V=λ×f
Answer:
Explanation:
the slits spacing, d = 0.21 mm
distance of screen, D = 61 cm
The condition for minima is given as
So, first minima, n = 0
fifth minima, n = 4
For small angle
From the figure:
Answer: Newtons second law of motion: the acceleration of an object is directly related to the net force and inversely related to its mass. ... So, the force/mass ratio (from the equation acceleration = force/mass) is the same for each. Therefore, the acceleration is the same and they reach the ground at the same time.
Explanation:
Hope this helps you! Have a good day!
Answer:
no. the moon has less of a gravitational pull. therefore it would weigh less than 40n.
