Answer:
α = 5 rad / s²
Explanation:
This is a rotational kinematics exercise.
They indicate the initial velocity wo = 10 rad / s
w = w₀ + α t
α =
let's calculate
α =
α = 5 rad / s²
The velocity, the angular relation are the same in all the points of the wheel, the velocities and linear accelerations are the ones that change
a = α r
v = w r
Answer:
3,500,000 J
Explanation:
WORK = POWER * TIME
WORK= 5400 * 640
=6456000 J = 3,500,000 J
The driver speeds up with acceleration <em>a</em> so that
35 m/s = 15 m/s + <em>a</em> (10.0 s)
Solve for <em>a</em> :
20 m/s = <em>a</em> (10.0 s)
<em>a</em> = (20 m/s) / (10.0 s)
<em>a</em> = 2 m/s²
The main advantage of hydroelectric energy is the fact that it is a renewable energy source (Option C).
<h3>What is hydroelectric energy?</h3>
Hydroelectric energy refers to the energy from water bodies that can be used to generate electricity.
Hydroelectric energy is stored as potential energy and then converted to kinetic motion energy to be converted into electricity.
Hydroelectric energy is renewable because it is indefinitely generated by water bodies in nature.
In conclusion, the main advantage of hydroelectric energy is the fact that it is a renewable energy source (Option C).

Answer:When prfessionals take data collections its important becasue it can cause error. Lets say they are sloppy with thier work and end up getting something that is not near what should be happening. This can have a major affect on the truth of what they are doing and an effect on thier end result in general.
