$\bf \huge\blue{ANSWER}$

Researchers from the TU Delft and AMOLF have built an efficient and stable photo-electrode that absorbs light and directly decomposes water into hydrogen and oxygen. Silicon wafers are used for the light-absorbing material, so that the system is cheap as well.

A flat, rectangular coil consisting of 60 turns measures 23.0 cmcm by 34.0 cmcm . It is in a uniform, 1.40-TT, magnetic field, w

Travka [436]

Answer:

(a) ΔФ = -0.109W

(b) emf = 28.43V

Explanation:

(a) In order to calculate the magnetic flux you use the following formula:

$\Delta\Phi_B=\Phi-\Phi_o=BAcos(90\°)-BAcos(0\°)$ (1)

B: magnitude of the magnetic field = 1.40T

A: area of the rectangular coil = (0.23m)(0.34m)=0.078m^2

Where it has been taken into account that at the beginning the normal vector to the cross sectional area of the coil, and the magnetic field vector are parallel. When the coil is rotated the vectors are perpendicular.

Then, you obtain:

$\Delta\Phi_B=(1.40T)(0.078m^2)=-0.109W$

The change in the magnetic flux is -0.109 W

(b) During the rotation of the coil the emf induced is given by:

$emf=-N\frac{\Delta \Phi}{\Delta t}$ (2)

N: turns of the coil = 60

ΔФ: change in the magnetic flux = 0.109W

Δt: lapse time of the rotation = 0.230s

You replace the values of the parameters in the equation (2):

$emf=-(60)(\frac{-0.109W}{0.230s})=28.43V$

The induced emf is 28.43V

(c) The induced current in the coil is given by:

$I_{in}=\frac{emf}{R}$ (3)

R: resistance of the coil (it is necessary to have this value)

emf :induced emf = 28.43V

You can describe the of an object by saying it is moving in a straight line or it curved

Serga [27]

My answer -

You can tell the speed of a car at any instant by looking at curved path but it does not move with the average speed of any object moving in a straight line.

P.s

Happy to help you have a AWESOME!!!! day ^-^

At a temperature of 250 K, the gas in a cylinder has a volume of 20 L. If the temperature increased to 260 K, what must the volu

masya89 [10]

Answer:b.20.8L

Explanation:

Since pressure is constant we can use the equation V1/T1 = V2/T2

(20/250)=(x/260)

5200=250x

X=20.8

According to the theory of plate tectonics, what drives the motion of the continents?

Alex

I’m deciding between E or D.. because for E it’s saying it’s changing ocean currents, but I’m thinking does that mean the earths precipitation or their climate. Best go with E, hope this helps
