Answer:
Mechanical
Explanation:
The tank is at rest. And energy of any substance at rest is known as potential energy.
Now, in forms of energy, potential energy is a type of mechanical energy.
Thus, the correct option is mechanical Energy.
1) A 1,600 kilogram car is also traveling in a straight line. Its momentum is 32,500 kg*m/s. What is the
velocity of the car?
Answer:
v = 20.31 m/s
Explanation:
p = mv -> v = p/m = 32,500 kg*m/s / 1,600 kg = 20.31 m/s

The closer the charged particles, the... the electrostatic force.
Answer:
please give me brain list and follow
Explanation:
Therefore, if the distance between the two charges is doubled, the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value. If the charges come 10 times closer, the size of the force increases by a factor of 100. The size of the force is proportional to the value of each charge.
Plz solve it quick I'm rlly in a hurry
A
Explanation:
When a liquid occupies a smaller volume, it exerts a higher pressure; when it occupies a larger volume, it exerts a lower pressure.
volume= mass÷density
A- 10÷2= 5cm³
B- 20÷1.6= 12.5cm³
C- 30÷1.2= 25cm³
D- 40÷0.7= 57.1cm³
Smallest volume is A, hence largest pressure. As I explained aboveHow do I remove the paint from the carpet. Please I need a real answer.
Answer:
Explanation:
(water based paint)
If the paint stain is still wet, simply blot the spot with a wet paper towel - don’t scrub, just blot.
If the paint stain is dry, use hot water and a little bit of dish detergent. Let the solution sit for a few minutes to soften the paint.
Once the paint is softened, use a knife or pin to scrape the paint stain. Continue to add more solution as you scrape.
If the paint is still not softening, consider using a handheld steamer while you scrape to eventually remove the paint stain from the carpet.
(latex based paint)
Blot the spot to remove as much wet paint as possible – don’t scrub, or you’ll push the paint further down into the carpeting.
Mix a cup of lukewarm water with one teaspoon of dishwashing detergent – just make sure the detergent is mild.
Work from the outside of the paint stain to the inside, gently blotting the affected area.
After letting the area dry completely, follow up by vacuuming.
(oil based paint)
If the paint stain is dry, you’ll want to use a steamer to soften the stain.
Apply steam directly to the stain.
Simultaneously pick at the paint stain with a needle or a pin to try and break it up.
Continue until stain is removed, without damaging fibers.

What are the difference between copper and sodium once you put it to flame?
Answer:
When you burned the skewer tip coated with sodium chloride, you should have seen that the flame was pure yellow-orange (without any blue). This is because when the metal sodium is burned, it makes intense yellow-orange light. ... This is because when the metal copper is burned, it makes bluish-green light.

explain in 2-3 sentences how a genotype determines a phenotype!
Will give b to the best one
Answer:
Genotype can be determined by biological tests. Both the genotype and phenotype sounds similar but have differences. The phenotype is determined by an individual’s genotype and expressed genes or by visible trait, for instance, hair color or type, eye color body shape, and height. We are all unique. Even monozygotic twins, who are genetically identical, always have some variation in the way they look and act. This uniqueness is a result of the interaction between our genetic make-up, inherited from our parents, and environmental influences from the moment we are conceived.

A car advertisement states that a certain car can accelerate from rest to 70 km/h in 7 seconds. Calculate the acceleration of the car.
Answer:
10 km/h
Explanation:
A student walks 3 km in 30 minutes. What is the student's average speed in km/h?
Answer:
6km/hr
Explanation:
3km = 30mins
x(km) = 1hr
1hr = 60 x 60 = 3600secs
30min = 30 x 60 = 1800secs
3 x 3,600/x X 1,800
x = 10,800/1,800
x = 6km/hr
To solve the problem we must know about speed, distance, and time.
What is the relationship between Speed, distance, and Time?
We know that speed, distance, and time all are in a relationship with each other. this relationship can be given as,
[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]
Given to us
A student walks 3 km in 30 minutes.
We know distance can be written as the product of speed and time, therefore,
[tex]\rm Distance = \rm speed \times \rm Time[/tex]
Substituting the values we get,
[tex]\rm 3\ km = Speed \times 0.5\ hour[/tex]
[tex]\rm speed = \dfrac{3\ km}{0.5\ hour}[/tex]
speed = 15 km\h
Hence, the speed of the student is 15 km\hour.

