Explain its significance. Check all that apply. Check all that apply. In chemical and physical processes, matter exchanges energ

y either as heat or work or both with the surroundings. Systems with high potential energy tend to change in the direction of lower potential energy, releasing energy into the surroundings. In the exchanges, the total energy is always changed; energy is created and destroyed. In the exchanges, the total energy is always conserved; energy is neither created nor destroyed. Systems with low potential energy tend to change in the direction of higher potential energy, releasing energy into the surroundings. In only physical changes, matter exchanges energy with its surroundings.

The question is incomplete. Here is the complete question.

Explain the significance of the Law of Conservationof Energy. Check all that apply.

1) In chemical and physical processes, matter often exchange energy with its surrounding.

2) System with low potential energy tend to change in the direction of higher potential energy, releasing energy into the surroundings.

3) In the exchanges, the total energy is always conserved; energy is neither created nor destroyed.

4) In chemical and physical changes, matter never exchange energy with its surroundings.  

5) In the exchanges, the total energy is always changed; energy is created and destroyed.

6) Systems with high potential energy tend to change in the direction of lower potential energy, releasing energy into its surroundings.

Answer and Explanation: <em><u>Law of Conservation of Energy</u></em> states that total energy is constant in any process. It may change in form or be transferred from one system to another, but the total remains the same.

So, analysing each statement above, we have:

In chemical and physical processes, matter CAN exchange energy with its surroundings, so first and fourth statements are incorrect.

Systems with higher potential energy tend to change in the direction of lower potential energy, and can release energy into its surroundings, so sixth statement is correct.

As cited above, in exchanges, total energy is always conserved, i.e. it is always constant, which means inside the system, energy is being transformed into another type of energy or transferred to other matter. Fifth statement is correct.

Where is heat transferred by radiation in a lava lamp
GuDViN [60]

Answer:

Explanation:

A lava lamp consists of oil, and wax in a glass, and a heat source (a light bulb) placed underneath the glass. When the lamp is turned on the bulb gets hot. As the bulb heats up some of the heat from the bulb is transferred to the glass by radiation.

On Earth, plasma exists in the ionosphere, in flames, and in chemical and nuclearexplosions. Matter in a controlled thermonuclea
nasty-shy [4]

The cost of developing thermonuclear power with plasmabe defended because D. It can provide an inexpensive power source.

<h3>How did the cost of developing thermonuclear power defended?</h3>

The  cost of developing thermonuclear power defended becvause we can see in the paragraph how it was told that the generation of ths power can be donee through the understanding of  the occurrence of plasmain nature,

It should be noted that this  thermonuclear power with plasmabe  posses the characteristics which make it to exist in the ionosphere, and it can be felt in the flames as well; as in the chemical and nuclearexplosions.

In conclusion the power can be seen as an inexpensive source power because the p[roduction of this power cn be found in most of the thing that can be found around us as discused above.

Therefore, option D is correct.

When a pendulum is at the midpoint of its oscillation, hanging straight down, which statement is true?
Svetach [21]
When a pendulum is at the midpoint of its oscillation, hanging straight down ...

-- that's the fastest it's going to swing, so its kinetic energy is maximum;
and
-- that's the lowest it's going to get, so its potential energy is minimum.

'c' is your choice.

A heavy rope, 60 ft long, weighs 0.7 lb/ft and hangs over the edge of a building 140 ft high. (a) How much work W is done in pul
Marina CMI [18]

Answer:

5880lb-ft of work is done

Explanation:

The length of the heavy rope is given as 60ft and the weight per length is 0.7lb/ft.

Therefore, the total weight of the heavy rope is

60×0.7 =42lb.

The work done in pulling the heavy rope to the top of the building is w = Fd.

Where

F is force is measured in pounds;42lb

d is distance through which the heavy rope is to be pulled measured in feet; 140ft

w= 42lb×140ft= 5880lb-ft
