Which changes in an electric motor will make the motor stronger? select 3 options. using a stronger permanent magnet using a weaker permanent magnet increasing current in the electromagnet decreasing current in the electromagnet increasing the distance between the magnets decreasing the distance between the magnets

Answers

1. Using Strong Permanent. 2. increasing the current. 3. Decreasing the space between Magnets

Explanation:

Brainiest

The changes that make the motor stronger will be using strong permanent magnets, increasing the current, and decreasing the space between magnets.

What is an electric motor?

An electric motor is a mechanism that turns electricity into mechanical energy.

The interaction between the motor's magnetic field and electric current in a wire winding generates force in the form of torque imparted to the motor's shaft in most electric motors.

An electric generator is physically equivalent to an electric motor, but it converts mechanical energy into electrical energy using a reversed flow of power.

When string magnets are used, a strong flux is produced, and the motor becomes more powerful. Internal flux has a significant impact on coil strength.

Increasing current results in greater power. In the same way, shortening the distance between magnets makes the motor stronger by increasing flux and torque.]

Hence the changes that make the motor stronger will be using strong permanent magnets, increasing the current, and decreasing the space between magnets.

Part 1 of 3: Two moles of helium gas initially at 335 K and 0.58 atm are compressed isothermally to 1.44 atm. Find the final volume of the gas. Assume that helium behaves as an ideal gas. The universal gas constant is 8.31451 J/K · mol. Answer in units of m³.

Part 2 of 3: Find the work done by the gas. Answer in units of kJ.

Part 3 of 3: Find the thermal energy transferred. Answer in units of kJ.

Answers

For two moles of helium gas initially at 335 K and 0.58 atm are compressed isothermally to 1.44 atm, The solutions are is mathematically given as

V2=0.03818 m3W=-5.065KJQ =5.065 KJ

What is the final volume of the gas?

Generally, the equation for the Ideal gas law  is mathematically given as

PV=nRT

Therefore

V1=2*8.31451*335/(0.58*1.01325*105)

V1=0.09479 m3

Also

V2=V1*(P1/P2)

V2 =0.09479*(0.58/1.44)

V2=0.03818 m3

b)

W=nRTLn(V2/V1)

W=2*8.31451*335*Ln(0.03818/0.09479)

W=-5.065KJ

c)

In conclusion, Heat energy

In science, a new hypothesis must be (mark all correct answers):

1. falsifiable by experimental testing or observations.

2. completely consistent with all previous laws and theories of science.

3. possible to prove correct.

4. based solely on physical causes.

Answers

Answer:

1, 2, and 3.

Explanation:

Hypotheses must be able to be proven false, otherwise it’s a law. It must be consistent with other theories otherwise it’s not true, and it has to be possible to prove correct, otherwise it’s a theory.

The true statement is "Falsifiable by experimental testing or observations." The correct option is 1.

What is a new hypothesis?

In science, a hypothesis is a proposed explanation or prediction for a phenomenon or set of observations.

A new hypothesis is a fresh idea put forth by a scientist to explain a phenomenon or observation that has not been explained or understood fully by existing scientific theories or hypotheses.

The new hypothesis should be based on previous knowledge and observations, and it should be testable and falsifiable through experiments or observations. Scientists use hypotheses to guide their research and develop theories, which are more comprehensive explanations backed up by multiple lines of evidence.

Therefore, only Option (1) is the correct answer.

Answers

How light travels in space?

A light travels without any medium while on the other hand, a medium is required for sound waves to move from oe place to another. Sound is a mechanical wave that cannot travel through a vacuum.

Describe mathematically how two distinct waves each with wave functions like the one in eq. 2 – call them y1 and y2 – will combine. We call this interaction the principle of superposition.

Answers

The resultant wave of the different wave functions is = y1 + y2

Calculation of the resultant wave functions

The principle of superposition states that two waves moving through the same medium, the resultant value of the wave function is the sum of the different wave functions.

Waves superimpose by adding their disturbances,each disturbance corresponds to a force, and all the forces add.

Therefore, the resultant wave of the different wave functions is the addition of both wave functions which is = y1 + y2.

How does valles marineris differ from the grand canyon?.

Named Valles Marineris, the grand valley extends over 3,000 kilometers long, spans as much as 600 kilometers across, and delves as much as 8 kilometers deep. By comparison, the Earth's Grand Canyon in Arizona, USA is 800 kilometers long, 30 kilometers across, and 1.8 kilometers deep.

A block of mass 3. 0 kg is hung from a spring, causing it to stretch 12 cm at equilibrium, as shown above. The 3. 0 kg block is then replaced by a 4. 0 kg block, and the new block is released from the position shown above, at which the spring is unstretched. How far will the 4. 0 kg block fall before its direction is reversed?.

Answers

Based on the length of the spring and the mass of the block, the distance the 4.0 kg block can fall before a reversal in direction is 32 cm.

How do we arrive at 32cm?

Because energy is conserved, the distance the block can drop can be found as:

Mass x gravity x distance = (1 / 2) x spring constant x distance ²

Spring constant:

= (Mass x gravity)  / distance

= (3 x 9.8) / 12

= 2.45 cm

Distance is:

Mass x gravity x distance = (1 / 2) x spring constant x distance ²

distance = (2 x Mass x gravity) / spring constant

= (2 x 4 x 9.8) / 2.45

= 32 cm

For total internal reflection to take place (i) light must travel from a denser medium to a rarer medium and (ii) the angle of incidence inside the denser medium must be greater

Answer: When a ray of light travels from an optically denser medium to an optically rarer medium and is incident at an angle greater than the critical angle for the two media, the ray totally reflects back into the medium, obeying the laws of reflection.
