False.
The mass of a softball is approximately 200 g (0.2 kg), while the knees are located approximately at 30 cm (0.3 m) from the ground. It means that the gravitational potential energy of the ball when it is dropped is
This corresponds to the total mechanical energy of the ball at the moment it is dropped, because there is no kinetic energy (the ball starts from rest). Then the ball is dropped, and just before it hits the ground, all this energy is converted into kinetic energy: but energy cannot be created, so its final kinetic energy cannot be greater than 0.6 J.
Answer:
4.78 x 10^-17 m
Explanation:
E = 26 GeV
First convert GeV into J
1 GeV = 1.6 x 10^-10 J
E = 26 x 1.6 x 10^-10 = 41.6 x 10^-10 J
Use the formula for energy
E = h c / λ
Where, h is the Plank's constant and λ be the wavelength and c be the velocity of light.
λ = h c / E
λ = ( 6.63 x 10^-34 x 3 x 10^8) / (41.6 x 10^-10)
λ = 4.78 x 10^-17 m
Answer:
Fundamental frequency is 200 Hz.
Explanation:
It is given that,
Frequency of the 3rd harmonic is 600 Hz.
Let f is the fundamental frequency. We need to find the value of f. The frequency of third harmonic is given by :
So, fundamental frequency f is equal to :
f = 200 Hz
So, the fundamental frequency of the harmonics is 200 Hz. Hence, this is the required solution.
We have that the magnification of each focal length is given respectively as
