The international space station travels at a distance of about 250 miles above Earth’s surface and at a speed of 17,500 miles pe

r hour. Even though space dust and debris can be tiny, 1 centimeter or less in size with a mass of 10 grams or less, there is always fear that the space station will sustain damage from a collision with a small piece of space debris.
Why should scientists be concerned about a collision with such a tiny object? Use evidence and scientific reasoning to explain your answer.

Answer:

In this case we are dealing with the pythagorean theorm involving right angled triangles. This theorm states that a^2 + b^2 = c^2 which means the square of the hypotenuse (side c, opposite the right angle) is equal to the square of the remaining two sides.

In this case we will say that a = 3963 miles which is the radius of the earth. c is equal to the radius of the earth plus the additional altitude of the space station which is 250 miles; therefore, c = 4213 miles. We must now solve for the value b which is equal to how far an astronaut can see to the horizon.

(3963)^2 + b^2 = (4213)^2

b^2 = 2,044,000

b = 1430 miles.

The astronaut can see 1430 miles to the horizon.

I could use math to help with baking and measuring how much I should use for a cake or stuff like that, they also show us how to add our money together to help us with stuff.
Math, is helpful with many jobs, stuff learned in school can help you strategize and school also makes you think outside of the box sometimes, which can help with jobs. Also if you want to do a career with fashion designing or engineering, you can use math for that too. School also gives you the ability to read.

A bicycle has tires of radius 0.35 meters. If the bicycle is traveling at a constant speed of 7.8 m/s, at approximately what ang
lord [1]

22.3 rad/s

<h3>Further explanation</h3>

We will solve the question of uniform circular motion.

<u>Given:</u>

  • A bicycle has tires of radius \boxed{ \ R = 0.35 \ meters \ }
  • The bicycle is traveling at a constant speed of \boxed{ \ v = 7.8 \ m/s \ }

<u>Question:</u>

What angular speed are the tires rotating?

<u>The Process:</u>

Speed, angular speed, and radius are connected in the following formula:

\boxed{\boxed{ \ v = \omega R \ }}

The angular speed is worked out by

\boxed{ \ \omega = \frac{v}{R} \ }

All units are in the SI system so let us calculate the angular speed.

\boxed{ \ \omega = \frac{7.8 \ m/s}{0.35 \ m} \ }

Thus the value of the angular velocity of the rotating tire is \boxed{\boxed{ \ \omega = 22.3 \ rad/s \ }}

<u>An additional question:</u>

What is the frequency of tire rotation?

Recall this formula: \boxed{ \ \omega = 2 \pi f \ } \rightarrow \boxed{ \ f = \frac{\omega}{2 \pi} \ }

\boxed{ \ f = \frac{22.3 \ rad/s}{2 \pi} \ }

We get \boxed{\boxed{ \ f = 3.55 \ Hz \ }}

Answer:

7 s / 3600 s/hr = 0.001944444444... = 0.0019 hr

a = (vf - vi) / t = (70 - 0) / 0.0019 = 36000 km/hr²
