Explanation:
It is given that,
Relativistic Mass of the stone, m₀ = 0.6
Mass,
Relativistic mass is given by :
.........(1)
Where
c is the speed of light
On rearranging equation (1) we get :
v = 0.61378 c
or
v = 0.6138 c
So, the correct option is (c). Hence, this is the required solution.
Answer:
150N
Explanation:
formula= pressure= force/area
300pa= x/0.5
300*0.5= x
150N= x
force= 150N
the answer is C the wave is moving horizontally as the particles of the rope move up and down.
Answer:
4.(615384)Hz
Explanation:
Firstly, let's take a note that the speed of light is much higher than 30m/s, on the other hand visible light has wavelengths measured in nanometers, so I assume we're just supposed to assume the values in the question for the purpose of solving it.
If a wave moves through a point with speed v and has wavelength l, In each second we observe v/l cycles - and cycles per second is the frequency!
F = 30m/s / 6.5m = 4.(615384)/s = 4.(615384)Hz
