Speed of any freely falling object is always same. Provided, both are left to fall from the same height. If you perform this experiment in a perfect vacuum or near vacuum laboratory, both of them will reach ground with same velocity this is because there is no resistance to their motion. This is always true no matter where you go and perform this experiment.
It can be easily proved from conservation of mechanical energy. Why conserving energy? because there are no forces acting on the freely falling objects other than conservative force(mg).
B.riding on a ferris wheel
E.a satellite orbiting the Earth
Explanation:
A person riding on a ferris wheel and a satellite orbiting the earth both depicts circular motion.
Circular motion is the motion of a body about a fixed axis or center.
- The motion path of the body forms a circle around the center.
- In circular motion, the travel path is along a circle.
- An orbiting satellite traces out its orbit round the earth.
- At certain times, it passes through that point over and over again.
- This is similar to that of a ferris wheel
Other options gives other types of motion.

Answer:
c. Velocity
Explanation:
Velocity is a measure of change of position of the body with time. Change of position means the distance traveled by the object in a given interval of time but in a particular direction.
We know that speed is given as the distance traveled over a given time interval without taking into account the direction of motion. So, the magnitude of velocity is same as its speed. Velocity, being a vector quantity, has both magnitude and direction.
Therefore, the <u>velocity</u> of an object consists of its speed and direction.
Answer: 8.242 × 10 exp -8 N
Explanation: F = G *m* M/r^2
r = √(13-5)^² + (51-15)^² + (0-0)²
r = 8; the distance between the masses
G =6.673 × 10 -¹¹ Nm²kg-²
F = gravitational force of attraction of m(51kg) on M {1550kg)
