Plz help with this digestive system

Answer:

This energy is mostly seen when the ball is kicked in the air. It is called potential energy because it has the potential to do work. If the soccer ball is raised to a certain height, at the top, before it gains Kinetic Energy, it has the Potential stored that it will be used once it starts to move.

Answer:

Physical change is when change occur physically in a substance. It is usually reversible. It includes change in colour, shape, texture, volume etc.

Examples: Cutting of paper, making moulded stuff from dough etc.

Chemical change is when change occurs chemically in a substance. It is non-reversible. When ever a physical change happens, a new substance if formed.

Examples: Burning of paper, transformation of milk into curd etc.

Answer:

Here are five important characteristics: wavelength, amplitude, frequency, time period, and velocity. The wavelength of a sound wave can tell the distance that wave travels before it repeats itself. The wavelength itself is a longitudinal wave that show compression and rarefactions of sound waves.

Explanation:

Radiation is an invisible force that can be deadly or helpful. So the only way it can move is by another invisible force.

Answer:

As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.

Answer:

when trees are cut down it reduced the amount of CO2 being converted into oxygen

Answer:

Deforestation contributes to global warming because with trees being cut down there is less oxygen being made and no trees to take in the carbon dioxide that is being produced. So without trees to do the work, people build greenhouses which uses their own gas that makes the world warmer because it traps the heat from the atmosphere.

Explanation:

The difference between the number of neutrons between an atom of fluorine and an atom of argon is 12

The number of neutrons is obtained by subtracting the number of protons from the mass number of the atom. We can calculate the number of neutrons in each element given this information

Mass number of fluorine = 19

Atomic number of fluorine = 9

Mass number of Argon = 40

Atomic number of argon = 18

Hence;

Number of neutrons in fluorine = 19 - 9 = 10

Number of neutrons in argon = 40 - 18 = 22

Difference between number of neutrons in argon and number of neutrons in fluorine = 22 - 10 = 12

Answer:

they just add heat, then it turns to water vapor

Explanation:

The first h20 is water the arrow represents adding heat, and the second h20 represent water vapor (water as a gas)

Answer:

Boiling is not a chemical reaction. It is a physical reaction because after being heated up to a boil turning into steam, it eventually cools back down to water. Like evaporation and then rain.

Explanation:

Answer:

Yes

Explanation:

Water being burnt in a pot of fire results in H20 Gas.

Answer:When you boil water, the heat given off is a sign that chemical bonds are being broken and new ones are being fore broken.

Explanation: false Water boiling is a physical change and not a chemical change, therefore no bonds are broken.
