She can monitor her practice run times to see if they are decreasing.
Answer:
the answer is C
Explanation:
C) friction - mechanical - electrical
<span><em>Continental drift</em> is one of the earliest ways that geologists thought <em>continents</em><span> moved
over time. It is believed in this theory that the Earth’s movement of the
continents are relative to each other.
This idea was subsumed by the plate tectonics theory. Now, what is the
speed of the continental drift?</span></span>
Continental drift speed is 1x 10^-9 m/s.
This is equivalent to a speed of:
1 x 10 ^-9 m/s
= 1 x 0. 000 000 000 1 m/s
= 0. 000 000 000 1 m/s
Answer:
The new volume of the balloon is 8.8 L
Explanation:
Charles's Law consists of the relationship between the volume and the temperature of a certain amount of ideal gas, which is kept at a constant pressure. This law establishes that the volume is directly proportional to the temperature of the gas, that is to say that if the temperature increases, the volume of the gas increases and that on the contrary if the temperature of the gas decreases, the volume decreases.
In other words, Charles's law states that when the amount of gas and pressure are kept constant, the ratio between the volume and the temperature will always have the same value:
Having a certain volume of gas V1 that is at a temperature T1, by varying the volume of gas to a new value V2, then the temperature will change to T2, and it will be fulfilled:
In this case:
- V1= 8.5 L
- T1= 294 K
- V2= ?
- T2= 305 K
Replacing:
Solving:
V2=8.8 L
<u><em>The new volume of the balloon is 8.8 L</em></u>
The interaction of light that distorted the image of where Bill's goggles appear to be is Refraction.
<h3>
What happens to the speed of light when it hits water in a swimming pool?</h3>
The light slows down when it passes from the less dense air into the water, this slow down of the ray of light which causes the ray of light to change direction and then the changes the speed of the light that causes refraction.
The swimming pool appears shallow than it appear to be because the rays of light coming from the bottom of the swimming pool that is refracted by the water making the height of the swimming pool to be above the actual swimming pool bed and there by misleading the observer(Bill).
