Answer:

RADAR and SONAR. Although they rely on two fundamentally different types of wave transmission, Radio Detection and Ranging (RADAR) and Sound Navigation and Ranging (SONAR) both are remote sensing systems with important military, scientific and commercial applications

Nine-year-old Dakoda realizes that the quantity of water in a glass remains the same, even when the water is poured into a diffe

Archy [21]

Answer:

Conservation

Explanation:

She has observation conservation because If the temperature of the liquids stays constant and the container is insulated and not heat or cool the liquid much would not change the density of the liquid very much so that it's original volume could remain constant.

The interesting thing is not that the child assumes the taller glass holds more liquid but that they fail to understand conservation: the fact that the water from one glass is going to be the same amount after being poured into any other container. It's as if they did not realize the water came from the same glass.

A truck is moving at 2.0 m/s accelerates at a rate of +2.00 m/s2. It does this over a distance of 400.0m. Find the final velocit

otez555 [7]

If <em>v</em> is the truck's final velocity, then

<em>v</em>² - (2.0 m/s)² = 2 * (2.00 m/s²) * (400.0 m)

<em>v</em>² = 1604 m²/s²

<em>v</em> = 40.05 m/s ≈ 40 m/s

Two forces, 80N and 100N acting at an angle of 60 degrees with each other, pull on an object. What single force would replace th

KIM [24]

We use the law of Cosines, resultant force

$F =\sqrt{(F_{1})^2 + (F_{2})^2 + 2 F_{1} F_{2} cos \theta }$

Here, $(F_{1})$ and $(F_{2})$ are forces acting at angle $\theta$ with each other.

Given $F_{1} = 80 N$ , $F_{2} = 100 N$ and $\theta = 60^0$ .

Substituting these given values in above formula we get

$F =\sqrt{(80)^2 + (100)^2 + 2 \times 80 \times 100 \ cos 60^0 } = 156. 20 \ N$ .

Thus, the resultant force is 156 N.

The wavelength of a certain portion of an electromagnetic wave is 314 nm. what is its frequency and classification?

nadezda [96]

The frequency of the electromagnetic wave is 9.55 × 1014 Hz and it is classified as ultraviolet.

<h3>What is meant by electromagnetic waves?</h3>

Electromagnetic waves are forms of energy that are invisible and travel throughout the universe. However, some of the effects of this energy are visible. The light that we see is a component of the electromagnetic spectrum.

Electromagnetic waves, or EM waves, are produced by vibrations between an electric field and a magnetic field. In other words, electromagnetic waves are made up of oscillating magnetic and electric fields.

<h3>How do you calculate the speed of an electromagnetic wave?</h3>

The wavelength and frequency of any periodic wave are used to calculate its speed. v = λf.

In free space, the speed of any electromagnetic wave is equal to the speed of light, c = 3 $*$ 108 m/s.

The frequency of the electromagnetic wave is 9.55 × 1014 Hz and it is classified as ultraviolet.
