What if a wave reaches a type of matter it cannot pass through? Does
it just stop moving? If not, where does
it go?

Answers

Answer 1

Answer: It is bounced back. Like echoing, it's basically the sound wave hitting the matter it can't go through and bounce back.

Answer 2

Answer: if it hit the matter that it cannot pass through.....according to the velocity of wave..it might get reflected back....we can find sound waves reflecting back in closed rooms...because of the presence of the matter through which it cannot pass....and...it's because of this tht...echo is observed

This would be an illustration of Newton's first law of motion. Law of inertia, an object moving at constant velocity will keep moving at constant velocity until a force is acted upon it. Inertia is the tendency of an object to keep moving in a particular direction resisting to change, unless a force acts upon the object.

Coal _____. is a renewable resource can easily be replenished is formed from plant remains is the least-polluting energy source

Answers

Coal . . . . .

-- is a renewable resource that can easily be replenished.
It happens by itself, and you don't even need to do anything,
but it takes several million years.

-- Is formed from plant remains, and

-- is perhaps the MOST polluting energy source.

There is only supposed to be one answer choice, so the correct answer is is formed from plant remains.

PLEASE help me with these questions as soon as possible i need to turn it in!!!!A 60 watt light bulb uses 60 joules of electrical energy every second. However, only 6 joules of electrical energy is converted into light energy each second.
a. What is the efficiency of the light bulb? Give your answer as a percentage.

b. What do you think happens to the “lost” energy?

19. The work output is 300 joules for a machine that is 50% efficient. What is the work input?

20. A machine is 75% efficient. If 200 joules of work are put into the machine, how much work output does it produce?

Answers

a. I believe this might be the answer but
6 J/60 J= .1
.1 x 100= 10%

b. I'm not sure of this question

19. I'm not sure if I did this correct way or if there is a better way (I'm rusty)
300 J/.50 %= 600
600/100= 6 (answer)

20. (200 J)(.75%) = 150 (answer)
Check:
Efficiency: output/input x 100
150 J/200 J= .75
.75 x 100= 75%

Extend the life of your __________ by avoiding fast starts, stops and sharp turns.(A) ignition
(B) exhaust
(C) oil filter
(D) tires

Answers

Answer:

Tires.

Explanation:

There are the few steps which are discussed below should be taken to increase or extend the life of tires.

(1) Avoid fast starts: Fast start of the vehicle will increase the pressure on the tires due to the friction between the tires and the road will decrease the life of tires.

(2) Avoid fast stop: Fast stop of the vehicle will also increase the pressure on the tires due to the friction between the tires and the road will decrease the life of tires.

(3) Avoid sharp turns: The alignment of the wheels and tires are in such a way that they work properly when vehicle is drive in a straight path but sharp turn will increase the uneven pressure on the tires will lead to decrease the life of tires.

Therefore, the life of tires can be extend by avoiding all the above mention actions such as fast stop, start and sharp turns.

Final answer:

The life of tires can be extended by avoiding fast starts, stops and sharp turns. These maneuvers cause excessive friction which leads to quicker deterioration. Suitable driving habits can extend the life of the tires.

Explanation:

You can extend the life of your tires by avoiding fast starts, stops, and sharp turns. When a driver performs a fast start, a large amount of friction is produced between the tires and the road, causing the tires to wear faster. The same goes for abrupt stops and sharp turns, which also produce an excess amount of friction, leading to a quicker deterioration of the tires.

Therefore, to extend the life of your tires, it is advisable to drive in a cautious and considerate manner, avoiding fast starts and stops and refraining from making sharp turns whenever possible.

The equation NaCl →Na +Cl is a ______ reaction. A. decomposition B. single displacement C. synthesis

Answers

The correct answer is (a.) decomposition. The equation NaCl --> Na + Cl is a decomposition reaction. That is because the synthesis reaction looks like this Na + Cl = NaCl, and is the opposite of the decomposition. The decomposition reaction is the chemical reaction in which a single compound break into new compounds.
