Answer:
0.495 m/s
Explanation:
= tension force in the string connecting the two objects
= Mass of the object on inclined plane = 250 g = 0.250 kg
= Mass of the hanging object = 150 g = 0.150 kg
= acceleration of each object
From the force diagram, force equation for the motion of the object on the inclined plane is given as
From the force diagram, force equation for the motion of the hanging object on the inclined plane is given as
Using the above two equations
= height dropped by the hanging object = 10 cm = 0.10 m
= Speed gained by the object
Speed gained by the object can be given as
The speed of light is approximately 3.00 x 10^8 m/s. Then the next step is to convert m/s into km/s.To determine the time, the distance must be divided with velocity. It will take the light signal 3.3*10^-6 seconds to reach his assistant.
Answer:
Astronauts who are orbiting the Earth often experience sensations of weightlessness. These sensations experienced by orbiting astronauts are the same sensations experienced by anyone who has been temporarily suspended above the seat on an amusement park ride. Not only are the sensations the same (for astronauts and roller coaster riders), but the causes of those sensations of weightlessness are also the same. Unfortunately however, many people have difficulty understanding the causes of weightlessness.
