Answer:
The correct answer is c. There is no component of force acting along the direction of motion of the satellite.
Explanation:
When a moving object is traveling in a circular orbit at a constant speed we assume it has a changing velocity, this is mainly because velocity is a vector quantity that rely on the speed the object is moving and direction, because of the variation of acceleration throughout the whole orbit and the lack of other force acting along the direction of motion of the satellite allows the object to travel at a constant speed, but variable acceleration.
At one point, the value of the United States dollar was set according to the gold standard. One of these examples is the fixed exchange rate. The gold exchange standard guarantees the fixed exchange rate to the currency of another country that uses the gold standard.

These theories were constructed, or created by humans, which makes them human constructions. They didn't exist before humans made them - they weren't previously part of nature around us. Rather we created them to suit our own needs and to make us understand life in general.
Answer:
Speed of sound wave v=νλ=2000×0.35=700 m/s
Distance d=1.5 km=1500 m
Time t=vd=7001500≈2 s
