a cell containing cyanamide is least likely to carry on the process of what transport

Answer:

As the projectile starts it’s motion from a vertical height at y=10m, it’s vertical motion may be described as under-

y= 10+ut-0.5gt^2

Where “u” is initial vertical velocity

= 45 sin60,

“g” is acceleration due to the gravity (10m/sec^2)

and “t” is time.

When the projectile touches the ground the vertical height “y”=0

Therefore the time “t” taken for the flight of the projectile till it touches the ground may be calculated from the above equation when y=0 as under -

0= 10+45sin60 x t- 0.5x10 t^2

0= 10+45x (√3/2)x t-5 t^2

t^2-9x (√3/2)x t-2 =0

t= [4.5√3 + √(243/4+4)]/2

t=[7.794+ 8.047]/2

t= 7.92 sec.

The horizontal distance travelled during this time=

vt

Where “v” is horizontal velocity = 45 cos60.

Therefore,

vt =45cos60 x 7.92

= 45x0.5x7.92

= 178.2 m

When 9.0g of aluminum at 200°C and 20g of copper are dropped into 44 cm³ of ethyl alcohol at 15°C, the final temperature of the mixture quickly reaches 23°C. We need to apply the principle of conservation of energy.

To analyze this scenario, we need to consider the heat gained or lost by each substance and apply the principle of conservation of energy.

The temperature change of a substance can be calculated using the formula:

q = m * c * ΔT,

where q is the heat gained or lost, m is the mass of the substance, c is its specific heat capacity, and ΔT is the change in temperature.

For aluminum, the heat gained is:

q_aluminum = m_aluminum * c_aluminum * ΔT_aluminum,

where m_aluminum = 9.0 g, c_aluminum is the specific heat capacity of aluminum, and ΔT_aluminum is the change in temperature for aluminum (23∘C - 200∘C).

Similarly, for copper, the heat gained is:

q_copper = m_copper * c_copper * ΔT_copper,

where m_copper = 20 g, c_copper is the specific heat capacity of copper, and ΔT_copper is the change in temperature for copper (23∘C - 15∘C).

For ethyl alcohol, the heat lost is:

q_ethyl_alcohol = m_ethyl_alcohol * c_ethyl_alcohol * ΔT_ethyl_alcohol,

where m_ethyl_alcohol = 44 cm3 (converted to grams using the density of ethyl alcohol), c_ethyl_alcohol is the specific heat capacity of ethyl alcohol, and ΔT_ethyl alcohol is the change in temperature for ethyl alcohol (23∘C - 15∘C).

By applying the conservation of energy principle, we can set up the equation:

q_aluminum + q_copper = -q_ethyl_alcohol,

since the heat gained by the metals must be equal to the heat lost by the ethyl alcohol. By plugging in the appropriate values, we can solve for the specific heat capacities or calculate the final temperature of the system. However, without the specific heat capacities provided, we cannot provide a numerical answer.

Galaxies are indeed large groups of stars, and they can range in size from dwarf galaxies with only a few million stars to massive galaxies with trillions of stars. However, the stars within a galaxy are not stationary. They are in constant motion, but what keeps them from moving away from each other is gravity.

Gravity is a fundamental force of nature that attracts objects with mass toward each other. In a galaxy, the stars are held together by the gravitational pull of other stars. The combined mass of all the stars in a galaxy creates a powerful gravitational force that keeps them together. The more massive a galaxy is, the stronger its gravitational force, which in turn keeps the stars tightly bound.

In addition to gravity, there is also dark matter. Dark matter is a mysterious substance that makes up a significant portion of the universe's total mass. It is believed that dark matter exists within galaxies and that its gravitational pull helps hold the stars together.

In summary, the stars within a galaxy are kept from moving away from each other by the powerful force of gravity. This force is created by the combined mass of all the stars and is further strengthened by the presence of dark matter.

The total inductance of the three coils connected in series is 4.35 henries.

To find the total inductance of coils connected in series, you simply add up the individual inductance values. However, it's important to ensure that all the inductance values are in the same unit before performing the addition.

Given that the inductance values are 250 millihenries, 3.5 henries, and 600 millihenries, we need to convert all the values to the same unit before adding them.

Converting the values to henries:

250 millihenries = 0.25 henries

600 millihenries = 0.6 henries

Now we can add the inductance values:

Total inductance = 0.25 henries + 3.5 henries + 0.6 henries

Total inductance = 4.35 henries

Therefore, the total inductance of the three coils connected in series is 4.35 henries.

Answer:true

Explanation:

Answer:

1. 59 Ω

2. 3 Ω

3. 0.625 kΩ

Explanation:

1. The total resistance in a series circuit is equal to the sum of the resistance.

\(R_T=R_1+R_2+R_3...\\R_T=20+19+20\\R_T=59\)

Therefore, the total resistance in the first circuit is 59 Ω.

