Translucent objects allow some light to travel through them. The light does not pass directly through the materials. It changes direction many times and is scattered as it passes through. Therefore, we cannot see clearly through them and objects on the other side of a translucent object appear fuzzy and unclear.
Answer:
Explanation:
The change in momentum of the ball is equal to the impulse exerted on it, therefore:
where
is the change in momentum
F is the average force exerted on the ball
is the time during which the force is applied
In this problem,
F = 156 N
So, the change in momentum of the ball is
Natural resources like Coal, petroleum etc
Answer:
- The displacement is 33.2 cm in direction to the joint.
Explanation:
The displacement can be obtained as the vector pointing from the starting position to the final position. The nearby joint give us an frame of reference. Putting the starting of the coordinate system at the nearby joint, the vector for the starting position is:
where is the unit vector pointing from this position to the joint. The final position is:
.
So, the displacement vector will be
This is 33.2 cm pointing to the joint.
