Answer:
A prism is a clear crystal that refracts light
Explanation:
I have a hunch that you've got the <em>question</em> totally covered, and what you actually need is the <em>answer.</em>
- Kinetic energy = (1/2) (mass) (speed²)
Multiply each side by 2 : 2 x KE = (mass) ( speed²)
Divide each side by (mass): Speed² = 2 x KE / mass
Square root each side: <em>Speed = √(2 KE/mass)</em>
Look at that ! The question GIVES you the KE and the mass. All you have to do is plug those 2 numbers into the right side of that equation, turn the crank, do the arithmetic, and the speed falls out.
I get 200 m/s . You need to check my work.
(IF that's correct or anywhere close, it's equivalent to something around 447 miles per hour, which is very reasonable for a cruising airliner.)
Answer:
The two space stations are 644.1653 miles far apart.
Explanation:
The distance of Huston and the International Space Station is 323 miles.
The distance of Huston and the Chinese space station Tiangong is 462 miles.
Angle between the two stations = 109⁰
So, applying the law of cosines as;
c² = a² + b² - 2abcosC
From the picture shown below, a = 323 miles and b = 462 miles
So,
c² = 323² + 462² + 2(323)(462)cos109 = 104329 + 213444 - 298452cos109
cos109 = -0.3256
So,
c² = 414948.9712
<u>c = 644.1653 miles</u>
