Answer 2

Energy paid for in your heating bill is converted into thermal energy to heat your home, distributing through power lines or pipelines. Some of the energy is lost to the environment, while the rest maintains a warm home temperature. Continuous payment is necessary to compensate for ongoing heat loss.

When you pay for energy to heat your home, you are essentially purchasing thermal energy to maintain a comfortable temperature inside. Here's a step-by-step explanation of what happens to the energy:

Generation: The energy you pay for is generated by power plants, which may use fossil fuels, nuclear energy, or renewable sources. This energy is then converted into electrical or thermal energy.Distribution: This energy is distributed through power lines or pipelines to your home.Use in Heating: Inside your home, energy is converted by your heating system into thermal energy (heat). This heat is then transferred to the air and materials in your home to maintain a warm temperature.Heat Transfer: Some of this thermal energy is inevitably lost to the outside environment due to heat transfer. The remaining energy stays within your home, ensuring a comfortable living space.Energy Dissipation: Over time, the thermal energy dissipates, balancing out with the environmental temperature unless continuously supplied.

This process explains why you continuously pay for heating during colder months – it compensates for the continuous loss of heat to the outside environment.

For an isolated system, the law of conservation of momentum is valid: A. for inelastic collisions. B. for elastic collisions. C. only when there are no collisions. D. for all types of collisions.

Answers

The correct answer is:
D. for all types of collisions.

In fact, for an isolated system, the law of conservation of momentum is always valid. Instead, kinetic energy is conserved only when the collision is elastic, while for inelastic collisions kinetic energy is not conserved.

The law of conservation of momentum is valid in isolated systems for all types of collisions, both elastic and inelastic.

The law of conservation of momentum is valid for an isolated system, meaning that no net external force is acting on the system. This principle applies to both types of collisions: elastic collisions and inelastic collisions. In elastic collisions, not only is momentum conserved, but kinetic energy is also conserved. In inelastic collisions, however, while kinetic energy is not conserved, the conservation of momentum still holds true. Therefore, for an isolated system, the law of conservation of momentum is valid for all types of collisions, regardless of whether they are elastic or inelastic.

Three 1.2 ohm lamps are connected in series and connected to a 3 volt battery. Calculate the total current in the circuit

Answers

Since the 3 lamps are connected in series, their equivalent resistance is equal to the sum of the three resistors:
[tex]R_{eq} =R_1+R_2+R_3=1.2 \Omega + 1.2 \Omega +1.2 \Omega = 3.6 \Omega[/tex]

And the total current flowing in the circuit can be calculated by using Ohm's law:
[tex]I= \frac{V}{R_{eq}} [/tex]
where V is the voltage of the battery. By using V=3 V, we find
[tex]I= \frac{3 V}{3.6 \Omega}= 0.83 A[/tex]

A neutral copper ball is suspended by a string. a positively charged insulating rod is placed near the ball, which is observed to be attracted to the rod. why is this? 1. the ball becomes positively charged by induction. 2. the string is not a perfect conductor. 3. there is a rearrangement of the electrons in the ball. 4. the ball becomes negatively charged by induction. 5. the number of electrons i

Answers

The correct answer is:
3. there is a rearrangement of the electrons in the ball.

In fact, the ball is made by copper, which is a good conductor, therefore its electrons are free to move on the surface of the ball. When the positively charged rod is placed near to the ball, the electrons in the ball re-arrange, in particular they are attracted from the positive charges of the rod so they move closer to it. And since opposite-sign charges attract each other, the ball is then attracted by the rod.

The copper ball is attracted to the rod because the electrons in the ball rearrange themselves, making one side of the ball negative and the other positive. This process is known as electrostatic induction. Thus, option 3 is correct.

A neutral copper ball is observed to be attracted to a positively charged insulating rod due to electrostatic induction. Here's a step-by-step explanation:

Rearrangement of Electrons: When the positively charged rod is brought close to the neutral copper ball, the electrons in the copper ball are attracted towards the rod because opposite charges attract each other.Induced Polarization: This movement causes the side of the ball closer to the rod to become slightly negative due to the accumulation of electrons, while the side farther from the rod becomes slightly positive due to the lack of electrons.Attraction: The negatively charged side of the copper ball is attracted to the positively charged rod, causing the ball to move towards the rod.

