solid
Explanation:
because it has a definite shape and volume
Well, first of all, the car is not moving at a uniform velocity, because,
on a curved path, its direction is constantly changing. Its speed may
be constant, but its velocity isn't.
The centripetal force on a mass 'm' that keeps it on a circle with radius 'r' is
F = (mass) · (speed)² / (radius).
For this particular car, the force is
(2,000 kg) · (25 m/s)² / (80 m)
= (2,000 kg) · (625 m²/s²) / (80 m)
= (2,000 · 625 / 80) (kg · m / s²)
= 15,625 newtons .
Scientists gather a new evidence like let me say for example jj Thompson said that an atoms is the least particles of an element but according to our definition an atom is the smallest particles of an element so you see
I hope it will help you...
no. energy is not created or destroyed, just transformed.
a hot light source is less efficient than a cold one ... heat is not light ...
