Which has greater mass of a bowling ball at rest for a rolling basketball which has greater momentum

Physics
1 answer:
IgorLugansk [536]2 years ago
6 0

Answer:

The rolling basketball has greater momentum.

Explanation:

The momentum of an object is defined as the product of mass and velocity.

Given that the bowling mass has a greater mass than the basketball,

The bowling ball is at rest, so the velocity if the ball is zero.

The basketball is rolling, it has some velocity associated with it.

Therefore, the momentum of the bowling ball is zero.

The basketball has some momentum associated with it.

Hence, the rolling basketball has greater momentum.

What is the magnitude of the magnetic dipole moment of the bar magnet
Annette [7]

The magnitude of the magnetic dipole moment of the bar magnet is 1.2 Am²

<h3> Magnetic dipole moment of the bar magnet</h3>

The magnitude of the magnetic dipole moment of the bar magnet at distance from its axis is calculated as follows;

B = \frac{2\mu_0m}{4\pi r^3} \\\\m = \frac{4\pi r^3 B}{2\mu_0}

where;

  • B is magnetic field
  • m is dipole moment
  • μ is permeability of free space

m = (4π x 0.1³ x 2.4 x 10⁻⁴)/(2 x 4π x 10⁻⁷)

m = 1.2 Am²

The complete question is below:

What is the magnitude of the magnetic dipole moment of the bar magnet from 0.1 m of its axis and magnetic field strength of 2.4 x 10⁻⁴ T.

If a ball is given a push so that it has an initial velocity of 5 m/s down a certain inclined plane, then the distance it has ro
iren [92.7K]

Answer:

v= 13 m/s

Explanation:

Velocity is defined as the derivative of displacement with respect to time

v= ds/dt

Known data

s(t) = 5t + 2t²  : distance that the ball has rolled after t seconds

vi= 5 m/s : initial velocity

t= 2 s

Problem develoment

s(t) = 5t + 2t²

v= ds/dt= 5 + 4t : velocity of the ball in function of the time

We replace t =2 s in the equation of velocity

v= 5 + 4(2)

v= 13 m/s : velocity after 2 seconds
