Every mass is attracted to every other mass with a force that is proportional
to the product of both masses and inversely proportional to the square of the
distance between their centers of mass. The forces act along the line between
their centers of mass.
Correct option B
Transverse waves are those waves whose particles vibrate perpendicular to the direction of wave.

Sudden movements in the fault line, ex: San Andreas fault line, can cause sudden earthquakes,
is the equation that represents the Joule's law of heating.
<h3>
Explanation:</h3>
Joule's law of heating defines the heat generated by any current flowing conductor is directly proportional to
1. Square of Current (I²),
2. Resistance of the conductor (R)
3. Time for which current is passed (t)
Hence, Heat generated = 
.....................(1)
By Ohm's Law, the potential difference (V) across a conductor is directly proportional to the current(I) flowing through it. The constant of proportionality is termed as resistance of the conductor (R).
...............................................(2)
From (2), Current (I) can be rewritten as
........................................................(3)
Substituting (3) in (1), we get
Answer:
D) multiply the force in the direction of motion by the distance the object moved
Explanation:
To calculate work done on an object, multiply the force in the direction of motion by the distance the object moved.
