A coil of 40 turns is wrapped around a long solenoid of cross-sectional area 7.5×10−3m2. The solenoid is 0.50 m long and has 500

defon

To solve this problem it is necessary to apply the concepts related to mutual inductance in a solenoid.

This definition is described in the following equation as,

$M = \frac{\mu_0 N_1 N_2A_1}{l_1}$

Where,

$\mu =$ permeability of free space

$N_1 =$ Number of turns in solenoid 1

$N_2 =$ Number of turns in solenoid 2

$A_1=$ Cross sectional area of solenoid

l = Length of the solenoid

Part A )

Our values are given as,

$\mu_0 = 4\pi *10^{-7}H/m$

$N_1 = 500$

$N_2 = 40$

$A = 7.5*10^{-4}m^2$

$l = 0.5m$

Substituting,

$M = \frac{\mu_0 N_1 N_2A_2}{l_1}$

$M = \frac{(4\pi *10^{-7})(500)(40)(7.5*10^{-4})}{0.5}$

$M = 3.77*10^{-4}H$

PART B) Considering that many of the variables remain unchanged in the second solenoid, such as the increase in the radius or magnetic field, we can conclude that mutual inducantia will appear the same.

If a car accelerates from 0 to 10 m/s in 4 seconds, and the mass of the car is 1500 kg. What force is created by the car?

Minchanka [31]

Answer:

PLS MARK BRAINLIEST

Explanation:

f=m (v- u)/t

u=0m/s

v=10m/s

t=4 secs

m=1500kg

f=1500(10-0)/4

f=3750N

Wewaii [24]

Answer:

the maximum force will be equal to 134.84 N

Explanation:

We have given mass m = 43 kg

Coefficient of static friction $\mu _s=0.32$

Acceleration due to gravity $g=9.8m.sec^2$

We have to find the maximum force which , when applied there is no movement of crates

This maximum force will be equal to frictional force

Frictional force is given by $f=\mu mg=0.32\times 43\times 9.8=134.84N$

So the maximum force will be equal to 134.84 N
