A 0.025 kg piece of clay is thrown into a wall and has a speed of 9 m/s before it strikes the wall. Find the
change in momentum, of the clay and the impulse exerted on the clay if it does not bounce from the wall.
Answer:
The impulse experienced by the object equals the change in momentum of the object. In equation form, F • t = m • Δ v. In a collision, objects experience an impulse; the impulse causes and is equal to the change in momentum.
Explanation:
When A 0.025 kg piece of clay is thrown into a wall and has a speed of 9 m/s before it strikes the wall then change in momentum 22.5 kg.m/s² is and impulse is 0.225 Ns.
What is Momentum ?Momentum is defined as product of mass and velocity of the body. It is denoted by letter p and it is expressed in kg.m/s.
Mathematically p = mv.
it discuss the moment of the body. body having zero mass or velocity has zero momentum.
The dimensions of the momentum is [M¹ L¹ T⁻¹].
Given,
mass of the clay = 0.025 Kg
Speed of the clay = 9m/s
The momentum of clay is P = mv = 0.025×9 =0.225 kg.m/s
In this problem a piece of clay having mass 0.025 Kg, velocity of clay is 9m/s.
By using formula,
change in momentum of the clay = dp/dt
We must know about change in time in order to calculate change in momentum with respect to time.
Consider that the change in momentum is 0.01s.
dp/dt = p₂-p₁/t₂-t₁ = 0- 0.225/0.01 = 22.5 kg.m/s²
Impulse = dp/dt×Δt = 22.5×0.01 = 0.225 Ns

The human pupil, when maximally dilated, has a diameter of roughly 10 mm. How much more light does the primary mirror of the Magellan telescope (measuring 6 m in diameter) collect compared to the human eye
The amount of light collected by Magellan telescope with respect to human eyes is 1.13 x 10⁶ times that of human pupil.
Amount of light collect by human pupilThe amount of light that will pass through the given area of human pupil when maximally dilated is calculated as follows;
A = πd²/4
A = π(0.01)²/4
A = 2.5 x 10⁻⁵π m²
Amount of light collect by Magellan telescopeA = πd²/4
A = π(6)²/4
A = 9π m²
with respect to human eyes = ( 9π m²)/(2.5 x 10⁻⁵π m²)
= 1.13 x 10⁶ x human pupil

Answer:
Diagram B because a plate resting on a table has gravity acting on it and normal/air resistance force working against the gravity with the same amount of force. Forces that are balanced don't move.
Explanation:
I hope this helps
Diagram B represents the forces acting on the plate that is at rest on the kitchen table.
What is normal force?Every day, we experience the normal force.
In this instance, when we lay a plate on a kitchen table, the normal response force prevents the plate from going through the table, even if gravity is pulling the plate downward. That implies that there is a force acting to push it upward. The word "normal force" refers to the force. Normal in this context refers to being perpendicular to the ground.
Hence, in diagram B, downwards arrow represents gravitational force acting on the plate for its weight and upwards arrow represents normal force acting on the plate by the table.

An electromagnetic am-band radio wave could have a wavelength of.
An electromagnetic AM-band radio wave could have a wavelength of 186.6 meters.
Wavelength is the distance between two consecutive points on a wave that are in phase, meaning they are at the same position in their respective cycles. It is usually denoted by the Greek letter lambda (λ) and is measured in units of length, such as meters, centimeters, or nanometers.
The relationship between wavelength, frequency, and speed of a wave is given by the formula:
wavelength = speed / frequency
where "speed" refers to the speed of the wave through a medium, and "frequency" refers to the number of cycles per second.
The AM radio band frequency ranges from 535 kHz to 1605 kHz. To find the wavelength of the AM radio wave, we can use the formula:
wavelength = speed of light / frequency
where the speed of light is approximately 299,792,458 meters per second.
Let's take the highest frequency in the AM radio band, which is 1605 kHz. We need to convert this frequency to Hertz (Hz) by multiplying it by 1000 since kHz is 10^3 times larger than Hz.
1605 kHz = 1605 x 1000 Hz = 1,605,000 Hz
Now, we can calculate the wavelength of the AM radio wave using the formula:
wavelength = 299,792,458 / 1,605,000
wavelength ≈ 186.6 meters
Therefore, an electromagnetic AM-band radio wave could have a wavelength of approximately 186.6 meters.