The box is pushed to the right with a force of 40 Newtons and it just begins to move what is the maximum static frictional force
Answer:
The maximum static frictional force is 40N.
Explanation:
When an object of mass M is on a surface with a coefficient of static friction μ, there is a minimum force that you need to apply to the object in order to "break" the coefficient of static friction and be able to move the object (Called the threshold of motion, once the object is moving we have a coefficient of kinetic friction, which is smaller than the one for static friction).
This coefficient defines the maximum static friction force that we can have.
So if we apply a small force and we start to increase it, the static frictional force will be equal to our force until it reaches its maximum, and then we can move the object and now we will have frictional force.
In this case, we know that we apply a force of 40N and the object just starts to move.
Then we can assume that we are just at the point of transition between static frictional force and kinetic frictional force (the threshold of motion), thus, 40 N is the maximum of the static frictional force.
A 19 Ω resistor and a 4 Ω resistor are connected in series to an ideal 18 V battery.
A) Find the current in each resistor.
Answer in units of A.
B) Find the potential difference across the first resistor.
Answer in units of V.
C) Find the potential difference across the second resistor.
Answer in units of V.
Explanation:
First Calculate Total Equivalent Resistance (Series) :
[tex]R_{eq} = r_{1} + r_{2} = 23 \: ohms[/tex]
(A) Current in each resistor :
[tex]I = \frac{V}{R} = 0.78 \: A[/tex]
(Since this is a series connection, the electric current is same through both resistor).
(B) Potential Difference across the first resistor :
[tex]V = IR = 0.78 \times 19 = 14.82 \: V[/tex]
(B) Potential Difference across the second resistor :
[tex]V = IR = 0.78 \times 4 = 3.12 \: V[/tex]
What is due to acids formed when atmospheric and volcanic gases mix with water
Answer:
Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen, and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground.

Ribosomes are like tiny “factories” within cells that do all of the following EXCEPT:
Answer: translate DNA into RNA <3
Explanation:
An RNA polymerase binds to promoters and then breaks down hydrogen bonds between two strands of the DNA and attaches on one of them. A DNA strand is used as a template for a new RNA molecule. In this way, pre-mRNA is made, which becomes mRNA after the introns are removed.
A mRNA molecule enters the ribosomes, located in the cytoplasm. In these organelles, a transfer RNA attaches to a mRNA and the process of translation begins. The final product is a polypeptide chain.

Question:
To increase the energy efficiency of their home, a Colorado family
installed a solar panel on its roof. They want to add another solar panel to
increase their ability to store energy for the winter. What happens to the
current (1) when they add another solar panel (V)? *
Answer: When they add another solar panel, there will be INCREASE in current.
Explanation:
The movement of electric charges through a conductor is known as CURRENT (I) and is measured in ampere(A). Voltage is defined as the potential energy that moved charged particles. While resistance is the opposition to the flow of electric charges.
The increase in current abides by the rules of ohm's law which states that the electric current in a given metallic conductor is directly proportional to the potential difference (Voltage) applied between its ends, provided that the temperature of the conductor and other physical factors remain constant. This relationship simply means that increase in voltage will lead to increase in current in a circuit.This can be represented by an equation below:
V= IR
Where V = Voltage
I = Current
R = Resistance
Since increase in voltage lead to increase in current as seen in Ohm's law, therefore the addition of extra solar panels ( voltage) will lead to increase in current out put during winter.
