Answer:
A unit is represented in kWH or Kilowatt Hour. This is the actual electricity or energy used. If you use 1000 Watts or 1 Kilowatt of power for 1 hour then you consume 1 unit or 1 Kilowatt-Hour (kWh) of electricity.
Answer:
ωf = 4.53 rad/s
Explanation:
By conservation of the angular momentum:
Ib*ωb = (Ib + Ic)*ωf
Where
Ib is the inertia of the ball
ωb is the initial angular velocity of the ball
Ic is the inertia of the catcher
ωf is the final angular velocity of the system
We need to calculate first Ib, Ic, ωb:
ωb = Vb / (L/2) = 16 / (1.2/2) = 26.67 m/s
Now, ωf will be:
Answer:
Heating
Cooling
Water Heater
Washer and Dryer
Lights
Explanation:
mark as brainliest and drop some thanks!!
Is the same as the amount that is used to make the chemical reaction. The Law of conservation of Matter states that matter cannot be added or removed, or created or destroyed. This means that the amount of matter is always the same
hope this helps
