Help me pleaseee...A 200kg piano sitting on a platform 2 m high has 3920 J off potential energy. It required 4500 J of work to push the piano up a ramp to the platform. What is the best explanation for the difference between the amount of work required to move the piano and its potential energy? A) the piano lost mass as it was pushed up the ramp.B) energy was destroyed moving the piano up the ramp.C) some of the energy required to push the piano up the ramp was used to overcome friction between the piano and the ramp.D) the work required to push the piano up a ramp is greater because the force is the same as if it were lifted, but the distance is greater when using a ramp.

Heat Energy can be transferred from a source to a receiver by

Answers

Heat energy can be transferred from a source to a receiver by conduction, convection and radiation.

What are three methods of heat transfer and what are some examples

Answers

Answer: I am studying heat transfer and have learned there are three kinds of heat transfer: conduction, convection, and radiation. Some examples are:

Conduction:

Touching a stove and being burned

Ice cooling down your hand

Boiling water by thrusting a red-hot piece of iron into it

Convection:

Hot air rising, cooling, and falling (convection currents)

An old-fashioned radiator (creates a convection cell in a room by emitting warm air at the top and drawing in cool air at the bottom).

Radiation:

Heat from the sun warming your face

Heat from a lightbulb

Heat from a fire

Heat from anything else which is warmer than its surroundings.

Explanation: A good example would be heating a tin can of water using a Bunsen burner. Initially the flame produces radiation which heats the tin can. The tin can then transfers heat to the water through conduction. The hot water then rises to the top, in the convection process.

The atmosphere would be another example. The atmosphere is heated by radiation from the Sun, the atmosphere exhibits convection as hot air near the equator rises producing winds, and finally there is conduction between air molecules, and small amounts of air-land conduction.

What information does the atomic mass of an element provide? A. the sum of electrons and protons in an atom B. the difference between the number of protons and electrons C. the number of protons and neutrons in an atom D. the number of isotopes

Answers

C...

the atomic mass denotes the sum of the subatomic particles in a nucleus of an atom (neutron & proton).... the reason why the electron is not included is because it is very light and thus thought to be negligible.

Explanation:

A weight machine ____.A) Decreases the amount of input force required

B) reduces the amount of input work

C) changes the direction of the input force

D) increases the input distance

Answers

C) changes the direction of the input force

Explanation:

A weight machine measure the normal reaction of a body place on the machine.This means the force will have no acceleration. The body placed on the machine will thus exert the force due to gravity and the normal reaction will act in the opposite direction to it.
