Answer:
a = w² r
Explanation:
In this exercise, indicate that the wheel has angular velocity w, the worm experiences the same angular velocity if it does not move, and has an acceleration towards the center of the circle, according to Newton's second law, called the centripetal acceleration.
a = v² / r
angular and linear variables are related
v = w r
we substitute
a = w² r
where r is the radius of the wheel
Answer:
Explanation:
Given
mas of block
speed of block
spring constant
As the mass collides with the spring its kinetic energy is converted to the Elastic Potential energy of the spring
F = m*a => a = F/m = 50N / 100 kg = 0.5 m/s^2
Vf^2 = vo^2 + 2gd
Vf^2 = 0 + 2*9.8m/s^2 *5.5m =107.8 m^2 / s^2
Vf = 10.4 m/s
Answer:
Absorption, in wave motion, the transfer of the energy of a wave to matter as the wave passes through it. The energy of an acoustic, electromagnetic, or other wave is proportional to the square of its amplitude—i.e., the maximum displacement or movement of a point on the wave; and, as the wave passes through a substance, its amplitude steadily decreases.

Directions
Genes provide <u>directions</u> for a cell to assemble molecules that express traits such as eye color of seed shape.
<h3><u>Explanation;</u></h3>
- <em><u>A gene is a segment of DNA on a chromosome that codes for a specific trait. It is the set of information that controls a given trait.</u></em>
- Each gene occupies a specific position on a chromosome. Genes are responsible for characteristics inherited by an individual from the parents,because genes provide instructions for making proteins, and proteins determine the structure and function of each cell in the body.
