This graph provides data on the amount of water needed to grow four different crops, each used to produce ethanol, a fuel. For each crop, the data shows how many liters of water are needed to produce one liter of ethanol fuel. Which of the following would require using the most water? *
Producing 100 L of ethanol from sugar cane
Producing 200 L of ethanol from sugar beet
Producing 300 L of ethanol from potatoes
Producing 400 L of ethanol from corn
Answer:
Producing 300 L of ethanol from potatoes
Explanation:
From the diagram, one liter of ethanol production from sugar cane requires 2000 liters of water. Hence, in order to produce 100 L of ethanol from sugar cane, 2000 x 100 = 200,000 L of water.
1000 liters of water is needed to produce 1 liter of ethanol from sugar beet. Hence, 200 x 1000 = 200,000 L of water will be needed to produce 200 liters of ethanol.
1000 liters of water is also required to produce 1 liter of ethanol from potatoes, hence, 300 x 1000 = 300,000 L of water would be required to produce 300 L of ethanol from the same material
About 500 liters of water is required to produce 1 liter of ethanol from corn, hence, 400 x 500 = 200,000 L of water would be needed to produce 400 L of ethanol from corn.
In conclusion, producing 300 L of ethanol from potatoes would require using the most water among all the options.

Which of the following provides the best summary of the process of natural
selection?
A. Population sizes increase with every generation.
B. Individuals pass on their best traits to their offspring.
C. Mutations help an individual survive and reproduce.
D. Well-adapted individuals survive and reproduce.
Answer:
B. Individuals pass on their best traits to their offspring.
Explanation:
because genes are always passed from parents to offspring.
The best summary of the process of natural selection is Individuals pass on their best traits to their offspring. Hence, the correct option is B.
What is the theory of Natural selection?The theory of natural selection gives the mechanism of evolution. It defines the method of different survival and reproduction of individuals due to differences in phenotype.
The theory of natural selection was proposed by Charles Darwin as a way of adaptation and speciation. The variations occur in organisms by random mutations occurring in the genome of individual organisms and this change in mutations may inherit in offspring.
Organisms that are more adapted to the environment are more likely to survive and pass on the genes to future generations. This process cause changes to the generations and diverged over time.
The organisms produce more offspring that are able to survive in the environment. The four factors of natural selection are Variations, Inheritance, Selection, and time.
Thus, the best summary of the process of natural selection is individuals pass on their best traits to their offspring. Hence, the ideal solution is option B.

What is the kinetic energy of a bicylcle with a mass of 15 kg traveling at a velocity of 3 m/s?
KE = 0.5 x mv^2
Kinetic energy equals 1/2 times mass times velocity squared.
Mass = 15kg
Velocity = 3m/s
Plug it into the formula.
KE = 0.5 x 15(3^2)
KE = 0.5 x 15(9)
Multiply the mass and velocity squared.
KE = 0.5 x 135
Then, multiply the result by 1/2 or 0.5
KE = 67.5
The kinetic energy of a bicycle that has a mass of 15kg and travels at 3m/s is 67.5J.
Answer:
67.5 J
Explanation:
Kinetic energy can be found using the following formula.
[tex]KE=\frac{1}{2}mv^2[/tex]
where m is the mass in kilograms and v is the velocity in m/s.
We know the bike has a mass of 15 kilograms. We also know the velocity is 3 m/s. Therefore, we can substitute 15 for m and 3 for v
[tex]KE=\frac{1}{2}*15*3^2[/tex]
Evaluate the exponent first. 3^2 is the same as 3*3, which is equal to 9.
[tex]KE=\frac{1}{2} *15*9[/tex]
Multiply 15 and 9.
[tex]KE=\frac{1}{2} *135[/tex]
Multiply 1/2 and 135
[tex]KE=67.5[/tex]
Add appropriate units. Kinetic energy uses Joules or J as the units.
[tex]KE= 67.5 Joules[/tex]
The kinetic energy of the bike is 67.5 Joules
Determine What is the efficiency of a machine whose work output is 4 joules, and whose work input is 10 joules?
Answer:
The efficiency of the machine is 40 %.
Explanation:
We have,
Output work by the machine is 4 joules and the input work is 10 joules.
It is required to find the efficiency of a machine. The efficiency of a machine is given by the ratio of output work to the input work. It is given as :
[tex]\eta=\dfrac{4}{10}\times 100\\\\\eta=40\%[/tex]
So, the efficiency of the machine is 40 %.

It lasted two hours or 120 minutes, it would be smart to say that he was riding up it during the interval 20-60min and riding down it during the interval 60-80min. This is an assumption made because of his speed, when going up a hill our speed is slower while when riding down it, you gain a lot of speed.

Which term is defined as the force applied to the object divided by the mass of the object?
speed
velocity
mass
acceleration
Answer:
acceleration
Explanation:
From the question: "FORCE... divided by the MASS..." is translated to a math equation as "F / m", where "F" is the force and "m" is the mass.
Now, the second Newton's law says "F = m . a ", where a is acceleration.
If you move m to the left side, clearly you have "F / m", and "a" is alone to the right. Math equation:
a = F / m
acceleration = force / mass

A pendulum reaches a height of 0.3 m at the top of its swing. If the
bob has a mass of 5 kg, what is the potential energy at the top of its
swing?
Select one:
14.7)
7.35 J
0.45 J
1.5 J
Answer: A
Potential energy = 14.7 J
Explanation:
Given that the
Mass M = 5 kg
Height h = 0.3 m
Let us take acceleration due to gravity g = 9.81 m/s^2
Potential energy = mgh
Substitute all the parameters into the formula above
P.E = 5 × 9.81 × 0.3
P.E = 14.715 J
P.E = 14.7 J approximately
The correct option is therefore A

B.
The space contains an electric field.
C.
The space has a charge opposite to the particle's.
D.

Answer: A.
The space contains a magnetic field
Explanation:
A charged particle is surrounded by electric field and exerts force on other charges in the field, attracting or repelling them.
But a charged particles in a magnetic field can escape into infinity without ever stopping due to magnetic force. We can therefore conclude that the space contains a magnetic field

why is it dangerous to connect a battery to itself. what is the term used to describe that
what is mass times acceleration?
Answer:
Force
Explanation:
The mass of an object is the quantity of matter it contains. It is measured in kilograms.
Acceleration is the ratio of the change in the velocity of an object to the change in time. It is measured in m/[tex]s^{2}[/tex].
When the mass of an object is multiplied with its acceleration, this gives the average force applied on the object. As force is defined as agent that can change the state of an object.
i.e F = m × a
where F is the force, m is the mass of the object and a its acceleration.
The two major classes of force are; contact force and field force.

A. A possible unit for density is grams.
B. Liquid gold is denser than solid gold.
C. Density is found by multiplying mass
and volume.
D. Density is independent of the
amount of the sample.
Answer:
Density is independent of the
amount of the sample. (D)
Explanation:
Because density is an intrinsic property of matter.
hope it helps!
Answer:
D. Density is independent of the
amount of the sample.
Explanation:
Density is expressed in units of mass per volume, such as g/mL or kg/m3. Because the density of a substance does not depend on the amount of substance present, density is an “intensive property”. To measure the density of a sample of material, both the mass and volume of the sample must be determined.
