Yes, an abject in motion stay in motion.
Work is equal to the force applied to an object multiplied by the distance it had travelled. This is work as long as the force and the direction of the distance in going in the same direction.
It is work because you're applying a force on an object to move it.
For example, work is done when you push a box across the floor, but work is not done when you lift the box up and then walk it across the room. This is because the force on the box is upwards since you're lifting it and the direction of the distance is left or right so the directions are not the same.
Answer:
high frequent sound
Explanation:
because if its low than its slower.
Answer:
80N/cm^2
Explanation:
Given data
A car of weight 6,400N
Area= 80cm^2
The weight is distributed evenly on the 4 wheels
hence 6400/4
=1600
N
We know that
Pressure = force/Area
Pressure= 1600/80
Pressure= 20 N/cm^2
For the four wheels, the pressure is
=20*4
=80N/cm^2

If you can get the money, the laboratory to use, the experimental
equipment, and the people you need to work on it with you, then
curiosity is a fine, honorable, and perfectly good reason to go ahead,
do what you gotta do, follow your heart, satisfy your curiosity, and learn
new stuff.
Neither the Large Hadron Collider, nor the Mars Rover, nor the Hubble
Space Telescope, nor the New Horizons probe, was built to cure cancer.
