Answer:
True
Explanation:
Friction is defined as the force that opposes motion when an object is sliding over a surface.
As a result of friction, all objects moving over a surface eventually come to rest over time.If we were to successfully create a friction-less surface, an object will remain in motion forever because it will encounter no opposition to its motion.
Hence, the resistance to the motion of objects over a surface which causes the objects to come to a halt after moving over the surface for some time is called friction.

Why do clothes stick together when coming out of a dryer? And do the clothes start off as neutral?
here is what came up when i searched it up:
"The attraction between protons and electrons can also make clothes stick together in the dryer. When you dry clothes in the dryer, different fabrics rub together, and electrons from a cotton sock (for instance) may rub off onto a polyester shirt."
Sometimes, clothes can get stuck together after they come out of a dryer because of static electricity.
No, clothes may not start off as neutral. Whether clothes have static charges before going into the dryer depends on different things.
Why do clothes stick together when coming out of a dryer?Static electricity happens when certain things touch and create an uneven amount of electrons. This can cause one material to have a positive charge and the other to have a negative charge. When clothes move and touch each other in a dryer, this rubbing can cause static electricity.
If the clothes are cleaned and dried correctly, they should have no charge or be evenly charged.

Which of the following has more calories: table sugar or aspartame? Explain.
Answer: aspartame has more
Explanation: Aspartame contains 4 calories per gram (g), similar to sugar. It is, however, around 200 times sweeter than sugar. This means that only a tiny amount of aspartame is necessary to sweeten foods and drinks. so answer is aspartame
Aspartame has more calories. Why? Because aspartame manufactures four calorie kilograms of energy per gram when it's transfigured. Why is table sugar not the answer? Because table sugar manufactures 3.9 calorie kilograms. Also, aspartame is 200 times as sweet as table sugar, so it is eaten in much smaller portions. So your answer would be aspartame.

Answer:C
Explanation:
The seasons of the Earth are the result of --
a
the tilt of the Earth and its orbit around the Sun.
b
the Sun having a large gravitational pull.
c
the orbit of the moon around the Earth.
d
the continual rotation of the Earth on its tilted axis.
Answer:
the tilt of the Earth and its orbit around the Sun.
Explanation:
The seasons on the earth is as a result of the tilt of the earth and its orbit around the sun.
These phenomenon causes the four seasons of the earth. The earth is tilted at an angle of 23.5° from the perpendicular.
This causes the differences in yearly exposure of parts of the earth to solar radiation.
At some points, a part can experience very high insolation whereas it is low in other parts.
These variations results in the seasons on the earth.

Identify the Lewis acid in this balanced equation:
Upper A g superscript plus, plus 2 upper N upper H subscript 3 right arrow upper A g (upper N upper H subscript 3) subscript 2 superscript plus.
Answer:
1
Explanation:
Ag+
From the given reaction, it is clear that, Ag is gaining electrons from the base NH₃ . Hence, according to Lewis concept of acids and bases, Ag⁺ is the Lewis acid.
What is Lewis concept of acids and bases ?There are various concepts to define acids and bases. Among which the first was Arrhenius theory. This theory states that, acids are substances which can furnish H+ in solution and bases are substances giving OH- in solution.
Then Bronsted- Lowry concept states acids as proton donor and bases as proton acceptors. The most applicable theory for acids and bases is Lewis concept.
According to Lewis theory of acids and bases, acids are electrons acceptors and bases are electron donors.
The given reaction is written as:
[tex]\rm Ag^{+} + 2NH_{3} \rightarrow Ag(NH_{3})_{2}[/tex]
Here, Ag⁺ is the Lewis acid which accepts an electron from the Lewis base NH₃.

Which action occurs in the third stage of cell division?
The nuclear membrane disappears.
The nuclear material of a cell is copied exactly.
The cell forms two nuclei.
The nuclear material separates, with half moving to either side of the cell.
Answers:
1. People generally experience rapid growth for a second time between the ages of 15 and 20
2. The endocrine system contains the pituitary, adrenal, and thyroid glands.
3. The nuclear membrane disappears in the third stage of cell division?.
Explanation 1:
Between the ages of 15 and 20, puberty causes the release of multiple hormones, which causes rapid growth among other things.
Explanation 2:
The reproductive system contains the ovaries (female) and testes (male).
The endocrine system contains the pituitary, adrenal, and thyroid glands.
The circulatory system contains three independent systems that work together, the heart (cardiovascular), the lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic).
The respiratory/pulmonary system contains the nose, mouth, throat (pharynx), voice box (larynx), windpipe (trachea) , airways (bronchi) , and lungs.
Explanation 3:
Mitosis is the process in cell division where the nucleus divides into two nuclei, each with an identical set of chromosomes.
Interphase: occurs when the cell begins to replicate the nuclear DNA material
Stage 1 - Prophase: chromosomes begin to undergo a condensation process that will continue until metaphase. The spindle also begins to form as the two pairs of centrioles move to opposite poles.
Stage 2 - Prometaphase: Chromosomes are pulled in opposite directions by microtubules growing out from both poles of the spindle until balanced.
Stage 3 - Metaphase: The centromeres of all the cell's chromosomes line up at the equator of the spindle.
Stage 4 - Anaphase: The chromosomes move away from one another to opposite poles of the spindle.
Stage 5 - Telophase and Cytokinesis: The chromosomes reach the poles, the nuclear membrane then reforms, and the chromosomes begin to decondense. This is followed by cytokinesis, or the division of the cytoplasm into two daughter cells.
Most of my sources say that the nuclear membrane occurs during prophase, but the stages are listed in this order. Regardless, your answer would be A. The nuclear membrane disappears.

Santiago's car has an overall average speed of 25 cm/s. If he could increase his car's overall average speed by 10%, what would his car's new overall average speed be?
Given:
The overall average speed = 25 cm/s.
The overall average speed increased by 10%.
To find:
The new overall average speed.
Solution:
We have,
Overall average speed = 25 cm/s.
The overall average speed increased by 10%. So, the new average speed is
New overall average speed = Initial average speed + 10% of initial overall average speed
[tex]\text{New overall average speed}=25+\dfrac{10}{100}\times 25[/tex]
[tex]\text{New overall average speed}=25+2.5[/tex]
[tex]\text{New overall average speed}=27.5[/tex]
Therefore, the new overall average speed is 27.5 cm/s.
