Answer:
The person on Earth will have to exert more force to lift their block
Explanation:
The mass of the blocks to be lifted = 200 kg
The location of the first person = On Earth
The location of the second person = On the Moon
The force a person will have to exert to lift the block = The weight of the block = The gravitational force, F, on the block which is given as follows;
Where;
= The acceleration due to gravity on the Earth or the Moon, depending on the location of the block
m₂ = The mass of the block
Therefore, given that the acceleration due to gravity on the Earth is larger than the acceleration due to gravity on the Moon, the weight of the block on the Earth is larger than the weight of the block on the Moon, and the person on Earth have to exert more force to lift the heavier weight of the block on Earth than the person on the Moon will have to exert to lift the same block as the block has a lower weight on the Moon due to lower acceleration due to gravity on the Moon.
Answer:
a) , b)
, c)
, d)
, e) The direction of the centripetal acceleration experimented by the gum goes to the center of rotation, f) Zero, g)
.
Explanation:
a) The maximum angular velocity of the fan is:
b) The angular acceleration of the fan is:
c) The magnitude of the tangential aceleration is:
d) The magnitude of the centripetal acceleration is:
e) The direction of the centripetal acceleration experimented by the gum goes to the center of rotation.
f) When fan is at full speed, it rotates at constant rate and, hence, there is no angular acceleration. Besides, the tangential acceleration experimented by the gum is zero.
g) The linear speed of the gum is:
