Potential energy I think that’s what your talking about after when it gets hit that potential turns into kinetic
Acceleration = (change in speed) / (time for the change)
Cheetah's change in speed = +21 m/s
Acceleration = (21 m/s) / (6.25 s)
Acceleration = (21 / 6.25) (m / s·s)
Acceleration = 3.36 m/s² (about 0.34 of 1 G)
Answer:
the Corona is about 10 million times less dense than sun's surface.this low density makesuch less bright than surface of the sun
The formular for determinatio of mass number is this:
Mass number = number of proton + number of neutron
From the question, we are told that:
Mass number = 39
Proton number = 19
Number of proton = ?
Number of neutron = mass number - number of proton
Number of neutron= 39 - 19 = 20
Therefore, number of neurtron = 20.
1) By looking at the table of the visible spectrum, we see that blue light has a wavelength in the range [450-490 nm], while red light has wavelength in the range [620-750 nm]. Therefore, red light has longer wavelength than blue light.
2) The frequency f of an electromagnetic wave is related to its wavelength

by the formula

where c is the speed of light. We see that the frequency is inversely proportional to the wavelength, so the shorter the wavelength, the greater the frequency. In this case, blue light has shorter wavelength than red light, so blue light has greater frequency than red light.
3) The energy of the photons of an electromagnetic wave is given by

where h is the Planck constant and f is the frequency. We see that the energy is directly proportional to the frequency, so the greater the frequency, the greater the energy. In this problem, blue light has greater frequency than red light, so blue light has also greater energy than red light.
