From the statement, the wavelength should be 1.6 cm * 1/4 = 0.4 cm. Then, we use the wave equation formula. The frequency is equal to the speed of light divided by the wavelength. First, let's use the SI units.
0.4 cm = 0.004 m
The speed of light is equal to 3 x 10^8 m/s
Frequency = 3 x 10^8 m/s ÷ 0.004 m
Frequency = 7.49 x 10^10 s^-1
He would manage to stop very close but je would stop and not impact
Temperature has a direct effect on the pressure of a gas.
If the pressure is constant and the gas is free to fill more
or less space, then temperature also has a direct effect on
the volume of the gas.
Answer:
25.2563 m/s
Explanation
This is the equation needed
So Just plug in!
Think about the formula for potential energy. (Surely you remember it):
Potential energy = (mass) x (acceleration of gravity) x (height)
-- The mass on the end of the pendulum doesn't change.
-- The acceleration of gravity doesn't change.
-- The only thing that changes is the height of the mass on the end.
So the potential energy is lowest when its height is the lowest.
That's position <em>B </em>.
