-- If it's all happening horizontally, then gravity is not involved.
Only the spring is.
-- If there's no friction, then total energy is conserved.
-- If you put 190J of energy into the spring by moving the mass,
and there's only 55J of potential energy in the spring now, then
the other 135J of energy is in the kinetic energy of the mass and
the moving parts of the spring.
Hello!
If you are referring to the mercury substance, mercury is a bright red color, usually used in early thermometers and is deadly if humans have a lot of constant with this substance
Answer:
48m
Explanation:
- Initial velocity = 4m/s
- Acceleration = 4m/s²
- Time = 4s
- Displacement = ?
From Second equation of motion ,
s = ut + 1/2at²
s = 4*4 + 1/2*4*(4)² m
s = (16 + 2 * 16) m
s = ( 16 + 32 )m
s = 48 m
Answer:
C. Decreasing the distance between the objects.
Explanation:
Gravitational force depends on mass and distance. The farther the objects are apart, the less gravitational force/pull they have.
