Based on your knowledge of the electromagnetic spectrum, why are radio waves considered harmless while ultraviolet waves and x-r
Goryan [66]

The correct answer of this question is : A) Radio waves have longer wavelengths, lower frequency, and lower energy than ultraviolet waves and x-rays.

EXPLANATION :

Before going to answer this question, first we have to know the electromagnetic spectrum.

Electromagnetic spectrum is the arrangement of electromagnetic waves in the ascending order of frequency or descending order of wavelength.

When the waves are arranged in the ascending order of their frequency, then perfect order is given below as such -

Radio wave < Micro wave <  Infrared wave <   Visible light < U.V ray<  X-ray < Gamma ray .

Hence, we see that radio wave has the least frequency, and gamma ray has the most frequency.

We know that wavelength and frequency are inversely are inversely proportional to each other. Hence, radio wave has more wavelength and less frequency.

The wave having more frequency is more energetic. Hence, gamma is more energetic and radio wave is less energetic .

1) 260 km/h

Let's use the following convention:

positive x-direction = east

positive y-direction = north

Here we have to find the north component of the velocity's airplane, which means we have to find its y-component.

We can use the formula:

v_y = v sin \theta

where

v = 750 km/h is the magnitude of the plane's velocity

\theta=20.0^{\circ} is the angle between the direction of the plane and the positive x-axis

Substituting,

v_y = (750)(sin 20)=256.5 km/h \sim 260 km/h

2) 24^{\circ} north of east

In order to find the direction of flight, we have to consider that the vector representing the displacement of the plane is the hypothenuse of a right triangle, of which the displacements along the east and north direction are the sides.

Therefore, we have

v_x = 220 km is the displacement towards east

v_y = 100 km is the displacement towards north

Therefore, the angle that gives the direction is given by

tan \theta = \frac{v_y}{v_x}

And substituting,

\theta =tan^{-1}( \frac{100}{200})=24^{\circ}

and this angle is measured north of east.

Why does conduction occur more slowly in gases than in solids?​
Nataly [62]
Onduction in gas is slower than in liquids and solids because the particles in a gas collide less often. Conduction in metals is faster because the electrons are free to move about
