A motor with an operating resistance of 24Ω is connected in a circuit witn 0.4A of current. The battery voltage must be volts
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
What is the mass number, symbol, and charge of an ion that contains 35 protons, 45 neutrons and 36 electrons?
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.

Bryce has selected a major in political science but has a little interest in understanding public relations
Hi, you've asked an incomplete question. However, I assumed you want additional comments about this scenario.
Explanation:
Note, the term Major as used in academic contexts refers to a person's preferred interest or specialization at college or university.
Hence, the statement about Bryce appears to be contradictory, since we are told he "has little interest in understanding public relations".

what is the conclusion of coin and feather experiment?
Answer:
So the conclusion is that in presence of air net force acting downward reduces for feather and hence falls slower than coin. But in absence of air resistance, net downward force is just equal to force due to gravity which is same for both coin and feather and hence they fall down at the same rate.

An electromagnet is a device that uses an electric current to produce a magnetic field.
Electromagnets are typically composed of a piece of metal wrapped with wire and connected to a battery. The battery provides the electric current, and the loops or coils of wire enhance the magnetic field. The more loops there are, the stronger the magnetic field.
When electric current flows through the electromagnet, the metal core becomes magnetized, so it possesses a north pole and a south pole.
Motors place electromagnets inside of permanent magnets as shown below.
However, motors are designed so that the polarity of the electromagnet constantly flips. That is, the north pole becomes the south pole, and the south pole becomes the north pole, every time the electromagnet turns 180 degrees.
Why is it designed this way?
A.
to conserve the energy in the battery
B.
to constantly polarize the field magnet
C.
so the electromagnet will continuously turn
D.
so the magnetic field will get stronger
The reason why motors are designed so that the polarity of the electromagnet constantly flips.is
C. so the electromagnet will continuously turn
Why is motor designed that wayThe 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.

If you were to throw one show with a force of 20 Newtons and the other with a force of 10 Newtons, which would accelerate more? Why?
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.

If the wavelength of a wave stays the same and the speed doubles, what happens to the frequency of the wave?
Explanation:
velocity = wavelength × frequency => v= f1 × λ => f1 = v/ λ
λ = stays the same
v = doubles
2v = f2 × λ
2v/λ = f2
now ,
f2/f1= 2vλ/ vλ = 2
f2 = 2f1
therefore frequency is doubled

1.-Una fuerza horizontal de 40 N es apenas suficiente para poner en marcha un trineo de 600 N sobre nieve compacta. Después de empezar el movimiento se requieren tan solo 10 N para mantener el trineo a rapidez constante. Halle los coeficientes de fricción estática y cinética
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.
