A net charge is placed on a hollow conducting sphere. How does the net charge distribute itself? A net charge is placed on a hol
makvit [3.9K]

Answer:

The net charge uniformly distributes itself on the sphere's inner and outer surfaces.

Explanation:

In electrostatic condition The charge will be distributed over the surface  of the shell,

The electic field outside the sphere  is like the charge where concentrated in the center of the sphere, inside the sphere the electric field is cero (quivalent to say the potencial is constant, non  electric current flow) If the thickness of the shell is very very thin we just have a charged layer. To keep the above mentioned electrostatic condition the elecrtic field have to be cero in this region  too

Why is it important for DNA to be copied before cell division?
KATRIN_1 [288]
If DNA is improperly copied, the cell will function differently.
This is called a mutation.
Mutated cells do not do the originally intended purpose.

A pilot heads his jet due east. The jet has a speed of 425 mi/h relative to the air. The wind is blowing due north with a speed
Alja [10]

Answer:

(a)Velocity of wind = 35 j

(b)Velocity of jet relative to air = 425 i

(c)True velocity of jet = 425 i + 35 j

(d)True speed of jet = \sqrt{425^{2}+35^{2}} = 426.88 mi/h

    Direction of jet is, ∅ = tan^{-1} \frac{40}{425} = 5.38°

Explanation:

We can represent east direction by i and north direction by j.

The jet has a relative speed of 425 mi/h relative to the air.

The wind is blowing due north with a speed of 35 mi/h = 35 j

425 mi/h is the relative speed with respect to wind that is

Velocity of jet wrt wind= V_{jw} = V_{j}-V_{w}

                               425 i = V_{j} - 35 j

V_{j} = 425 i + 35 j

(a)Velocity of wind = 35 j

(b)Velocity of jet relative to air = 425 i

(c)True velocity of jet = 425 i + 35 j

(d)True speed of jet = \sqrt{425^{2}+35^{2}} = 426.88 mi/h

    Direction of jet is,

     ∅ = tan^{-1} \frac{40}{425} = 5.38°

How does kinect energy affect the stopping distance of a vehicle traveling at 30 mph compared to the same vehicle traveling at 6
mote1985 [20]

If it is the same vehicle, then the 60mph vehicle has more kinetic energy since it is moving faster. Therefore, it requires more energy to stop, and if it is the same car with the same beak system, the braking distance of the 30mph car will be significantly shorter than the 60mph car.

Why would you expect the speed of light to be slightly less in the atmosphere then in a vacuum?
azamat

The speed of light to be slightly less in atmosphere then in vacuum because of absorption and re-emission of light by the atmospheric molecules occurred when light travels through a material

<u>Explanation:</u>

When light passes through atmosphere, it interacts or transmits through the transparent molecules in atmosphere. In this process of transmission through atmosphere, the light will be getting absorbed by them and some will get re-emitted or refracted depending upon wavelength.

But in vacuum the absence of any kind of particles will lead to no interaction and no energy loss, thus the speed of the light will be same in vacuum while due to interactions with molecules of atmosphere, there speed will be slightly less compared to in vacuum.
