Answer:
But once the core runs out of hydrogen, the star starts to contract again briefly, until a shell of hydrogen around the core becomes hot enough to fuse into helium. When this happens, the radiation pushes the outer layers of the star far out into space, turning the star into a red giant
Explanation:
Correct?
B. Friction forces I am still typing bc it says my answer needs to be 20 characters long :)
The mass of the car at the given kinetic energy is 920 kg.
The given parameters;
- initial velocity of the car, u = 22 m/s
- kinetic energy of the car, K.E = 222,640 J
Kinetic energy if the energy acquired by a body during its motion. This kinetic energy is the product of average velocity squared and mass of the object.
The mass of the car at the given kinetic energy is calculated as follows;
Thus, the mass of the car at the given kinetic energy is 920 kg.
