A potter's wheel has the shape of a solid uniform disk of mass 13.0 kg and radius 1.25 m. It spins about an axis perpendicular t

Fittoniya [83]

Answer: $10.82 kg-m^2$

Explanation:

Given

Mass of solid uniform disk $M=13 kg$

radius of disk $r=1.25 m$

mass of lump $m=1.7 kg$

distance of lump from axis $r_0=0.63$

Moment of inertia is the distribution of mass from the axis of rotation

Initial moment of inertia of disk $I_1=\frac{Mr^2}{2}$

$I_1=\frac{13\times 1.25^2}{2}=10.15 kg-m^2$

Final moment of inertia $I_f$ =Moment of inertia of disk+moment of inertia of lump about axis

$I_f=\frac{Mr^2}{2}+mr_0^2$

$I_f=10.15+1.7\times 0.63^2$

$I_f=10.15+0.674$

$I_f=10.82 kg-m^2$

Basile [38]

The geological process that could be responsible for this phenomenon would be the plate tectonics. The plate tectonic theories are believed to be the cause of the landforms forming on the earth's surface. What is described in the questions would be an oceanic ridge which is formed from converging oceanic crusts.

What is one way kinetic energy might be involved in rescue team missions ?

coldgirl [10]

ANSWER: Kinetic Energy is the energy of mass in motion. In a rescue mission, kinetic energy is the most used energy to carry out the rescue operation successfully. The energy of the people involved in the rescue mission is a form of kinetic energy. The machineries involved in the rescue mission like helicopters, submarines, lifeboats are all examples of kinetic energy. To sum up, anything that moves and has a role in rescuing the victims can be termed as the kinetic energy involved in rescue team missions.

nignag [31]

Answer:

Only magnetic field present

Explanation:

Since, the positively charged particle does not speed up or slow down, but it does deflect in the downward direction. This means only magnetic field is present.

This is because electric field changes the velocity and magnetic field changes the direction.

The magnetic force F is given by

F = qvBsinθ

Where, q = charge magnitude, v = velocity of charge, B = strength of magnetic field. and θ =the angle between the directions of v and B.

If two ends A and B are connected through a metallic wire. If electrons flows from point B to point A. What can you say about th

Ivan

Answer:

Point A is at higher potential than point B

Explanation:

Electrons are negatively charged - this means that they are attracted by positive charges and repelled by negative charges.

This also means that they tend to move in a direction opposite to the electric field lines (because electric field lines point away from a positive charge and toward a negative charge). So, they also tend to move from a point at lower potential to a point at higher potential.

In this problem, the electrons flow from point B to point A: therefore, point A must have higher potential than point B.
