Formula for acceleration: a = v-v0/t
a is acceleration, v is final velocity and v0 is starting velocity, t is time
Now plug it in
a = 50m/s - 30 m/s = 20 m/s/ 5s = 4 m/s^2
The acceleration is 4 m/s^3
Answer:
The height of mountain in meter will be 106.2732 m
Explanation:
We have given height of mountain = 348 ft,8 in
We know that 1 feet = 0.3048 meter
So 348 feet 
And we know that 1 inch = 0.0254 meter
So 8 inch 
So the total height of mountain in meter = 106.07+0.2032 = 106.2732 m
The height of mountain in meter will be 106.2732 m
<h3><u>Answer;</u></h3>
C. 12 units
<h3><u>Explanation;</u></h3>
- If the strength of the magnetic field at B is 3 units, the strength of the magnetic field at A is 12 units
- Magnetic field strength is one of two ways that the intensity of a magnetic field can be expressed.
- <em><u>The strength of the field is inversely proportional to the square of the distance from the source. This means that If the distance between two points in magnetic filed is doubled the magnetic force between them will fall to a quarter of the initial value. </u></em>
- <em><u>On the other hand, if the distance between two magnets is halved the magnetic force between them will increase to four times the initial value.</u></em>
The answer is b because the sun's surface temperature is 5,778 K.
If n=1 you divide by 2
If n=2 you divide by 4
If n=3 you divide by 8
so any n you divide by 2 to the power n
