If the needle in the galvanometer is going up, what can you conclude about the motion of the magnet in the diagram?

It is not moving.

It must be moving left.

It must be moving right.

It is being moved in an unknown direction.

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

if I am right plz give me a brainliest

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.

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.

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.

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.

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.

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.

Answer:

v = 20.31 m/s

Explanation:

p = mv -> v = p/m = 32,500 kg*m/s / 1,600 kg = 20.31 m/s

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]

Answer:Acids and bases cannot mix together. Acids and bases will neutralize each other. Acids, but not bases, can change the pH of a solution. Acids donate hydroxide ions (OH–); bases donate hydrogen ions (H+)

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

Answer:

The closer and bigger the star, the larger the star appears.

Explanation:

Since the sun is closer to us it shows up way larger than other stars in our galaxy.

Have a great day.

Answer:

It is the closest star to us. other bigger stars may seem small, but that is because they are far away. The more closer an object is, the smaller it seems to be.

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.

Answer: C, E, and D is incorrect

Explanation:

C is wrong because the arrows are going inside but they should be negative not positive. E is wrong because it should be positive not negative since the arrows are going outward. D is wrong because there are more arrows in the right side instead it is suppose to be on all sideS

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.
