When a driver touches a car’s steering wheel on a hot day, heat is transferred to the driver’s hands by ___________?

Alik [6]

The correct answer to this question is : C) Conduction

EXPLANATION:

Before coming into any conclusion, first we have to understand conduction.

Conduction is the mode of transmission of heat in which heat will flow from a body at high temperature to a body at low temperature in contact or from hotter part of the body to its colder part, without any actual transport of particles.

As per the question, the heat is transferred to driver's hand when he touches the steering wheel.

As there is actual contact between hand and steering wheel, the heat transmission will be conduction.

2. Derive a formula for the speed of the wave in terms of the fundamental frequency f1 and the string length L, and enter it bel

grigory [225]

Answer:

The speed of the wave is $f_{1}2L$

Explanation:

Given that,

Frequency = f

String length = l

We need to drive a formula of the speed of the wave

Using formula of fundamental frequency

$f=\dfrac{v}{\lambda}$

We know that,

$\lambda=2L$

$f=\dfrac{v}{2L}$

Where, v = speed of wave

$\lambda$ = wavelength of the wave

f = frequency

The speed of the wave is

$v=f_{1}2L$

Hence, The speed of the wave is $f_{1}2L$

Two light bulbs, A and B, are connected to a 120-V outlet (a constant voltage source). Light bulb A is rated at 60 W and light b

d1i1m1o1n [39]

Answer:

Bulb A has a greater resistance.

Explanation:

Electric power (P) = V²/R

P = V²/R................ Equation 1

Where P = power, V = Voltage, R = Resistance.

Make R the subject of the equation

R = V²/P ................ Equation 2

For Bulb A,

Given: V = 120 V, P = 60 W.

Substitute into equation 2

R = 120²/60

R = 240 Ω

For bulb B

Given: V =120 V, P = 100 W.

Substitute into equation 2

R = 120²/100

R = 14400/100

R = 144 Ω

Hence Bulb A has a greater resistance.
