Answer:

20°C

Explanation:

The relationship between temperature in degrees Fahrenheit(F) and degrees Centigrade (C) is

C = (F - 32) x 5/9

Given F = 68°F

C = (68-32) x 5/9

  =  36 x 5/9
  =  36/9 x 5

  = 4 x 5

  = 20°C

Answer:

20º C

Explanation:

The formula for converting Fahrenheit to Celsius is:

C = 5/9 • (F - 32)

Plugging 68º for F we get:

C = 5/9 •(68º-32)

C = 5/9 •(36)

C = 20º

Mapping methods such as digital mapping using satellite imagery or aerial photography can provide much higher resolution and accuracy. These methods utilize advanced technology and can capture detailed features and measurements with greater precision.

The mapping method with the lowest resolution is usually the one that has a smaller scale or less detailed data. For example, a world map would have a lower resolution than a city map since it covers a much larger area and shows less detail. Therefore, the mapping method with the lowest resolution depends on the scale and level of detail in the data being used.

Explanation:

The forward voltage at which the diode current is equal to 1.00 mA is approximately 0.62 V.

To calculate the forward voltage at which the diode current is equal to 1.00 mA, we need to use the following equation:

J = J0 * (exp(qV/kT) - 1)

where J is the diode current, J0 is the reverse saturation current, q is the charge of an electron, V is the forward voltage, k is the Boltzmann constant, and T is the temperature in Kelvin.

We can rewrite the above equation as:

V = (kT/q) * ln(J/J0 + 1)

Given that the diode area is A = 1.0x10⁴ cm², the diode current at Vse = 0 is:

J0 = AR * A * T² * exp(-qose/kT) = 7.6x10⁵ A/cm² * 1.0x10⁴ cm² * (300 K)² * exp(-q0.80 eV/kT) = 3.68x10⁻⁹ A

Substituting J = 1.00 mA = 1.00x10⁻³ A, we can solve for the forward voltage:

V = (kT/q) * ln(J/J0 + 1) = (1.38x10⁻²³ J/K * 300 K / 1.60x10⁻¹⁹ C) * ln(1.00x10^⁻³A / 3.68x10⁻⁹ A + 1) = 0.62 V

In order to determine the electric potential at the inner surface of a conducting shell, we need to know the charge distribution on the shell and the potential at a reference point.

Assuming the conducting shell is a spherical shell with uniform charge density, we can use the following steps to determine the electric potential at the inner surface:

Define a reference point as the point at infinity where the potential is zero. Since the conducting shell is an equipotential surface, the potential is constant at all points on the inner surface. Use the definition of electric potential to calculate the potential difference between the reference point and a point on the inner surface of the shell.

The potential at the inner surface of the shell is the sum of the potential difference and the potential at the reference point. Therefore, the electric potential at the inner surface of the conducting shell, V(B), is given by:

V(B) = V(infinity) + ΔV

where V(infinity) is the potential at infinity, which is defined to be zero, and ΔV is the potential difference between infinity and the inner surface of the shell.

Assuming the conducting shell has a total charge Q and a radius R, the potential difference can be calculated as:

ΔV = kQ/R

where k is the Coulomb constant. Therefore, the electric potential at the inner surface of the conducting shell is:

V(B) = 0 + kQ/R

which indicates that the potential at the inner surface of the shell is proportional to the total charge on the shell and inversely proportional to the radius of the shell.

Inside a freely-falling elevator, there would be no apparent weight for you.So option B is correct.

Inside a freely-falling elevator, there is still a gravitational force acting on you. However, since both you and the elevator are falling at the same rate, you would experience a sensation of weightlessness. Your apparent weight, which is the force exerted on a body due to gravity, would be zero. This is because there is no contact force between you and the elevator floor that would provide a normal force to counteract gravity. Therefore, the correct option is that there would be no apparent weight for you.

The mass of the gas that fills the flask is 0.316 grams. To find the mass of the gas, we need to consider the changes in mass and volume of the flask before and after vaporization.

Firstly, we calculate the change in mass of the flask after vaporization, which is 123.907 g - 123.591 g = 0.316 g. This change in mass represents the mass of the vaporized liquid.

