Answer:
Option D is the correct answer.
Explanation:
Since value of angular acceleration is constant, the body has only centripetal acceleration.
Centripetal acceleration
![a=\frac{v^2}{r}=\frac{(r\omega )^2}{r}=r\omega ^2](https://tex.z-dn.net/?f=a%3D%5Cfrac%7Bv%5E2%7D%7Br%7D%3D%5Cfrac%7B%28r%5Comega%20%29%5E2%7D%7Br%7D%3Dr%5Comega%20%5E2)
We have radius = 7.112 cm = 0.07112 m
Frequency, f = 1975 rpm = 32.92 rps
Angular frequency, ω = 2πf = 2 x π x 32.92 = 206.82 rad/s
Substituting in centripetal acceleration equation,
![a=r\omega ^2=0.07112\times 206.82^2=3042.17m/s^2](https://tex.z-dn.net/?f=a%3Dr%5Comega%20%5E2%3D0.07112%5Ctimes%20206.82%5E2%3D3042.17m%2Fs%5E2)
Option D is the correct answer.
T = 3.5 secs
Velocity (v) = g * t = 10 m/s^2 * 3.5 sec = 35 m/s
Answer:
<em>In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed.</em>

Answer:
Nitrogen, Oxygen, Argon.
Explanation:
The three (3) most abundant gases in the dry atmosphere are"
- Nitrogen
- Oxygen
- Argon
These are not the only components of dry air. Dry atmosphere is made up of:
- 78.09% Nitrogen;
- 20.95% Oxygen;
- 0.93% Argon;
- 0.04% Carbon dioxide;
- Other gases
Static friction is what you are looking for.
Kinetic friction is the force exerted on an already moving object, slowing it down.
