Answer:
1/√2
Explanation:
Kinetic energy of a body is expressed as
KE = 1/2mv²
If it's KE is doubled
2KE = 1/2mv1² where v1 is the new speed when the kinetic energy is doubled
To know the value of the amount the velocity has changed, we will divide both equations
2KE/KE = (1/2mv²)/(1/2mv1²)
2 = v²/v1²
(v/v1)² = 2
v/v1 = √2
v1 = v/√2
v1 = 1/√2 × v
The new velocity has changed by
1/√2vinitial
<span>The specific heat (or the amount of heat required to raise the temperature of a unit mass of a substance by 1 degree Celsius) of copper is about 0.386 J/g/degree Celsius. This means that if we supply 0.386 J of energy to 1 gram of copper, its temperature will increase by 1 degree Celsius.</span>
The tension in the string with friction would be the biggest because of the involvement of the force of gravity. This would result in that the friction force that is acting on the system. There is no friction in the frictionless system, and only the force of gravity is relevant.
