Answer:
B. Motion and Friction
Explanation:
The car is moving which is a form of motion and friction because the car is skidding which i think causes friction.
Answer:
The angular velocity of the first object is twice times the angular velocity of the second object.
Explanation:
The expression for the rotational kinetic energy for first object is as follows;
........ (1)
Here, I is the moment of inertia, K is the rotational kinetic energy and is the angular velocity.
The rotational kinetic energy for second object is as follows;
According to given condition, two objects have the same rotational kinetic energy. Object one has twice the moment of inertia than the second.
Suppose, I'=2I.
......... (2)
From (1) and (2),
Therefore, the angular velocity of the first object is twice the angular velocity of the second object.
To solve this problem it is necessary to consider two concepts. The first of these is the flow rate that can be defined as the volumetric quantity that a channel travels in a given time. The flow rate can also be calculated from the Area and speed, that is,
Q = V*A
Where,
A= Cross-sectional Area
V = Velocity
The second concept related to the calculation of this problem is continuity, which is defined as the proportion that exists between the input channel and the output channel. It is understood as well as the geometric section of entry and exit, defined as,
Our values are given as,
Re-arrange the equation to find the first ratio of rates we have:
The second ratio of rates is
C, all cells contain chloroplast, is not part of the cell theory.
