Answer:
The magnitude of gravitational force between two masses is 
.
Explanation:
Given that,
Mass of first lead ball, 
Mass of the other lead ball, 
The center of a large ball is separated by 0.057 m from the center of a small ball, r = 0.057 m
We need to find the magnitude of the gravitational force between the masses. It is given by the formula of the gravitational force. It is given by :
So, the magnitude of gravitational force between two masses is . Hence, this is the required solution.
To develop the problem it is necessary to apply the equations related to the moment of inertia.
The given values can be defined as,
According to the definition of the moment of inertia applied to the exercise we can arrive at the equation that,
Where n is the number of spokes necessary to construct the wheel.
Replacing the values at the general equation we have,
Solving for n,
Therefore the number of spokes necessary to construct the wheel is 36
PART B) The mass of the wheel is given by the sum of all masses and the total spokes, then
Therefore the mass of the wheel must be of 1.36Kg
Answer:
C is the right answer.
Body massager uses electrical energy to move back and forth. In this sense, a motor is being used for the operation
When two forces act in the same direction, they add together. ... Equal forces acting in opposite directions are called balanced forces. Balanced forces acting on an object will not change the object's motion. When you add equal forces in opposite direction, the net force is zero.
Answer:
The velocity of the ball is 5 m/s to the left.
Explanation:
-25kg*m/s divided by 5 kg gives
speed of -5 m/s
The velocity of the ball is 5 m/s to the left.
