1.What is the gravitational potential energy for an apple ( m = 167.00 g) if it's located at H = 3.2 m on a tree? ( assume )

(Round your answer in two decimal places and do not add units and assume g = 10 m/s²)

2.How much energy do we need to add to 18Kg of Copper to increase its temperature from 300 Kto 350K?

( Specific Heat for Copper C = 0.386 j/g K = 386 j/Kg K)

		347.4 j
		347400 j
		34740 j
		3474 kj

3.Which one is correct regarding the Temperature and Heat?

		Temperature and Heat are the same as Thermalenergy
		Temperature is a scalar quantity and it's a measure of warmth or coldness Heat is a form of energy that can be transferred between two objects if they are at different Temperatures.
		Temperature is a scalar quantity and it's a measure of warmth or coldness and the amount of their energy. Heat is aform of energy that can be transferred between two objects if they are at different Temperatures.
		The warmer ( High Temperature) object always has a higher amount of thermal energy compared to a cold ( Low Temperature) object.
