why knowing how to graph movement can help you on a practical level?

Answer: 4 m/s

Explanation:

The scooter's velocity after 2 seconds of its start will be 4 m/s.

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.

They are all non-metallic elements

According to the electronic configuration, elements which will most likely form anions sulfur and fluorine .

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

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.

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:

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.

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.

Answer:

They pass each other at 2415.79 m relative to the starting point.

Explanation:

Let s represent the distance moved by the car.

Since they are 900 m apart, it starts from rest and the truck moves at an acceleration of a = 3.2 m/s², we use

s - s₀ = ut + 1/2at²      u = initial velocity = 0 (since it starts from rest) and s₀ = 900

s = 900 + 1/2 × 3.2 m/s² × t²

s = 900 + 1.6t²

Let s' represent the distance moved by the motorcycle.

Since it starts from rest and the motorcycle moves at an acceleration of a = 5.1 m/s², we use

s' - s₀' = ut + 1/2at²      u = initial velocity = 0 (since it starts from rest) and s₀' = 0 (the starting point of the motorcycle)

s' = 0 + 1/2 × 5.1 m/s² × t²

s' = 2.55t²

At the point where they pass each other, s' = s

2.55t² = 900 + 1.6t²

collecting like terms, we find the time which they meet each other

2.55t² - 1.6t² = 900

0.95t² = 900

t² = 900/0.95

t = √(947.37)

t = 30.78 s

Substituting t into s', we have

s' = 2.55t²

= 2.55(30.78)²

= 2.55(947.37)

= 2415.79 m

So, they pass each other at 2415.79 m relative to the starting point.

Explanation:

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.
