Answer:

The positive ball would go first to the negatively charged plate.

Explanation:

After which, it would hold a more negative charge. Due to the negative charge, it would travel towards the positive plate. Thereby, it would transfer negative electrons to the positive plate once more. In doing so, it would transfer positive protons to the negative plate. After which, it would hold more  negative electrons and be drawn towards the positive plate once more. The Process would continue until the once-positive and once-negative became neutral ( and were discharged.) Additionally, the ball hanging on the insulator thread would also be neutral and discharged.

A student lifts a 50 pound (lb) ball 4 feet (ft) in 5 seconds (s). How many joules of work has the student completed?
Elis [28]

           Work = (weight) x (distance)

  Work = (50 lb) x (1 kg / 2.20462 lb) x (9.81 newton/kg)

                           x (4 feet) x (1 meter / 3.28084 feet)

           = (50 x 9.81 x 4) / (2.20462 x 3.28084)  newton-meter

           =        271.3 joules .

We don't need to know how long the lift took, unless we
want to know how much power he was able to deliver.

                   Power = (work) / (time)    

                               = (271.3 joule) / (5 sec)  =  54.3 watts .
________________________________________

The easy way:

         Work = (weight) x (distance)

                
  = (50 pounds) x (4 feet)  =  200 foot-pounds

Look up (online) how many joules there are in 1 foot-pound.

There are  1.356 joules in 1 foot-pound.

So  200 foot-pounds = (200 x 1.356) = 271.2 joules.

That's the easy way.

A drum rotates around its central axis at an angular velocity of 19.8 rad/s. If the drum then slows at a constant rate of 3.02 r
Debora [2.8K]

a) Time taken =6.39 s

b) Angle of rotation while coming to rest = 188.17 rad

<u>Explanation:</u>

Initial angular velocity of the drum \omega_{0} = 19.8 rad/s^{2}

Angular acceleration of the drum \alpha = -3.02 rad/s^{2}

a.) We know that

\omega =\omega_{0} + \alpha  t

0 =  19.8 - 3.02 t

t = \frac{19.8}{3.02}

t = 6.39s

b.) we know that

\theta = \omega_{0} t + \frac{1}{2} \alpha   t^{2}

\theta = 19.8 \times 6.39 + \frac{1}{2} \times 3.02 \times 6.39^{2}

\theta =188.17 rad

An infinite plane of charge has surface charge density 7.2 μC/m^2. How far apart are the equipotential surfaces whose potential
Rina8888 [55]

Answer:

so the distance between two points are

d = 0.246 \times 10^{-3} m

Explanation:

Surface charge density of the charged plane is given as

\sigma = 7.2 \mu C/m^2

now we have electric field due to charged planed is given as

E = \frac{\sigma}{2\epsilon_0}

now we have

E = \frac{7.2 \times 10^{-6}}{2(8.85 \times 10^{-12})}

E = 4.07 \times 10^5 N/C

now for the potential difference of 100 Volts we can have the relation as

E.d = \Delta V

4.07 \times 10^5 (d) = 100

d = \frac{100}{4.07 \times 10^5}

d = 0.246 \times 10^{-3} m
