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

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.
ver a long period of time, flower shapes and color variation have changed as a direct response to attract more pollinators, such as bees and hummingbirds. This is an example of --
Predation
Competition
Parasitism
Commensalism
Answer:
This is an example of parasitism
Ver a long period of time, flower shapes and color variation have changed as a direct response to attract more pollinators, such as bees and hummingbirds. This is an example of Predation. Thus, option A is correct.
What are predators?A predator is a creature that eats all or a portion of the body of its victim, which may be alive or recently deceased. Predators are distinguished from decomposers, such as fungus and bacteria, which break down the remaining remnants of dead species, by the phrase "living or recently killed."
We can confidently classify a lion as a predator if we witness it devouring a zebra. However, the zebra is included in the wide definition as well! Prey for a predator can include both plants and fungi as well as living things.
Additionally, a predator is not required to kill its victim. Instead, it can just remove a part of the prey's body and leave it alive, like a grazing cow or a bloodsucking mosquito. Herbivory is the term for a predator-prey situation in which an animal or insect eats a plant; herbi- stands for plant, and -vory implies eating.
Therefore the correct option is B.

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 :) :)

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.

NEED HELP ASAPPPP!!! PLEASEE
Answer:
1. The meaning of a diploid chromosome is a chromosome that has two complete pairs (sets) of chromosomes (from each parent).
2. Muscle cells, bone cells, blood cells, skin cells, and nerve cells are all diploid. (most cells are minus reproductive ones).
3. Haploid chromosomes are chromosomes that only has only a single set of chromosomes that don't have pairs.
4. Reproductive cells are haploid
7. A dog would have 39 pairs of chromosomes (hence the total 78 chromosomes).
8. A dog's reproductive cell would have half of the diploid cell because it is haploid so it would have 39 chromosomes.
10.The only haploid cell out of the 5 options is the ovum/sperm cell because they are the only reproductive cells (and reproductive cells are always haploid unless they combine to make a pair and form a zygote)
Hope this helps! :D

The process of natural selection relies on variation within a population or species and occurs when -
A. organisms that exhibit favorable adaptations increase in number compared to those less adapted, and therefor increase their chances of passing along favorable traits to future generations
B. asexual organisms are the result of the process of natural selection
C. organisms that have traits which are not helpful continue to reproduce and carry-on those traits
Answer:
A
Explanation:
by the definition of natural selection more fit organisms survive and reproduce more, propelling population change.

is the involuntary movement of the muscles that move food through the digestive system
Answer:
Preistalisis
Explanation:
Peristalsis, involuntary movements of the longitudinal and circular muscles, primarily in the digestive tract but occasionally in other hollow tubes of the body, that occur in progressive wavelike contractions. Peristaltic waves occur in the esophagus, stomach, and intestines.
