If a hot liquid is poured into a cup, the cup will soon feel warm. How does the increase in temperature change the particles that make up the cup?

Answers

Answer:

Adding energy (heating) atoms and molecules increases their motion, resulting in an increase in temperature.

Removing energy (cooling) atoms and molecules decreases their motion, resulting in a decrease in temperature.

Energy can be added or removed from a substance through a process called conduction.

In conduction, faster-moving molecules contact slower-moving molecules and transfer energy to them.

During conduction the slower-moving molecules speed up and the faster-moving molecules slow down.

Temperature is a measure of the average kinetic energy of the atoms or molecules of a substance.

Heat is the transfer of energy from a substance at a higher temperature to a substance at a lower temperature.

Some materials are better conductors of heat than others.

D) cell respiration


Photosynthesis is the primary funtion of the leaves.
Explanation:
Photosynthesis is defined as the chemical process of converting light energy into chemical energy in a form of food or sugar. Leaves contain most of the chloroplasts in plants that are responsible in capturing light for photosynthesis to occur.
Leaves are naturally green to serve their purpose. This green color is caused by the reflection of the green portion of the visible light spectrum by the green coloring pigment, chlorophyll. Chlorophyll, that is contained in chloroplasts, captures certain wavelengths of light, as energy to initiate photosynthesis. As a result, we get food from plants.

What is a natural way to control an aphid population?

release ladybugs into habitat
praying mantis
insecticide

Answers

Answer:

I would say that the answer is A, or releasing ladybugs into a habitat.

Explanation:

This is the only "natural" way to control an aphid population. However, please note that as well as ladybugs, praying mantis's also eat aphids. But, the answer choice doesn't describe the option very well, so that is why I say that it is A.

Hope it helps!

The natural way to control an aphid population is release ladybugs into habitat. The correct option is 1.

What is Ladybug?

Ladybugs are natural aphid predators that can consume large numbers of them, assisting in population control without the use of harmful chemicals.

A natural way to control an aphid population is to release ladybugs into the aphid's habitat.

Although praying mantises are natural predators of aphids, they are less effective at controlling their population than ladybugs.

Insecticides, on the other hand, are chemical treatments that can be harmful to both beneficial insects and the environment.

As a result, using insecticides to control aphid populations is not a preferred method, particularly in natural or organic settings.

Thus, the correct option is 1.

Moving a book to a lower shelf decreases potential energy.
True
False

Answers

Answer:

True

Explanation:

Moving a book so the potential energy of the system decreases is a true statement.

What is potential energy?

A book's potential energy is reduced when it is moved to a lower shelf. A charge's electric potential energy is decreasing if it is traveling in the direction that it would typically go.

A charge's electric potential energy increases if it is pushed in the opposite direction from how it would ordinarily travel.

Since the potential at the Earth's surface is zero, gravity always has a tendency to draw items toward the planet's center, this causes the potential energy to be reduced.

Therefore moving the book to a lower shell change potential energy, which decreases.

A

Explanation:

I hope this helps :)

Answer:

1 - D

2 - B

3 - A

4 - A

Explanation:

Hello There!

D=Distance

T=Time

S=Speed

For the first one we are given the speed and the time and we need to find the distance

To do so we multiply the two together( the two meaning the speed and the time)

They run 20 m per second and

if they run for 40 second

(20*40=800)

they will run for a total of 800m therefore the answer to the first one is D

for the second one we are given the distance and the time and we need to find the speed.

Looking at the formula chart we can find the speed by dividing the distance over the time

so speed = 80/5

80/5=16 so the speed is 16m/s (B)

For the third one we are given the distance and the time and we need to find the speed

Once again we can find the speed by dividing the distance over time

20/5=4 so the bunny hops 4m/s

For the last one we are given the speed and the distance and we need to find the time it took to get to the associated distance

another way we can find the time is by dividing the given speed by the distance

so time = 1500/250

1500/250=6 so it will take the space ship 6 seconds to reach a distance of 1500m
