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.
Answer:
carpal, metacarpal, and phalange
Answer:
An otter's den is called a holt or couch.
Explanation: Otters are found almost all over the world and in many wet habitats, such freshwater rivers, lakes, oceans, coastlines and marshes. Most otters live in dens — built by other animals, such as beavers — that are dug into the ground that have many channels and dry inner chambers
You should only change one factor in an experiment, so that if something different happens, you know what probably caused it.
