Which of the following colors is/are produced when white light from sun is passed through a prism?
Answer:
Options d.
Explanation:
As white light from the sun is passed through a prism, it is separated into colors - red, violet, yellow, blue, green, orange, and indigo.
Dispersion is the process of the separation of visible light into its different component colors. The light waves are refracted as they enter the prism.
So, option d. is correct.

Explanation:
Which of the following would cause the seasons on Earth to change more gradually?
A Increasing the amount of time it takes Earth to orbit the Sun.
B Increasing the number of times Earth rotates on its axis per year.
C Decreasing the speed of the Moon’s orbit around Earth.
D Decreasing the amount of energy the Sun emits per year.
Answer: The four seasons happen because of the tilt of the Earth's axis. At different times of the year, the sun's rays hit different parts of the globe more directly. The angle of the Earth's axis tilts the Northern Hemisphere towards the sun during the summer.

Explanation:
if freshwater is added to a region, what happens to seawater density and salinity?
Answer:
The density and salinity goes down.
Explanation:
Salt water is denser than pure water. As fresh water is added to salt water the concentration of salt goes down. Since salinity is the amount of salt in the water that would go down with the concentration. This would also mean that the density goes down since there is less salt per unit of volume which makes it so that there is less mass per unit of volume. The formula for density is d=m/v so as the mass goes down per unit of volume so does the density.
Let me know if anything is unclear in the comments and we can try to work through it.

2 The polar structure of water allows it to act as a solvent for many substances. Which of the
following statements best explains why water is considered polar?
F The unequal sharing of electrons results in the water molecule having a slightly negative
charge near its oxygen atoms and a slightly positive charge near its hydrogen atom.
G The equal sharing of electrons by the hydrogen and oxygen atoms form weak bonds that are
easily broken during dissociation.
H The unequal sharing of electrons results in the water molecule having a slightly positive
charge near its oxygen atoms and a slightly negative charge near its hydrogen atom.
The equal sharing of electrons by the hydrogen and oxygen atoms create a molecule that is
neutrally charged
Answer:
Explanation:
Why do nonpolar substances tend to be gases and not liquids or solids?
Answer:
Because the intermolecular interactions are weaker.
Explanation:
Nonpolar substances do not have dipole-dipole or hydrogen bond interactions, which are strong intermolecular interactions that often make the substance liquid or solid. Instead, they must rely on van der Waals forces, which are relatively weaker interactions that are often insufficient to hold the molecules together in liquid or solid form.
The magnitude of intermolecular association in nonpolar substance is much lower than the magnitude of intermolecular association in polar substances.
Polar substances are those substances in which a permanent dipole exists in the molecule. In a molecule having a permanent dipole, the electronegativity difference between the atoms bonded in the molecule is high.
As a result of this high electronegtivity difference between atoms, the molecules interact more intimately hence polar molecules tend to exist mostly as liquids and gases while nonpolar molecules having less intimate intermolecular interaction via dispersion forces exist mostly as gases.

Explanation:
When light pases through a prisim,white light will be separated into different colors. which statment best explains this observation?
Answer:
It's B
Explanation:
The classic rainbow is made of certain colors, so If a white light passed through a glass prism [and only glass] the rainbow would show because of the colors bending [the naked eye can't see that 0-0]
Also, you know the sky is blue right?? The color blue in that prism when the light shined over was the shortest and wavy color. each color has it's own wave. blue is just the shortest and waviest one.

In mitosis, how does a daughter cell compare with its parent cell?
A.
A daughter cell has twice as many chromosomes as its parent cell.
B.
A daughter cell has half as many chromosomes as its parent cell.
C.
A daughter cell and its parent cell are exact copies of each other.
D.
A daughter cell has no similarity to its parent cell.
Answer: im pretty sure its the last (one daughter cell has no similarity to its parent cell.)
Explanation: bc a daughter cell has 30 and the parent cell would have 46 and thats not twice or half as many and they arent the same either so the last one makes sences
Kate wrote the steps of the carbon cycle to describe how carbon is cycled through specific organisms. The steps are in random order.
1 - The rabbit decomposes.
2 - The rabbit eats the carrot plant.
3 - The carrot plant takes in carbon dioxide from the air during photosynthesis.
4 - Carbon compounds are returned to the soil.
Which lists the steps in order?
2, 3, 1, 4
3, 2, 1, 4
3, 4, 2, 1
2, 4, 3, 1
3, 2, 1, 4
Further explanation:The process of photosynthesis is the process of converting carbon dioxide and water into energy in the form of carbohydrates using sunlight. Usually done by plants that have leafy za called chlorophyll.
Carbohydrates themselves are formed from the C-carbon, H-hydrogen and O-oxygen components
Rabbit food is carrots that contain carbohydrates, which are part of the photosynthesis process
3. The carrot plant takes in carbon dioxide from the air during photosynthesis.
Reaction
6CO₂ + 6H₂O ⇒ C₆H₁₂O₆ + 6O₂
2. The rabbit eats the carrot plant.
Rabbits meet their carbohydrate source for energy by eating carrots
1. The rabbit decomposes.
Rabbits in time will experience a process of decomposition
4 - Carbon compounds are returned to the soil.
The carbon content in rabbits will also be decomposed into the soil again

Explanation:
Calculate the speed for a car that went a distance of 125
kilometers in 2 hours tiine.
Answer:
62.5 km/hr
Explanation:
Speed can be found by dividing the distance by the time.
s=d/t
We know the car travelled a distance of 125 kilometers in 2 hours. Therefore:
• d=125 km
• t= 2 hr
Substitute the values into the formula.
s= 125 km/ 2 hr
Divide
s= 62.5 km/ hr
The speed of the car is 62.5 kilometers per hour.
