Answer:
hi,human absorb 0oxygen =aborption ,reflection =the light that entered in the water,refraction =the light that pass outside the water
Explanation:
The leaf fell at the crooked path instead of straight down because air currents and gravity applied changing and unbalanced forces to the leaf.
<h3>What is an air current?</h3>
An air current is defined as the changes in atmospheric pressure that causes the movement of air from one area to another.
When a leaf is detached naturally from the tree, it won't fall straight down to the floor but will fall a distance away from the tree due to the action of air current and some unbalanced forces.

All cops are brave. And what’s the full question?
The amount of time that passes from when this skateboarder begins to slow down until she begins to move back down the incline is 8.75 seconds.
<u>Given the following data:</u>
- Acceleration = -0.2

To calculate the amount of time that passes from when this skateboarder begins to slow down until she begins to move back down the incline, we would apply the first equation of motion;
<h3>
The formula for the first equation of motion.</h3>
Mathematically, the first equation of motion for a decelerating object is given by this formula;

<u>Where:</u>
- t is the time measured in seconds.
Substituting the given parameters into the formula, we have;

Time, t = 8.75 seconds.

If 1 second = 10000 μs
what about how many seconds = 0.77 μs
the calculations would be done lke this
0.77 x 1/1000000 = 7.7 x 10 ^ -7
Speed = distance / time
distance = length of the spacecraft
therefore speed = 250/7.7 x 10^ -7
ans = 324675324.7 m/s
