Why does the moon have a stronger gravitational effect on the earth then the sun?
Explanation:
The tidal forces of the Moon are much stronger than the Sun's because it is so much closer to our planet, causing a much greater variation in the gravitational force from one location to another. The Sun's gravitational force, on the other hand, varies much less because the Sun is so far.

How are stoichiometric calculations performed for redox reactions?
Answer:
(b) Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Explanation:
According to the law of conservation of mass, matter can neither be created nor be destroyed. However, it can be transformed from one form into another. During chemical reactions, atoms or ions are exchanged between reactants to form products. Thus, all the stoichiometric calculations are based on law of conservation of mass.
During redox reactions, one species is oxidized and other species is reduced. This involves electron transfer.
Using the human species as an example, explain why physical appearance or morphology is NOT always useful for identifying organisms belonging to the same species.

Which question is a scientist who studies the genetic engineering of crops most likely attempting to answer?
A. How can a more stable supply of crops be created?
В. How can natural selection create better crops?
С. How can crops be grown without a need for light?
D. How can the genetic variation of crops be increased?
Answer:
i think that it is A
Explanation:
the other ones did not make as much sense
A scientist who studies the genetic engineering of crops most likely attempting how more stable supply of crops be created. so, option A is correct.
What is genetic engineering ?Genetic engineering, often known as genetic alteration, is a technique that modifies an organism's DNA using technology developed in labs. This could entail altering a single base pair (A-T or C-G), erasing a section of DNA, or incorporating a new DNA sequence.
In order to fix genetic flaws and hence prevent or treat hereditary illnesses, gene therapy aims to change specific genes.
The goal of genetic engineering is to alter the genes to increase the organism's capabilities beyond what is typical.
The term "genetic engineering" originally applied to a number of methods for modifying or altering living things through their heredity and reproductive processes.
Thus, option A is correct.

Circle the letter next to each sentence that is true concerning the compressibility of gases. a. The large relative distances between particles in a gas means that there is considerable empty space between the particles. b. The assumption that particles in a gas are relatively far apart explains gas compressibility. c. Compressibility is a measure of how much the volume of matter decreases under pressure. d. Energy is released by a gas when it is compressed.
Answer:
The large relative distances between particles in a gas means that there is considerable empty space between the particles.
The assumption that particles in a gas are relatively far apart explains gas compressibility.
Compressibility is a measure of how much the volume of matter decreases under pressure.
Energy is released by a gas when it is compressed
Explanation:
The kinetic molecular theory establishes that gases are composed of molecules. These molecules of gas are far apart from each other hence there is a considerable empty space between the gas molecules. As a result of these empty spaces between gas molecules, it is possible to compress a gas.
Compressibility is defined as a measure of how much the volume of matter decreases under pressure. When a gas is compressed, work is done on the gas and energy is evolved hence the gas heats up.
Convert 812.4 kPa into atm
Answer:
Explanation:
There are a series of unit used to measure PRESSURE. They include millimetre mercury (mmHg), atmospheric pressure (atm), kilopascal etc. These units of measurement are interconvertible i.e. can be changed from one unit to another.
Based on this question asking to convert
1 kilopascal = 0.00986923atm

The actual value for absolute zero in degrees Celsius is −273.15. Use the formula below to determine your percent error for both gas samples.
|experimental value – actual value| x 100
actual value
Please just tell me how to find the experimental value
Answer:
As you noticed, the percent-error formula needs you to use a value in the ... The actual absolute zero is 275C below my coldest recorded value. ... The only way your calculations makes sense is you're trying to calculate how ... Next, I'll interpret "I found that AZ is at -258°C" as "I calculated AZ to be 260 degrees below 2°C".
Explanation:
The experimental error will be 8.95%
Calculating percentage error.The formula used for calculating the percentage error is expressed as:
[tex]\% error=\frac{|exp. \ value - actual \ value|}{actual \ value} \times 100[/tex]
Given the following parameters
Actual value = −273.15 degrees Celcius
Let the experimental value be 300 degrees Celcius (since we are not given)
[tex]\% error=\frac{|300 - 273.15|}{300} \times 100\\\% error=\frac{|26.85|}{300} \times 100\\\% error=8.95\%[/tex]
Hence the experimental error will be 8.95%

Explanation:
A projectile is projected with an initial velocity of 40 m/s at a 45o angle to the horizontal. , calculate the total time travelled.
Answer:
5.77 s
Explanation:
From the question,
The total time travelled by the projectile = Time of flight (T)
T = 2usinθ/g............ Equation 1
Where T = Time of Flight of the projectile, u = Initial velocity, θ = Angle of projection to the horizontal, g = acceleration due to gravity
Given: u = 40 m/s, θ = 45°
Constant: g = 9.8 m/s²
Substitute these values into equation 1
T = 2(40)sin(45°)/9.8
T = 80sin(45°)/9.8
T = 80×0.7071/9.8
T = 5.77 s

1. Cierta muestra fue diluida así: 1 mL MP se agrega 4mL de agua, luego se extrae 0,5 mL y se lleva a 5 mL y de esta última se obtiene 0,2 y se añade 1,3 de diluyente. Calcule la dilución total.
Answer:
1/375
Explanation:
Primero se debe calcular el factor de dilución para cada dilución seriada. Para ello, se divide el volumen de muestra entre el volumen final de la solución diluida.
1) 1 mL en 1 mL + 4 mL = 5 mL
D1 = 1 mL/5 mL = 1/5
2) 0,5 mL en 5 mL
D2 = 0,5 mL/5 mL = 1/10
3) 0,2 mL en 0,2 mL + 1,3 mL = 1,5 mL
D3 = 0,2 mL/1,5 mL = 2/15
La dilución total se calcula como el producto de las diluciones seriadas realizadas:
DT = D1 x D2 x D3 = 1/5 x 1/10 x 2/15 = 1/375
