In fact, there's no list !
Where are the choices ?  What does "the following" mean anyway ? ?

In the USA . . .

-- AM radio broadcasting operates between 550 KHz and 1.7 MHz.

-- FM broadcasting operates between 87.9 MHz and 108.1 MHz.

-- The numbers are slightly different in some other countries.

-- Regarding TV . . . don't ask.  It can get really complicated.

Which equation describes the sum of the two vectors plotted below?

Answers

Final answer:

The sum of two vectors A and B is a resultant vector R, where R = A + B. If vectors A and B are plotted with their tails at the origin and heads at points (x1, y1) and (x2, y2), respectively, the resultant vector R ends at point (x1+x2, y1+y2). This represents the sum of the individual components of vectors A and B.

Explanation:

In vector addition, the equation for the sum of two vectors A and B can be generally represented as R = A + B, where R is the resultant vector. If the vectors are plotted with their tails at the origin and their heads ending at points (x1, y1) for Vector A and (x2, y2) for Vector B, the resultant vector, R, will end at the point (x1+x2, y1+y2). In other words, the components of the resultant vector are simply the sum of the components of the original vectors.

An equinox occurs whena. neither end of Earth’s axis is tilted toward or away from the sun.
b. the north end of Earth’s axis is tilted away from the sun.
c. the north end of Earth’s axis is tilted toward the sun.
d. Earth’s axis is parallel to the sun’s rays.

Answers

Answer: The correct answer is Option a.

Explanation:

An equinox is defined as an event that occurs when Sun's rays fall on the equator at noon and at an angle of 90°.

The axis of rotation of Earth must be perpendicular to the Sun's rays for this event to occur.

If the axis is titled to some angle even, then equinox will not occur.

Hence, the correct answer is Option a.

A! Good luck on your test!

Is there a benefit to cooking in a regular oven compared to a convection oven? Why??

Answers

Yes there is a benefit it is that a regular oven is faster at cooking because it can go to higher tempatures
convectional oven has a lower rate of acceleration, why regular oven has a faster rate.

If a force of 65 N is exerted on a 45 kg sofa and the sofa is moved 6.0 meters, how much work is done in moving the sofa? 17,550 J 171.990 J 390 J none of the above

Answers

Answer:

The answer to your question is:   W = 390 J

Explanation:

Work is the transfer of energy when a body is moved from one place to another.

Data

Force = 65 N

mass = 45 kg

distance = 6 meters

work = ? J

Formula

W = F x d

Process

                   W = 65 N x 6 m

                   W = 390 J

Answer: 390 J

Explain why dogs pant during hot summer days using the concept of evaporation?

Answers

Because dogs have their bodies covered with fur, sweating is less effective. Dogs have sweat glads in places where there is little fur. However this is not enough in some hot days. To keep the body temperature in order dogs have to rely on panting. The interior of mouth and lungs is wet, so breathing quickly speeds up cooling. It acts similarly to wind blowing on sweaty person's skin.

You can try it on your own. When you breathe heavily you will feel coolness :)

In order to evaporate (change state from liquid to gas) heat energy has to be delivered to water. The heat energy is taken from the body of dog, thus cooling it.
