What event instigated germany’s push for energy from renewable resources?.
Renewable resources are those energy resources which will never end. Germany aims to be completely dependent on renewable energy resources by 2035.
What are renewable resources?Renewable resources are those energy resources which will never end. A few examples of such energy resources are Solar Energy, Wind Energy, etc.
Germany is a European country, therefore, it is a cold country and is highly dependent on the natural resources of Russia. As the war is going on between Russia and Ukraine, it is hard for countries like Germany to put sanctions on Russia because of its dependency on its resources.
Thus, Germany wants to be a self-dependent country in terms of electricity and wants to completely stop the use of non-renewable resources for the production of electricity.

Compute the theoretical density of diamond given that the C-C distance and bond angle are 0.154 nm and 109.5o, respectively. The atomic weight of carbon is 12.01 g/mol.
The theoretical density of diamond given that the C-C distance and bond angle are 0.154 nm and 109.5° respectively is; 3.54 g/cm³
What is the Theoretical Density?
The first thing we will do is to get the unit cell edge length from the given C - C distance.
From the structure of diamond;
Φ = ¹/₂ * bond angle
Φ = ¹/₂ * 109.5°
Φ = 54.75°
Thus;
θ = 90° - 54.75°
θ = 35.25°
Let the height from a point to the base of the cube of the structure be x. Thus;
x = a/4 = y sin θ
where a is unit cell edge length and y is C -C length. Thus;
a = 4y sin θ
a = 4 * (0.154 * 10⁻⁹) * sin 35.25°
a = 3.56 * 10⁻⁸ cm
The unit cell volume is;
V_c = a³
Thus; V_c = (3.56 * 10⁻⁸)³
V_c = 4.51 * 10⁻²³ cm³
Now, there are 8 equivalent atoms per unit cell and as such density is calculated from;
ρ = (n * A_c)/(V_c * N_a)
A_c is atomic weight of diamond = 12.01 g/mol
N_a is avogadro's number = 6.022 * 10²² atoms/g
Thus;
ρ = (8 * 12.01)/(4.51 * 10⁻²³ * 6.022 * 10²²)
ρ = 3.54 g/cm³

NEED HELPASAP what is the moisture content of a board if a test sample that originally weighed 11. 5 oz was found to weigh 10 oz after oven drying?
Answer:
11.5-10/10= 0.15x100 =15%
Explanation:
The moisture content of the board is 13.04% as per the given data.
What is moisture content?Simply said, a product's moisture content is its water content. It affects a substance's weight, density, viscosity, conductivity, and other physical characteristics.
The original weight of the test sample was 11.5 oz, and the weight of the sample after oven-drying was 10 oz.
The amount of moisture lost during the oven-drying process is equal to the original weight of the sample minus the weight of the sample after drying, or:
11.5 oz - 10 oz = 1.5 oz
To calculate the moisture content, you then divide the amount of moisture lost by the original weight of the sample and multiply by 100 to express the result as a percentage:
(1.5 oz / 11.5 oz) x 100% = 13.04%
Thus, the moisture content of the board is 13.04%.

