The main activity that is involved in studying of physics is the study of natural laws. The study of physics has to do with many aspects of the universe. Physics majorly looks into the natural laws that operate in the universe and describe how they affect matter in relation to time.
Answer:
I. 0 m/s
II. 20 m/s
III. Part BC
Explanation:
I. Determination of the initial velocity.
From the diagram given above,
The motion of the car starts from the origin. This implies that the car start from rest and as such, the initial velocity of the car is 0 m/s
II. Determination of the maximum velocity attained.
From the diagram given above, we can see clearly that the maximum velocity is 20 m/s.
III. Determination of the part of the graph that represents zero acceleration.
It important that we know the meaning of zero acceleration.
Zero acceleration simply means the car is not accelerating. This can only be true when the car is moving with a constant velocity.
From the graph given above, the car has a constant velocity between B and C.
Therefore, part BC illustrates zero acceleration.
I believe the correct answer would be kimberlite. Diamonds are usually found in pipes 50 to 200 m across made of kimberlite. It is an igneous rock that is known to contain traces of diamonds. It is named base on the town where it was discovered which is Kimberley, South Africa.
Answer:
a
b
Explanation:
From the question we are told that
The radius of the flywheel is 
The mass of the flywheel is 
The rotational speed of the flywheel is 
The power supplied by the motor is 
Generally the moment of inertia of the flywheel is mathematically represented as
substituting values
The kinetic energy that is been stored is
substituting values
Generally power is mathematically represented as
=> 
substituting the value
As you gave no pic I took them on one lined
- F_1=3N
- F_2=10N
- F_3=3root 3 N
- F_4=6N
