Answer:
Kinetic energy increases and potential energy decreases
Explanation:
Because kinetic energy is proportional to the square of the velocity, when velocity is doubled, kinetic energy is quadrupled. Kinetic energy K=mv^2/2. Kinetic energy is the energy of movement or change. Potential energy is the energy a system has as a result of being able to undergo some change. ... As an object falls its potential energy decreases, while its kinetic energy increases. The decrease in potential energy is exactly equal to the increase in kinetic energy.

Answer: C. 7.67 W </h2>
Explanation:
Firstly, we are told the three resistors are <u>connected in parallel</u>, this means we have to use the following equation to find the total resistance 
of the circuit:
(1)
Where: 
, 
, 
Solving (1):
(2)
(3)
(4) This is the total resistance of the circuit
On the other hand, the total power 
of this circuit is given by the following equation:
(5)
Where 
is the total voltage of the circuit.
Solving:
(6)
Finally:
(7) This is the total power of the circuit in Watts (W)
As for me, <span>the way how might building a new highway affect the cycles of matter can be revealed by cutting resourses. To be more exact, </span>plants should be cleared which means that food and energy and so on will be limited and can cause delay in recycling.
Hope it helps!
