Answer:

The answer is below!!

Explanation:

Electromagnetic radiation (e.g., radio, microwaves, light) can be modeled as a wave of changing electric and magnetic fields or as particles called photons. The wave model is useful for explaining many features of electro-magnetic radiation, and the particle model explains other features.

Hope I Helped!!

The power rating of a light bulb (such as a 100-W bulb) is the power it dissipates when connected across a 120-V potential diffe
bazaltina [42]

To solve this problem we will apply the concepts related to the calculation of power, from the two electrical forms:

P = VI

P = \frac{V^2}{R}

Here,

V = Voltage

I = Current

R= Resistance

P = Power

PART A)

R = \frac{V^2}{P}

Replacing,

R = \frac{(120V)^2}{150W}

R = 96\Omega

Resistance of bulb is 96\Omega

PART B)

I = \frac{P}{V}

I = \frac{150W}{120V}

I = 1.25A

The bulb will draw 1.25A current

when a man travel from hilly region to terai region what will happen to his weight ? explain with reason.​
Sonbull [250]

Answer:

His weight increases.

Explanation:

  • The weight of the body is the gravitational force acting on the body at that location.
  • The gravitational force is defined as the product of mass  of the body and the acceleration due to gravity.

                                           W = m x g

  • The acceleration due to gravity of earth is high at the surface and decreases with respect to the height from the surface.
  • Hence, a man in the higher altitude regions experience lower weight that in the the lower altitude  regions.

Of the following approximate conversions of celsius into fahrenheit, which is most accurate? a. 24°c almost-equals 75.9°f b. 2°c
Softa [21]

The most accurate among the options is 13°c almost-equals 55.0°f, when you round down 55.4, you get 55.0

Hence, option D) is the most accurate.

<h3>What is Scale of Temperature?</h3>

Scale of temperature is simply a method used in calibrating the physical quantity of temperature in metrology.

Conversion of Celsius into Fahrenheit, Formula is expressed as;

Degree = (0 × 9/5) + 32 = Fahrenheit

First we check each option;

A) 24°c almost-equals 75.9°f

24°C = (24 × 9/5) + 32 = 75.2°F

B) 2°C almost-equals 35.8°f

2°C = (2 × 9/5) + 32 = 35.6°F

C) 34°C almost-equals 92.7°f

34°C = (34 × 9/5) + 32 = 93.2°F

D) 13°c almost-equals 55.0°f

13°C = (13 × 9/5) + 32 = 55.4°F

The most accurate among the options is 13°c almost-equals 55.0°f, when you round down 55.4, you get 55.0

Hence, option D) is the most accurate.

in a certain experiment, a radio transmitter emits sinusoidal electromagnetic waves of frequency 105.0 mhz in opposite direction
Romashka [77]

As a result, the hollow is 10.90 meters long and the distance between the nodal planes is 1.36 meters.

<h3>Explain electromagnetic waves.</h3>

The oscillations between an electric field and a magnetic field produce waves known as electromagnetic waves, or EM waves.

By definition, we understand that the frequency equals,

f = c/λ

where,

λ = wavelength

c= Speed of light

λ = 2L / n

While the wavelength is equal to,

Where,

L = Length

n = Number of antinodes/nodes

PART A) We know that the first component's wavelength is 110 MHz, so

λ = c/ f

λ = 3*10^8 / 11*10^6

λ = 1.36m

Therefore the distance between the nodal planes is 1.36m

PART B) For this part we need to find the Length through the number of nodes (8) and the wavelength, that is,

λ` = 2l /n

L = 8*2.72/ 2

L = 10.90m

Therefore the length of the cavity is 10.90m.
