Answer:
7.67001846 km/s or 17157.38529 mph
Explanation:
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
M = Mass of the Earth = 5.972 × 10²⁴ kg
m = Mass of satellite
v = Velocity of satellite
The distance between the Earth's center and the satellite is
r = 6371000+400000 = 6771000 m
As the centripetal force balances the force of gravity we have
Converting to mph
The velocity of the satellite is 7.67001846 km/s or 17157.38529 mph
Answer:
F = mg= 20x9.8 N
Explanation:
Aplicar la segunda ley de Newton
First we start from the definition of synchronization itself. This is known as the rate of change in the occurrence of an event to occur at the same time. If the light clocks of a train are verified it will be possible to observe that there are different verification times between each of them different. This is because the light of the clocks at each end of the train does not appear instantaneously over them, but travels from one direction to another; the light at the rear must have traveled a distance that will cause the first clock to have changed position.
In this way, if a clock of these is observed at the same time, the light will generate that the first one is out of sync with the last one, which would cause the clocks not to be synchronized.

Answer:
53 V
Explanation:
Since the problem gives you a Resistance and a Current, you can use Ohm's Law (V = IR) to solve the problem.
Ohm's Law is Voltage = Current * Resistance
For this problem, the current is 0.54 A (amperes) and the resistance is 98 ohms. Plugging this into Ohm's Law gives:
V = (0.54 A)(98 ohms) = 53 V
