no.9 indeed all matters are made out of atoms which is smaller than protons and neutrons
Answer:
1.44*10^-3m
Explanation:
Given that distance BTW two bright fringes is
DetaY = lambda* L/d
So for second wavelength
Deta Y2= Lambda 2* L/d
=lambda 2 x deta y1/ lambda1
So substituting
= 360 x 10^-9 x (1.6*10^-3/640*10^-9)
1.44*10^ -3m
Answer:
when all forces acting on an object remain the same
Answer:
6.96 s
Explanation:
The period of a simple pendulum is given by:
where
L is the length of the pendulum and g the acceleration due to gravity.
In this problem, we have a pendulum with length L = 2.00 m, while the acceleration due to gravity is 1/6 that of the earth:
So, the period of the pendulum on the moon is
