Work = Force * distance
W = Fd
Given F = 500 N, d = 10 m
W = (500)(10)
W = 5000 J
The work done is 500 Joules. The time of 4 s is irrelevant in this case.
Answer: B) Light
Explanation: light waves are Electromagnetic waves. Visible light is one of the many types of electromagnetic waves. The others are mechanical waves.
The density of the metal is twice the density of liquid since acceleration, a is half of accelerating due to gravity, g.
<h3>What is the relationship between acceleration and density?</h3>
For a solid falling through a viscous fluid, the acceleration of the object decreases until it attains terminal velocity.
The acceleration of the body increases with increase in density of the solid.
When density of solid = density of liquid, acceleration a = g
When density of solid = 2 × density of the liquid, acceleration a = g/2.
Therefore, the density of the metal is twice the density of liquid since acceleration, a is half of accelerating due to gravity, g.

Answer:
L = 3.35 m
Explanation:
given,
mass of the block = 0.2 Kg
spring constant = 1.40 kN/m
until spring compressed = 10 cm
inclination of ramp = 60°
now,
initial potential energy of spring = (work done by friction) + (final gravitational potential energy of block)
L = 3.35 m
