Answer:
newtons
This constant ratio is called the coefficient of friction and is usually symbolized by the Greek letter mu (μ). Mathematically, μ = F/L. Because both friction and load are measured in units of force (such as pounds or newtons), the coefficient of friction is dimensionless.
Without counting wind resistance, They will both reach the ground at the same time. If we apply the concept of kinematics, such as the equation vf^2=vi^2 + 2ad. This equation doesn't count how big or how heavy the mass is, it only focuses on how fast where they in the start and how far are both of them from the ground. So if they both have the same distance and same initial veloctity, then they will reach the ground at the same time.
For example, Try dropping a pen and a paper(Vertically) at the same height, you'll see they'll reach the ground at the same time.
If you count wind resistance, the heavier ball will hit the ground faster, because the air molecules will resist the lighter ball compared to the heavier ball.
Answer:
A,
Explanation:
im going to choose a because they should probably still water it so it doesn’t die at least until it grows or gets a little bigger.
The main environmental effects of ozone depletion could include the following:
- higher risk of skin cancer
- sunburns
- quick ageing
- weakend immune system
<h3>What is ozone depletion?</h3>
Ozone depletion is the gradual thinning of the ozone layer in the upper atmosphere as a result of the relelase of chemical compounds or gases.
Ozone layer helps prevent the Earth surface against incoming ultraviolet radiations that could cause damage to our environment.
Therefore, the main environmental effects of ozone depletion could include the following:
- higher risk of skin cancer
- sunburns
- quick ageing
- weakend immune system

The true answer is C.
The boat is attracted to the magnet by the force of magnetism.
Let me explain. If Ashley made the paper boat and place it on the water, gravity will try to pull the boat down, however no magnets are used in this situation.
Now if magnets are used in this situation and the paper clip is attach to the boat, rather than gravity pulling it down, the magnet will be pulling paper clip, causing the boat to move, so instead of gravity, it's magnetism.
Note: Magnets=Magnetism
