Answer:
a).
b).
Explanation:
a).
Using the law of thermodynamic and using to isovolumetric
ΔU=Qh
So to determine the internal energy knowing the work it do
b).
Efficiency is the work done in relation of the work apply in this case to produce heat so:
Solve to Qc
Answer:
Elastic collision
Explanation:
The interaction of two particles is called collision. There are two types of collision i.e. elastic collision and inelastic collision.
Two bouncy balls colliding with each other is an example of elastic collision. In this type of collision the momentum and kinetic energy of the bodies remains constant i.e.
and
Where
m₁ and m₂ are masses of two balls A and B
u₁ and u₂ are initial velocities of ball A and B
v₁ and v₂ are final velocities of ball A and B
The lifetime of a star is determined by its mass. The larger it’s mass, the shorter it’s lifetime
Answer:
Momentum, p = 5 kg-m/s
Explanation:
The magnitude of the momentum of an object is the product of its mass m and speed v i.e.
p = m v
Mass, m = 3 kg
Velocity, v = 1.5 m/s
So, momentum of this object is given by :
p = 4.5 kg-m/s
or
p = 5 kg-m/s
So, the magnitude of momentum is 5 kg-m/s. Hence, this is the required solution.
