Energy is 4 * $10^{5}$ J

The rate of dissipation is 2 * $10^{4}$ W

In the question, it is given that

t = 20 s

R = 400 mm

L = 300 mm

where t, R, and L are time, radius, and length.

For magnetic energy density, the formula is

ηo = Energy / volume

= β^2 / 2 * μ

Now, substituting the values

= $2^{2}$ / 2 * 4 * Π * $10^{-7}$

= 1.59 * $10^{-6}$ J / m^3

Now, energy is

= energy density * volume

= 1.59 * $10^{-6}$ * Π * 0.5 * $0.4^{2}$

= 4 * $10^{5}$ J

The rate of dissipation is

= Energy / time

= 4 * $10^{5}$ / 20

= 2 * $10^{4}$ W

What is the relationship between the valence electrons of an atom and the chemical bonds the atom can form?

stellarik [79]

Answer:

Valence electrons are outer shell electrons with an atom and can participate in the formation of chemical bonds. In single covalent bonds, typically both atoms in the bond contribute one valence electron in order to form a shared pair. The ground state of an atom is the lowest energy state of the atom.

A rock falls from rest off a cliff and hits the ground in 2 seconds. If there is no air resistance, determine the rock's velocit

mihalych1998 [28]

Answer:

19.6m/s

Explanation:

A Rock falling off a cliff can be modeled as an object starting with zero velocity moves with constant acceleration for certain period of time, for such motion following equation of motion can be used.

$v(t) = v_{0} +at$

here in our case $v_{0} =0$ because object starts off from rest and $a = g =9.8m/s^2$ is acceleration because of gravity ( Motion under gravity).

and of course t = 2 second.

Now by substituting all this information in equation of motion we get.

$v(2s) = 0+9.8m/s^2 *2s = 19.6m/s$

that would be the velocity of rock as it would hit the ground.

Note! We have assumed that there is no air resistance.
