If you measure the average brightness and pulsation period of a cepheid variable star, you can also determine its distance.

Cepheid variable stars belong to a class of stars that have a distinct relationship between variation period and luminosity.

Their period of cycle and luminosity are closely related to each other and they differ in temperature and diameter.

As their brightness increases and decreases, therefore, it helps out in the measurement of intergalactic and interstellar distances.

The changes in amplitude of their motion and cycle period have a definite impact on their brightness which enables us to determine their distance.

According to the solving molecules are there in the gas thus, option (b) 5.87 x 10²⁴ is the correct answer.

Given conditions:

Volume, V = 80 L

Pressure, P = 2 atm

Temperature, T = 300 K

The Ideal Gas Equation is

PV = n RT

Where, P is pressure in Pa V is volume in m³n is the number of moles R is the gas constant T is the temperature in K The pressure needs to be converted from atm to

Pa.1 atm = 1.013 x 105 Pa

So,2 atm = 2 × 1.013 x 105

Pa= 2.026 x 105 Pa

The gas constant, R = 8314 J/(mol K)

To convert this into J/(molecule K), we have to divide it by Avogadro's number, № which is 6.022 x 10²³ mol⁻¹.

R/nᵢ = R/№k Where,

k = Boltzmann constant = R/№k

= R/№

= 8314/6.022 x 10²³k

= 1.38 x 10⁻²³ J/K n/V

= P/RT

Here, n is the number of moles of gas in volume V.

So, the number of molecules in 80 L of gas having a gauge pressure of 2 atm and a temperature of 300 K is,

Number of molecules = 1042.87 mol/m³ × №

= 1042.87 × 6.022 × 10²³

= 6.27 × 10²⁶

Thus, option (b) 5.87 x 10²⁴ is the correct answer.

Answer:

The Answer is C. The force of gravity

Explanation:

This is because it is the force of gravity exerted or inflicted upon the object or organism. With more gravity inflicting upon an object the heavier it feels. In fact, weight and gravity have such a close relationship that the equation for weight is F = M x A where F represents the objects weight in Newtons, M equals it's mass, and A represents the downward acceleration due to the gravity.

Answer:

The answer is c

Explanation:

Answer:

true

Explanation:

The law of conservation of mass states that in a chemical reaction mass is neither created nor destroyed. For example, the carbon atom in coal becomes carbon dioxide when it is burned. The carbon atom changes from a solid structure to a gas but its mass does not change.

Answer:

76*

Explanation:

Answer:

Q= 31,798.4

Explanation:

You would use the specific heat formula which is Q=mCΔt

m(mass)=100

C(Specific heat capacity)= 4.184

Δt(change in temperature)=24-100=-76 or just 76 in this case

so Q=(100)(4.184)(76)=

418.4(76)=31,798.4

Therefore the missing value Q(heat lost or gained) equal 31,798.4

The cycle time of the entire line is 30.00528 minutes per part.

To calculate the cycle time of the entire line, we need to consider the processing times, failures, and repairs of both the milling machine and the turning machine.

For the milling machine:

Mean processing time (t0) = 15 mins

Standard deviation of processing time (sigma0) = 3 mins

Mean time to failure (MTTF) = 750 mins

Mean time to repair (MTTR) = 200 mins

For the turning machine:

Mean processing time (t0) = 15 mins

Standard deviation of processing time (sigma0) = 3 mins

Mean time to failure (MTTF) = 110 mins

Mean time to repair (MTTR) = 38 mins

We also know that the arrival rate to the milling machine is 1.2 parts/hr, with a coefficient of variation (CV) of 1.

