Answer: An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.

The acceleration of an object depends on the mass of the object and the amount of force applied.

Whenever one object exerts a force on another object, the second object exerts an equal and opposite on the first.

HELP! 100 POINTS! A cinder block is pulled 0.50 meters to the right in 3 seconds. What is the block's average speed to the nearest hundredth of a meter per second (m/s)?

Answers

Answer:
The average speed of the blocks are 0.36 m/S.
Explanation:
Average speed is defined as the ratio of distance covered per unit time. So if it is said that blocks are pulled to 0.9 m in the right side. This means the blocks cover a distance of 0.9 m from the origin and that distance is covered in 2.5 s. Thus, the average speed can be calculated from the change in speed
with respect to time. As at time t = 0, the speed is
also zero, and at time t = 2.5 s, the speed will be
Speed =
0.9 = 0.36
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.

Speed = 0.9 = 0.36
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.

Answer:

Static Electricity! :)

Explanation:

Argument 1
The water in the puddle that Claire observed evaporated. The highest temperature was 32°C (90°F). Since the puddle was there in the morning and gone later in the day, it must have evaporated.

Argument 2
The water in the puddle that Claire observed evaporated. Since the highest temperature was 32°C (90°F), we know that it was a warm day. When water gets hot, it can change from liquid to gas. This is called evaporation. I think the water became so warm that it became water vapor (gas), and that’s why the puddle was gone by the afternoon.

When a chemical reaction occurs, what happens to the atoms of the two substances? Provide an example from the Sim (on Amplify) as evidence to support your answer.

When a chemical reaction does not occur, what happens to the atoms of the two substances? Provide an example from Sim as evidence to support your answer.

Answers

When a chemical reaction occurs, the atoms of the two substances are rearranged to form new compounds. During the reaction, the bonds between the atoms are broken and new bonds are formed, resulting in the formation of new substances with different chemical properties than the original substances.

An example of this can be seen in the Sim on Amplify, where students can experiment with different chemical reactions. For instance, in the "Chemical Reactions" Sim, students can explore the reaction between iron and sulfur to form iron sulfide. In this reaction, the iron atoms and sulfur atoms combine to form a new compound, iron sulfide, with different properties than the original iron and sulfur. The atoms of the iron and sulfur are rearranged to form new bonds, resulting in the formation of a new substance. This is an example of a chemical reaction, where the atoms of the two substances are rearranged to form a new compound with different properties.

Answer:

Explanation:A chemical response is a chemical transformation in which two chemicals combine to create a third component.

(i) Adding diluted acid to an active metal causes the test tube to heat up and hydrogen gas to escape, which results in the production of heat.

(ii) When diluted hydrochloric acid is added to silver nitrate, AgCl, a white precipitate, results.

(iii) When water is added to quicklime, the mixture boils and produces heat along with a hissing sound.

(iv) Thermal breakdown of mercury oxide - Mercury turns from red to a metallic silver tint as a result of this process.

Hey Lenny lately I’ve been having a rough time in the water cycle. It all started when I was chilling in my favorite location the “glaciars” and suddenly the sun turned me into liquid form. Next thing I know I am hurdling down a river straight into a massive lake. Personally this is my least favorite stage of the water cycle because of kids and bacteria that lurk in the water, very scary things. I didn’t stop at the lake very long, and instead sunk into the soil in a process called collection so I could become ground water. Underground reservoir’s are much more peaceful then lakes and I wanted to stay there. However I was forced up a water well pump shortly after and sent through a long tube. Me and couple of the friends I met on the way were all dispersed over a giant grass feild. Many molecules in the group were captured by the hostile plants but I escaped through the means of evaporation. Currently I have condensed into cloud form and I am roaming the skies looking for you, when you get this let me know and I’ll percipitate in your area!

Carbon and Hydrogen.

Answer:

Mostly decaying organisms are needed to present in marine mud to form fossil fuels.

Explanation: When organisms and plants died and sank to the bottom of swamps and oceans, brown soil-like materials called peat are formed.

Photosynthesis uses all of the following except _____ to make food.

Multiple choice question.

A)
carbon dioxide

B)
chemical energy

C)
light energy

D)
water

Answers

Answer:

Photosynthesis uses all of the following except _____ to make food.

B) Chemical Energy

Photosynthesis is a process that takes place due to water, sunlight, carbon dioxide and creates oxygen.

All the green plants carry out the process of photosynthesis in the presence of sunlight, the carbon dioxide, and water.

Thereby releasing oxygen and energy. The first organism that evolved to make photosynthesis was the blue-green algae and later on, cyanobacteria evolved which lead to the origin of oxygen on the earth.

Thus the photosynthesis is a process that results when all three are processes by the plants.

Giving out the chemical energy in the form of sugar and air to breathe. Hence the correct option is B.

Answer:

B.) Chemical energy

Explanation:

carbon dioxide + water ---[in the presence of light energy]---> glucose + oxygen

Question 25———-A, YA are two isotopes of element A.
Difference between the number of neutrons
in the isotopes is?

Answers

Answer:

Option C. 1

Explanation:

Step 1:

Determination of the Neutron of both isotopes. This is illustrated below.

For isotope y xA:

Mass number = y

Atomic number = x

Neutron =..?

Atomic number = proton number = x

Mass number = Proton + Neutron

y = x + Neutron

Rearrange

Neutron = y – x

For isotope (y + 1) xA:

Mass number = y + 1

Atomic number = x

Neutron =.?

Atomic number = proton number = x

Mass number = Proton + Neutron

y + 1 = x + Neutron

Rearrange

Neutron = y + 1 – x

Step 2:

Determination of the difference between the neutron number of both isotopes. This is illustrated below:

For isotope y xA:

Neutron number = y – x

For isotope (y + 1) xA:

Neutron number = y + 1 – x

Difference in neutron number

=> (y + 1 – x) – (y – x)

=> y + 1 – x – y + x

Rearrange

=> y – y + 1 – x + x

=> 1

Therefore, the difference in the neutron number of both isotopes is 1
