The law of conservation of energy states that energy can neither be created nor destroyed. What does “conservation” mean in this law? I need the answer quickly

Answers

Conservation means to improve something to prevent loss or decay
That's why energy can't be created or destroyed

In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time.

Conservation used in this sense i would think would be referring to the act
the principle by which the total value of a physical quantity or parameter (such as energy, mass, linear or angular momentum) remains constant in a system which is not subject to external influence.

How are scientists monitoring and studying the effects on the herring?

Answers

Answer:Work by biologists and marine scientists over the past 10 years has covered such commercial resources as shrimp, scallops, herring and cod. Establishing tolerance levels for these and other species is one of the tools needed to determine how Barents Sea oil production can be pursued in an environmentally acceptable way. Tolerance levels are measured when a species is at the larval stage, the phase in its growth where it has the greatest vulnerability to oil pollution.

What are the properties of the layers of the Earth atmospheres

Answers

there are 4 atmospheric layers called troposphere, stratosphere, mesosphere, and thermosphere. those were all in order from top to bottom. the properties in the layers are temperature, air pressure, and humidity.

1. Earth is also divided into layers based on physical properties, such as whether the layer is solid or liquid. 2. The five physical layers are the lithosphere, asthenosphere, mesosphere, outer core, and inner core.

The ocean can be considered one massive food web. Remove one link from this food web and it can have devastating effects on the ecosystem. Why is it important that scientists and researchers study declines like this?

Answers

Answer:because if 1 link is removed the other link wouldn't have anything to eat.sorry if this is incorrect:>

Explanation:

If it is a predator then whatever they eat will overpopulate and their will be a lot of them in the ocean if it’s a prey then the stuff that eats them could die out because they have no source of food or the predator will have no choice but to eat other predators sources of food and make it harder for the other predators in the ecosystem to eat food

The lowest point in the state of Louisiana is New Orleans. The city’s elevation is 8 feet below sea level. Write the elevation of New Orleans as an integer.

Answers

Answer:

-8

Explanation:

sea level is another way of saying zero. If something is above or above sea level it is a positive integer. like a regular number. if something is below sea level it is a negative integer like negative numbers. They said 8 is the elevation but new orleans is BELOW sea level. that means the integer we are looking for is going to be a negative number. 8 is the number they told us and since it is below the sea level. The integer of new orleans that represents its elevation is -8.

Since it’s BELOW sea level it would be -8 or 8 units to the left of zero

Predict: Will a 1500 kg car moving at the same speed as the tennis ball have more momentum or less? (i think more)
Calculate the momentum of the car and record it here.

Answers

Answer:

The car will have more momentum because it has a greater mass. Momentum= mass x velocity therefore if both the objects have the same velocity.

It will have more momentum as it weighs more. If a tennis ball moving 5 mph hits you it don’t hurt a lot but if a car hits you at 5mph it will knock you over
