A gram of gold's density is g/ml. If the mass is multiplied by 1000 to get to kg, so is ml. This gives kg/liter as the density. For example, if the density was 2g/ml. the density would still be 2kg/l.
The kinetic Energy has to be the same as the Energy with which the spring was stratched:
1/2×m×v^2=1/2×D×s^2
Ekin=1/2×440×0.3^2= 1/2×440×0.09=19.8. ( Of course, the kinetic Energy is normally Not calculated Like this , but in this case both Formulas have the Same solution so you can Wright it Like This)
By the way, if the spring Had Not reached its Natural length yet, you wouldnt be right if you calculate it Like above, because a Part of the Energy is still in the spring : Espring=Ekin+Espring2
Answer:
Yes.
Explanation:
Yes, this system transmitting energy between your bodies because everybody is in thermal equilibrium with other body. Thermal equilibrium occurs when there is same amount of thermal energy is gained by the body and same amount of energy lost by the body so there is no increase or decrease occur in the thermal energy of each body so we can say that the system transmitting energy between the bodies.

I believe he made a theory that light was electromagnetic radiation
Answer:
H = 5.35 cm
Explanation:
As per energy conservation we know that energy stored in the spring is converted into gravitational potential energy when it is reached at the top
now we have
here we know that
m = 1 kg
k = 105 N/m
x = 0.1 m
now plug in all data in it
now solving for height H we have
