1) What is the acceleration of a 40 kg object pushed with a force of 400 N?
2) What is the force on an 800 kg rock being thrown at 2.5 m/s2?
3) What is the mass of a ball being rolled at 3.5 m/s2 from a 30 N force?
Answer:
a = 10 m/s²
F = 2000 N
m = 8.57 Kg
Explanation:
1) What is the acceleration of a 40 kg object pushed with a force of 400 N?
Acceleration of object = ?
Mass of object = 40 Kg
Force on object = 400 N
Solution:
Formula:
F = ma
by putting values,
400 N = 40 Kg × a
a = 400 N/ 40 Kg ( N = Kg.m /s²)
a = 10 m/s²
2) What is the force on an 800 kg rock being thrown at 2.5 m/s2?
Acceleration of object = 2.5 m/s²
Mass of object = 800 Kg
Force on object = ?
Solution:
Formula:
F = ma
by putting values,
F = 800 Kg × 2.5 m/s²
F = 2000 Kg. m/s² ( N = Kg.m /s²)
F = 2000 N
3) What is the mass of a ball being rolled at 3.5 m/s2 from a 30 N force?
Acceleration of object = 3.5 m/s²
Mass of object = ?
Force on object = 30 N
Solution:
Formula:
F = ma
by putting values,
30 N = m × 3.5 m/s²
m = 30 N / 3.5 m/s² ( N = Kg.m /s²)
m = 8.57 Kg

A woman has blood Type A, her baby has blood Type AB: Is it possible that a man who has the blood Type A could be the father? Show the Punnett Square and explain.
Answer:
No, it is not possible
Explanation:
Humans use the ABO blood group system where the A and B alleles are dominant over allele O but codominant with one another.
This system is such that;
Type A can only have genotype: iAiA or iAi
Type B can only have genotype: iBiB or iBi
Type AB can only have genotype: iAiB
Type O can only have genotype: ii
According to this question, a woman has blood Type A (iAiA or iAi) and her baby has blood Type AB (iAiB). This means that the father definitely contributed the allele B in order to have a baby with type AB. It also means that, according to the question, IT IS NOT POSSIBLE FOR A "Type A" father to produce that baby (see the punnet square attached).
Note: The father must contain an allele B in his genotype i.e. the father must be either type B (iBiB or iBi) or type AB (iAiB)

how soil gets affected by the repeated growing of crops in the same field how does use of fertilizers help the farmers
Answer:
Repeated growing of crops in the soil decreases the fertility of the soil as the crops use up the nutrients of the soil. ... Farmers replenish the soil of the depleted nutrition with the help of fertilizers or crop rotation. Fertilizers are chemical substances that are rich in a particular nutrient.
Answer:
a) repeated growing of crops in the soil results in decrease in soil fertility as the soil use up the nutrients of the soil .
b) as the farmers need to replenish the fertility of the soil they use chemical substances known as fertilizer . They help in maintaining and increasing the fertility content of the soil but overuse of fertilisers can harm the soil . So the fertilisers should be used in correct quantity .
What could happen if two of the base pairs on this strand of DNA were switched?
In the DNA structure if the two base pairs exchange it leads to creating a mutation in the sequence and makes different proteins, hence option A is correct.
How do DNA base pairs change the protein?A mutation is any kind of change that leads to the creation of an abnormal protein, DNA has genetic information to synthesize any kind of protein.
The process of transcription by which genetic information stored in the DNA is passed to the RNA, which translate this information to make the protein.
Protein is the final output of the genetic information stored in the organism's cell, if any change in the DNA sequence it affects the final functional structure of the protien.
Therefore, different protein is the result of the base pairs on this strand of DNA being switched.

How can one species turn into another species that is completely different
Answer:
Evolution
Explanation:
Answer:
One species does not "turn into" another or several other species -- not in an instant, anyway. The evolutionary process of speciation is how one population of a species changes over time to the point where that population is distinct and can no longer interbreed with the "parent" population.

A woman with Type O blood and a man who is Type AB have are expecting a child. What are the possible blood types of the kid? 2. What are the possible blood types of a child who's parents are both heterozygous for "B" blood type?
The possible blood type of offspring, when a woman with type O and a man who is type AB are expecting a child are A and B.
What are the types of blood groups?There are four kinds of blood groups which are A, B, AB, and O, based on the presence of antigens in RBC. Blood groups A and B show co-dominance, while O is recessive.
When a woman with type O blood and a man who is Type AB are expecting a child, the possible blood types are A and B. 50% of the children would have A blood type, and 50% of children would have blood type B, which are heterozygous.
When Parents are both heterozygous for the B blood group, then the possible blood group of offspring would be 75% B blood type (25% are homozygous and 50% are heterozygous) and 25% O blood type.

What term refers to how fast blood traveled from its source? _________ refers to how fast blood traveled from its source to where it landed.
Answer:
Impact.
Explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.
In Science, the study of blood is generally referred to as serology.
Impact refers to how fast blood traveled from its source to where it landed.
This ultimately implies that, an impact is a measure of the rate at which blood travels from its source to where it lands. The four (4) phases of impact includes;
I. Displacement.
II. Retraction.
III. Contact and collapse.
IV. Dispersion.
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
Generally, the right atrioventricular valve (AV) is also referred to as the tricuspid valve and is located on the right dorsal side of the human heart. The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.