A small PWR plant operates at a power of 485 MWt. The core, which is approximately 75.4 in. in diameter and 91.9 in. high, consists of a square lattice of 23,142 fuel tubes of thickness 0.021 in. and inner diameter of 0.298 in. on a 0.422-in. pitch. The tubes are filled with 3.40 w/o-enriched The core is cooled by water, which enters at the bottom at and passes through the core at a rate of at 2,015 psia. Compute (a) the average temperature of the water leaving the core; (b) the average power density in kW/liter; (c) the maximum heat production rate, assuming the reactor core is bare.
Based on the calculations, the average temperature of the water leaving this core is equal to 531.11 Btu/lb.
How to calculate the average temperature of the water.Since the core is cooled by water, which enters at the bottom at 496°F, the heat input ([tex]h_{in}[/tex]) would be equal to 483.02 Btu/lb based on the steam table.
Given the following data:
Power = 485 MWt to Btu/hr = 1.635 × 10⁹ Btu/hr.Diameter = 75.4 in.Height = 91.9 in.Thickness = 0.021 in. Inner diameter = 0.298 in.Pitch = 0.422-in. Work done = 34 × 10⁶ lb/hr.Substituting the given parameters into the formula, we have;
[tex]h_{out}= \frac{q}{w} + h_{in}\\\\h_{out}= \frac{1.635 \times 10^9}{34 \times 10^6} + 483.02\\\\h_{out}= 48.09 + 483.02\\\\h_{out}= 531.11\;Btu/lb[/tex]
How to calculate the average power density.First of all, we would determine the area of this core by using this formula:
Area = πd²/2
Area = 3.142 × (0.298/2)²
Area = 0.0698 in².
Mathematically, the average power density is given by:
[tex]q_{av}=\frac{q}{W} =\frac{q}{\pi A^2H \times 23142} \\\\q_{av}=\frac{485 \times 10^3}{3.142 \times 0.0698^2 \times 91.9 \times 0.01639 \times 23142} \\\\q_{av}=199.5\;kW/liter.[/tex]
How to calculate maximum heat production rate.In this scenario, we would assume the reactor core is bare. Thus, the heat is given by:
[tex]q(0) = \frac{2.32PE_1}{HE_R} \\\\q(0) =\frac{2.32 \times 485 \times 180}{23142 \times 200} \\\\q(0) =0.044 \;MW = 1.5 \times 10^8 \;Btu/hr^2[/tex]
For the maximum heat production rate, we have:
[tex]q_{max}=\frac{q(0)}{2HA^2} \\\\q_{max}=\frac{1.5 \times 10^8}{2 \times (\frac{75.4}{2} \times \frac{1}{12}) \times (\frac{0.298}{2} \times \frac{1}{12})} \\\\q_{max}=\frac{1.5 \times 10^8}{2 \times 3.1417 \times 0.00124} \\\\q_{max}=\frac{1.5 \times 10^5}{0.007791416}\\\\q_{max}=1.55 \times 10^8 \;Btu/hr.ft^3[/tex]

Calculate (413,465,789 mod 6), giving an answer between 0 and 5, and using a small number of steps. Show your steps.
Answer:
5
Explanation:
The sum of the digits of the number is ...
(4+1+3)+(4+6+5)+(7+8+9) = 8+15+24 = 47
The sum of those digits is 4+7=11, and those digits sum to 1+1 = 2.
That is, the value of the number mod 9 (or 3) is 2.
The ones digit is odd, so the value of the number mod 2 is 1.
This combination of modulo values tells you the mod 6 result is 5.
_____
Additional comment
We can look at the (mod2, mod3) values of the numbers 0 to 5:
0 ⇒ (0, 0)
1 ⇒ (1, 1)
2 ⇒ (0, 2)
3 ⇒ (1, 0)
4 ⇒ (0, 1)
5 ⇒ (1, 2) . . . . the mod {2, 3} results we have for the number of interest.
This process of adding up the digits repeatedly is referred to as "casting out 9s." The result of it is the modulo 9 value of the number (with 0 mapped to 9). Checking the mod 9 result of arithmetic operations is one quick way to spot certain kinds of errors. It can also be used as part of a divisibility test for 3 or 9.
Advantage and disadvantages of Bessemer process of steel making
Advantages:
- allowed steel to be produced without fuel
- using the impurities of the iron to create the necessary heat
- reduced the costs of steel production
Disadvantages:
- could convert only a pig iron low in phosphorus and sulfur
- these elements could have been removed by adding a basic flux such as lime, but the basic sl*g produced would have degraded the acidic refractory lining of Bessemer's converter.

PLEASE MARK ME BRAINLIEST IF MY ANSWER IS CORRECT PLEASEA plant has ten machines and currently operates two 8-hr shift per day, 5 days per week, 50 weeks per year. the ten machines produce the same part each at a rate of 30 pc/hr. (a) determine annual production capacity of this plant. (b) if the plant were to operate three 8-hr shifts per day, 6 days per week, 51 weeks per year, determine the annual percentage increase in plant capacity
Answer:
83.6%
Explanation:
(a)On its current schedule, the plant can theoretically produce ...
(30 pc/h/machine)(10 machine)(8 h/shift)(2 shift/day)(5 day/wk)(50 wk/yr)
= (30)(10)(8)(2)(5)(50) pc/yr = 1,200,000 pc/yr
__
(b)On the proposed schedule, this production becomes ...
(30 pc/mach)(10 mach)(8 h/sh)(3 sh/da)(6 da/wk)(51 wk/yr)
= (30)(10)(8)(3)(6)(51) pc/yr = 2,203,200 pc/yr
The increase in capacity is ...
(2,203,200/1,200,000 -1) × 100% = 83.6% . . . capacity increase
_____
Additional comment
The number of parts per shift did not change. Only the number of shifts per year changed. It went up by a factor of (3/2)(6/5)(51/50) = 1.836. Hence the 83.6% increase in capacity.
We have to assume that maintenance and repair are done as effectvely as before in the reduced down time that each machine has.
