Answer:

There can be no net charge inside the conductor, and the charge must reside uniformly on the outside surface of the sphere.

  • what is conducting shell?

When there is charge present only on the surface, the sphere is called conducting shell.

Here, A conducting shell has total extra charge.

Gauss’s Law is defined as:

  • The flux through a closed surface is equal to the total charge enclosed within the closed surface divided by the permittivity of vacuum.

The electric field of conducting sphere of uniform charge:

  • E = k*Q/r^2

From the Gauss law we can say that,  

There can be no net charge inside the conductor, and the charge must reside uniformly on the outside surface of the sphere.

Since the moon has less mass then the earth what happens to objects on the moon
marshall27 [118]

A) They move slower


Gravity force is determined by mass and the size of the moon. Since the mass of the moon is significantly lower than the mass of Earth, it will pull objects slower. The only object that would fall faster on the moon than on earth is a sheet of paper since there is much, much less air resistance to affect its terminal velocity the way it does on the earth.

Why is Einstein's description of gravity called a theory, while Newton's is a law?
Ludmilka [50]
Albert Einstein came up with the theory of general relativity to explain the law of gravity, whilst Newton's three laws of gravity is universal. To understand this further, it's best to understand it in scientific terms.

The weird thing about science is that words that are used in a colloquial sense may have a completely opposite definition in scientific terms.

A law in science is a constant and invariable statement that is universal. Wherever you may be in the universe, Newton's three laws of gravity will always be applied.

The word "theory" doesn't imply conjecture or an idea someone made up after a night of drinking. In science, a theory is the highest level of certainty behind mathematical proof -- which isn't even a part of science, obviously. A theory has to be substantiated by all available evidence and contradicted by none. All theories also have to have to be falsifiable. For this reason, theories can never be proven. Einstein's theory of general relativity has great predictive power, but in some cases, the predictions aren't always constant. Theories are often revised to fit new available evidence.

g PRACTICE ANOTHER Two trains approach each other on separate but adjacent tracks. Train 1 is traveling at a speed of 30.3 m/s a
e-lub [12.9K]

Answer:

  f'= 607.8 Hz

Explanation:

This is a Doppler effect exercise due to the relative velocity of the sound source and the observer.

By the time the source and the observer are getting closer the expression is

         f ’=f_o \ \frac{ v+ v_o}{v - v_s}

where vs is the speed of the source, vo is the speed of the observer, if the bodies move away the signs are exchanged

in this case, train 1 emits sound, so its speed is v_s = 30.3 m / s and train 2 is the receiver of the sound v₀ = 22.5 m / s

let's calculate

          f ’= 520 \ ( \frac{343 + 22.5}{343 - 30.3} )520 (343+ 22.5 / 343 - 30.3)

          f'= 607.8 Hz

a sprinter with a mass of 80kg accelerates uniformly from 0 m/s to 9 m/s in 3 s. a.)what is the runners acceleration? b.) what i
Katyanochek1 [597]
Part A: 
Acceleration can be calculated by dividing the difference of the initial and final velocities by the given time. That is,
             a = (Vf - Vi) / t
where a is acceleration,
Vf is final velocity,
Vi is initial velocity, and
t is time

Substituting,
            a = (9 m/s - 0 m/s) / 3 s = 3 m/s²
<em>ANSWER: 3 m/s²</em>

Part B: 
From Newton's second law of motion, the net force is equal to the product of the mass and acceleration,
               F = m x a
where F is force,
m is mass, and 
a is acceleration

Substituting,
              F = (80 kg) x (3 m/s²) = 240 kg m/s² = 240 N

<em>ANSWER: 240 N </em>

Part C: 
The distance that the sprinter travel is calculated through the equation,
         d = V₀t + 0.5at²

Substituting,
            d = (0 m/s)(3 s) + 0.5(3 m/s²)(3 s)²
             d = 13.5 m

<em>ANSWER: d = 13.5 m</em>
