HELP PLEASE

Physics
1 answer:
lisov135 [29]4 years ago
8 0

Answer: Hope this Helps...

Explanation:

Force may be defined as the cause of motion and deformation. When a force is applied to an object, the object either moves or changes shape or both. In most cases, it is not possible to detect the deformation by naked eyes at the molecular or atomic level. Deformation occurs no matter how small.

For example, a car moving along a straight and horizontal highway, experiences an engine force Fe, while being opposed by an overall frictional force, Ff ( road friction as well as air resistance). If the car is moving to the right and to the right is taken to be the positive direction, then Fe acts to the right and Ff acts to the left. The net force is ΣF = Fe - Ff .

Slav-nsk [51]

(B) 1.00 m

Explanation:

Since the meter stick is traveling with Jill, it will have the same speed as she does so relative to Jill, the meter stick is stationary so its length remains 1.00 m as measured by her.

How does the see temperature affect hurricane formation?
insens350 [35]
The higher the sea surface temperature, the faster the warm, moist air rises into the atmosphere. This updraft creates a donut shaped vortex that is rising in the middle and going downward on the sides. The more moisture in the air (humidity), the stronger the vortex will become as the moisture rises through convective currents, cools, and falls through convective currents. This eventually causes rotation of the storm mass and you get a tropical cyclone. So, the high sea surface temperatures and humidity are actually the engine that forms a hurricane and causes it to increase in strength.

High level horizontal winds can prevent a hurricane from forming. These are called shear winds and they literally blow the top of the cyclone off, preventing it from forming properly.

Help me with the following problem
Snezhnost [94]

The electric field at arbitrary point outside the sphere is determined as the E = σr³/k.

<h3>Electric field determined from Gauss law</h3>

The electric field of the surface is determined from Gauss law as shown below;

E ∫ds = Q/ε

E (4πr²) = Q/ε

E = Q/4πεr² . r

E = \frac{Q R}{4\pi \varepsilon r^3}

<h3>Electric field outside the sphere with dielectric with polarization</h3>

P = \frac{\sigma}{E} \\\\E = \frac{\sigma}{P}

E = \frac{\sigma}{k/r^3} \\\\E = \frac{\sigma r^3}{k}

where;

  • σ is dipole moment of atom of the metal
  • k is dielectric constant

Thus, the electric field at arbitrary point outside the sphere is determined as the E = σr³/k.

The complete question:

A metal sphere of radius R carries a total charge Q. outside the sphere is a dielectric with polarization p(f) k/r^3er. Determine the electric field at arbitrary point outside the sphere.
