Explanation:

The new volume of the gas will increase to twice the original volume (Option D)

From the question given above, the following data were obtained:

The new volume of the gas can be obtained as illustrated below:

P₁V₁ / T₁ = P₂V₂ / T₂

Since the temperature is constant, we have:

P₁V₁ = P₂V₂

P × V = 0.5P × V₂

Divide both side by 0.5P

V₂ = (P × V) / 0.5P

V₂ = V / 0.5

Answer: B) 80.0 ohms

Explanation:

You just add the resistance 60 plus 20 equals 80

Here, the two resistors are if connected in series, then the equivalent resistance of the circuit is the sum of the individual resistances that is 80 ohms Hence, option B is correct.

Resistance is the hindrance to the current through a circuit. The resistance and current are in inverse proportionality. According to Ohm's law, the voltage across the circuit is the product of the resistance and current through the circuit.

In a parallel circuit, all components are connected in the parallel fashion and the current through each component is different. But in a series circuit, current through all the components is the same.

Equivalent resistance in a series circuit = R1 + R2 + R3 ...

For parallel circuit, 1/Req = 1/R1 + 1/R2 + ...

Here the two resistors are connected in series.

Hence, Req = 20 Ω + 60Ω = 180 Ω.

Therefore, the equivalent resistance of the circuit is 180 Ω.

The measure of the output produced per unit of an input is called "marginal product."

In economics, the concept of marginal product refers to the additional output that is generated by increasing the quantity of a particular input while keeping all other inputs constant.

It is calculated by dividing the change in total output by the change in the quantity of the input. Marginal product helps us understand the rate of change in production as inputs are increased or decreased.

For example, let's consider a factory that produces widgets. If the factory hires an additional worker and experiences an increase in output, the marginal product of that worker would be the additional number of widgets produced due to their contribution.

The concept of marginal product is essential for firms to determine the optimal level of input usage, as it helps them evaluate the productivity of each additional unit of input and make informed decisions regarding resource allocation.

In summary, the measure of output produced per unit of input is referred to as the marginal product, which helps assess the incremental productivity gained from additional units of input in a production process.

When receiving vacuum-packed meat, it is important to check the temperature to ensure that it has been stored and transported properly and is safe for consumption. Methods by which we can check the temperature are visual inspection, temperature probe, target temperature etc.

Here's how you can check the temperature of vacuum-packed meat during receiving:

1. Visual Inspection: Start by visually inspecting the packaging for any signs of damage, such as leaks, tears, or bulging. If the packaging appears compromised, it may indicate improper storage or potential bacterial growth, and the meat should not be accepted.

2. Temperature Probe: Use a food thermometer or a temperature probe designed for measuring the temperature of meat. Insert the probe into the thickest part of the meat, away from bones or any fat pockets, as these can affect the accuracy of the reading.

3. Target Temperature: The target temperature for vacuum-packed meat should be below 40°F (4°C). This temperature range helps to inhibit the growth of bacteria and ensures the meat remains fresh. If the temperature of the meat is above 40°F (4°C), it may indicate improper storage or potential spoilage.

4. Calibration: Make sure your food thermometer or temperature probe is calibrated and accurate to obtain reliable temperature readings. Follow the manufacturer's instructions for calibration if necessary.

5. Multiple Readings: Take temperature readings from various parts of the meat to ensure uniform cooling and to identify any temperature differences. If there are significant variations in temperature within the meat, it may suggest inadequate cooling or potential issues with the packaging.

6. Document and Record: Keep a record of the temperature readings and any observations. This documentation is essential for food safety records and can help trace any issues or discrepancies later on.

7. Follow Guidelines: Consult local food safety regulations and guidelines to ensure you are following specific requirements for temperature checks during receiving. Different regions or countries may have varying guidelines, so it is important to be familiar with the applicable regulations.

Remember, if the vacuum-packed meat shows signs of spoilage, has an off odor, or is stored at an unsafe temperature, it should not be accepted or consumed. It's crucial to prioritize food safety and adhere to proper temperature checks to prevent foodborne illnesses.

1. The phone is moving with a velocity of 20.77 m/s before racking into pieces

2. The time taken for the ball to come back to their hand is 0.82 s

3. The maximum height reached by the batarang is 49.03 m

4. The cliff is 1016.06 m high

5. The object is moving with a velocity of –8.6 m/s after 2 s

v² = u² + 2gh

v² = 0² + (2 × 9.8 × 22)

v² = 431.2

Take the square root of both side

v = √431.2

v = 20.77 m/s

We'll begin obtaining the time taken to reach the maximum height. This is illustrated below:

v = u – gt (since the ball is going against gravity)

0 = 4 – (9.8 × t)

0 = 4 – 9.8t

Collect like terms

0 – 4 = –9.8t

–4 = –9.8t

Divide both side by –9.8

t = –4 / –9.8

t = 0.41 s

Finally, we shall determine the time for the entire trip

T = 2t

T = 2 × 0.41

T = 0.82 s

v² = u² – 2gh (since the ball is going against gravity)

0² = 31² – (2 × 9.8 × h)

0 = 961 – 19.6h

Collect like terms

0 – 961 = –19.6h

–961 = –19.6h

Divide both side by –19.6

h = –961 / –19.6

h = 49.03 m

h = ½gt²

h = ½ × 9.8 × 14.4²

h = 4.9 × 207.36

h = 1016.06 m

v = u – gt (since the ball is going against gravity)

v = 11 – (9.8 × 2)

When Momentum is conserved it is called conservation of momentum.

