When a light switch is turned on, it releases more energy than it had when it was off. True or False. And Why?
Answer:
True
Explanation:
When activated it needs to burn energy, this excess energy will be released as heat, if it is off it releases no energy will be used therefore no energy will be released.

Answer: Stamen, the male reproductive part of a flower. In all but a few extant angiosperms, the stamen consists of a long slender stalk, the filament, with a two-lobed anther at the tip. The anther consists of four saclike structures (microsporangia) that produce pollen for pollination. The main flower parts are the male part called the stamen and the female part called the pistil. The stamen has two parts: anthers and filaments. The anthers carry the pollen. The four main parts of a flower are the petals, sepals, stamen, and carpel (sometimes known as a pistil). If a flower has all four of these key parts, it is considered to be a complete flower.

A particular state of matter has atoms that are packed closely together and vibrating in fixed positions. A phase change occurs and the matter changes to a state where the atoms are spaced far apart and are moving about randomly. What can you infer has occurred?
Answer:
it goes to a solid to a liquid
Explanation:
When something is a solid the molecules are impact together and have a small sense of vibration. But as the solid melts away for example ice, the molecules become more loose forming into a liquid

explain what a convection current is?
who ever sees this I hope you have a wonderful day!
Answer:
Convection currents are flowing fluid that is moving because there is a temperature or density difference within the material.
Because particles within a solid are fixed in place, convection currents are seen only in gases and liquids. A temperature difference leads to an energy transfer from an area of higher energy to one of lower energy.

3. Answer INCREASE, DECREASE or REMAIN THE SAME. Explain your answer.
a) The density of water _______ as water changes from liquid to steam.
b) As the temperature increases, the rate of diffusion of a gas _______.
c) At constant volume, if the temperature of a gas is decreases, its pressure _______.
Answer:
a) decrease
b) increase
c) decrease
Explanation:
a) The density of water decreases as water changes from liquid to steam.
The density of substances are higher when their molecules are very close to each other having strongest bonding forces. When water is change from liquid to steam it means water molecules are not close to each other as they are in liquid state because now water is changed into gaseous form and molecules are further apart from each other. Thus, density goes to decrease.
b) As the temperature increases, the rate of diffusion of a gas increase.
As temperature increases molecules gets more kinetic energy and rate of diffusion increases.
c) At constant volume, if the temperature of a gas is decreases, its pressure decreases.
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
As temperature decreases its pressure also goes to decrease and vice versa.
2. What is true about the position of all metals in
the periodic table?
A. They are in the first group.
B. They are in the bottom period.
C. They are in the rightmost column.
D. They are to the left of the zigzag line.
Answer: D they are to the left of the zigzag line.
Explanation:
The first group are alkali metals and therefore wrong. The zigzag line is composed of semimetals and to the left we have metals like magnisum and metals are always bottom right in the table.

What kind of engine does a hybrid car use?
A. gasoline and solar
B. gasoline
C. gasoline and electric
D. electric and solar
Answer:
D. Electric and solar
Answer:
Gasoline and Electric
Explanation:
Quite simply, a hybrid combines at least one electric motor with a gasoline engine to move the car, and its system recaptures energy via regenerative braking. Sometimes the electric motor does all the work, sometimes it's the gas engine, and sometimes they work together.
What part of a plant is most likely to show negative phototropism
Answer:
Different organs of the plant may exhibit different phototropic reactions to different wavelengths of light. Stem tips exhibit positive phototropic reactions to blue light, while root tips exhibit negative phototropic reactions to blue light. Both root tips and most stem tips exhibit positive phototropism to red light.

\Which layer is between the crust and the asthenosphere?
Answer:
Lithosphere
Explanation:
Answer:
Lithosphere
Explanation:
The Lithosphere is the outermost layer of the Earth of about 100km thick and it is a rigid layer that includes the brittle upper portion of the mantle and the crust. Lithosphere is the hard outer region which includes all of the crust and the uppermost mantle.
Does phosphate have the ability to conduct electricity?
Answer:
Red phosphorous can vary in colour from orange to purple, due to slight variations in its chemical structure. The third form, black phosphorous, is made under high pressure, looks like graphite and, like graphite, has the ability to conduct electricity.
Explanation:
How many molecules are equal to 3.52 moles of oxygen difluoride?
Answer:
3.52 moles are equal to 21.2 ×10²³ molecules
Explanation:
Given data:
Number of moles of oxygen fluoride = 3.52 mol
Number of molecules = ?
Solution:
The given problem will solve by using Avogadro number.
1 mole contain 6.022×10²³ molecules
3.52 mol ×6.022×10²³ molecules / 1 mol
21.2 ×10²³ molecules
Thus, 3.52 moles are equal to 21.2 ×10²³ molecules .

Choose a body system and write about what kind of music it would listen to. write 2 sentences for full credit.
Answer : Music is read differently in the brain than
nonmusical tones and is connected to many different areas of the brain. Learning music
relegates a larger part of the brain to recognizing and interpreting music. Listening to
music has also been found to have an effect on learning.
Answer:
The heart would listen to music with a nice rhythm as it beats to the song.
