The initial kinetic energy of the cart is
After the block is dropped into the cart, if there are no other forces acting on it, the kinetic energy of the new system cart+block must be conserved, so it should be the same as before. But the new mass will be M+m, where m=50kg is the mass of the block. Therefore we can write
from which we find
Nutritionist because u don’t need education for it
I think it’s position measured by distance and time.
Answer:
Angle will be
Explanation:
We have given frequency of the sound f = 600 Hz
Vertical opening is of 0.8 meter
So width D = 0.8 m
Velocity of sound v = 340 m/sec
We know that wavelength
Now for the first minimum