To calculate the cycle time, we can use the following formula:

Cycle time = Processing time + Failure time + Repair time

Processing time:

The processing time is the sum of the mean processing times of the milling machine and the turning machine:

Processing time = t0 (milling machine) + t0 (turning machine) = 15 mins + 15 mins = 30 mins

Failure time:

The failure time is the inverse of the MTTF, considering the arrival rate:

Failure time = 1 / (MTTF * Arrival rate) = 1 / (750 mins * (1.2 parts/60 mins)) = 0.00111 parts/min

Repair time:

The repair time is the inverse of the MTTR, considering the coefficient of variation (CV):

Repair time = 1 / (MTTR * CV) = 1 / (200 mins * 1.2) = 0.00417 parts/min

Cycle time:

Cycle time = Processing time + Failure time + Repair time = 30 mins + 0.00111 parts/min + 0.00417 parts/min

The action spectrum is broader than the absorption spectrum because it takes into account all wavelengths of light that can drive a particular biological process, not just those absorbed by a specific pigment.

The action spectrum shows the efficiency of a biological process, such as photosynthesis or vision, at different wavelengths of light. It measures the biological response to each wavelength, regardless of which pigment is responsible for absorbing the light.

On the other hand, the absorption spectrum only shows the wavelengths absorbed by a particular pigment, such as chlorophyll or rhodopsin. Therefore, the action spectrum is broader than the absorption spectrum because it considers all the wavelengths that can activate the biological process, while the absorption spectrum only shows the wavelengths absorbed by a specific pigment.

when the astronaut arrives back on Earth, he will be approximately 40 years old.

To solve this problem, we can use the concept of time dilation in special relativity.

Given that the astronaut travels to a planet 10 light-years away and it takes 20 years on Earth for him to reach there, we can calculate his speed. Since the distance is 10 light-years and the time taken is 20 years, we can divide the distance by the time to find the speed.

Speed = Distance / Time
Speed = 10 ly / 20 years
Speed = 0.5 ly/year

Now, the astronaut turns around and comes back to Earth at the same speed. This means that for the return journey, he will also take 20 years on Earth.

Since the total time taken for the round trip is 20 + 20 = 40 years on Earth, we can calculate how much time has passed for the astronaut during this period using time dilation.

According to time dilation, the time experienced by the moving object (the astronaut) is dilated or stretched relative to the stationary observer (Earth). The time dilation factor can be calculated using the formula:

Time dilation factor = 1 / √(1 - (v^2 / c^2))

Where v is the speed of the astronaut and c is the speed of light (approximately 300,000 km/s).

Plugging in the values:

Time dilation factor = 1 / √(1 - (0.5^2 / (300,000^2)))
Time dilation factor ≈ 1 / √(1 - 0.00000000333)
Time dilation factor ≈ 1 / √0.99999999667
Time dilation factor ≈ 1 / 0.999999998335
Time dilation factor ≈ 1.000000001665

Now, we can calculate the time experienced by the astronaut during the round trip:

Time experienced by the astronaut = Time dilation factor * Time on Earth
Time experienced by the astronaut = 1.000000001665 * 40 years
Time experienced by the astronaut ≈ 40.0000000666 years

Therefore, when the astronaut arrives back on Earth, he will be approximately 40 years old.

The heating curve could be describing processes such as boiling and endothermic reactions.A heating curve is a graphical representation that shows the changes in temperature as a substance is heated.

It typically consists of two distinct segments: heating and phase change. Boiling is a process where a substance changes from its liquid phase to its gaseous phase. During the heating phase, the temperature of the substance gradually increases until it reaches its boiling point. At this point, the substance undergoes a phase change, and the temperature remains constant until all the liquid has vaporized. Therefore, the heating curve could be describing the process of boiling.

Endothermic reactions are chemical reactions that absorb heat from their surroundings, resulting in a decrease in temperature. If the heating curve represents the temperature changes during an endothermic reaction, we would observe a decrease or plateau in temperature during the reaction, followed by a subsequent increase. Thus, the heating curve could also be describing an endothermic reaction.

Condensation, on the other hand, is the process by which a substance changes from its gaseous phase to its liquid phase. It typically occurs when a gas is cooled down, and the temperature decreases. However, the heating curve represents temperature changes during the heating process, not cooling. Therefore, condensation is not applicable to the heating curve.
