To solve this problem we will apply the concepts related to the equations of linear motion and angular motion in order to find the radius. Our values are given as,

Then

The relation between the acceleration and the angular velocity and the radius is,

The angular velocity and the lineal velocity can be related as,

The acceleration and the velocity was given, then


Replacing at the first equation we have,



Now using this expression to find the radius we have that



Therefore the correct answer is C.
<span>C option is correct which is big bang theory. According to this theory in start there was no system of earth and all planets were combined. Then there was explosion due to which planets originated and the system of earth and universe started.</span>
An object is moving with constant velocity downwards on a frictionless inclined plane that makes an angle of θ with the horizontal.
1. Which direction does the force of gravity act on the object?
2. Which direction does the normal force act on the object?
Which force is responsible for the object moving down the incline?
Answer:
The answer is below
Explanation:
1. When an object is moving with a constant velocity, the direction the force of gravity act on the object is DIRECTLY DOWN.
2. When an object is moving with a constant velocity, the direction the normal force act on the object "perpendicular to the surface of the plane."
3. When an object is moving with a constant velocity, the force that is responsible for the object moving down the incline is "the component of the gravitational force parallel to the surface of the inclined plane."
Answer:
i honestly don't know
Explanation:
but can you help me with a question
Answer:
8N
Explanation:
the body is subjected to pressure equals to force force inverse to the area of that body given that it is in motion
