A ten loop coil of area 0.23 m2 is in a 0.047 T uniform magnetic field oriented so that the maximum flux goes through the coil.
andrezito [222]

Answer:

Explanation:

From the question we are told that:

Number of turns N=10

Area a=0.23m^2

Magnetic field B=0.947T

Generally the equation for maximum flux is mathematically given by

 \phi=NBa

 \phi=10*0.047*0.23

 \phi=0.1081wbi

Therefore induced emf

 e= \frac{d\phi}{dt}

Since

 t=0

Therefore

 e=0

What is the energy of a single photon of infrared light with a wavelength of 1.00 µm? 1 µm = 10^-6m
notka56 [123]

Answer:

Energy is found as:

E = 1.987·10⁻¹⁹ J

Explanation:

Energy of a single photon of infrared light can be found by using the following formula:

E=hf

where

E = in Joules

h = Planck's constant = 6.627×10 ⁻³⁴ J

f = frequency in hertz

It can also be written as:

E = \frac{hc}{\lambda}

where

c = 2.998×10⁸ ms⁻¹

λ = wavelength

Wavelength is given in the question which is:

λ = 1×10⁻⁶m

Substitute all the values in the Energy formula

E = \frac{hc}{\lambda}\\E = \frac{(6.627\cdot10^{-34})(2.998\cdot10^8)}{1\cdot10^{-6}}\\E = 1.987\cdot10^{-19}J

8.92 A 45.0 kg woman stands up in a 60.0 kg canoe 5.00 m long. She walks from a point 1.00 m from one end to a point I .00 m fro
omeli [17]

The distance that the canoe moves in this process is 1.29 meters.

We first have to find the center of mass

X = \frac{MsXs+McXc}{Mw+Mc} \\\\

Where

Ms = Woman's mass = 45

Mc = Canoe's mass = 60kg

Xs = position from left= 1 cm

Xc = position from left end of canoe's mass = 2.5cm

When we put these values into the equation we have:

X=\frac{45*1+60*2.5}{45+60} \\\\= 1.857\\

The center of gravity lies at the center of this boat. Therefore,

Xc = \frac{L}{2} \\\\L = 5 m long\\\\\frac{5}{2} =2.5

5.00 - 1. 00 = 4 meters

\frac{45*4+60*2.5}{45+60} = 3.14meters\\\\

To get the distance that is moved by this canoe

distance = 3.143-1.857

= 1.286

≈ 1.29 meters

The distance that the canoe moves in this process is 1.29 meters.
