Answers

Answer:

  W = 3.75 kJ

Explanation:

Power is defined by the relational

          P = W / t

          W = P t

the yield is 25% = 0.25

           W = 0.25 Wo

           W = 0.25 250 60

           W = 3750 J

Henry mixed salt and water together in a cup until he observed a clear solution. He measured the mass of the solution. Then he placed the cup outside for several sunny days during the summer. After a week, he observed that only solid salt remained in the cup and the mass had decreased. Henry concluded that a physical and chemical change occurred in this investigation.

Which statements correctly defend or dispute his conclusion?

He is correct. Dissolving salt in water is a physical change, but evaporating the water is a chemical change. Formation of a solid is evidence that a chemical change occurred.
He is correct. Evaporation is a physical change, but dissolving salt in water is a chemical change. The change in mass is evidence that a chemical change occurred.
He is incorrect. Dissolving salt in water and evaporation of the water are both physical changes. The reappearance of salt is evidence that the change was reversible by a physical change, so it could not be a chemical change.

Answers

Answer:

But where are the graphs

Coulomb's Law describes the relationship between electromagnetic force and the distance between charges.

What is the relationship between electromagnetic force and the distance between charges?

The relationship between electromagnetic force and the distance between charges is described by Coulomb's Law, which states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Mathematically, Coulomb's Law is expressed as:

F = k  (q₁x q₂) / r²

where F is the electromagnetic force, q1 and q2 are the charges, r is the distance between the charges, and k is the Coulomb constant.

This means that as the distance between two charges increases, the force between them decreases, and as the distance decreases, the force increases. The relationship between force and distance is inverse square, which means that the force decreases rapidly as the distance increases.

1. Mineral in the earth's crust exists naturally in form of solid elements or compounds *
True
False​

Answers

Answer:

True

Explanation:

Minerals can be defined as any form of naturally occurring, inorganic solid substance characterized by a crystal structure. Also, minerals are homogeneous in nature with a defined chemical composition and characterized by a crystal structure comprising of ions, atoms, or molecules in an orderly arrangement.

Generally, molecules attach on the inside of a mineral to give it shape. Therefore, the molecule of a mineral is a crystal three-dimensional regular structure (arrangement) of chemical particles that are bonded together and determines its shape.

Furthermore, the chemical composition (property) of a mineral reflect the presence and arrangement of atoms in each.

Due to the fact that these molecules are structurally arranged (ordered) and are repeated by different symmetrical and translational operations, they determine the shape of minerals. Some examples of minerals are iron, copper, aluminum, tin, coal, quartz, feldspar, mica, etc.

Additionally, inorganic-crystalline solid substances which are found naturally within earth are referred to as minerals.

In conclusion, a mineral in the earth's crust exists naturally in form of solid elements or compounds.

Jerome has a tow truck, and he is in charge of moving several vehicles for the city. He wants to explain to his niece how towing vehicles relates to Newton's second law. Which statement should he use?

Answers

Answer:

Force = mass x acceleration

Explanation:

According to the Newton's second law, the net force acting on the object is proportional to the rate of change of momentum of the body.

So, Force is given by

F = m a

where, F is the force, m is the mass and a is the acceleration.

when the mass is more, the acceleration is less as the force applied by the truck is same.

A resistor of 500Ω and one of 2000Ω are placed in series with a 60V supply. What will be the reading on a voltmeter of internal resistance 2000Ω when placed across (i) 500Ω resistor and (ii) 2000Ω resistor?

Answers

Answer: 10 V, 40 V

Explanation:

Given

Resistors are [tex]500\Omega[/tex] and [tex]2000\Omega[/tex]

Power supply [tex]V=60\ V[/tex]

Voltmeter internal resistance [tex]r=2000\ \Omega[/tex]

When it connected around [tex]500\Omega[/tex] resistance, effective resistance becomes

[tex]\Rightarrow \dfrac{1}{R}=\dfrac{1}{500}+\dfrac{1}{2000}\\\\\Rightarrow R=\dfrac{2000}{5}\\\\\Rightarrow R=400\ \Omega[/tex]

Total resistance in series [tex]R_{net}=2400\ \Omega[/tex]

Current in circuit

[tex]I=\dfrac{60}{2400}=\dfrac{1}{40}\ A[/tex]

Voltage around [tex]500\Omega[/tex] resistance is

[tex]V=\dfrac{1}{40}\times 400\\\\V=10\ V[/tex]

(B) when voltmeter is connected around [tex]2000\Omega[/tex]  resistor

Net resistance around it

[tex]\Rightarrow \dfrac{1}{R}=\dfrac{1}{2000}+\dfrac{1}{2000}\\\\\Rightarrow R=1000\ \Omega[/tex]

Total resistance [tex]R_{net}=1500\ \Omega[/tex]

Current in circuit

[tex]I=\dfrac{60}{1500}=\dfrac{1}{25}\ A[/tex]

Voltage around [tex]2000\Omega[/tex] resistor

[tex]V=\dfrac{1}{25}\times 1000\\\\V=40\ V[/tex]

how can you reduce output voltage to 6v in transformers if the input voltage is 240v​

Answers

Answer:

[tex]N_P = 40\ N_S[/tex]

To reduce the output voltage to 6v in transformers if the input voltage is 240v​, we need to have 40 times as many turns in the primary coil as there are in the secondary coil.

Explanation:

The change in voltage of a transformer depends upon the turns ratio of the transformer between secondary and primary coil. Following formula can be used to determine the turns ratio in this case:

[tex]\frac{N_P}{N_S} = \frac{V_P}{V_S} \\\\[/tex]

where,

[tex]N_P[/tex] = No. of turns in the primary coil

[tex]N_S[/tex] = No. of turns in the secondary coil

[tex]V_P[/tex] = voltage in the primary coil = 240 V

[tex]V_S[/tex] = voltage in the secondary coil = 6 V

Therefore,

[tex]\frac{N_P}{N_S} = \frac{240\ V}{6\ V} \\\\N_P = 40\ N_S[/tex]

To reduce the output voltage to 6v in transformers if the input voltage is 240v​, we need to have 40 times as many turns in the primary coil as there are in the secondary coil.
