Answer:
the final angular speed of the wheel at the bottom is 25.5 rad/s
Explanation:
The computation of the final angular speed of the wheel at the bottom is as follows:
As we know that

Hence, the final angular speed of the wheel at the bottom is 25.5 rad/s
We simply applied the above formula so that the final angular speed could come
Answer:
For macroscopic objects, we use units such as grams and kilograms to state their masses, but. There will not be much error if you estimate the mass of an atom by simply. to what we did for our hypothetical example, but the percentages are different: Add two atomic masses of carbon and six atomic masses of hydrogen:
Explanation:
Answer:
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system.
Explanation:
Equilibrium is defined as a state of balance or a stable situation where opposing forces cancel each other out and where no changes are occurring. ... An example of equilibrium is when hot air and cold air are entering the room at the same time so that the overall temperature of the room does not change at all.
Answer:
The Difference Between the final and initial position of a point trajectory
The speed of the ball is 1.57 m/s
Explanation:
We start by calculating the angular speed of the ball, which is given by

where
T is the period of revolution
For the ball in this problem,
T = 2 s
(since the ball makes 1 revolution every 2 seconds)
So, the angular speed is

Now we can calculate the speed of the ball by using

where
r = 0.5 m is the radius of the circular path
Substituting,
