You drive your car in a straight line at 15 m/s for 10 kilometers, then at 25 m/s for another 10 kilometers.
Vikki [24]

Answer:

A) Average speed = 18.75 m/s

B) More time is spent at 15 m/s than at 25 m/s.

Explanation:

Let the first distance be d1 and the second distance be d2.

We are given;

d1 = 10 km = 10000 m

d2 = 10 km = 10000 m

Speed; v1 = 15 m/s

Speed; v2 = 25 m/s

Now, the formula for distance is; Distance = speed x time

Thus:

d1 = v1 x t1

t1 = d1/v1 = 10000/15 = 666.67 seconds

Also,

d2 = v2 x t2

t2 = d2/v2 = 10000/25 = 400 seconds

Average speed = total distance/total time = (10000 + 10000)/(666.67 + 400) = 18.75 m/s

From earlier, since t1 = 666.67 seconds and t2 = 400 seconds, then;

More time at 15 m/s than at 25 m/s.

skelet666 [1.2K]

<u>Answer:</u>

"The Sun's diameter is about five times that of Earth" is not true about the sun.

<u>Explanation:</u>

The Sun at the pivotal of the solar system is a star and covers 99.86% of the total mass of the system. Approximately 73% mass of the sun is due to hydrogen gas while nearly 25% mass due to helium and for the remaining mass small amount of heavier elements like carbon, oxygen, neon and iron are responsible.

The diameter of the sun is 864,000 miles or 1.39 million km or 109 times of the Earth while mass is 330,000 times of the Earth's mass. Sun is a almost perfect sphere of hot plasma with internal convective motion responsible for production of a magnetic field through a dynamo process. And the most important source of energy on Earth for life.
