Can a conductor be given limitless charge

Physics
1 answer:
k0ka [10]2 years ago
5 0

Answer:

No

Explanation:

You could try to give it enough to fill all valence electrons in all of the atoms in the conductor, but practically this could not be achieved.

emmainna [20.7K]

Answer:

Explanation:

A ) angular velocity ω = 2π / T

= 2 x 3.14 / 60

= .10467 rad / s

linear velocity v = ω R

=  .10467 x 50

= 5.23 m / s

centripetal force = m v² / R

= mg v² / gR

= 834 x 5.23² / 9.8 x 50

= 46.55 N

B )

apparent weight

= mg - centripetal force

= 834 - 46.55

= 787.45 N

C ) apparent weight

= mg + centripetal force

= 834 + 46.55

= 880.55 N.

D )

For apparent weight to be zero

centripetal force = mg

mg = mv² / R

v² = gR

= 9.8 x 50

= 490

v = 22.13 m /s

time period of revolution

= 2π R /v

2 x 3.14 x 50 / 22.13

= 14.19 s

Consider two antennas separated by 9.00 m that radiate in phase at 120 MHz, as described in Exercise 35.3. A receiver placed 150
alexgriva [62]

Answer:

\phi=4.52 rad

Explanation:

From the question we are told that

Distance b/e antenna's d=9.00m

Frequency of antenna RadiationF_r=120 MHz \approx 120*10^6Hz

Distance from receiver d_r=150m

Intensity of Receiver i= 10

Distance difference of the receiver b/w antenna's (r^2-r^1)=1.8m

Generally the equation for Phase difference \phi is mathematically given by

 \phi=\frac{2\pi}{\frac{c}{f_r}} *(r^2-r^1)

 \phi=\frac{2*\pi}{\frac{3*10^{8}}{120*10^6}} *1.8

 \phi=\frac{4\pi}{5}  *1.8

<h3>  \phi=4.52 rad</h3>

Therefore phase difference f between the two radio waves produced by this path difference is given as

\phi=4.52 rad
