Answer:

Explanation:

Microwaves are the electromagnetic waves which are produced by the specially designed vacuum tubes such as magnetrons, gunn diodes, etc.

They are used in the following manner:

1. In Radar systems for the navigation.

2. in microwave ovens for the cooking purposes.

3. In observing the movements of trains on rails.

Answer:

1.) Radar

2.) Cancer Treatment

4.) Cooking

Explanation:

Microwaves are a type of electromagnetic radiations, like radio waves, X-rays, Gamma Rays, ultraviolet radiation. Microwaves has a wide range of applications. It has frequency range 1GHz to 300GHz and has smaller wavelengths. As microwaves do not bend by any obstacles coming in their path, So, it can be used in radar. In cancer treatment, it is used to increase the temperature of tumor cells by high-power microwaves, results in turns cell membrane damage, which in results destruction of cancer cells. In cooking, microwave heat food like the sun rays your face i.e by means of radiation. It increases the energy of molecules inside food, which results in cooking or heating the food.

In a thunderstorm, the thunder occurs at the same time as lightning. Explain how does a person hears the thunder 5s after he see
sergey [27]

Answer:

If you count the number of seconds between the flash of lightning and the sound of thunder, and then divide by 5, you'll get the distance in miles to the lightning: 5 seconds = 1 mile, 15 seconds = 3 miles, 0 seconds = very close. Keep in mind that you should be in a safe place while counting.

Density is the best property to use, as while multiple different metals could create cubes with the same color, mass, or volume, no different metal could create a cube with the same mass and volume.  Density is based on mass and volume, and as a result no two different metals will have the same density.

Monica [59]

Question

A banked highway is designed for traffic moving at v 8 km/h. The radius of the curve = 330 m. 50% Part (a) Write an equation for the tangent of the highway's angle of banking. Give your equation in terms of the radius of curvature r, the intended speed of the turn v, and the acceleration due to gravity g

Part (b) what is the angle of banking of the highway? Give your answer in degrees

Answer:

a. Equation of Tangent

tan(θ) = v²/rg

b. Angle of the banking highway

θ = 0.087°

Explanation:

Given

Radius of the curve = r = 330m

Acceleration of gravity = g = 9.8m/s²

Velocity = v = 8km/h = 8 * 1000/3600

v = 2.22 m/s

a . Write an equation for the tangent of the highway's angle of banking

The Angle is calculated by

tan(θ) = v²/rg

θ = tan-1(v²/rg)

b.

Part (b) what is the angle of banking of the highway? Give your answer in degrees

θ = tan-1(v²/rg)

Substituting the values of v,g and r

θ = tan-1(2.22²/(330 * 9.8)

θ = tan-1(0.001523933209647)

θ = 0.087314873580116°

θ = 0.087°
