Answer:
Because fluid pressure increases with depth, there is more fluid pressure___outside__ of a submerged object than on the _inside___
Explanation:
As the object is submerged means that it is under water and not on the surface. It tells that water pressure exerting on the object from the outside is higher than inside which is why the object is submerged.
In the other case, the object will not remain submerged if its internal pressure is high, it will float on water.

Definition of an electrically charged object
Answer:
Electric charge, basic property of matter carried by some elementary particles that governs how the particles are affected by an electric or magnetic field. Electric charge, which can be positive or negative, occurs in discrete natural units and is neither created nor destroyed.
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.

How do you calculate the weight of a body from its mass?
Answer:
W = mg
Explanation:
The formula of Weight for given mass is
[tex]\large\boxed{\fcolorbox{blue}{yellow}{W = mg}}[/tex]
where,
m = mass of the body
g = accelaration due to gravity
For Example:
Q.) A body has mass 10 kg then fine it's weight
A.)
m = 10kg
g = 10m/s²
.°. W = mg
= 10 × 10
W = 100N
Thus, The weight of a body from its mass can be calculated by W = mg.

Why does food need to be broken down (made into chyme) in the stomach (Think about the next step in digestion)
Will mark braniest if correct and has clear explanation
Answer: Carbohydrates , proteins and lipids are large molecules that are needed by the body for growth, repair and metabolism . They are found in our food. These molecules are too large to pass from the intestine into the blood, so digestive enzymes break them down into smaller molecules.
Explanation:
Answer:
Digestion is the mechanical and chemical break down of food into small organic fragments. It is important to break down macromolecules into smaller fragments that are of suitable size for absorption across the digestive epithelium. Large, complex molecules of proteins, polysaccharides, and lipids must be reduced to simpler particles such as simple sugar before they can be absorbed by the digestive epithelial cells. Different organs play specific roles in the digestive process. The animal diet needs carbohydrates, protein, and fat, as well as vitamins and inorganic components for nutritional balance. How each of these components is digested is discussed in the following sections

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 aboveQuestion:
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.
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.

calculate speed and velocity of the following. the race car was moving for 3.7 hours and during that time it traveled a distance of 500 miles south. what is the speed the car was travelling?
Answer:
v = 135.13 mph
Explanation:
Given that,
The race car was moving for 3.7 hours and during that time it traveled a distance of 500 miles south.
We need to find the speed of the car.
We know that,
Speed = distance/time
So,
[tex]v=\dfrac{500\ miles}{3.7\ h}\\\\v=135.13\ mph[/tex]
So, the speed of the car is equal to 135.13 mph.
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.

10000 J of heat energy is absorbed per cycle by a diesel engine that is 11% efficient. How much energy does it expel to the environment per cycle? (J)
Answer:
8900 J
Explanation:
Let heat absorbed be Q1 and heat rejected be Q2.
Q1 = 1000 J, efficiency η = 11% = 0.11
Then, Efficiency of engine can be found be using the following formula,
[tex]\eta = \frac{Q_1-Q_2}{Q_1}[/tex]
⇒ [tex]0.11 = \frac{10000-Q_2}{10000}\\Q_2 = 10000- 1100= 8900 J[/tex]
Therefore, energy does it expels to the environment per cycle = 8900 J
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.
