Answer:
0.8024
Explanation:
From the given question; we can say that the angular momentum of the system is conserved if the net torque is is zero.
So; 
At the closest distance ; the friction is :
According to Newton's Law:
F = ma
F = mrω²
From conservation of momentum:
However ; since the static friction is producing the centripetal force :
The coefficient of static friction between the bottoms of your feet and the surface of the turntable can now be calculated by using the formula :
= 
= ![[\frac{1200+(73(6)^2)}{((1200)+(73)(3)^2)} ]^2*[\frac{(\frac{\pi}{4})^2(3)} {9.8}]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B1200%2B%2873%286%29%5E2%29%7D%7B%28%281200%29%2B%2873%29%283%29%5E2%29%7D%20%5D%5E2%2A%5B%5Cfrac%7B%28%5Cfrac%7B%5Cpi%7D%7B4%7D%29%5E2%283%29%7D%20%7B9.8%7D%5D)
= 0.8024
Answer:
D) it explodes as a super nova
Explanation:
The major source of cloud development is the water vapours from the surface of huge reservoirs like lakes. Vapours do not form when the water is cold. Water evaporates only when the surfave of the water is hot. And the vapours go into the atmosphere and condense to form clouds. Without vapours,there will be no clouds.
Answer:
a - 3
, b - 2
, c-- 2
, d - 1
Explanation:
In this exercise we must relate the different physical processes with the force responsible for the process:
a. Neutron decay
the disintegration of the neutral is an example of the weak interaction
a - 3
b. The Earth pulls the Moon.
In this case as the two bodies and with great mass, the interaction is the gravitational interaction
b - 2
c. gravitational interaction
c-- 2
d. Protons repel other protons in the nucleus.
Since the two particles have a positive charge, the interaction is electromagnetic
d - 1
missing the case of the strong interaction that is responsible for the attraction of proton proton and proton neutron within the nucleus