Law of momentum conservation is a physical law that the momentum (total momentum) of a system is invariant unless an external force acts on the system (closed system).

The angle at which the first-order maximum occurs for 475-nm wavelength blue light falling on double slits separated by 0.0510 mm is approximately 0.53 degrees.

The angle at which the first-order maximum occurs for double-slit interference can be found using the formula:

sinθ = mλ/d

where θ is the angle between the central maximum and the first-order maximum, m is the order of the maximum (m = 1 for the first-order maximum), λ is the wavelength of the light, and d is the distance between the two slits.

In this case, we have:

λ = 475 nm = \(4.75 \times 10^{-7}\) m

d = 0.0510 mm = \(5.10 \times 10^{-5}\) m

m = 1

Substituting these values into the formula above, we get:

sinθ = mλ/d

= \(\dfrac{(1)(4.75 \times 10^{-7} m)}{(5.10 \times 10^{-5} m)}\)

≈ 0.0093

To find the angle θ, we can take the inverse sine of both sides:

θ = \(sin^{-1}(0.0093)\) ≈ 0.53 degrees

The resistance of the copper wire is 0.161 Ω. The resistance of a material depends on various factors, including its length, cross-sectional area, and temperature.

What is Resistance?

Resistance is a measure of how much a material opposes the flow of electric current. It is defined as the ratio of the voltage applied to a conductor to the current flowing through it, and is measured in ohms (Ω). Materials with high resistance are poor conductors of electricity, while materials with low resistance are good conductors.

We can use the formula for resistance of a wire:

R = (ρ * L) / A

where R is resistance, ρ is resistivity, L is length of the wire, and A is its cross-sectional area.

We know that the wires are identical, so they have the same length and cross-sectional area. Therefore, their resistances are proportional to their resistivities:

R_aluminum / R_copper = ρ_aluminum / ρ_copper

We can rearrange this to solve for the resistance of the copper wire:

R_copper = R_aluminum * ρ_copper / ρ_aluminum

Plugging in the given values, we get:

R_copper = 0.263 Ω * (1.72 x 10^-8 Ω·m) / (2.82 x 10^-8 Ω·m) = 0.161 Ω

Therefore, the resistance of the copper wire is 0.161 Ω.

Explanation:

The thermal energy lost per hour is 1.8288 x 10⁸ J and the engine absorbs 478,080 kJ (4.78 x 10⁸ J) of thermal energy every hour.

Use the Carnot efficiency formula to calculate the thermal energy absorbed by the engine per hour:

Efficiency = 1 - (T_cold / T_hot)

where T_cold and T_hot = temperatures of the cold and hot reservoirs in Kelvin.

Calculate the thermal energy absorbed per hour by the engine using the formula:

Thermal energy absorbed per hour = Power output / Efficiency

Convert the temperatures to Kelvin:

T_cold = 30°C + 273.15 = 303.15 K

T_hot = 524°C + 273.15 = 797.15 K

Calculate the efficiency:

Efficiency = 1 - (T_cold / T_hot)

Efficiency = 1 - (303.15 / 797.15)

Efficiency = 0.618

Calculate the thermal energy absorbed per hour:

Thermal energy absorbed per hour = Power output / Efficiency

Thermal energy absorbed per hour = 82 kW / 0.618

Thermal energy absorbed per hour = 132.8 kW

Finally, convert the result to joules:

Thermal energy absorbed per hour = 132.8 kW x 3600 s

Thermal energy absorbed per hour = 478,080 kJ

Therefore, the thermal energy absorbed by the engine per hour is 478,080 kJ or 4.78 x 10⁸ J.

The thermal energy lost per hour by the engine is equal to the thermal energy absorbed per hour minus the power output:

Thermal energy lost per hour = Thermal energy absorbed per hour - Power output

Thermal energy lost per hour = 478,080 kJ - 82 kW x 3600 s

Thermal energy lost per hour = 478,080 kJ - 295,200 kJ

Thermal energy lost per hour = 182,880 kJ

Finally, convert the result to joules:

Thermal energy lost per hour = 182,880 kJ = 1.8288 x 10⁸ J

Therefore, the thermal energy lost by the engine per hour is 1.8288 x 10⁸ J.
