Turbine transformer generator⇆
Answer:
Explanation:
r = Radius of atom =
m = Mass of chlorine atom =
= Angular speed =
The moment of inertia of the system is given by
Kinetic energy is given by
The rotational kinetic energy of one molecule of the atom is
Because when people eat food, they are eating it to use its energy. People only need so much energy, so it can be a good idea to see how much energy is in the food you consume. If you eat more energy than you need, it is stored as fat in your body instead.
Answer:
Explanation:
deceleration a
v² = u² - 2as
0 = 7.5² - 2 a x .15
a = 187.5 m / s²
If R be the force exerted by hand
R- mg = ma
R = mg + ma
= .27 ( 9.8 + 187.5 )
= 53.27 N
Work done by hand
= force x displacement
= 53.27 x - .15
= - 8 J
