I believe that is true, yes!
Answer:
The final velocity is 8 m/s and its direction is along the positive x-axis
Explanation:
Given :
Mass, m₁ = 2000 g = 2 kg
Mass, m₂ = 4000 g = 4 kg
Initial velocity of mass m₁, v₁ = 24i m/s
Initial velocity of mass m₂, v₂ = 0
According to the problem, after collision the two masses are stick together and moving with same velocity, that is, .
Applying conservation of momentum,
Momentum before collision = Momentum after collision
Substitute the suitable values in the above equation.
I think that peeing might be the correct answer? xD
The amount of thermal energy required to convert 1.75 kg of solid copper at 1358 K to liquid at 1358 K is 360.5 KJ
Q = m *
Q = Thermal energy
m = Mass
= Latent heat of copper
m = 1.75 kg
= 206 KJ / kg
Q = 1.75 * 206
Q = 360.5 KJ
Thermal energy is a type of energy that is responsible for a system's temperature. The flow of thermal energy is called as heat.
Therefore, the amount of thermal energy required is 360.5 KJ