2. The total resistance in a parallel circuit is equal to the sum of the reciprocals of the resistance.

\(\frac{1}{R_T} = \frac{1}{R_1} +\frac{1}{R_2} +\frac{1}{R_3} ...\\\frac{1}{R_T} = \frac{1}{6.0} +\frac{1}{12} +\frac{1}{36}+\frac{1}{18} \\\frac{1}{R_T} = \frac{1}{3} \\R_T=3\)

Therefore, the total resistance in the second circuit is 3 Ω.

3. This is another parallel circuit, so we use the same equation from above:

\(\frac{1}{R_T} = \frac{1}{R_1} +\frac{1}{R_2} +\frac{1}{R_3} ...\\\frac{1}{R_T} = \frac{1}{10} +\frac{1}{2} +\frac{1}{1} ...\\\frac{1}{R_T} =1.6\\R_T=\frac{1}{1.6}\)

Therefore, the total resistance in the third circuit is \(\frac{1}{1.6}\) kΩ, or 0.625 kΩ.

A steam engine ( Carnot engine ) has an efficiency of 73%. If the waste heat has a temperature of 24◦C, the temperature of the boiler is 827.41°C.

Both 121°C (250°F) and 132°C (270°F) are commonly used steam sterilising temperatures. For a short period of time, these temperatures (and other high temperatures) must be held in order to destroy microbes.

efficiency = 1 - (Temp_cold / Temp_hot)

Temp_cold = 24°C + 273.15 = 297.15 K

efficiency of 73%.=  .73

Tem_hot = T_cold / (1 - efficiency)= 297.15 K / (1 - 0.73)

Tem_hot = 1100.56 K

Finally, by deducting 273.15, we may change the temperature of the hot reservoir back to Celsius:

Tem_hot = 1100.56 K - 273.15 = 827.41°C

The density of the cooking oil is approximately 0.800 g/mL, calculated using a specific gravity of 0.784 and the density of water (1.02 g/mL).

The specific gravity of a substance is the ratio of its density to the density of a reference substance, usually water. In this case, the specific gravity of the cooking oil is given as 0.784.

Specific gravity = Density of cooking oil / Density of water

We are given the density of water as 1.02 g/mL. Rearranging the equation, we can solve for the density of the cooking oil:

Density of cooking oil = Specific gravity × Density of water

Density of cooking oil = 0.784 × 1.02 g/mL

To determine the ownership percentage you would demand in return for a $200,000 investment in the startup, several assumptions need to be made.

Here's an approach to calculate the value of the firm and the ownership percentage:

1. Estimate the future cash flows: We need to estimate the cash flows the company is expected to generate over the next four years. Given the provided information, we can assume the following:   - Year 1 cash flow: $250,000

  - Year 2 cash flow: $1,000,000   - Year 3 cash flow: $2,000,000 (double the previous year)

  - Year 4 cash flow: $3,000,000 (50% growth from Year 3)

2. Determine the discount rate: The discount rate is used to calculate the present value of future cash flows, taking into account the time value of money and the risk associated with the investment. Let's assume a discount rate of 20% to account for the startup's risk and the potential return on investment.

3. Calculate the present value of cash flows: Apply the discount rate to each year's cash flow to calculate their present values. Using a financial calculator or spreadsheet, the present values can be determined as follows:   - Year 1 present value: $250,000 / (1 + 0.20)¹

  - Year 2 present value: $1,000,000 / (1 + 0.20)²   - Year 3 present value: $2,000,000 / (1 + 0.20)³

  - Year 4 present value: $3,000,000 / (1 + 0.20)⁴

4. Determine the exit value: To estimate the potential exit value of the company at the end of year 4, a common approach is to use a multiple of the Year 4 cash flow. Let's assume a conservative multiple of 5 times the Year 4 cash flow. Thus, the exit value can be estimated as follows: Exit value = 5 * Year 4 cash flow

5. Calculate the firm value: The firm value is the sum of the present values of cash flows and the exit value. Calculate it as follows:   Firm value = Present value of Year 1 cash flow + Present value of Year 2 cash flow + Present value of Year 3 cash flow + Present value of Year 4 cash flow + Exit value

6. Determine the ownership percentage: To determine the ownership percentage for a $200,000 investment, divide the investment amount by the firm value and multiply by 100:

  Ownership percentage = ($200,000 / Firm value) * 100

Keep in mind that these calculations are based on assumptions and the accuracy of the estimated future cash flows and exit value will impact the results. It's important to thoroughly evaluate the market potential, competitive landscape, and other relevant factors before making any investment decisions.
