wave only transfers energy, not matter.

Basically, waves can only transfer energy over a distance from one point to another without moving matter such as a boat.

This ultimately implies that, a wave can only move an energy but do not move matter.

In science, matter can be defined as anything that has mass and occupies space. Thus, any physical object that is found on earth is typically composed of matter and are generally made up of atoms.

The wavelength of double-slit experiment is 4.97 x 10‾⁷ m

We need to know about double-slit experiments to solve this problem. The double-slit experiment uses monochromatic light and the light which passed through the double slit shows a pattern of light on the screen. The minimum order of the pattern will be

sinθ = (m-1/2) . λ / d

P/L = (m-1/2) . λ / d

where θ is the angle from the light pattern point of the screen to the brightest light pattern, m is the order number, P is the distance between the pattern of minimum light to the center, L is the distance between slit and screen, λ is wavelength and d is the distance between slits.

From the question above, we know that:

d = 0.22 mm = 2.2 x 10‾⁴ m

L = 58 cm = 0.58 m

P = 5.9 mm = 5.9 x 10‾³ m

m = 5

By substituting the following parameter, we get:

P/L = (m-1/2) . λ / d

5.9 x 10‾³ / 0.58 = (5-1/2) . λ / (2.2 x 10‾⁴)

λ = 4.97 x 10‾⁷ m

Hence, the wavelength of double-slit experiment is 4.97 x 10‾⁷ m.

The term for the principal that an object in motion remains in motion until it is met by an outside force is called inertia

Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force .This principal is named as inertia .

Every matter have inertia , a property to remain in that very position until unless it is been forced on them to change their position .

Inertia is a property of matter that causes it to resist changes in velocity (speed and/or direction). According to Newton's first law of motion, an object with a given velocity maintains that velocity unless acted on by an external force. Inertia is the property of matter that makes this law hold true.

It will depend on your frame of reference, assuming no energy is lost in the conversion of energy to motion.

Newton's first law asserts that an object in motion will remain in motion until acted on by a force. The car will remain in motion as long as the forces on it are balanced. However, we currently consider a motion to be moved relative to a frame of reference; depending on your perspective, the car could be traveling forward, backward, or not moving at all.

An external force is described as a change in mechanical energy, which can be either kinetic or potential energy in an item. External agents cause these forces. Friction, normal force, and air resistance are examples of external forces. Because stationery is simply a constant speed of 0. So the pace is constant.

Reference points change based on who is observing because they are subjective and depend on the frame of reference of the observer. A frame of reference is the set of coordinates and axes used to describe the position and motion of objects.

Different observers may have different perspectives, locations, or velocities relative to the observed object, leading to different reference points.

For example, consider two people observing a moving car. If one person is standing still on the sidewalk, their reference point would be the stationary position relative to the car. However, if another person is in a moving car alongside the observed car, their reference point would be the moving car itself.

Therefore, each observer's unique frame of reference affects their perception and measurement of position, velocity, and other physical quantities. Recognizing the relativity of reference points is crucial in understanding how different observers may have different interpretations of the same event or object's motion.

The difference in frequency between the waves that are emitted directly and the waves that are reflected by the paused fish moving straight towards the ship with a speed of 4.95 m/s is 73.45 Hz.

Sound waves will propagate in a straight line until they hit an obstacle, such as the seabed. When the sound waves hit an obstacle, some of the waves will be reflected in the ship as echoes. The time it takes for a sound wave to travel down to the bottom and back up is carefully measured.

The original frequency of sonar, f = 22 kHz = 22000 Hz

The speed of sound in water, V = 1482 m/s

The speed of the whale towards the ship, Vw =4.95m/s

The apparent frequency reflects his back,

f' = f ( V+Vw)/V

f' = 22000(1482+4.95)/1482

f' = 22073.5 Hz.

So, the change in frequency is

f'-f = 22073.5-22000

f'-f = 73.45 Hz.
