Answer:
True; ar = v^2 / R Radial acceleration because it moves in a circular path
at = α R = tangential acceleration because its speed changes
a = at + ar total acceleration equals sum of radial and tangential
Answer:
solar wind
Explanation:
the sun's atmosphere is made of hydrogen which itself made subatomic particle. These particle are constantly boiling off the sun and streaming outward at very speed. So, the sun's magnetic field and particles are called solar wind.
Answer:
A 50 kg ball traveling at 20 m/s would have 4 times more kinetic energy.
A 50 kg ball traveling at 5 m/s would have 4 times less kinetic energy.
A 50 kg person falling at 10 m/s would have the same kinetic energy.
Explanation:
hope this helps:)
Answer:
The object is not at a constant speed. It is either gaining speed or losing speed.
Explanation:
A speed-time graph measures how fast you are going in a certain amount of time.
Answer:Explained Below
Explanation:
Radiation in everyday language refers to certain type of subatomic particle released by a radioactive unstable nucleus.It can be used to kill the cancer by damaging the DNA of cancer cells.
The transmission of energy in the form of waves via a material medium is called radiation in astronomical context.