Next, we need to determine the volume of the flask. Since the flask was completely filled with water at 18.5 °C, we can assume that the volume of the flask is equal to the volume of water it can hold. We can use the density of water, which is approximately 1 g/cm³, to convert the mass of the water-filled flask (375.639 g) to volume.

Volume = Mass / Density = 375.639 g / 1 g/cm³ = 375.639 cm³

Now we need to consider the ideal gas law to relate the volume and mass of the gas at room temperature and pressure. The ideal gas law equation is PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin.

Since we know the temperature and pressure, we can rearrange the ideal gas law equation to solve for the number of moles (n):

n = PV / RT

Converting the pressure from mm Hg to atm (atmospheres) and the temperature from Celsius to Kelvin:

P = 760.2 mm Hg / 760 mm Hg/atm = 1 atm

T = 18.5 °C + 273.15 = 291.65 K

Substituting the values into the equation, we get:

\(n = (1 atm) \times (375.639 cm^3) / [(0.0821 L\,atm/mol\,K) \times (291.65 K)]=0.0123 mol\)

Finally, we convert the moles of gas to grams using the molar mass of the gas. Since the identity of the gas is not provided, we cannot determine its molar mass precisely. However, assuming the gas is a volatile organic compound, we can estimate its molar mass to be around 26 g/mol. Therefore, the mass of the gas is:

\(Mass = moles \times molar mass = (0.0123 mol) \times (26 g/mol) = 0.316 g\)

Hence, the mass of the gas that fills the flask is approximately 0.316 grams.

The main difference between these types of motion is that circular motion is a special case of rotational motion, where the distance between the body’s centre of mass and the axis of rotation remains fixed.

Rotational motion is based around the idea of rotation of a body about its center of mass. In rotational motion, the axis of rotation and centre of mass could change whereas in circular motion, the axis of rotation and centre of mass does not change.

Circular motion is a movement of an object along the circumference of a circle or rotation along a circular path and can either have a constant angular rotation rate and constant speed, or it can exist with a changing rate of rotation.

The modulus of elasticity, E, is a measure of a material's stiffness and ability to resist deformation when a force is applied. It is defined as the ratio of stress to strain within the elastic range of the material. In other words, it describes how much a material will stretch or compress under a given force.

The modulus of elasticity is important because it allows engineers to predict how materials will behave under different conditions, such as temperature changes, loading conditions, and other factors. It also helps to determine the maximum load a material can withstand before it starts to deform or break.

In detail, the modulus of elasticity is a fundamental property of a material that describes its ability to resist deformation when subjected to external forces. It is calculated by measuring the stress and strain of the material and using the equation E = σ/ε, where σ is stress and ε is strain.

The modulus of elasticity is important in many areas of engineering, such as structural design, materials science, and mechanics. It helps to ensure that structures and materials are designed and tested to withstand the loads and stresses they will be subjected to, and it provides a basis for comparing different materials and choosing the best one for a particular application.

In summary, the modulus of elasticity, E, is a material property that describes its stiffness and resistance to deformation. It is correctly determined using Hooke's Law and is crucial for predicting the mechanical behavior of materials when subjected to stress.

Answer:

A) R = 190.42 Ω

B) P = 5.325 W

Explanation:

We are given;

Total power;P_tot = 7.1 W

Voltage;V = 26 V

A)We are told that while the battery is still connected, one of the resistors is heated, so that its resistance doubles.

Thus, the power is doubled.

Now, formula for power is;

P = IV

Thus, since power is doubled, we have;

P = 2(IV)

Now, formula for current is; I = V/R

So, P = 2V²/R

Making R the subject, we have;

R = 2V²/P

In this question, P is p_total = 7.1 W

Thus;

R = (2 × 26²)/7.1

R = 190.42 Ω

B) Now, the resistance of the resistors are R and 2R.

Formula for power in this context is;

P = V²/R

Thus,

Total power delivered to the resistors is;

P = V²/R + V²/2R

P = 3V²/2R

P = (3 × 26²)/(2 × 190.42)

P = 5.325 W
