Answer:

The value of the magnetic field inside in the center is 0.89759\times10^{-3}\ T.

Explanation:

Given that,

Number of turns per length = 50

Diameter = 2 mm

Stretched = 10 m

Voltage = 5 V

We need to calculate the resistance

Using formula of

R=\dfrac{\rho l}{A}

R=\dfrac{4\rho l}{\pi d^2}

Put the value into the formula

R=\dfrac{4\times1.1\times10^{-7}\times10}{\pi\times(2\times10^{-3})^2}

R=0.35\ \Omega

We need to calculate the magnetic field

Using formula of magnetic field

B = \mu_{0}nI

B=\mu_{0}n\times\dfrac{V}{R}

B=4\pi\times10^{-7}\times50\times\dfrac{5}{0.35}

B=0.89759\times10^{-3}\ T

Hence, The value of the magnetic field inside in the center is 0.89759\times10^{-3}\ T.

For the most part, this is controlled by how profound the seed is planted, water accessibility, and temperature. At the point when water is abundant, the seed loads with water in a procedure called imbibition.</span>

A transverse wave is traveling through a canal. If the distance between two successive crests is 3.17 m and four crests of the w
Thepotemich [5.8K]

Answer:

a. 0.18Hz

b. 0.56m/s

Explanation:

From the question we can deduct the following parameters

The wavelength, λ is define as the distance between two successful crest or trough and from the question we conclude that wavelength is 3.17m.

Also the period of the wave T can be computed as

T=22.6/4

T=5.65secs.

a. To compute the frequency, recall that frequency, F=1/period.

Hence,

F=1/5.65

F=0.18Hz

b. Next we compute the wave speed.

Wave speed=frequency *wavelength

Wave speed =0.18*3.17

Wave speed =0.56m/s

A firecracker breaks up into three pieces, one of which has a mass of 200 g and flies off along the x-axis with a speed of 82.0
Mamont248 [21]

Answer:

|P_3|=21.242m/s

Explanation:

From the question we are told that:

Mass m=200g=0.2

Speed v=82.0m/s

Mass M_2=300g=0.3kg

Speed V_2=45.0m/s

Generally the equation for Magnitude of the Third piece is mathematically given by

P_1+P_2+P_3=0

|P_3|=|P_1+P_2|

Where

P_1=m_1v_1

P_1=0.2*82

P_1=16.4kgm/s

And

P_2=0.3*45

P_2=13.5kgm/s

Therefore

|P_3|=\sqrt{16.4^2+13.5^2}

|P_3|=21.242m/s
