Answer:
(A) Spring constant will be 126.58 N/m
(B) Amplitude will be equal to 0.177 m
Explanation:
We have given mass of the block m = 200 gram = 0.2 kg
Time period T = 0.250 sec
Total energy is given TE = 2 J
(A) For mass spring system time period is equal to 
So 
Now squaring both side
K = 126.58 N/m
So the spring constant of the spring will be 126.58 N/m
(B) Total energy is equal to 
, here K is spring constant and A is amplitude
So 
A = 0.177 m
So the amplitude of the wave will be equal to 0.177 m
The direction of the magnetic field in front of the wire closest to the student is on the left. The direction is found by the right-hand rule.
<h3>What is the right-hand rule?</h3>
The right-hand rule is a popular mnemonic for remembering how axes in three-dimensional space are oriented.
The fact that the three axes of three-dimensional space have two different orientations gives birth to the majority of the many left-hand and right-hand rules.
Using the right-hand rule, we can recall this diagram. Your thumb points in the direction of the magnetic force pushing on the moving charge
If you point your pointer finger in the direction of the positive charge and then your middle finger in the direction of the magnetic field.

That's what happens if there is more than one force acting on the
object, and the forces are balanced, that is, they all "cancel out".
Think of the rope in a Tug-'o-War. It has 50 musclebound football guys
all pulling the rope to the west, and 150 strong cheerleaders all pulling
the rope to the east. The total force to the west is exactly equal to the
total force to the east, and the rope doesn't move at all. The forces on it
are balanced, and the effect on its motion is the same as if there were
no force on it at all.
