Answer:
smaller force is 20
Explanation:
Let, magnitude of the smaller force be F Newton.
Now, the resultant force makes an angle 90° with the smaller force. So, angle between resultant force and the larger force = (120° - 90°) = 30°.
So, tan 30° = (F * sin 120°) / (40 + F * cos 120°)
(1 / √3) = {F * (√3) / 2} / {40 + F * (- 1 / 2)}
80 - F = 3F
4F = 80
F = 20.
So, magnitude of smaller force is 20 Newtons.
Answer:
Part a)

Part b)

Part c)

Part d)

Explanation:
Part a)
As we know that the during the charging process of the battery the terminal voltage of the cell is given as



Part b)
Thermal energy dissipated in the battery is due to its internal resistance
so it is given as

here we have


Part c)
rate of energy conversion in the in the battery is given as



Part d)
percentage of the power conversion is given as



Explanation:
Once the force of air resistance is as large as the force of gravity, a balance of forces is attained and the skydiver no longer accelerates. The skydiver is said to have reached a terminal velocity.
Answer:
Because the energy is waning
Explanation: hope this helps
Answer:
It appears to rise and set because of the Earth's rotation on its axis. It makes one complete turn every 24 hours. It turns toward the east. As the Earth rotates toward the east, it looks like the sun is moving west.
