Answer:

The atoms are just rearranged but there is no decrease or increase in the mass. A law fo conservation.

Explanation:

For my science class, we were doing Savvas too so I know the answer for this question.

According to the law of conservation of mass and as depicted in the model there are equal number of atoms of reactants and products , thus demonstrating that mass is conserved.

What is law of conservation of mass?

According to law of conservation of mass, it is evident that mass is neither created nor destroyed rather it is restored at the end of a chemical reaction .

Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.

Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Antoine Lavoisier in the year 1789.

Answer:

In explanation, these are the some I can think of that are basic.

Explanation:

Potential energy- Is an energy that is stored in something, like elastic. When you stretch it, you are creating potential energy.

Kinetic energy- Is an energy where something is being in motion. Like a roller coster, when you are being plunged to the bottom, you are witnessing kinetic energy!

Electrical energy- Is an energy which has to do with electric charge, like for example take a light bulb, and when you are putting it into it's place and it turns on, that is electrical energy flowing into the light bulb to turn it on.

Elastic energy- Is an energy where is you stretch elastic, you are creating energy that is compressed, and then letting it go.

C.Your land could stop producing vegetables altogether.
D.Your land will be worth less money.

Answers

B or d more both but hope it helps

If crops are not getting proper nutrients from soil we may have to apply fertilizers which adversely affect the soil if no nutrient is restored to soil, it will not produce vegetables and your land will be worth less money. Thus, options C and D are correct.

What are nutrients?

Nutrients are ions, minerals and proteins that is very essential for living things. Without proper nutrition, the growth of both plants and animals become will be declined.

Plants needs some elements such as nitrogen, potassium, calcium, phosphorus etc. for their growth. They absorbs these ions and water from soil and distribute all over its body through channels.

If plants are getting no nutrients from the soil their will not grow and no new vegetables will be formed in such a land where there on management to restore soil nutrients.

In such situations, we have to apply fertilizers which have may bad impacts too. Hence, without nutrients the vegetables will not grow and the land will be worth less of money.

Explanation:

The circuit in series works in a manner that, when one thing stops in the circuit, the whole circuit stops.

What is a circuit?

A circuit is the way of passage of electricity including the electrical devices, electrical wires, energy source such as battery etc. There are two types of circuits namely parallel circuit and series circuit.

In a parallel circuit, all the components are arranged in a parallel fashion. For instance if there are three resistors, each resistors will be parallel each other resistors.

In series circuits, all electrical components are arranged in a series. Thu for a group of bulbs, the second tail of first bulb is connected to the first tail of second bulb and so on. So that, the the effect of electrical current will be same for all.

Therefore, in a series circuit When one thing stops working, the whole circuit stops working.
