If an object has 50 Joules of kinetic energy and 237 joules of potential energy, how much mechanical energy does it have? ME = PE + KE

287J

Explanation:

Given parameters:

Kinetic energy = 50J

Potential energy = 237J

Unknown:

Mechanical energy  = ?

Solution:

The mechanical energy of a system is the sum of the potential energy and kinetic energy of that system.

  Kinetic energy  = Potential energy + Kinetic energy

  Kinetic energy  = 50J + 237J  = 287J

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do
