Answer:
A. absorb heat energy and move farther apart
Explanation:
The answer is A since when a ice cube takes in heat, it changes form and melts down to a liquid : water.
The molecules in water are farther apart since they are moving around alot but can be contained in a container.
Energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object.
The law of conservation of energy<span>, a fundamental concept of physics, states that the total amount of </span>energy<span> remains constant in an isolated system. It implies that </span>energy<span> can neither be created nor destroyed, but can be change from one form to another.</span>
Answer:
e.26m/s
Explanation:
Vf=Vi+at (1)
Vf=9j+(2i-4j)t
X= X₀+at
now, in the i direction
15=O+2t or t=7.5 when x position is 15
Lets put that into the (1) equation, solve for Vf.
Vf=9j+(2i-4j)7.5
Vf= 15i - 21j
Speed= 
Vf= 25.8 m/s
