P = MxV
P1 = 500 x 2.5 = 1250
P2 = 3 x ? = 1250
P2 = 1250/3 = 416.66 m/s
<h2>MARK BRAINLIEST</h2>
For this assignment, you will develop several models that show how light waves and mechanical waves are reflected, absorbed, or transmitted through various materials. For each model, you will write a brief description of the interaction between the wave and the material. You will also compose two <u><em>typewritten</em></u> paragraphs. The first will compare and contrast light waves interacting with different materials. The second will explain why materials with certain properties are well suited for particular functions.
<h2><u>Background Information</u></h2>
A wave is any disturbance that carries energy from one place to another. There are two different types of waves: mechanical and electromagnetic. A mechanical wave carries energy through matter. Energy is transferred through vibrating particles of matter. Examples of mechanical waves include ocean waves, sound waves, and seismic waves. Like a mechanical wave, an electromagnetic wave can also carry energy through matter. However, unlike a mechanical wave, an electromagnetic wave does not need particles of matter to carry energy. Examples of electromagnetic waves include microwaves, visible light, X-rays, and radiation from the Sun.
The change in momentum, Δp, of the body is 23520 Kgm/s
<h3>Momentum </h3>
- The momentum of a body is defined as the product of its mass and velocity
Momentum, p = m×v
<h3>Change in momentum </h3>
Change in momentum is equal to the final momentum minus the intiala momentum
Change in momentum = mv - mu
Mass of car = weight/g
where g = 10 m/s^2
Mass of car = 15680/10
Mass of car = 1568 Kg
Change in momentum = 1568 Kg × 20 - 1568 Kg × 5
Change in momentum, Δp = 23520 Kgm/s
Therefore, the change in momentum, Δp, of the body is 23520 Kgm/s

Gravity
Explanation:
Johanna's table:
Circular motion Centripetal force
space station in orbit X
a child in a swing
a ball on a string
The type of centripetal force at work in a space station in orbit is the force of gravity.
The force of gravity is constantly pulling and attractive all objects and bodies to its center.
This force is directed towards the center of the orbit of the earth and it is a centripetal force
- Gravity attracts any object that has mass.
- The mass of the satellite and the earth keeps it in orbit and prevents it from moving out of orbit.
- The more the mass the more the gravitational attraction.

Displacement of a body is always in a straight line in the direction of the final position regardless of the path taken to reach the final position.
Therefore, the displacement of the car can be obtained by joining the car's initial position to the final position and then counting the number of squares covered by the line. Then we multiply the number of squares by the scale and note the direction of the final position from the initial.
that is: 4×1km= 4km North since displacement is a vector.
