A bar slides vertically between two conducting rails without friction in a magnetic field. The rails are connected via a resisto

Gala2k [10]

Answer:

The energy dissipated is $E = 9.8 J$

Explanation:

From the question we are told that

The distance covered at constant velocity d = 2 m

The velocity is $v = 1.5 \ m/s$

Generally at constant velocity the magnetic force on the bar is mathematically represented as

$F = m * g$

substituting values

$F = 0.5 * 9.8$

$F = 4.9 \ N$

The energy dissipated is mathematically evaluate as

$E = F * d$

substituting the value

$E = 4.9 * 2$

$E = 9.8 J$

Why is it a good idea to touch a metal pole, or similar conductor, before filling up a car with gas?

alexandr1967 [171]

Answer:

because it form static electricity which can cause fire so it is good to touch a metal pole or similar conducter because they will help us to pass the current in the ground

Two identical conducting small spheres are placed with their centers 0.290 m apart. One is given a charge of 12.0 nC and the oth

Solnce55 [7]

Answer:

Force between two identical conducting ball will be $2.65\times 10^{-5}N$

Explanation:

We have given there is two identical conducting small spheres having charge $q_1=12nC=12\times 10^{-9}C$ and $q_2=-21nC=-21\times 10^{-9}C$

Distance between centers of the ball is 0.290 m

So r = 0.290 m

We have to fond the electric force between the balls

According to Coulomb's law force between two charges is given by

$F=\frac{1}{4\pi \epsilon _0}\frac{q_1_2}{r^2}=\frac{Kq_1q_2}{r^2}$

So force $F=\frac{9\times 10^{9}\times 12\times 10^{-9}\times 21\times 10^{-9}}{0.293^2}=2.65\times 10^{-5}N$

So force between two identical conducting ball will be $2.65\times 10^{-5}N$
