Aphysicist is constructing a solenoid. she has a roll of insulated copper wire and a power supply. she winds a single layer of the wire on a tube with a diameter of dsolenoid = 10.0 cm. the resulting solenoid is ℓ = 60.0 cm long, and the wire has a diameter of dwire = 0.100 cm. assume the insulation is very thin, and adjacent turns of the wire are in contact. what power (in w) must be delivered to the solenoid if it is to produce a field of 6.40 mt at its center? (the resistivity of copper is 1.70 ✕ 10−8 ω · m.)

P =105.44 W

Explanation:

Given that

D= 10 cm ,L= 60 cm

d= 0.1 cm ,B= 6.4 mT

ρ= 1.7 x 10⁻⁸ Ω · m

The number of turns N

N= L/d

N= 60/0.1 = 600 turns

Length of wire

Lc= πDN

Lc= 3.14 x 0.1 x 600

Lc=188.4 m

The magnetic filed given as

Now by putting the values

I=5.09 A

The resistance R given as

R=4.07 Ω

Power P

p =I²R

P= 5.09² x 4.07 W

P =105.44 W

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
