Answer:

using more wire loops in the solenoid

Explanation:

Here we know that rate by Faraday's law of electromagnetism

EMF = -\frac{d\phi}{dt}

Now for solenoid we know that

EMF = - L\frac{di}{dt}

now this EMF of induces need to be increased so here we need to increase

1). By increasing the self inductance(L) of the solenoid coil

2). By increasing the rate of change in flux in the coil by moving it fast

Now here inductance is increased by increasing number of turns in the coil

So here correct answer should be related to the more number of loops of the coil which will increase the electric current in the solenoid

The speed of light in a vacuum is approximately 2.99 × 108 m/s, and the speed of light through a piece of glass is approximately
exis [7]

Option (b) is correct.The index of refraction for the glass is 1.52

Explanation:

velocity of light in vacuum= C= 2.99 x 10⁸m/s

Velocity of light in glass = V= 1.97 x 10⁸m/s

The refractive index is given by n=\frac{c}{v}

n= 2.99 x 10⁸/1.97 x 10⁸m/s

n= 1.52

Thus the refractive index of glass is 1.52

A piston-cylinder chamber contains 0.1 m3 of 10 kg R-134a in a saturated liquid-vapor mixture state at 10 °C. It is heated at co
vaieri [72.5K]

Answer:

(A) 10132.5Pa

(B)531kJ of energy

Explanation:

This is an isothermal process. Assuming ideal gas behaviour then the relation P1V1 = P2V2 holds.

Given

m = 10kg = 10000g, V1 = 0.1m³, V2 = 1.0m³

P1 = 101325Pa. M = 102.03g/mol

P2 = P1 × V1 /V2 = 101325 × 0.1 / 1 = 10132.5Pa

(B) Energy is transfered by the r134a in the form of thw work done in in expansion

W = nRTIn(V2/V1)

n = m / M = 10000/102.03 = 98.01mols

W = 98.01 × 8.314 × 283 ×ln(1.0/0.1)

= 531kJ.

Match each type of wave to the way it moves. transverse wave longitudinal wave electromagnetic wave back and forth at right angl
marta [7]

Transverse wave = at right angles to the direction of the motion of the wave

in transverse wave medium particles will move perpendicular to the direction of motion of medium particles

they all are perpendicular to wave always

Longitudinal wave = back and forth in the direction of the motion of the wave

in longitudinal waves medium particles will move in the direction of wave and the motion is always in back and forth type

electromagnetic wave = alternating waves moving at right angles to each other

electromagnetic waves are combination of electric field and magnetic field which oscillates perpendicular to wave as well as they are perpendicular to each other

A moose runs through the woods and covers 825 m North in 118 s. What is the average velocity of the moose?
weqwewe [10]
  • Total displacement=825m
  • Total Time=118s

Average Velocity=Total Displacement/Total Time

\\ \sf\longmapsto Average\: Velocity=\dfrac{825}{118}

\\ \sf\longmapsto Average\:Velocity\approx 8m/s
