Answer: The reflected ray will be 44 degrees.
Explanation: The Law of Reflection states the angle of incidence ( the incoming light ray) equals the angle of reflection ( the light ray being reflected) Therefore, the angle of reflection will be 44 degrees.
Hope that helped!
Answer:
A= 203 KJ
B= 54 Kg
Explanation:
The initial specific volumes and internal energies are obtained from A-12 for a given pressure and state. The enthalpy of the refrigerant in the supply line is determined using the saturated liquid approximation for the given temperature with data from A-11. The mass that has entered the tank is:
Δm = m₂ – m₁
= V(1/α₂ – 1/α₁)
= 0.05 (1/0.0008935 – 1/ 0.025645)Kg
= 54Kg
The heat transfer is obtained from the energy balance:
ΔU= 
+ 
m₂u₂ – m₁u₂ = +
= m₂u₂ – m₁u₁ –
= V/α₂u₂ - V/α₁u₁ –
=(0.05/0.0008935 . 116.72 – 0.05/0.025645 . 246.82 – 54.108.28) Kj
= 203 KJ
When the piece of metal blundered into the air-core coil, it changed the inductance of the coil.
Answer:
B.) A disturbance that carries energy
Explanation:
The complete statement that describes a wave would be :
A wave is a disturbance that carries energy from one place to another
