Answer:
<em>The person needs to apply 25 N to balance the seesaw</em>
Explanation:
<u>Moment</u>
The moment of a force is a measure of its tendency to cause a body to rotate about a specific point or axis.
The moment M of a force F located at a distance x from the axis of rotation is calculated as follows:
M = F.x
The image shows a moment of M=100 N.m is needed to be applied to balance the seesaw. It can also be noted that the distance to the pivot is x=4 m
To calculate the force needed to balance the seesaw, we solve for F:
F = 25 N
The person needs to apply 25 N to balance the seesaw
"b. The nucleus is made of
protons and neutrons and has a positive charge" is the only option that is true about the atomic nucleus. The protons give it a positive charge.
Momentum before the hit:
p = mv = 0.01 * 300 + 1 * 0
Momentum after the hit:
p = 0.01 * 150 + 1 * v
Momentum is conserved:
0.01 * 300 = 0.01 * 150 + v
3 = 1.5 + v
v = 1.5
The velocity of the block after the collision is 1.5 m/s.
