The mass of the flywheel is 
The rotational speed of the flywheel is 
The power supplied by the motor is 
Generally the moment of inertia of the flywheel is mathematically represented as
substituting values
The kinetic energy that is been stored is
substituting values
Generally power is mathematically represented as
=> 
substituting the value
Answer:
6.32 m/s 18.43° northeast
Explanation:
We express the velocity of hawk as:
We consider positive x towards east and positive y due north. So the magnitude is simply the square root of the square components:
![|v_{hawk}|=\sqrt[]{6^2+2^2}=\sqrt{40}](https://tex.z-dn.net/?f=%7Cv_%7Bhawk%7D%7C%3D%5Csqrt%5B%5D%7B6%5E2%2B2%5E2%7D%3D%5Csqrt%7B40%7D)
≈
And the angle with respect to the east should be with:
This is a way of measuring how much gravity there is. The formula is: weight/mass = gravitational field strength.
Gravitational field strength = Weight/mass unit is N/kg
Weight = mass x gravitational field strength unit is N
On Earth the gravitational field strength is 10 N/kg. Other planets have different gravitational field strengths. The Moon has a gravitational field strength of 1.6 N/kg. You might have seen films of astronauts leaping high on the moon.
Here on Earth, if I jump I am pulled back to ground by gravity. What is my weight? My mass is 80kg and if we multiply by gravitational field strength (10N/kg) - my weight is 800N. Now if I go to the moon, my mass will be the same, 80kg. We multiply that by the moon's gravitational field strength, which is 1.6 N/ kg. That means my weight on the moon is 128N. So I have different weights on the Earth and on the Moon. That's why astronauts can jump high into the air on the moon - they're lighter up there.
Jupiter is a very large planet with strong gravitational field strength of 25 N/ kg. My body is 80kg. If I go to Jupiter my weight is going to be 25 x 80 = 2,000 N. That means I wouldn't be able to get off the ground or stand up straight! I would probably be lying down all the time there. So weight varies depending on which planet you are on. You can find out more yourself by looking up tables of weight on different planets.
Answer:
2) Denotative meaning of a word or Denotation.
3) Connotative meaning of a word or Connotation.
4) Ethics and Culture.
Explanation:
2) Which meaning of a word refers to exactly what it is?
The denotative meaning of a word represents the explicit or the exact meaning of that word. Also called the denotation of the word.
3) Which meaning of a word includes what the word may represent?
The Connotative meaningof a word means something suggested or implied by a word. Also called the Connotation of the word.
4) What is the term used for society's tried and true rules that guide life?
Ethics refer to the rules and standards that guide the conduct of individuals; especially members of a societal body.
Culture is the total way of life of a society.
Hence, ethics amd culture both serve as the society's tried and tested rules that guide life.
Hope this Helps!!!
