Answer:
1.28second
Explanation:
The speed of light is constant everywhere, it is
299,792,458m/s=299,792.458km/s
Therefore it takes
C it takes a lot of capital to get the windmills and the fields of windmills set up
Answer:
The speed of the roller coaster at this point is 18.74 m/s.
Explanation:
Given that,
Weight of the student, W = 655 kg
Weight of the roller coaster,
Radius of the roller coaster, r = 18 m
At the bottom of the loop, the weight of the roller coaster us given by :
If m is the mass of the roller coaster,
m = 66.83 kg
So,
v = 18.74 m/s
So, the speed of the roller coaster at this point is 18.74 m/s. Hence, this is the required solution.
Answer:
False
Explanation:
The roller displacement at an external, friction less rotation pin is found to be zero as it has a support which is no-yielding but still provides rotation to the object where as at an external pin a shear force is present and the moment is absent which means that at an external pin its not the rotation that is absent but its the moment which comes out to be zero.
