Answer:

$7.95

Explanation:

$5.75 cost per bag ÷ 47 apples = unit cost of $0.1223. thus, each apple cost $ .1223.

.1223 × 65 apples= $7.95

note_rounding apples to .12*65=$7.8

Why are peer reviews important?

Answers

Answer:

Peer reviews are important because individuals with similar background knowledge are used to review work to detect inaccuracies or deficiencies in the work.

Explanation:

Those individuals with similar educational and work background knowledge can more accurately review work since they have the required knowledge base for the subject.

Answer and explanation;

Peer review is a very important process that authors have to go through before they are able to publish their research manuscript. The main purpose is to ensure that whatever comes out published is in its excellent form, i. e., virtually free of errors.

Benefits;

1, Corrects vague terms
2, Provides feedback as to the effectiveness of your communication

Why do electromagnetic waves not require a medium for travel?A) because electromagnetic waves travel too fast for stationary particles to move with them
B) because electromagnetic waves transmit energy without compressing the particles of the medium
C) because electromagnetic waves generate their own particles for compression and use these for movement
D) because electromagnetic waves move in two-dimensional space, the particles of mediums exist in 3-D space

Answers

The answer is B) because electromagnetic waves transmit energy without compressing the particles of the medium. Electromagnetic waves are not like mechanical waves (ex. sound waves) because they do not need a medium to propagate. Electromagnetic waves continuously propagates as electric fields and magnetic fields generate each other.

Answer:

B) because electromagnetic waves transmit energy without compressing the particles of the medium

Explanation:

Electromagnetic waves are the combination of electric and magnetic field which will oscillate perpendicular to each other. And the propagation of wave here is perpendicular to both electric and magnetic field.

So here in this type of wave propagation we do not require any medium as this is propagation of electric and magnetic field.

So here no need of compression or rarefaction of medium molecules and hence it do not need any medium to travel

so here correct answer is

B) because electromagnetic waves transmit energy without compressing the particles of the medium

In the Niagara Falls hydroelectric generating plant, the energy of falling water is converted into electricity. The height of the falls is about 48 meters. Assuming that the energy conversion is highly efficient, approximately how much energy is obtained from one kilogram of falling water? Therefore, approximately how many kilograms of water must go through the generators every second to produce a megawatt of power (106 watts)?

Answers

Answer:

2.124 kg of water

Explanation:

height of the falls is about 48 meters.

Mass of water needed is 1kg = 1000g

Power needed is 106 watts.

The amount of energy in 106 watts in one sec is 106 joules.

To calculate the energy of the 1kg falling water = Mgh

Energy = 1000*9.81*48

Energy = 470880 joules.

1 megawatt is = 1000000watts

The kilogram of water needed is 1000000/470880 = 2.124 kg of water
