Calculate the time it takes for the car to reach the beginning of the hill given that acceleration as already found in part a is 2.89 m/s²
Answer:
5.88 s
Explanation:
Using kinematic equation, v=u+at where v and u are the final and initial velocities respectively, a is acceleration and t is time.
Considering the first part, acceleration is already found as 2.89 m/s and the final velocity is given as 17 m/s while the initial velocity is zero since it is at rest.
Making t the subject of formula then
t=(v-u)/a
Substituting the given figures then
t=(17-0)/2.89=5.8823529411764s
Rounded off, t=5.88 s
Electric field strength decreases as the distance from the source increases.
<h3>
How the distance from the charge affects the magnitude of the electric field?</h3>
The strength of an electric field is inversely related to square of the distance from the source. This means that the electric field strength decreases when the distance from the source increases.
So we can conclude that Electric field strength decreases as the distance from the source increases.
