A satellite’s original velocity is 10,000 m/s. After 60 seconds it s going 5,000 m/s. What is the acceleration? Remember acceleration = (final speed – initial speed) ÷ time . (p. s i think this is physics? i don't know i just know its science so if anyone can help with this it would be greatly appreciated)

Aman tries to push a box of mass 4 kg with a force of 5 n but the box remains stationary if the coefficient of static friction is 0.45, what is the value of the maximum force of friction?

Akg a of 55 m at an of 11 ? . if is at 98 km/h,be ?

Ultraviolet radiation is dangerous because it has a high enough energy to damage skin cells. what is the best explanation of the relationship between wavelength and wave energy? a) wave energy is related only to frequency, not wavelength. b) longer wavelengths have lower frequencies but higher energy. c) the shorter the wavelength, the lower the frequency and the higher the energy. d) the shorter the wavelength, the higher the frequency and the higher the energy.
