Both hits the ground <u>at the same time</u> because they have <u>same vertical acceleration</u>

<h3>What is vertical acceleration?</h3>
A vertical acceleration is typically one for which the direction of the vector is vertically upward, usually aligned with and opposite to the gravity vector. But this is a descriptive term, not a rigorous or technical term. A car may accelerate along a road and that would generally be assumed to be a horizontal.
The vector perpendicular to this direction, as perhaps a suspension motion over a bump, would be described as vertical even if it is not strictly vertical.
Note that acceleration is defined as the rate of change of the velocity vector. But the gravitation vector, ‘g’, generally vertically downward, is often denoted by what acceleration a mass in free fall (absent air resistance) would experience, i.e. the relationship between mass and weight.

Answer:
photosynthesis, burning fossil fuels, and simply releasing breath from the lungs.
Answer:
The answer is
<h2>7,840,000 J</h2>
Explanation:
The kinetic energy KE of an object given it's mass and velocity can be found by using the formula
where
m is the mass
v is the velocity
From the question
m = 20000kg
v = 28 m/s
It's kinetic energy is
We have the final answer as
<h3>7,840,000 J</h3>

Answer:
Chemical energy
Explanation:
The energy held in the foods molecules a lunch pack is composed of is chemical energy.
They occur within food substances which originates from plants and animals as giant organic molecules.
- Since food is often derived from plants and animals.
- Plants produce their own food by producing macromolecules from simple inorganic substances in the environment.
- Animals takes up these food and build their own body through it.
- Plants and animal parts constitutes organic molecules in which chemical energy is duly stored.
- When the molecules are broken down, they released their chemical potential energy into heat energy.
Answer:
It is B
it is called a jumper cable because it jumps the power from one car to the other
