Answer:
W = 0.49 N
τ = 0.4851 Nm
Force
Explanation:
The weight force can be found as:
W = mg
W = (0.05 kg)(9.8 m/s²)
<u>W = 0.49 N</u>
The torque about the pivot can be found as:
τ = W*d
where,
τ = torque
d = distance between weight and pivot = 99 cm = 0.99 m
Therefore,
τ = (0.49 N)(0.99 m)
<u>τ = 0.4851 Nm</u>
The pivot exerts a <u>FORCE </u>on the meter stick because the pivot applies force normally over the stick and has a zero distance from stick.

Answer:
275 kJ
Explanation:
KE = ½mv² = ½(1200)(25²) = 375,000
We have heat lost by water is equal to heat gained by Juice.
Heat exchanged is calculated using the formula,
Let be the final temperature then,
The final temperature of the juice is 12.913 K.
If two charges are moved so that the distance between them is reduced
by half, then the forces between them become 4 times as strong.
