Value of
Explanation:
We have given
In first case resistance is and current is 1.8 A
Let the potential difference is v
So ----eqn 1
In second case resistance is and current is 1.6 A and potential difference will be as it is a series connection
So ----eqn 2
From eqn 1 and eqn 2
Answer:
The ball experiences the greater momentum change
Explanation:
The momentum change of each object is given by:
where
m is the mass of the object
v is the final velocity
u is the initial velocity
Both objects have same mass m and same initial velocity u. So we have:
- For the ball, the final velocity is
Since it bounces back (so, opposite direction --> negative sign) with same speed (so, the magnitude of the final velocity is still u). So the change in momentum is
- For the clay, the final velocity is
since it sticks to the wall. So, the change in momentum is
So we see that the greater momentum change (in magnitude) is experienced by the ball.
