Answer:
God is omnipresent.
Explanation:
This means God is everywhere and He works where ever we are in the world
To solve this problem it is necessary to apply the concepts related to the centripetal Force, the Force of the weight produced by the gravity of the star and the definition of the velocity as a function of time (period)
In other words, for balance to exist, the force acting on the body (weight) must be equal to the centripetal force that attracts it in motion. That is to say
The value of the given period is 110min or 6600s.
At the same time we know that the speed of a body depending on its period (simple harmonic movement) is subject to
Finally, replacing this value in the event of gravity we have to
Answer:
The speed is
Explanation:
From the question we are told that
The mass of the first skater is
The final speed of the first skater is
The mass of the second skater is
According to the principle of linear momentum conservation
Here
Since they they started from a stationary position
So
While
substituting values
So
=>
Answer:
A.
Explanation:
To solve this problem it is necessary to take into account the concepts related to angular velocity and centripetal acceleration,
from the cinematic equations of motion we know that
where,
V = Tangential Velocity
r = radius
Angular velocity
While the centripetal acceleration is given by
The displacement of the object is based on gravitational acceleration, so
a = g = 9.8 and the radius would be
Reemplazando:
Therefore the answer is A.
