Forget the numbers and think about how speed works for a second. If a plane flies at 600km/h, this means that it will fly exactly 600 km in 1 hour. So, how long would it take to fly 2400 km??
2400/600 = 4hours.
Do this for all three and add up the hours.
Total time: 12 hours
Average speed is the total distance / total time.
So,
Add up all the distances and divide by 12.
(2400+1200+2500) / 12
Average speed: 508.33333333 km/h
The net force acting on the car is equal to -12000 Newton.
<u>Given the following data:</u>
- Initial velocity = 30 m/s.
- Final velocity = 0 m/s (since the car came to a stop).
To determine the net force acting on the car:
<h3>How to calculate the net force.</h3>
Mathematically, the net force acting on the car is given by Newton's Second Law of Motion:
<u>Where:</u>
- u is the initial velocity.
Substituting the given parameters into the formula, we have;
Net force = -12000 Newton.

Answer:
3875J
Explanation:
Energy is defined as the power × time
And it's defined as
Power = IV - I- current and V- voltage
Now quantity of electricity; Q = I × t
Where I is current and t is time
Now Energy = I ×V×t = V× I×t = V× Q;
where Q is quantity of electricity 775C and V is 5.0volt
Hence 775 × (5) =3875J

Answer:
See Explanation
Explanation:
The density of a substance is an intrinsic property. Intrinsic properties are properties that are characteristic of a material. It does not depend on the amount of substance present.
Since density is an intrinsic or intensive property, If you cut a piece of gold in half, the density of each piece will still be 19.32 g/cm 3 because density does not depend on the size of the gold piece.
