jack peddles a stationary bicycle. the pedals of the bicycle are attached to a 1000 turn coil of area 0.10 m2. the coil rotates

tatuchka [14]

The maximum voltage generated in the coil is 3.14 V.

According to the question, we are provided that a bicycle turns 1000 of the area of 0.10 m2, where the coil rotates half a revolution per second, which is placed in a uniform magnetic field of 0.01 T.

Therefore, no .of turns the coil took, N = 1000

Area of the coil, A= 0.10 m²

Frequency of the system =0.5 revolutions per second

= 0.5 Hz

The intensity of the Magnetic field , B =0.01 T

So the Equation we refer to for the calculating the desired value

E(ind) = $-db/dt$

= -d(NBAcosωt) / dt

= − NBA d(cosωt) /dt

= NBAωsinωt

if sinωt=1,

maximum E(ind)= NBAω

Since we know, ω=2πf

Therefore, (Eind)max = NBA(2πf)

= (1000)(0.01)(0.1)(2π)(0.5)

(E(ind))max= 3.14v.

the value for the voltage we got is 3.14 V

You could increase the mechanical efficiency of this screw by

MrRa [10]

I can't see the screw (if you'll pardon the expression), so I don't know a thing about it, and can't answer the question. There's no given information in the question.

Bats are capable of navigating using the earth's field-a plus for an animal that may fly great distances from its roost at night

Nataliya [291]

Answer:

The correct magnitude of the coil's magnetic field= =50μT

Explanation :

The magnetic field takes place as a result of movement of charge I e current, can also occurs from magnetised material, magnetic field as a result of charge movement can be deducted using right hand grip rule.

At the equator magnetic field lines are parallel towards the earth's surface and the angle of inclination of the magnetic lines of force at the horizontal position is referred to as the angle of dip at the point.

As the current is produced then the varying magnetic field is opposed ,then there is induced current when the coil is positioned at varying magnetic field.

Given from the question,

angle below horizontal θ=60-degree

The Earth's magnetic field B=50μT

The horizontal magnetic field can be expressed in terms of the formula below;

BH=Bcos⁡θ

B(H) = earth's horizontal component of magnetic field

Ø is the angle between coil's field

B=the magnetic field in Tesla

Then,

BH=50μT×cos60∘

=50μT× 0.5

As the current is passed through the coil to produce a field , when combined with the earth's field, which creates a net field with the same strength and dip angle (60 degrees below horizontal) as the earth's field.

It can be deducted that B has the same magnitude and angle which makes the those vertical component to cancel each other since they are the same.

For the magnetic field to be pointed out at North direction, we can calculate the corrected magnetic field using the formula below

Bc=2BH

Bc=2×50μT× 0.5=50μT

The correct magnitude of the coil's magnetic field= =50μT

What’s a NEURON AND HOW DO THEY WORK? EXPLAIN IN UR OWN WORDS

bulgar [2K]

Answer:

The neuron is the basic working unit of the brain, a specialized cell designed to transmit information to other nerve cells, muscle, or gland cells. Neurons are cells within the nervous system that transmit information to other nerve cells, muscle, or gland cells. Most neurons have a cell body, an axon, and dendrites.

Difference between regular and irregular object.

DaniilM [7]

<h2>Answer:</h2><h2>Regular object</h2>

Those substance which have fixed geometrical shape are called regular object.
For example: books,pencils, basketball etc.

<h2>Irregular object</h2>

Those substance which do not have geometrical shape are called irregular object.
For example: a piece of stone,a broken piece of brick,leaf etc.

Hope this helps....

Good luck on your assignment.....