Therefore, the correct reason for the observed attraction is the rearrangement of the electrons in the ball, making option 3 the correct answer.

Answers

(a) The lowest frequency (called fundamental frequency) of a wire stretched under a tension T is given by
[tex]f_1 = \frac{1}{2L} \sqrt{ \frac{T}{m/L} } [/tex]
where
L is the wire length
T is the tension
m is the wire mass

In our problem, L=10.9 m, m=55.8 g=0.0558 kg and T=253 N, therefore the fundamental frequency of the wire is
[tex]T= \frac{1}{2L} \sqrt{ \frac{T}{m/L} }= \frac{1}{2 \cdot 10.9 m} \sqrt{ \frac{253 N}{0.0558 kg/10.9 m} }= 10.2 Hz[/tex]

b) The frequency of the nth-harmonic for a standing wave in a wire is given by
[tex]f_n = n f_1[/tex]
where n is the order of the harmonic and f1 is the fundamental frequency. If we use n=2, we find the second lowest frequency of the wire:
[tex]f_2 = 2 f_1 = 2 \cdot 10.2 Hz=20.4 Hz[/tex]

c) Similarly, the third lowest frequency (third harmonic) is given by
[tex]f_3 = 3 f_1 = 3 \cdot 10.2 Hz = 30.6 Hz[/tex]

Calculate the quantity of energy produced per gram of reactant for the fusion of h-3 (atomic mass = 3.016049 amu) with h-1 (atomic mass = 1.007825 amu) to form he-4 (atomic mass = 4.002603 amu).

Answers

The total mass of one atom of H-3 and H-1 is 4.02387 amu. The stated amu is 4.002603.
There is a mass difference because it is being converted into energy.
Mass difference is 0.021271 amu
If it is converted to equivalent to grams per mole.
Equal to 0.000021271 kg
By using the Einsteins equation, E= mc∧2.
Per mole is
E=0.000021271 × 299792458∧2J
E = 1.91174 × 10∧12 J per mole
The reactant of one mole is 4.02387 grams
The energy which is being released per gram of reactant is 4.751 × 10∧11J/g

Final answer:

The energy produced per gram of reactant for the fusion of H-1 with H-3 to form He-4, can be calculated using the difference of total initial and final masses, which is then used in Einstein's mass-energy equivalence principle (E=mc²). The number of such reactions in 1 gram of reactant is used to convert the energy per reaction to energy per gram of reactant.

Explanation:

To calculate the energy produced per gram of reactant in fusion reaction, first let's understand what's happening in the fusion reaction of H-3 with H-1. A helium nucleus is formed with a mass that is 0.7% less than that of four hydrogen nuclei. This mass loss is converted into energy.

The masses of the reactants are 3.016049 u for H-3 and 1.007825 u for H-1, giving us a total initial mass of 4.023874 u. The mass of the helium atom produced, He-4, is 4.002603 u. The mass loss during the reaction equals initial mass minus final mass, which is 0.021271 u.]

Applying Einstein's mass-energy equivalence principle E=mc², where E is energy, m is the lost mass and c is the speed of light, the energy produced in the reaction, can be calculated. To convert amu to kilograms, multiply by 1.66054 x 10⁻²⁷. So, the mass lost is 3.53 x 10⁻²⁹ kg.

As speed of light c = 3 x 10^8 m/s, using the equation we get E = 3.53 x 10⁻²⁹ kg x (3 x 10⁸m/s)² = 3.18 x 10⁻¹²Joules.

Finally, to get the energy per gram, we calculate the number of such reactions in 1 gram of reactants. That would be (1 g)/(4.023874 g/mol) x Avogadro's number (6.02 x 10^23). Multiply this number with the energy produced per reaction to get the energy produced by 1 gram of reactant.

What is the freezing point of radiator fluid that is 50% antifreeze by mass? k f for water is 1.86 ∘ c/m?

Answers

Ethylene glycol is termed as the primary ingredients in antifreeze.
The ethylene glycol molecular formula is C₂H₆O₂.
Molar mass of C₂H₆O₂ is = (2×12) +(6×1) + (216) = 62g/mol
Now that antifreeze by mass is 50%, then there is 1kg of ethylene glycol which is present in 1kg of water.
ΔTf = Kf×m
ΔTf = depression in the freezing point.
= freezing point of water freezing point of the solution
= O°c - Tf
= -Tf
Kf = depression in freezing constant of water = 1.86°C/m
M is the molarity of the solution.
=(mass/molar mass) mass of solvent in kg
=1000g/62 (g/mol) /1kg
=16.13m
If we plug the value we get
-Tf = 1.86 × 16.13 = 30
Tf = -30°c

Answer:

-30.02 ºC

Explanation:

Assuming the antifreeze to be ethylene glycol (C₂H₆O₂) which is popular antifreeze.

Molar mass of ethylene glycol (C₂H₆O₂) = 62g/mol

Step 1: calculate the freezing point depression of the solution

ΔT = -Kf*M

where,

ΔT= depression in the freezing point.

M = the molarity of the solution (mol solute / Kg solvent)

Kf = molar freezing point constant of water = 1.86°C/m

To determine depression in the freezing point (ΔT), first we need to calculate;

molarity of solute (ethylene glycol) in mol mass of solvent (water) in kgmolarity of the solution (water +ethylene glycol)

Step 2: calculate the molarity of the solute (ethylene glycol)

Molar mass ethylene glycol = 62 g/mol

molarity of ethylene glycol in mol = 50 g / 62g/mol = 0.807 mol

Step 3: calculate mass of solvent in kg

There is 1kg of ethylene glycol which is present in 1kg of water

mass of solvent (water) in kg= 50 g/ 1000 g/ Kg = 0.050 Kg

Step 4: calculate the molarity of the solution (M)

M = 0.807 mol / 0.050 Kg = 16.14 m

Step 5: calculate the freezing point depression of the solution (ΔT)

ΔT = - Kf*M = -1.86 ºC/m x 16.14 m

= -30.02 ºC

What is the pressure of the gas in this mercury manometer if h = 63 mm and atmospheric pressure is 773 mmhg?

Answers

We can find the gas pressure by using a simple proportion.

In fact, if the pressure of the gas was equal to the atmospheric pressure:
[tex]p_a = 1.01 \cdot 10^5 Pa[/tex]
we know that the height in the mercury manometer would have been
[tex]h_a = 773 mm[/tex]

Therefore, if the heigth in the mercury manometer is
[tex]h=63 mm[/tex]
Then the pressure of the gas is given by the following proportion
[tex]h_a : p_a = h: p[/tex]
From which we find
[tex]p= \frac{h p_a}{h_a}= \frac{(63 mm)(1.01 \cdot 10^5 Pa)}{773 mm}=8231 Pa [/tex]

Two long parallel wires carry currents of 20 a and 5.0 a in opposite directions. the wires are separated by 0.20 m. what is the magnitude of the magnetic field midway between the two wires?

Answers

Final answer:

The magnitude of the magnetic field midway between two long parallel wires carrying currents of 20 A and 5.0 A in opposite directions and separated by 0.20 m is 4.5 x 10⁻⁵ T.

Explanation:

To find the magnitude of the magnetic field midway between the two long parallel wires carrying currents of 20 A and 5.0 A in opposite directions and separated by 0.20 m, we can use the formula for the magnetic field due to a long straight wire. The magnitude of the magnetic field at a distance r from the wire is given by: B = (μ₀ * I) / (2π * r). Since we are looking for the magnetic field midway between the wires, the distance from each wire to the point is half of the total separation, which is 0.10 m. Plugging in the values, we get: B = (4π * 10⁻⁷ T·m/A * (20 A + 5.0 A)) / (2π * 0.10 m) = 4.5 x 10⁻⁵ T.

Explanation:

To find the magnitude of the magnetic field midway between the two wires, we can use the formula for the magnetic field produced by a long straight wire:

B = (μ0 * I) / (2πr)

where B is the magnetic field, μ0 is the permeability of free space, I is the current, and r is the distance from the wire. In this case, we have two wires with currents of 20 A and 5 A, and they are separated by 0.20 m. Since we are interested in the magnetic field midway between the wires, the distance r will be half of the separation between the wires, which is 0.20 m / 2 = 0.10 m.

Plugging in the values, we get:

B = (4π * 10-7 T·m/A * (20 A - 5 A)) / (2π * 0.10 m) = (4 * 10-7 T·m/A * 15 A) / (0.20 m) = 3 * 10-6 T

So, the magnitude of the magnetic field midway between the two wires is 3 * 10-6 T.

a) 3.2 mW b) 0.11 mW c) 11 mW d) 1.1 mW e) .31 mW

Answers

The threshold of hearing is
[tex]I=1.0 \cdot 10^{-12}W/m^2[/tex]
and in order to hear the howler at a distance of 5 km, its sound should have at least this intensity.

The sound wave is emitted uniformly in all directions, so the area we should consider to calculate the power is the area of a sphere with radius
r=5 km=5000 m:
[tex]A=4 \pi r^2 = 4 \pi (5000 m)^2 =3.14 \cdot 10^8 m^2[/tex]

And by using these data, we can calculate the power emitted by the howler:
[tex]P=IA=(1.0 \cdot 10^{-12} W/m^2)(3.14 \cdot 10^8 m^2)=3.1 \cdot 10^{-4} W=0.31 mW[/tex]

Answers

1) a. mechanical waves require a medium to travel through
In fact, mechanical waves cannot travel trough empty space, but they always require a medium for their propagation. (on the contrary, electromagnetic waves can also travel through empty space)

2) d. gamma rays
In fact, gamma rays are the radiations with shortest wavelength on the electromagnetic spectrum (range in the picometer). Correspondingly, this is the radiation with highest energy, because the energy of the radiation is inversely proportional to its wavelength, according to:
[tex]E=h \frac{c}{\lambda} [/tex]

3) d. Infrared have lower frequency than x-rays
In fact, infrared radiation has frequency in the range of the THz (terahertz, [tex]10^{12} Hz[/tex]), while x-rays have frequency in the range of hundreds of PHz (Petahertz, [tex]10^{15}Hz[/tex]).

4) d. parallel
In longitudinal waves, the oscillations of the wave (such as the motion of the particles in a compression wave) occur in the direction parallel to the direction of propagation of the wave itself.

5) c. gases
Sound travels slowest in gases. In fact, the speed of sound is proportional to the density of the medium: the more dense the medium is, the faster is the sound in that medium, and vice-versa. Since gases are less dense than liquids and solids, sound travels slowest in gases. The reason is that sounds propagates through the oscillations of the molecules of the medium; if the medium is less dense (such as in gases), it takes more time to transmit the sound through the medium itself.

Final answer:

Mechanical waves require a medium to travel, gamma rays have the highest energy and shortest wavelength on the electromagnetic spectrum, x-rays have higher frequency than infrared, particles in a longitudinal wave move in parallel, and sound travels slowest in gases.

Explanation:

1. The correct statement about mechanical waves is 'a. mechanical waves require a medium to travel through'. Unlike electromagnetic waves, mechanical waves, such as sound or seismic waves, need a medium like air, water, or solids to propagate or move.

2. The waves with the shortest wavelength and highest energy on the electromagnetic spectrum are 'c. gamma rays'.

3. The true statement about infrared and X-Rays is 'd. Infrared has lower frequency than x-rays'. X-rays have a higher frequency and shorter wavelength compared to infrared waves, which directly impacts their energy levels, with X-rays having higher energy.

4. In a longitudinal wave (compression wave), the particles of matter move 'd. parallel' to the direction of the wave's propagation. This is different from transverse waves where particles move perpendicular to the wave direction.

5. Sound travels slowest in 'c. gases'. Sound waves travel the fastest through solids, slower through liquids, and slowest through gases.

True or false: the coefficient of thermal expansion governs the way a substance expands or contracts when it is heated or cooled

Answers

it is true because Thermal expansion is the tendency of matter to change in shape, area, and volume in response to a change in temperature, through heat transfer. Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, the kinetic energy of its molecules increases. Thus, the molecules begin moving more and usually maintain a greater average separation.
