Answer:
a large truck that moves fast
Explanation:
look at the question and look how it says (more momentum) which means faster and more force
Answer:
W = - 118.24 J (negative sign shows that work is done on piston)
Explanation:
First, we find the change in internal energy of the diatomic gas by using the following formula:
where,
ΔU = Change in internal energy of gas = ?
n = no. of moles of gas = 0.0884 mole
Cv = Molar Specific Heat at constant volume = 5R/2 (for diatomic gases)
Cv = 5(8.314 J/mol.K)/2 = 20.785 J/mol.K
ΔT = Rise in Temperature = 18.8 K
Therefore,
Now, we can apply First Law of Thermodynamics as follows:
where,
ΔQ = Heat flow = - 83.7 J (negative sign due to outflow)
W = Work done = ?
Therefore,
<u>W = - 118.24 J (negative sign shows that work is done on piston)</u>
Answer:
4 %
Explanation:
mass of the object 1, m₁ = 0.1 Kg
initial velocity of object 1,v₁= 0.2 m/s
mass of object 2, m₂ = 0.15 kg
initial speed of the object 2. v₂ = 0 m/s
Kinetic energy retained by the object 1 = ?
using the formula to calculate velocity of the ball after collision
negative sign represent the velocity is in opposite direction after collision.
Initial KE
final KE
% of KE retained
=
=
= 4 %
the percentage of Kinetic energy retained after collision is equal to 4 %
