According to Newton's third law of motion, "The single ball on the left will move as high as the ball on the right was dropped" is the expected result once the ball hits the ball closest to it.
Answer: Option A
<u>Explanation:</u>
Newton’s cradle is the best example for law of conservation of momentum. So that means that energy or momentum exhibited by a particle can be transferred to its nearer object with equal force. So in the given options the first option is correct. As when the right ball is dropped it will collide with its neighboring ball and transfer energy.
By this transferring of energy from one particle to another, it will reach the leftmost ball. But there will be no loss in the energy as the left ball will move as high position as the ball on the right was dropped from. So that means the energy is conserved in the cradle.
According to Lenz’s law, the induced current itself creates a magnetic field to oppose the change in the external magnetic field.
Using the right hand rule, the clockwise current creates a magnetic field vertically downward.
By Lenz’s law, the created magnetic field points downward in response to...
if the external magnetic field points upward and is increasing in strength...
or points downward and is decreasing in strength.
We are told the external field is increasing in strength, so its direction must be vertically upward.

The photon has a wavelength of
Explanation:
The speed of a wave can be defined as:
(1)
Where v is the speed, is the frequency and is the wavelength.
Equation 1 can be expressed in the following way for the case of an electromagnetic wave:
(2)
Where c is the speed of light.
Therefore, can be isolated from equation 2 to get the wavelength of the photon.
(3)
Hence, the photon has a wavelength of
<em>Summary: </em>
Photons are the particles that constitutes light.
We don't know, and we don't have enough information to calculate it.
The weight of the 60kg load is (m g) = 588 Newtons.
IF Hari wanted to<em> lift </em>the load 12m <em>straight up</em>, he would have to do
(Force x distance) = (588 N) x (12 m) = 7,056 Joules of work.
But to drag it, he has to provide enough force to balance out the force of friction, and we don't know how much that is. It depends on the weight of the load, the shape of the load, the smoothness of the part of the load that sits on the ground, and the smoothness of the ground. But the only thing we know is the weight of the load.
