James Prescott Joule demonstrated that work could generate heat using his churn. In order to truly demonstrate that energy is co

nserved, the next logical step would have been to convert that heat entirely back to work. why was this not done?

Answer:

Heat can be converted into work as that is the principle on which steam turbines work and generate electricity. But in order to achieve the result we need to modify the apparatus in such a way that heat is extracted from the fluid whose temperature increases due to churning. This requires a modified setup which is different from the one used by Joule. The relationship that work can be converted into heat and vice versa both requires different apparatus to be accomplished as a machine can act as either as one that does work or one on which work can be done.

Two 10 kg pucks head straight towards each other with velocities of 10 m/s and -20 m/s. They collide and stick together. Calcula
RUDIKE [14]

The final velocity of the two pucks is -5 m/s

Explanation:

We can solve the problem by using the law of conservation of momentum.

In fact, in absence of external force, the total momentum of the two pucks before and after the collision must be conserved - so we can write:

m_1 u_1 + m_2 u_2 = (m_1 +m_2)v

where

m_1 = m_2 = m = 10 kg is the mass of each puck

u_1 = 10 m/s is the initial velocity of the 1st puck

u_2 = -20 m/s is the initial velocity of the 2nd puck

v is the final velocity of the two pucks sticking together

Re-arranging the equation and solving for v, we find:

mu_1 + mu_2 = (m+m)v\\u_1 + u_2 = 2v\\v=\frac{u_1+u_2}{2}=\frac{10-20}{2}=-5 m/s
