Which process can transfer energy to a solid metal block

Eneregy is the ability to to do work it takes work to heat someone heat is energy put the solid metal block in a campfire and heat it up tada wait, we need the options, nevermind

-- Heat conduction can, like when you put a hot iron down
on the metal block.

-- Radiation can, like when you put the block outside
in the sun.

-- Electric current can, like when you connect wires from
the block to both terminals of a battery.

-- Doing mechanical work on it can, like when you carry the block
upstairs to your bedroom, giving it gravitational potential energy.

-- Motion can, like when you drop the block out of your bedroom
window, and the force of gravity gives it kinetic energy.

the simple machine has three main features. they are:

loadfulcrumeffort

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are
