The correct equation for the acceleration is a = (v-u)t. Option D is correct.
<h3 /><h3>What is the first equation of motion?</h3>
The acceleration can be defined as the ratio of change in velocity to time. As given in the question,
The final velocity,
Where,
v - final velocity
u - initial velocity
a - acceleration
t - time
First, bring u with v,
Now bring the t with v-u,
So,
Therefore, the correct equation for the acceleration is a = (v-u)t.

The slope of the distance/time graph is the speed of the moving object.
So the graph for a fast moving object will have a greater slope than the
graph for a slower moving object has.
Answer:
Decrease occur in kinetic energy.
Explanation:
The kinetic energy decreases when the the Bob swings reaches to the maximum height because the motion of the bob slower down. At maximum height, the kinetic energy decreases whereas the value of potential energy is the highest. The main reason of higher potential energy is that it depends on height of an object while on the other hand, kinetic energy depends on the motion of an object so that's why the value of kinetic energy decreases and potential energy increases at maximum height of the bob.
Answer:
reverse bias
Explanation:
bcz the potential barrier and impedes the flow of charge carriers. In contrast, a forward bias weakens the potential barrier, thus allowing current to flow more easily across the junction.
The total energy of the system remains the same.
