A speaker draws 2 amps of current when it is connected to a 16 volt source. What is the resistance of the speaker?

32 ohms

32 amps

8 amps

8 ohms

Answers

Resistance = Voltage / Current
Resistance = 16 / 2
Resistance = 8

Answer : 8 ohms

(it wouldn't be 8 amps because the question is asking for the resistance, and resistance is measured in ohms)

The resistance of the speaker is calculated using Ohm's law and the provided values of 16 volts and 2 amps, resulting in a resistance of 8 ohms. The correct answer is d) 8 ohms.

The resistance of the speaker can be found using Ohm's law, which states that voltage (V) is equal to the current (I) times the resistance (R), or V = IR.

Since we know that the speaker draws 2 amps of current and is connected to a 16-volt source, we can rearrange Ohm's law to solve for resistance (R) as follows: R = V / I. By plugging in the given values we have R = 16 V / 2 A, which equals 8 ohms. Therefore, the resistance of the speaker is 8 ohms.

Find the total translational kinetic energy of 1.5 l of oxygen gas held at a temperature of 0°c and a pressure of 0.8 atm.

Answers

The ideal gas law states that:
[tex]pV=nRT[/tex]
where
p is the gas pressure
V is its volume
n is the number of moles
R is the gas constant
T is the absolute temperature

However, this equation can be also rewritten as
[tex]PV= \frac{2}{3}NK [/tex] (1)
where
N is the number of molecules in the gas, and K is the average kinetic energy of the molecules. Therefore, NK represents the total kinetic translational energy of the gas.

For the gas in our problem,
[tex]p=0.8 atm = 8.08 \cdot 10^4 Pa[/tex]
[tex]V=1.5 L =1.5 \cdot 10^{-3} m^3[/tex]
So, the total translational kinetic energy of the gas is (using eq.(1) )
[tex]NK= \frac{3}{2}pV= \frac{3}{2}(8.08 \cdot 10^4 Pa)(1.5 \cdot 10^{-3} m^3)=181.8 J [/tex]

Final answer:

To calculate the total translational kinetic energy of 1.5 liters of oxygen gas at 0°C and 0.8 atm, use the ideal gas law to find the number of moles and then apply the translational kinetic energy equation (KEtrans = (3/2)nRT).

Explanation:

To find the total translational kinetic energy (KEtrans) of 1.5 liters of oxygen gas at 0°C (273 K) and 0.8 atm, we can use the ideal gas law and the equipartition theorem. The ideal gas law PV = nRT can give us the number of moles of oxygen gas when rearranged to n = PV/RT. Here, P is the pressure, V is the volume, R is the ideal gas constant, and T is the temperature.

Once the moles (n) are calculated, the translational kinetic energy per mole of a gas can be found using the equation KEtrans = (3/2)nRT, where n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin. By substituting the values into the equation, we can find the total translational kinetic energy of the gas sample.

Answers

Answer:

Explanation:

edge

The nuclear binding energy of an atom that has a mass defect of 1.643×10⁻²⁸ kg is 4.93 10⁻²⁰ J . Hence option B is correct.

What is Binding Energy ?

The binding energy is the amount of energy necessary to detach a particle from a particle system or to scatter all of the system's particles. Subatomic particles in atomic nuclei, electrons bound to nuclei in atoms, and atoms and ions linked together in crystals are all examples of binding energy.

Nuclear binding energy is the energy necessary to entirely split an atomic nucleus into its component protons and neutrons, or the energy freed by merging individual protons and neutrons into a single nucleus. The hydrogen-2 nucleus, which consists of one proton and one neutron, may be entirely separated by delivering 2.23 million electron volts (MeV) of energy. In contrast, when a neutron and a proton move slowly, When a slowly moving neutron and proton unite to produce a hydrogen-2 nucleus, 2.23 MeV of gamma radiation is released. The total mass of the bound particles is smaller than the sum of the masses of the component particles by an amount equal to the binding energy (as represented in Einstein's mass-energy equation).

In this problem,

The mass defect is Δm = 1.643×10⁻²⁸ kg

Speed of light c = 3×10⁸ m/s

Nuclear binding energy,

B.E. = Δmc²

B.E. = 1.643×10⁻²⁸ kg × 3×10⁸ m/s

B.E. = 4.929×10⁻²⁰ ≅ 4.93 10⁻²⁰ J

Hence option B is correct.

If a 100N weight sits in an express elevator what will be the weight when the elevator is traveling at a constant speed

Answers

This is a "trick" question.

If the elevator is traveling at constant speed, it means it is at rest. This means anything inside the elevator traveling at constant speed, weights the same as in an elevator not moving -also at rest-.

So the 100N weight's weight doesn't change in an elevator traveling at constant speed.

Final answer:

The weight of the 100N weight will remain the same when the elevator is travelling at a constant speed.

Explanation:

When the elevator is travelling at a constant speed, the weight of the 100N weight will remain the same. The weight of an object is the force exerted on it due to gravity, and this force does not change regardless of the elevator's speed or direction. So, the weight of the object will still be 100N.

Answers

The correct order is the following:

1) An atom fission
2) Neutrons are produced
3) Neutrons find other atoms
4) Many atoms fission

This is the description of a fission chain reaction: initially, the reaction starts with the fission of an atom with unstable nucleus. In the fission, neutrons are produced, and they travel through the surrounding medium. Eventually, they meet other atoms and they are captured by their nuclei: the nuclei become unstable and they undergo fission as well.

If Star A and Star B have the same absolute magnitude, but Star A is brighter, what does that tell us?

Answers

We can conclude that star A is closer to us than star B.

In fact, the absolute magnitude gives a measure of the brightness of the star, if all the stars are placed at the same distance from Earth. So, it's a measure of the absolute luminosity of the star, indipendently from its distance from us: since the two stars have same absolute magnitude, it means that if they were at same distance from Earth, they would appear with same luminosity. Instead, we see star A brighter than star B, and the only explanation is that star A is closer to Earth than star B (the closer the star A, the brigther it is)

Jody has a mass of 50 kilograms what is his weight on earth

Answers

Final answer:

Jody's weight on Earth is calculated by multiplying his mass (50 kg) by Earth's standard gravity (9.81 m/s^2), which equals 490.5 newtons.

Explanation:

When calculating the weight of an object on Earth, we need to account for the force of gravity acting upon the object's mass. The standard acceleration due to gravity on Earth is approximately 9.81 meters per second squared (m/s2). To find Jody's weight, we multiply his mass by the acceleration due to gravity:

Weight = Mass times Earth's gravity

Weight = 50 kg times 9.81 m/s2

Weight = 490.5 N (newtons)

Therefore, on Earth, Jody weighs 490.5 newtons.

The inventor of a new machine claims that its actual mechanical advantage is 4. Literature on the machine reports its input distance is 81 meters and its output distance is 27 meters. Find the machine's ideal mechanical advantage, and determine whether the developer's claim could be true.

Answers

Final answer:

The ideal mechanical advantage (IMA) of the machine is 3. The developer's claim of an actual mechanical advantage (AMA) of 4 is higher than the calculated IMA, suggesting that some energy is lost to friction. Therefore, the claim is not true.

Explanation:

The ideal mechanical advantage (IMA) of a machine is calculated by dividing the input distance by the output distance. In this case, the input distance is 81 meters and the output distance is 27 meters. Therefore, the IMA of the machine is 81/27 = 3.

The developer's claim of an actual mechanical advantage (AMA) of 4 is higher than the calculated IMA of 3. This suggests that some energy is lost to friction in the machine, reducing its efficiency and resulting in a lower AMA. Therefore, based on the calculated IMA, the developer's claim could not be true.

When ultraviolet light with a wavelength of 400 nm falls on a certain metal surface, the maximum kinetic energy of the emitted photoelectrons is measured to be 1.10 eV .
What is the maximum kinetic energy of the photoelectrons when light of wavelength 285 nm falls on the same surface?

Answers

In the photoelectric effect, the energy of the incoming photon is used partially to extract the photoelectron from the metal (work function) and the rest is converted into kinetic energy of the photoelectrons:
[tex]hf=\phi + K_{max}[/tex] (1)
where
h is the Planck constant
f is the photon frequency
[tex]\phi[/tex] is the work function
[tex]K_{max}[/tex] is the maximum kinetic energy of the photoelectrons

In the first part of the problem, we have light with wavelength [tex]\lambda=400 nm=400 \cdot 10^{-9} m[/tex], so the photons have frequency
[tex]f= \frac{c}{\lambda}= \frac{3 \cdot 10^8 m/s}{400 \cdot 10^{-9} m}=7.5 \cdot 10^{14}Hz [/tex]
where c is the speed of light; and therefore the energy of the photons is
[tex]E=hf=(6.6 \cdot 10^{-34}Js)(7.5 \cdot 10^{14} Hz)=5.0 \cdot 10^{-19} J[/tex]
Converted into electronvolts ([tex]1 eV= 1.6 \cdot 10^{-19} J[/tex]):
[tex]E=5.0 \cdot 10^{-19} J =3.12 eV[/tex]

The maximum kinetic energy of the photoelectrons in this case is
[tex]K_{max}=1.10 eV[/tex], so we can find the work function of the metal by re-arranging eq. (1):
[tex]\phi = hf-K_{max} = 3.12 eV-1.10 eV=2.02 eV[/tex]

In the second part of the problem, we have light with wavelength [tex]\lambda=285 nm=285 \cdot 10^{-9}m[/tex], which corresponds to a frequency of
[tex]f= \frac{c}{\lambda}= \frac{3 \cdot 10^8 m/s}{285 \cdot 10^{-9}m}=1.05 \cdot 10^{15} Hz [/tex]
And so the photons have energy
[tex]E=hf=(6.6 \cdot 10^{-34} Js)(1.05 \cdot 10^{15}Hz)=6.93 \cdot 10^{-19} J[/tex]
which corresponds to
[tex]E=6.93 \cdot 10^{-19}J = 4.33 eV[/tex]

And if we use again eq.(1), we can now find the new maximum kinetic energy of the photoelectrons:
[tex]K_{max}=hf-\phi=4.33 eV-2.02 eV=2.31 eV[/tex]

Certain underwater vehicles are capable of exploring some of the deepest regions of the ocean. consider the density of seawater to be 1025 kg/m3. if such a vehicle were submerged to a depth of 8513 m below the surface, what force would be exerted on the vehicle's observation window (radius = 9.3 cm)?

Answers

The pressure exerted by the water at a depth of h=8513 m below the surface is given by Stevin's law:
[tex]p=p_a + \rho g h[/tex]
where
[tex]p_a =1.013\cdot 10^5 Pa[/tex] is the atmospheric pressure
[tex]\rho=1025 kg/m^3[/tex] is the water density
[tex]g=9.81 m/s^2[/tex] is the gravitational acceleration
[tex]h=8513 m[/tex] is the depth

If we plug the numbers into the formula, we find the pressure exerted on the window of the vehicle:
[tex]p=1.013 \cdot 10^5 Pa + (1025 kg/m^3)(9.81 m/s^2)(8513 m)=8.57 \cdot 10^7 Pa[/tex]

The area of the window is
[tex]A=\pi r^2 = \pi (0.093 m)^2 = 0.027 m^2[/tex]

And so the force exerted on the window is
[tex]F=pA=(8.57 \cdot 10^7 Pa)(0.027 m^2)=2.31 \cdot 10^6 N[/tex]

Answers

Silver is a very good conductor, this means its resistivity is very low (from table, we can check the precise value, which is [tex]\rho_s = 1.6 \cdot 10^{-8} \Omega m[/tex]).

Pure water, instead, is a very bad conductor, this means its resistivity is very high, of order of [tex]k \Omega \cdot m[/tex] ([tex]10^3 \Omega m[/tex] ). Even without knowing the precise value of the pure water resistivity, we can estimate the ratio between the pure water resistivity and the silver resistivity by comparing the two orders of magnitude:
[tex]r= \frac{10^3 \Omega m}{10^{-8} \Omega m} \sim 10^{11} [/tex]

Therefore, we can say that the correct answer is
[tex]3 \cdot 10^{11} : 1[/tex]

The resistivity is a dependent factor for the ease of allowing electrons to flow. The approximate ratio of the resistivity of pure water to silver is [tex]3 \times 10^{11} :1[/tex].

What is Resistivity?

The property of the material that determines the actual resistance offered by the material to the flow of current through a cross-section area, is known as the resistivity of the material.

Pure water is a bad conductor of electricity which means it offers high resistance to the flow of electric current. So, the standard value of the resistivity of pure water is around [tex]10^{3} \;\rm \Omega.m[/tex].

On the other hand, silver is one of the materials which allows higher conduction of electricity through it, hence it has a lower level of resistivity of the order [tex]1.60 \times 10^{-8} \;\rm \Omega.m[/tex]

So, the ratio of resistivity of water to the silver is,

[tex]=\dfrac{10^{3}}{ 1.6 \times 10^{-8}}\\\\\approx 3 \times10^{11} : 1[/tex]
