Answer:

A Energy must be removed because particles in liquid move more slowly

Explanation:

Gas particles move rapidly colliding with each other, this is as a result of high mobility rate of gases than liquid. Also gases have higher entropy compared to liquid.

The removal of energy from the gas molecules can reduce the rate of the gas particles collision, thereby leading to its transition to liquid which move at lower rate than gas particles.

Correct option is A "Energy must be removed because particles in liquid move more slowly"

A shoe and a shirt are released from the same height. They take different amounts of time to fall to the ground. How can this be

Law Incorporation [45]

The best explanation for the difference in time is: A. The difference in weight doesn't affect the time, but they are affected differently by air resistance.

<h3>What is weight?</h3>

Weight can be defined as the force acting on an object or a physical body due to the effect of gravity. Also, the weight of an object (body) is typically measured in Newton.

<h3>The factors that affect weight.</h3>

Some of the factors that affect the weight that is possessed by an object or a physical body include the following:

Mass

Distance

Air resistance

In conclusion, the weight possessed by the shoe and shirt has no effect on time but would be affected differently by air resistance.

A spherical ball of charged particles has a uniform charge density. In terms of the ball's radius R, at what radial distances in

eimsori [14]

Answer:

Electric field at radius r inside the solid sphere is

Electric field at radius r between inner radius and outer radius of the shell is

E=0 N/C

Explanation:Given

The radius of the solid sphere is

The charge on the solid sphere is

The inner radius of the shell is

The outer radius of the shell is

The total charge on the shell is

PART(A)

The magnitude of electric field at radius r where \\The volumetric charge density of the solid sphere will be

The charge enclosed by the radius r inside the solid sphere is

rho=

According to gauss law

PART(B)

The electric field at radius r where

The shell is conducting so due to induction of charge

The charge induced on the inner surface of the shell is equal in magnitude of the total charge on the solid sphere but polarity will be changed because a conducting shell has no net electric field inside the shell

So,

The charge on the inner surface of the shell is

Due to conservation of the charge on the shell

The charge accumulated on the outer surface of the shell is

The charge enclosed by the radius r where

According to gauss law

An old movie poster used a quote "in space no one can hear you scream!"which of these best explains this quote

soldi70 [24.7K]

I think the complete question is:

An old movie poster used a quote "In space, no one can hear you scream!" Which of these best explains the quote?

A) The quote is incorrect, you can hear sound in outer space.

B) Sound cannot be polarized. So, you cannot hear sound in space.

C) Sound is an electromagnetic wave and needs no medium to travel through.

D) Sound needs a medium for the wave to vibrate and there is nothing in space to vibrate.

Answer:

D) Sound needs a medium for the wave to vibrate and there is nothing in space to vibrate.

Explanation:

There are two types of waves:

Mechanical Waves : These waves requires are medium to travel from one point of space to another point of space. Sound wave is one such example. Since they depend upon medium so speed of travelling also depend upon medium.
Electromagnetic Waves : These type of waves do not require a medium to travel. If medium exists then it will cause some hindrance in there path but still they will travel. For example: Light waves, X-Rays, Microwaves, Infrared waves, Ultraviolet waves etc.

In space no particle exists so no mechanical waves, such as sound, can travel through it but any electromagnetic wave can travel, such as light. That is why when astronauts are in space walk or when they are in outer space then they do not talk rather they use sign language to communicate
