Answer:
25.6 V
Explanation:
The kinetic energy of electron associated with its potential difference is given by eV which is equal to the 1/2 mv^2.
m = 9.1 x 10^-31 kg, v = 3 x 10^6 m/s, e = 1.6 x 10^-19 C
eV = 1/2 m v^2
V = mv^2 / 2 e
V = (9.1 x 10^-31) x (3 x 10^6)^2 / (2 x 1.6 x 10^-19)
V = 25.6 V
44,512,992 mm/m. Hopefully...
Answer:
Explanation:
From the question we are told that:
coefficient of static friction 
Velocity 
Generally the equation for Conservation of energy is mathematically given by
D. It can be seen by the eye. I took this test. Hope this helped!
Answer: in a medium
Explanation:
Mechanical waves require medium to transfer energy. The medium particles vibrate about their fixed position to transfer energy. There is no transport of medium particles.
Example, sound waves are mechanical waves. The sound travels through compression and rarefaction of the medium particles.
