Answer: Option B.
Strong nuclear force Gravity.
Explanation:
Nuclear force is the strongest force while Gravity is the weakest force. Strong nuclear force is the strongest force because it's act and hold atoms of matter together. It also binds neutrons and protons together to form atomic nuclei and it's has strength of 1.
Gravity is considered the weak force out of the four fundamental forces because it has a very small strength of 10^40 than electromagnetic force.
Explanation:
Below is an attachment containing the solution.
Answer:
0.15 nm
Explanation:
d = Distance between the atomic planes
m = Order
= First angle = 
= Adjacent angle = 
= Wavelength = 0.07 nm
From Bragg's relation we know
So
The distance between the atomic planes is 0.15 nm.
Neap tides occur at or immediately after the First Quarter
and Third Quarter moon phases. At those times, the moon
is 'to the side' of the Earth. I mean, the sun, Earth, and Moon
make a right angle, with Earth at the vertex.
Answer:
(a) The angular displacement of the toy is 18.85 rad.
----
(b) The toy's angular velocity is 6.284 rad/min.
----
(c) if the counterclockwise rotation is in negative direction, the angular acceleration will be positive when the toy is turned off and vice versa.
