<h2>Answer:</h2>

<u>Angular velocity of bicycle tire is 15.78 radians per second.</u>

<h3>Explanation:</h3>

Angular velocity is the change in angular speed of an object with respect to time take for change or it is the rate of change of circular motion.

In the given question the circular displacement is 25 rounds around a central point.

The angular displacement is measured in degrees and 1 round is equal to 360 degrees.

25 Rounds = 25 × 360 = 9000 degrees.

Angular velocity = angular displacement /time = 9000/10 = 900 degrees per second.

In SI,angular velocity is represented in radians per second.

So, 1 radian = 57.29 degrees

Angular velocity = 15.78 radians per second

What would be the result of voltage while joining 2 or more different voltages of batteries with parallel ? and explain me what
cupoosta [38]
That's not a good idea. You don't want to connect batteries with different voltages in parallel. What happens is large currents among the batteries themselves, and some of the batteries quickly die.

When the batteries are connected in SERIES, they behave as a single battery whose voltage is the sum of their individual voltages.

What is the formula to find PE and KE ?
Lapatulllka [165]
PE stands for Potential Energy. It is the stored energy in an object due to its position with respect to some reference. It is expressed in Joules.

P.E = m * g * h    OR  P.E. = mgh

m - mass of the body
g - acceleration due to gravity
h - height attained due to the body's displacement.

K.E. stands for Kinetic Energy. It is the energy possessed by a body due to its motion.

K.E = 1/2 mv²    where m = mass of the body; v = velocity with which the body is moving.

I hand you two spheres. They have the same mass, the same radius, and the same exterior surface. I claim one is a solid sphere a
castortr0y [4]

Answer:

Explanation:

Between two spheres of equal masses having equal radius , the one which is hollow will have less moment of inertia and therefore less  radius of gyration ( k )

When they are allowed to roll over an inclined plane , they will have acceleration as follows

a = gsinθ / ( 1 + k²/r²)

For hollow sphere , k is less . therefore denominator is less and acceleration is more.

in other words , hollow sphere will have greater acceleration . So it will reach the bottom of an inclined surface in lesser time if allowed to roll over it .  

This is how we can identify a hollow sphere without breaking it open .
