The frequency of a wave does not change as it passes from one medium to another.
What will most likely happen if a light wave moves from the air into a solid?
The speed of the light wave will remain the same.
The wavelength of the light wave will increase.
The wavelength of light will remain the same.
The speed of the light wave will decrease.
Answer:
B. The speed of the light wave will decrease.
Explanation:
The frequency of the waves doesn't change as it passes one medium to another as the speed of the light wave will get decrease. Thus option D is correct.
What is wave frequency?The waves frequency is the number of waves that has fixed oint in the iven amount if time and the unit tomeausre the wave freqiency is hertz.
Where one wave equaks to one fixed point in a second. The moe energy waves have a higher fequency than thoe of the less enegy waves. Thus the speed of the light waves will get decreased.

A track athlete throws a 2kg discus into a field with a velocity of 21m/s. What is the momentum of the discus?
Answer:
Given :
Momentum of disc = 42 kg m/s
Velocity of disc = 21 m/s
To Find :
Mass of the disc.
Solution :
❖ Momentum is defined as the product of mass and it's velocity..
Mathematically, p = m × v
p denotes momentum
m denotes mass
v denoted velocity
➛ It is a vector quantity having both magnitude as well as direction.
➛ It can be positive, negative or zero.
➛ SI unit : kg m/s or N s
By substituting the given values;
➙ p = m × v
➙ 42 = m × 21
➙ m = 42/21
➙ m = 2 kg
∴ Mass of the object is 2 kg.
Knowledge BoosteR :
As per newton's second law of motion, force is measured as the rate of change of linear momentum.
Formula : F = dp / dt
Describe the weather conditions for a Warm front.
Answer:
Explanation:
Warm fronts bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms.As the front passes over an area, the clouds become lower, and rain is likely. There can be thunderstorms around the warm front if the air is unstable.
What population distribution pattern works best when doing random sampling? Why.
A. Clump
B. Random
C. Uniform
Answer:
Dispersion or distribution patterns show the spatial relationship between members of a population within a habitat. Individuals of a population can be distributed in one of three basic patterns: uniform, random, or clumped.
Explanation:
How might long-term climate change affect the behavior of migratory birds that nest in the Arctic tundra?
Answer:
Climate change affects patterns of migration. Global warming also influences the routes of many migratory birds and their annual migration rhythm. A lot of migratory birds change their routes, shorten or completely cancel their journey as a result of changing temperatures.
Explanation: Hope this helps
Answer: well climate change can be many things like if it snows gets colder that means more nesting areas of it gets sunnier or hotter less nesting areas and if that happened then they would have to find different areas to nest at
Explanation:
How oxygen moves through an ecosystem
Answer:
Plants and animals use oxygen to respire and return it to the air and water as carbon dioxide (CO2). CO2 is then taken up by algae and terrestrial green plants and converted into carbohydrates during the process of photosynthesis, oxygen being a by-product.

What do pesticides, heavy metals, hazardous waste, mining for metals, mining for ores, all have in common?
Answer:
pollution of land and water
Explanation:
Pesticides, heavy metals hazardous waste and mining for metals or ores all cause land pollution.
These contaminate the land kill the useful microbes present in the soil. Moreover, when used excessively these chemical enter in our food chain and through into our body and cause various disease. Minamata disease in japan is one such example cause be mercury contamination.
These cause water pollution too. Chemical waste in water give rise to eutrophication and leaching.

Para que se utiliza el termómetro
Para medir la temperatura de una manera más exacta se utiliza un termómetro. Un termómetro es el instrumento que se usa para medir la temperatura del aire. Los termómetros más comunes son tubos de vidrio huecos. En la parte inferior del tubo se encuentra la ampolleta que contiene un líquido como alcohol o mercurio.
You find an organism growing on a dead log and after careful study, you determine that it is multicellular, heterotrophic, and its cells have cell walls. Given this information, you classify this organism into which kingdom
Answer: This is a plant organism due to it having cell walls but to be specific this is classified as being in the fungi Kingdom such as mushrooms.
Fungus grow on decaying or dead organisms to help break them down Hope this helps ^_^
Answer:
It is in the plant kingdom :) :)

WILL GIVE BRAINLISTTT!!! How can life and conditions on Earth be used as a model for life on other worlds?
Answer:
You can see the conditions of the other world, and see the composition of that world. This allows you to see what elements are abundant. Assuming there is water on that other planet, you can use the elements that are found there and see what organisms on earth are composed of those elements or use them.
Specifically, extremophiles (types of archaeabacteria) often exhibit characteristics that seem suitable for other planets. Using this, you can estimate what life on other planets have as characteristics, or even what they are made of.
Organisms with similar molecular makeups + organisms in areas with similar environmental pressures often exhibit anatomical + behavioral similarity. You can use this to model this.

4. Chromosomes are tightly coiled strands of DNA structures that exist in
pairs. Why do they exist in pairs?
Answer:
A - Because we inherit traits from both parents
Explanation:
We do not need 2 to hold all the DNA - as long as we have enough chromosomes, the pairing is not relevant.
