Question

a body starting from rest in moving with a uniform acceleration 5 m/s^2 for time 10s and after that with uniform acceleration 10 m/s^2 for time 15s then​

Answer 1

Answer:

To set up a stable and clear interference pattern, two conditions must be met:

The sources of the waves must be coherent, which means they emit identical waves with a constant phase difference.

The waves should be monochromatic - they should be of a single wavelength.

Answer 2

Answer:

The initial velocity travelled is 625m

The accleration is α=10m/s2

The time is t=5s

Apply the equation of motion

v=u+at

The velocity is v=0+10.5=50m/s.

The distance travelled in the first 5s is
