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.

Answers

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]

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

Answers

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.

The closer the charged particles, the... the electrostatic force.

Answers

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.

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

Answers

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

explain in 2-3 sentences how a genotype determines a phenotype!
Will give b to the best one

Answers

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?

Answers

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.

Oxygen Supply in Submarines Nuclear submarines can stay under water nearly indefinitely because they can produce their own oxygen by electrolysis of water.


How many liters of O2 at 298 K and 1.00 bar are produced in 1.00 hr in an electrolytic cell operating at a current of 0.0200 A?

Answers

Answer:

1.865 * 10^-4 L

Explanation:

The equation of the reaction is:

4OH^-(aq) ----->2H2O(l) + O2(g) + 4e

Since one mole of oxygen which occupies 22.4 L is produced in the electrolysis of water by 4 Faraday of electricity as shown in the equation above;

Then;

4 * 96500 C liberates 22.4 L of oxygen

60 * 60 * 0.0200 C will liberate 60 * 60 * 0.0200 *  22.4/4 * 96500

= 1.865 * 10^-4 L

how does Lightning occur

I hope this helped!
Lightning is an electrical dis.charge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds. This heat causes surrounding air to rapidly expand and vibrate, which creates the pealing thunder we hear a short time after seeing a lightning flash.

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?

Answers

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.

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)

Answers

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
