Answer:
0.038 m/s, 0.0096 m/s²
0.101
0.103
Explanation:
The speed is given by
v = 2πr / T
v = (2 * π * 0.15) / 25
v = 0.9426 / 25
v = 0.038 m/s
Acceleration, a is given by
a = v² / r =
a = 0.038² / 0.15
a = 0.001444 / 0.15
a = 0.0096 m/s²
Ratio of apparent weight to true weight at the top
w = m (g - a) / (m g)
w = 1 - a/g
w = 1 - 0.0096 / 9.81
w = 0.9904 / 9.81
w = 0.101
Ratio of apparent weight to true weight at bottom
w = m (g+a)/ (m g)
w = 1 + a/g
w = 1 + 0.0096 / 9.81
w = 1.0096 / 9.81
w = 0.103
Answer:
B
Explanation:
momentum = mass (kg) x velocity (m/s²)
I believe it is, since the heat causes the water to evaporate and cause condensation,
Answer:
whats the question?
Explanation:
maybe sphere if its a shape though
Answer:
Increase air resistance
Explanation:
Gravity forces the parachute down but air resistance pushing up on the flat surface of the parachute causes it to fall slower to the ground.
