Answer:
The angle is 
Explanation:
From the question we are told that
The mass is 
The radius is 
The speed is 
According to the law of energy conservation
The potential energy of the mass at the top is equal to the kinetic energy at the bottom i.e
=> 
Here h is the vertical distance traveled by the mass which is also mathematically represented as
So
![\theta = sin ^{-1} [ \frac{1}{2* g* r } * v^2]](https://tex.z-dn.net/?f=%5Ctheta%20%20%20%3D%20sin%20%5E%7B-1%7D%20%5B%20%5Cfrac%7B1%7D%7B2%2A%20g%2A%20r%20%7D%20%2A%20%20v%5E2%5D)
substituting values
![\theta = sin ^{-1} [ \frac{1}{2* 9.8* 1.1 } * (3.57)^2]](https://tex.z-dn.net/?f=%5Ctheta%20%20%20%3D%20sin%20%5E%7B-1%7D%20%5B%20%5Cfrac%7B1%7D%7B2%2A%209.8%2A%201.1%20%7D%20%2A%20%20%283.57%29%5E2%5D)
Answer:
12 m
Explanation:
The object is in uniformly accelerated motion, so the distance covered can be found using the following suvat equation:
where
s is the distance
u is the initial velocity
t is the time
a is the acceleration
For this problem,
and
u = 0, since we are considering the first second of motion
So, substituting t = 1 s, we find
Have in mind: Energy is always conserved and, (...) be transferred between objects or systems, from one form to another.
Hence, the true relation is C, when a system gains kinetic energy, it loses potential energy.
Think about this,
K + P = constant
If K increases, then P need to decreases to holds the above relation.
One of the two daughter cells wouldn't have a nucleus, which would result in the death of that cell, if not both. Hope this helps! ❤️
