A meteor is
Leya [2.2K]

Answer:

A meteor is  B) an icy body with a long tail extending from it.

Explanation:

Meteors are very small dust particles that, when penetrating into the Earth's atmosphere, burn quickly by rubbing with the gases of the same. Some meteors, those with larger dimensions and appreciable weights, are brighter and can describe longer trajectories, showing longer.

In other words, the meteoroids, celestial bodies can vary in size between 100 micrometers up to 50 meters, they collide with the atmosphere of our planet and if the particles are of a small size, upon impact they enter combustion creating a flash, is what we know as meteor or shooting star. Therefore, the meteor is a luminous phenomenon that leaves behind a persistent trail.

So, <u><em>a meteor is  B) an icy body with a long tail extending from it.</em></u>

What constant acceleration in si units must a car have to go from zero to 60 mph in 10s. what fraction of g is this?
Sophie [7]

The acceleration of the car in SI units is <u>2.68m/s².</u>

The acceleration is <u>0.27</u> times the acceleration due to gravity g.

Convert the speed in mph into m/s.

1 mile = 1609 m and 1h = 3600 s.

Therefore,

v=(\frac{60 miles}{1 h} )(\frac{1609 m}{1 mile} )(\frac{1h}{3600s)} =26.82m/s

Acceleration is the rate of change of velocity. The car starts from rest , its initial velocity u = 0 and accelerates to a velocity v of 26.82 m/s in 10 s.

Use these values in the equation and calculate the acceleration.

a=\frac{v-u}{t} \\ =\frac{(26.82 m/s)-(0m/s)}{10s} \\ =2.682 m/s^2

Thus the car accelerates at a rate of <u>2.68 m/s².</u>

The acceleration due to gravity g on Earth has a value 9.81 m/s².

Find the ratio\frac{a}{g}

\frac{a}{g} =\frac{2.682m/s^2}{9.81m/s^2} \\ =0.27&#10;a=0.27g

The car's acceleration is <u>0.27 times the value of g.</u>
