Answer:

im confused

Explanation:

Answer:

A. Constructive

B. Destructive

C. Destructive

D. Constructive

Explanation:

Constructive interference takes place at locations along the path of two superposed waves where the waves are in phase such that a high or low point of one of the waves corresponds with a high or low point of the other wave which gives a resulting wave amplitude which is the sum of the amplitudes of the individual waves

Destructive interference takes place at locations along the path of two superposed waves where one wave is out of phase with the other wave such that a high or low point of one of the waves coincides with a low or high point of the other wave respectively thereby cancelling the effect of the other wave and giving a resulting wave that has an amplitude which is the difference in the amplitudes of the individual waves

Therefore;

At point A, the peak of each wave partially coincides resulting in constructive interference

At point B, the peak of the blue wave and the trough of the red wave partially coincides resulting in destructive interference

At point C, the through of the blue wave and the peak of the back wave partially coincides resulting in destructive interference

At point D, the trough of each wave partially coincides resulting in constructive interference.

Answer:

C. Data is analyzed on a computer

Explanation:

Computers can analyze electrical signals, not radio signals. This means that the radio waves need to be converted to electrical signals to help the computer analyze the data.

Answer:

Explanation:

Although we do have an equation for this in terms of one-dimensional motion, it's easy enough just to use the mathematical definition of acceleration:

[tex]a=\frac{v_f-v_0}{t}[/tex]  which says, in words, the acceleration of an object is equal to the objects final velocity minus its initial velocity, divided by the change in time. Since everything is given in m and s, our answer will be in m/s/s:

[tex]a=\frac{16.0-4.0}{4.0}[/tex] and

[tex]a=\frac{12.0}{4.0}[/tex] so

a = 3.0 m/s/s

Exothermic because energy is a product

Explanation:

Since energy is a product, heat was released, meaning that the reaction is exothermic.

Answer:

The atom consists of a tiny nucleus surrounded by moving electrons. The nucleus contains protons, which have a positive charge equal in magnitude to the electron's negative charge. The nucleus may also contain neutrons, which have virtually the same mass but no charge.

Explanation: Use of these terms stretches back to World War I. One American field order from September 1918 noted, “The First Army will attack at H-Hour on D-Day with the object of forcing the evacuation of the St. Mihiel salient.” Other nations had their own shorthand. In World War I, the French used the code date “le Jour J,” while the British called their operation start days “Z-Day” and “Zero Hour.”

You and your younger sister (who weighs half as much you do) are at a skating rink. You and your sister's both move backward but your sister accelerates at a greater rate.

The time rate of change of velocity with time.

As both are holding each other, they will be pushed backwards because the skating they wear makes them to move backwards. The equal and opposite force is applied on each other.

The force F =mass x acceleration.

The lesser mass greater will be the acceleration. Your sister with half weight of yours will accelerate more.

Thus, you and your sister's both move backward but your sister accelerates at a greater rate.

Answer:

gravity

Explanation:

its hard to explain its one of the resons we do gravity assists for space probes and such the meteor will catch earths gravity and be pulled in by it if you look at sednas orbit as it gets closer to the sun it speeds up.

The force that causes the meteor's speed to increase as it gets closer to Earth is the gravitational force of earth.

Gravity is defined as the force by which a planet attracts another body towards its center.

Here,

The meteor was moving through space and the speed of the meteor started increasing as it moves closer to the earth.

This is because of the gravitational force of earth that is being exerted on the meteor. Gravitational force of earth is defined as the force of attraction that the earth exerts on another body in its gravitational field and draws them towards the center of the earth.

As the meteor moves towards the earth's , it gets accelerated by the earth's gravitational field such that the speed of the meteor increases and thus it attains more kinetic energy. As a result, the meteor moves faster when it gets closer to earth. This is because of the force of gravity of the earth.

Hence,

The force that causes the meteor's speed to increase as it gets closer to Earth is the gravitational force of earth.

Answer:

248 minutes

Explanation:

6200/25=248

This means there is 248 25s in 6200

which means it will take 248 minutes to travel through the river

Also here's a neat trick:

The units for speed is meters/minute

The units for distance is meters

Dividing distance by speed will cancel out the meters and leave only the speed.

Answer:

Λ = 2 t

Explanation:

This is a problem is interference by reflection, where it is requested not to take into account the changes of phase and change in the wavelength within the film

                   λₙ = λ₀ / n

When the wave enters the film, it must reach the end of the film, be reflected and reach the initial surface, therefore the total length is

                d = 2 t

where t is the thickness of the film, because the film is perpendicular to the surface

therefore the difference in optical path between the reflected ray on the surface and the end film is

                  Λ = 2 t

The statement as aurora australis known as northern lights is incorrect. As the designation of aurora australis is for the southern lights i.e. which occur in the southern hemisphere.

Explanation:

Aurora or natural lights is a phenomenon that occurs at the poles of the Earth due to interaction between the Earth's magnetic field and cosmic rays. This interaction results in the beautiful display of colors on both poles. These are named, aurora borealis or aurora australis depending on their geographical location. If they occur on the northern pole they are termed as aurora borealis while those occurring on the southern pole are named aurora australis.

Answer:

C. The aurora australis is known as the northern lights.
