Which is NOT a way to stay safe from static electricity?

A circular loop of wire having a radius of 5.58 cm carries a current of 0.230 A. A vector of unit length and parallel to the dip

Sidana [21]

Answer:

see explanation

Explanation:

Given quantities:

radius = r = 0.0558 [m]

current = I = 0.23 [A]

$\vec{B} =$

Now we solve this by obtaining the torque acting on the dipole

$\tau = M \times B$

We obtain the magnetic moment vector M, first, |M| is defined as $M = IA$ , where A is the cross-section area of the loop which is $A = \pi r^2=\pi (0.0558)^2= 0.00978 [m^2]$ then

$|M| = 0.23*0.00978 = 0.00225 [A/m^2]$

now the magnetic moment vector is equal to the magnetic dipole moment vector multiplied the magnitude we just obtained $\vec{M} = M \hat M$

$= 0.00225 *$

Now:

a ) $\tau = M \times B$

b) $U = -M \cdot B$

a) the determinant gives us:

b) the dot product gives = $-1*-7.2*10^{-6} = 7.2*10^{-6}[J]$

Why is nitrogen or helium filled in a filament lamp??

nirvana33 [79]

Argon gas is used in fluorescent and incandescent light bulbs to stop the oxygen in the light bulbs from corroding the hot tungsten filament.The use of argon in lightbulbs prevents the evaporation of the tungsten filaments, which results in increased light bulb life.

Two plastic bowling balls, 1 and 2, are rubbed with cloth until they each carry a uniformly distributed charge of magnitude 0.50

galben [10]

Answer:

The right solution is " $4.5\times 10^{-10} \ Cm$ ".

Explanation:

Given that,

q = 0.50 nC

d = 900 mm

As we know,

⇒ $P=qd$

By putting the values, we get

⇒ $=0.50\times 900$

⇒ $=(0.50\times 10^{-9})\times 0.9$

⇒ $=4.5\times 10^{-10} \ Cm$

What are the uses of nuclear fission or fusion and their benefits

tamaranim1 [39]

Answer: The uses of nuclear fission are nuclear activator utilize for mercantile electric-power alternator throughout the world and it also has powerful starting point for propelling submarines and certainly kinds of surface yacht. And about the fusion benefits, that is that the nuclear fusion has clean vigor, very low power source cost, along with other benefits.

Hopefully this helps you my dear friend! :-)

The spacing between two closely spaced oppositely charged parallel plates is decreased. What happens to the electrostatic potent

erastovalidia [21]

<h2>Electrostatic Potential Decreases</h2>

Explanation:

If the spacing between two closely spaced oppositely charged parallel plates is decreased the electrostatic potential difference between the plates will decrease.

An electrostatic potential that is also referred to as the electric field potential or potential drop is the amount of work required to replace a unit of charge from a reference point to a specific point inside the electric field without any change in acceleration.

Therefore, if the distance will decrease between oppositely charged plates there will be more affinity to attract which will reduce the amount of work done thus decreasing the electric potential

∴ The Correct option is (b)
