Answer:

The answer is below

Explanation:

Jenny and anne wanted to see who could throw the ball the hardest. they decided to each throw a ball against the wall as hard as they could and measured how far the ball rolled away from the wall. what might be the variables in this experiment;

Solution:

There are different type of collisions. In an inelastic collision, momentum is conserved and there is loss in kinetic energy while in an elastic collision, momentum is not conserved and there is no loss in kinetic energy.

During inelastic collision, the objects stick together while during an elastic collision, the objects separate.

When the ball is thrown against the stationary wall, there is momentum due to the force of impact. The distance at which the ball is rolled away from the wall depends on:

a) mass of the ball, b) velocity of the ball, c) mass of the wall d) type of collision (elastic or inelastic)

Answer:

The efficiency of a Stirling engine is 74%

Explanation:

Given:

Temperature of gas when it is cold T_{1} = 78 K

Temperature of gas when it is hot T_{2} = 300 K

The efficiency of a stirling engine,

  \eta =1 - \frac{T_{1} }{T_{2} }

  \eta = 1- \frac{78}{300}

  \eta = 1-0.26

  \eta = 0.74

∴ \eta = 74 \%

Therefore, the efficiency of a Stirling engine is 74%

A system expands from a volume of 1.00 l to 2.00 l against a constant external pressure of 1.00 atm. what is the work (w) done b
stepan [7]
The work done by a system kept at constant pressure is given by:
W=p \Delta V = p (V_f - V_i)
where
p is the pressure
V_f is the final volume
V_i is the initial volume

If we plug the numbers given by the problem into this equation, we find
W=p (V_f -V_i)=(1.00 atm)(2.00 L-1.00 L)=1.00 L\cdot atm

And since 1 atm \cdot L = 101.3 J, we have that the work done is
W= 1.00 atm \cdot L = 101.3 J
