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

list and describe three factors that affect how quickly enzymes can work to catalyze reactions
Answer:
The correct answer is - temperature, pH, substrate concentration.
Explanation:
Various factors affect the rate of enzymatic reaction such as pH, temperature, substrate concentration, availability of activators or inhibitors in the reactions, and enzyme concentration.
Temperature: Temperature affects the rate of the enzyme-catalyzed reactions. Like most of the reactions with an increase in temperature rate of enzymatic reaction also rises up to a maximum level and then declines if the temperature continues to increase as enzyme denatures after a particular temperature.
pH: Similar to the temperature pH also increases the rate of reaction up to a maximum level and then declines the rate as every enzyme acts only at an optimum pH range.
Substrate concentration: If the substrate concentration is increased gradually while the concentration enzyme remains constant, the rate of reaction will increase until it reaches a maximum.

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 did you have to do to turn an atom that is labeled “+ion or -ion” into a “Neutral Atom”?
To make any neutral atom, it should balance an equal number of electrons and protons, with +ion having more protons, and -ion having more number of electrons.
What is a neutral atom?A neutral atom defines as an equal balance of electrons and protons, to make any atom into ions, it has to gain protons or electrons to make “+ion or -ion”.
All atoms are made of electron and proton in which their nucleus contains protons, a positive entity, and electrons, which surrounds the nucleus having a negative entity.
Ions are also a type of atom but have gain or loss of any number of electrons or protons. If any ion denotes +2 it shows having an extra number of protons.
Therefore, turning an atom that is labeled “+ion or -ion” into a “Neutral Atom” is done by adding or deleting the electrons.

How are pluripotent and multipotent cells different?
a. A multipotent cell can differentiate into any cell type within the body, but a pluripotent cell cannot.
b. A multipotent cell can differentiate into any cell type within the body, but cannot become extraembryonic like a pluripotent cell.
c. Multipotent cells make up most adult somatic cells, but they are not stem cells like pluripotent cells.
d. A multipotent cell can become many different types of specialized cell within a tissue or organ, but it is more limited than a pluripotent cell.
Answer:
D. A multipotent cell can become many different types of specialized cell within a tissue or organ, but it is more limited than a pluripotent cell.
Explanation:
Both pluripotent and multipotent cells are types of cells that can form multiple types of cells in the body. They are very similar, but there is one key difference. Multipotent cells are more limited than pluripotent cells. Pluripotent cells can form all cell types that make up the body. An example of pluripotent cells are embryotic cells. Multipotent cells are more limited, although they can develop into more than one cell type. Examples of types of cells that belong to this group are adult stem cells and cord blood stem cells.

A 20 N unbalanced force cause an object to accelerate at 1.5 m/s. What is the mass of the object?
Answer:
I believe it’s 13.33 m
Explanation:
Because a = Fnet / m
So if you plug the numbers in it’s : 1.5 m/s = 20n / m
Then you’ll want to cross multiply which it’ll be : 20n = 1.5m
Then you want to get m alone so you’ll divide 1.5 to both sides and that’ll leave you to
13.33 = m
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.

Coastal regions of continents tend to have ______ climates than inland regions due to the stabilizing effects of steady ocean temperatures.
A.hotter
B.milder
C.colder
Answer:
B.milder
Explanation:
Water has a higher heat capacity than soil and rock, so the ocean takes much longer to heat and
to cool than the land.
Coastal areas will generally have more moderate temperatures than inland areas because of the
heat capacity of the ocean.
Coastal regions of continents tend to have milder climates than inland regions due to the stabilizing effects of steady ocean temperatures. Thus option B is correct.
What Are the Different Climate Types?
Five most important climate types are Tropical, Dry, Temperate, Continental and Polar
Tropical climate include the hot and humid zone of climate where the average temperatures of this zone is greater than 64°F and 59 inches of precipitation per year.
Dry climate refers to the zones which are dry as in this zone moisture is rapidly evaporated from the air leads to little precipitation.
Temperate climate refers to the zone with warm and humid summers with some mild thunderstorms and winters.
Continental type of climate shows warm to cool summers, very cold winters with some snowstorms, strong winds etc.
Polar climate zone refers extreme cold, even in summer, the temperatures below 50°F .

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.
