Answer:
Explanation:
spring constant, K = 13.1 N/m
22 oscillations in 20 seconds
time taken to complete one oscillation is called time period.
T = 20 / 22 second = 0.909 seconds
(a) let m be the mass.
The formula for the time period is
m = 0.275 kg
(b) maximum speed, v = ω A = 2π A / T
v = ( 2 x 31.4 x 0.1) / 0.909
v = 0.691 m/s
Answer:
B
Explanation:
because it has more power
4.0 cm
Hope this helps (:
Answer: c. they will hit the ground at the same time
Explanation:
The volume of both objects is almost the same, so the force of friction will be the same in each one, so we can discard it.
Now, when yo drop an object, the acceleration of the object is always g = 9.8m/s^2 downwards, independent of the mass of the object.
So if you drop two objects with the same volume but different mass, because the acceleration is the same for both of them, they will hit the ground at the same time, this means that the density of the object has no impact in how much time the object needs to reach the floor.
So the correct option is c
