Answer:
Options A and B.
Explanation:
Gravitational acceleration, initial height, intial speed and time are required to determine final speed. The option D is incorrect, since speed varies in time. Option C is dimentionally wrong.
The correct strategy is calculating the initial height from option B. Later, substituting time in equation A to derive an expression of the final velocity in terms of position. Hence, the required equations are options A and B.
Answer:
Explanation:
Distance between the satellite and Earth =
Speed of light =
Propagation delay is given by distance by the speed of light
The uplink propagation delay of the link is .
Explanation:
Wave speed = (frequency) x (wavelength)
= (266 /sec) x (1.3 meters)
Answer: The unit of impulse is applied to an object produces an equivalent vector change in its linear momentum, also in the same direction.
