Answer: Stars die when their nuclear fuel runs out.
Explanation:
Answer:
The temperature would fall.
Explanation:
The question can be solved by using first law of thermodynamics.
The law states:
The change in internal energy of the system is equal to the heat energy supplied to the system minus the workdone by the system.
ΔU = Q - W
where ΔU is change in internal energy of the system
Q is energy given to the system
W is workdone by the system
Because the charges are repelling each other it means they will move away from each other and their repulsive forces will do positive workdone (workdone is defined as distance moved in the direction of the force applied). Therefore W > 0.
There is no energy supplied to the system so Q = 0.
Using the relation ΔU = Q - W we can see that if Q = 0 and W > 0 then ΔU < 0. Hence internal energy of the system falls so the temperature falls.
<span>The collision produces forces between the car and the bug. These forces depend on the momentums of the objects that collide.
Momentum is the product of mass and velocity. The greater the mass the smaller the acceleration. That is the Newton's second law. Because the mass of the car is greater, it's momentum is also greater and the accelaration is smaller. so, the bigger momentum of the car explains the different damage.</span>
Answer:
40 units
Explanation:
200 divided evenly by 5 is 40. Therefore there are 40 units
It is impossible for a dt-graph to have a vertical line. This would mean that you are at many places at one point in time. It simply can't be done, because we can't teleport lol. You can, however, have a line that is REALLY steep. This would mean that you're travelling really fast. (Covering large amounts of distances in short spans of time) Hope this helped!
