If the wagon travels 18.75 m, then the work done on the wagon is
(18.75 m) x (the steady force applied to the wagon all the way, in Newtons) .
The unit is Joules .
Answer:

Explanation:
From the question we are told that:
Frictional force 
Coefficient of kinetic friction 
Generally the equation for Normal for is mathematically given by

Therefore


Answer:c
Explanation:
The buoyancy force on toy depends upon the volume of toy under pool water.
According to Archimedes principle buoyant force on a floating body depends upon the weight of displaced liquid by object.
Buoyancy force is given by

where
=density of fluid
V=volume of object under water
g=acceleration due to gravity
They catch fire with the ohm with the light from the gas with the heat and gas from radiation elects from the chemicals mixed
Answer:
Option (a)
Explanation:
Given that,
Mass of a car, m = 1200 kg
Force exerted by the engine, F = 600 N
Noe force,F = ma
a is the acceleration of the engine

So, the acceleration of the car is 0.5 m/s².
