The answer is 1 m/s. :::))))
Take the stone's position at ground level to be the origin, and the downward direction to be negative. Then its position in the air at time is given by
Let be the depth of the well. The stone hits the bottom of the well after 5.00 s, so that
Answer: The time of contact will be 0.006 seconds.
Explanation:
An impulse of a force is the product of average force and the time interval when the force acts.
Mathematically,
Where,
J = impulse = 3.6 Ns
F = Force = 600N
= Time = ?s
Putting the values in above equation, we get:
t = 0.006 seconds
Hence, the time of contact will be 0.006 seconds.
Answer:
Slit separation,
Explanation:
It is given that,
Wavelength of light,
The angle between the central bright fringe and the second dark fringe,
In case of double slits, the condition for dark fringe is given by :
n = 2
So, the slit separation is . Hence, this is the required solution.
