<h3>What is Free-fall acceleration?</h3>
The acceleration is constant and equal to the gravitational acceleration g which is 9.8 m/s at sea level on the Earth.
As we know that charge and its sign that remains in equilibrium is under gravity must be such that it will balance the gravitational force by electric force,
mg =qE

and its sign must be negative so that it will have upward electric force
so it is

The charge of a particle of mass is

Answer:
The brick would heat up the fastest.
Explanation:
Bricks are thick but they absorb sunlight at an alarming rate.
The species is actually endangered and not extinct because there are only 20 species left. Extinct actually means that there would be no species left and so it an incorrect option. The correct option among all the options that are given in the question is the second option or option "B". I hope the answer has helped you.
Answer:
- The formula its

- After 5 years, the computer value its $ 1056
Explanation:
<h3>
Obtaining the formula</h3>
We wish to find a formula that
- Starts at 2816.

- Reach 0 at 8 years.

- Depreciates at a constant rate. m
We can cover all this requisites with a straight-line equation. (an straigh-line its the only curve that has a constant rate of change) :
,
where m its the slope of the line and b give the place where the line intercepts the <em>y</em> axis.
So, we can use this formula with the data from our problem. For the first condition:


So, b = $ 2816.
Now, for the second condition:





So, our formula, finally, its:

<h3>After 5 years</h3>
Now, we just use <em>t = 5 years</em> in our formula
