Answer: By eliminating waste through the cell membrane.
Explanation: Like humans, we use the bathroom. That's how that waste goes out. When you eat your food and chew it into small parts enough for you to swallow, your body starts to absorb and move the nutrients to where they need to go. When you drink water to flush your food down, your large intestine starts absorbing the water, and the waste products from the food you ate becomes stool. Then those Nerves and hormones help digestive the food/waste.
Answer:
Assuming that the masses of the cars are the same
9 times
Explanation:
Kinetic energy can be computed using the formula:
Where:
KE = Kinetic energy
m = mass
v = velocity
As you can see in your problem, the velocity of the the first car mentioned is 3 times faster.
Looking at the the formula, velocity is raised to two (2). So if we put it in terms of equations this is how it will look:
Let v = velocity of the slower car
Car 1: velocity = (3v)
The increase is by a factor of 9.
