Explanation:

The reason why motors are designed so that the polarity of the electromagnet constantly flips.is

C. so the electromagnet will continuously turn

The reason motors are designed so that the polarity of the electromagnet constantly flips is to continuously turn the electromagnet. This allows the motor to rotate continuously, rather than becoming stuck in one position.

The flipping of the polarity causes the electromagnet to attract and repel from the permanent magnets, creating a rotating motion.

Therefore, the correct answer is C.

Answer:

Los coeficientes de fricción estática y cinética son [tex]\frac{1}{15}[/tex] y [tex]\frac{1}{60}[/tex], respectivamente.

Explanation:

Por la Primera Ley de Newton, sabemos que la fuerza externa debe tener igual magnitud y dirección contraria a la fuerza de reacción (fricción). Puesto que el trineo se mueve sobre una superficie horizontal, la magnitud de la fuerza normal es la del peso ([tex]W[/tex]), en newtons. El coeficiente de fricción estática ([tex]\mu_{s}[/tex]), sin unidad, es la razón de la fuerza de fricción justo antes del movimiento inminente ([tex]F[/tex]), en newtons, a la fuerza normal ([tex]N[/tex]), en newtons:

[tex]\mu_{s} = \frac{F}{W}[/tex] (1)

Si sabemos que [tex]F = 40\,N[/tex] y [tex]W = 600\,N[/tex], entonces el coeficiente de fricción estática es:

[tex]\mu_{s} = \frac{F}{W}[/tex]

[tex]\mu_{s} = \frac{40\,N}{600\,N}[/tex]

[tex]\mu_{s} = \frac{1}{15}[/tex]

El coeficiente de fricción cinética ([tex]\mu_{k}[/tex]), sin unidad, es la razón de la fuerza de fricción experimentada por el trineo en movimiento ([tex]F[/tex]), en newtons, a la fuerza normal:

[tex]\mu_{k} = \frac{F}{W}[/tex] (2)

Si sabemos que [tex]F = 10\,N[/tex] y [tex]W = 600\,N[/tex], entonces el coeficiente de fricción cinética es:

[tex]\mu_{k} = \frac{F}{W}[/tex]

[tex]\mu_{k} = \frac{10\,N}{600\,N}[/tex]

[tex]\mu_{k} = \frac{1}{60}[/tex]

Los coeficientes de fricción estática y cinética son [tex]\frac{1}{15}[/tex] y [tex]\frac{1}{60}[/tex], respectivamente.

Answer:

Voltage = 9.6 Volts

Explanation:

Given the following data;

Resistance = 24Ω

Current = 0.4A

To find the voltage of the battery;

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

[tex] V = current * resistance [/tex]

Substituting into the formula, we have;

Voltage = 0.4 * 24

Voltage = 9.6 Volts

Therefore, the battery voltage must be 9.6 volts

Explanation:n general, a screw can hold 80-100 pounds. Several factors can impact on the amount of weight the screw can hold. This includes the length of the screw, the type of thread, the quality of the screw, the way it was inserted, and the type of forces that will be acting on it.

Answer:

its lost 91

Explanation:

Answer:

The show with 20 N force will accelerate more than the show with 10 N force, because 20 N force is greater than 10 N force.

Explanation:

From Newton's second law of motion, acceleration is the ratio of applied to mass of the object.

[tex]acceleration = \frac{Force}{mass}[/tex]

Acceleration is directly proportional to an applied force. At a constant mass, acceleration increases with an increase in the applied force.

Therefore, the show with 20 N force will accelerate more than the show with 10 N force, because 20 N force is greater than 10 N force.

Explanation:

Answer:

6.0cm

Explanation:

Given

focal length = 15.0cm

object distance = 10.0cm

Required

Image distance v

Using the formula

1/f = 1/u + 1/v

1/15 = 1/10+1/v

1/v = 1/15 + 1/10

1/v = 2+3/30

1/v = 5/30

v = 30/5

v = 6.0cm

Hence the image distance is 6.0cm

The one that is not a way in which life is dependent on photosynthesis is that helping in cure of diseases. The correct option is C.

Photosynthesis is a technique that plants as well as other lifeforms use to transform light energy into chemical energy that can then be released to fuel the organism's activities via cellular respiration.

Photosynthesis' primary function is to convert solar energy into chemical energy and then store that chemical energy for later use. This process powers the majority of the planet's living systems.

Photosynthesis is essential to all living things because it is the primary source of oxygen in the atmosphere.

Without photosynthetic activity, the carbon cycle would not have been possible, oxygen-requiring life would perish, and plants would perish.

Due to photosynthesis, the organisms breathe in the oxygen, sugar is used as a food, and also helps to lower down global warming.

Thus, the correct option is C.

Explanation:

velocity = wavelength × frequency => v= f1 × λ => f1 = v/ λ

λ = stays the same

v = doubles

f2/f1= 2vλ/ vλ = 2

f2 = 2f1

therefore frequency is doubled

Explanation:

If a wave is travelling at 3000 m/s and has a wavelength of 1 meter the frequency of the wave would be 3000 Hz and the time period of the wave would be 3.33×10⁻⁴ seconds.

It can be defined as the number of cycles completed per second. It is represented in hertz and inversely proportional to the wavelength.

Frequency = 1/T

As given in the problem If a wave is travelling at 3000 m/s and has a wavelength of 1 meter,

Explanation:

Bromine contains 35 protons, 36 electrons, and 45 neutrons. The mass number of Bromine is  80. The ion charge of bromine is +7. "Br" is the symbol of Bromine.

Discussion about bromine:

Two chemists, Carl Jacob Löwig and Antoine Balard, independently discovered bromine in 1825 and 1826, respectively.

The chemical element bromine has the atomic number 35 and the symbol Br. It is the 3rd halogen, and at room temperature, it is a flammable red-brown liquid that easily evaporates to create a vapor of a similar color. Its characteristics fall in between those of iodine and chlorine.

Due to its high reactivity, elemental bromine does not naturally occur in its free form but rather as crystals minerals halide salts that are colorless and soluble, similar to table salt. Although the bromide ion (Br) is relatively uncommon in the Earth's mantle, its great solubility has led to its buildup in the seas.
