How far does a freely falling apple drop in 5.1 s after being released from rest?
Answer:
122.5 meters
Explanation:
g = 9.8 m/s^2 (standard value of g). so the freely falling body fall during the first 5 seconds will fall 122.5 meters if there is no external force work on it in an standard environment
The distance traveled by the apply after being released is 127.45 m.
The given parameters;
time of motion of the apple, t = 5.1 s
initial velocity of the apple, u = 0
The distance traveled by the apply is calculated by applying second kinematic equation as shown below.
Assuming downward motion to be positive.
[tex]s = ut + \frac{1}{2} gt^2\\\\s = 0 + 0.5\times 9.8 \times 5.1^2\\\\s = 127.45 \ m[/tex]
Thus, the distance traveled by the apply after being released is 127.45 m.

Ms. Reitman's scooter starts from rest and accelerates at 2.0 m/s2
What is the scooter's velocity after 2 s?
Answer: 4 m/s
Explanation:
The scooter's velocity after 2 seconds of its start will be 4 m/s.
State first equation of motion?
The first equation of motion is -
v = u + at
Given is Ms. Reitman's scooter that starts from rest and accelerates at
2 m/s².
We can write -
[a] = 2 m/s²
[t] = 2 s
Using the first equation of motion, we can write -
v = u + at
v = 0 + 2 x 2
v = 4 m/s
Therefore, the scooter's velocity after 2 seconds of its start will be 4 m/s.

When the units are smaller,
we need (more / less) of them.
Answer:
more..................
Answer:
If you are referring units to the metric system, I think the answer would be less.
(I'm not completely sure)
Explanation:
I say this because for example, if you have a prescription for 5,000 mg of medicine, and upon getting it filled, the dosage than decimeters (dm), so you expect there to be more than one dm in a km. (Since you are going from a larger unit to a smaller unit, you multiply). Meters is larger than centimeters, so you expect your answer to be less than 7,225.

An independent variable is ______________________and is plotted on the ______ axis
A dependent variable is ________________________ and is plotted on the ______ axis.
Answer:
The independent variable is plotted on the abscissa (also called the x-axis or horizontal axis), while the dependent variable is plotted on the ordinate (also called the y-axis or vertical axis). The dependent variable is the one whose value changes as a result of changes in the independent variable.

2. How have human activities and natural processes influenced the gradual or sudden change in global temperature? (You need a minimum of 5 complete sentences.)
Answer:
Human activities and natural processes have influenced the change in the global temperature by the following processes
1) Green house gas such as carbon dioxide, methane, ozone, nitrous oxide and fluorinated gases produced by the combustion of fossil fuels the use of industrial chemicals, the production of coal, and natural gas
2) Deforestation which reduces the natural process of conversion of carbon dioxide to oxygen, thereby, increasing the greenhouse gases in the atmosphere
3) The accumulation of the greenhouse gases in the atmosphere results in the trapping of heat in the atmosphere, causing the atmospheric temperature to rise
4) Changes in the amount of energy produced by the Sun can result in an increase or decrease in the atmospheric temperature
5) Volcanic activity that occurs at a sufficiently large scale can produce sulfur dioxide that blocks the rays of the Sun from reaching the Earth, resulting in a change of atmospheric temperature.

Answer:
Green house gas such as carbon dioxide, methane, ozone, nitrous oxide and fluorinated gases produced by the combustion of fossil fuels the use of industrial chemicals, the production of coal, and natural gas

How long will it take for a rock to fall 12 meters?
Answer:
1.56 seconds.
The rock will take 1.56 seconds to fall.
We have a rock.
We have to determine how long it will take for a rock to fall 12 meters.
State the second equation of motion.The second equation of motion is -
S = ut + 1/2 at²
According to the question -
initial velocity = u = 0 m/s
acceleration = a = 9.8 m/s²
distance = S = 12 meters
Using the second equation of motion -
S = ut + 1/2 at²
12 = 0 + 0.5 x 9.8 x t²
12 = 4.9t²
t² = 2.45
t = 1.56 seconds
Hence, the rock will take 1.56 seconds to fall.

Answer: Uranus 8.7
Explanation:
Because mass does not effect the velocity of a falling object, only gravity effects it and time. The equation is change in Velocity= 9.8m/s^2 times t (for time). So, ignore the mass and choose the lowest acceleration in the chart if your question asks you for the lowest speed.
