Answer:
Because the planet is far away from the sun
Explanation:
The closer the planet is to the Sun, the greater the pull of the Sun's gravity, and the faster the planet orbits.
While, over here the Pluto is very far away from the Sun so it will have very little gravitational pull and still keeps revolving around the Sun

Answer:
(a) the runner's kinetic energy at the given instant is 308 J
(b) the kinetic energy increased by a factor of 4.
Explanation:
Given;
mass of the runner, m = 64.1 kg
speed of the runner, u = 3.10 m/s
(a) the kinetic energy of the runner at this instant is calculated as;
(b) when the runner doubles his speed, his final kinetic energy is calculated as;
the change in the kinetic energy is calculated as;
Thus, the kinetic energy increased by a factor of 4.
Answer:
It means that if force is constant, as mass is increased, acceleration decreases
Explanation:
Answer:
Frequency – The frequency of a wave is the number of waves that pass a given point in a certain amount of time. Frequency is measured in units called hertz (Hz), and is defined as the number of waves per second. A wave that occurs every second has a frequency of 1 wave per second (1/s) or 1 Hz.
