How do you grow rice
Answer:
put some rice in a pot
Then mix it up with some sauce
pour in some dirt
and you'll get some sweet plant
Explanation:
Ideally, you need at least 40 continuous days of warm temps over 70 F. (21 C.) to grow rice.
First, you need to find one or several plastic containers without holes. One or several depends upon how many miniature pseudo rice paddies you want to create. Next, either purchase rice seed from a gardening supplier or buy long grain brown rice from a bulk foods store or in a bag. Organically grown rice is best and it can’t be white rice, which has been processed.
Fill the bucket or plastic container with 6 inches (15 cm.) of dirt or potting soil. Add water up to 2 inches (5 cm.) over the soil level. Add a handful of the long grain rice to the bucket. The rice will sink to the dirt. Keep the bucket in a warm, sunny area and move it to a warm place at night.
Rice plants don’t need too much care from here on out. Keep the water level at 2 inches (5 cm.) or so above the dirt. When the rice plants are 5-6 inches (12.5-15 cm.) tall, increase the water depth to 4 inches (10 cm.). Then, allow the water level to lower on its own over a period of time. Ideally, by the time you harvest them, the plants should no longer be in standing water.
If all goes well, rice is ready to harvest in its fourth month. The stalks will go from green to gold to indicate it is time to harvest. Harvesting rice means cutting and gathering the panicles attached to the stalks. To harvest the rice, cut the stalks and allow them to dry, wrapped in a newspaper, for two to three weeks in a warm, dry place.
Once the rice stalks have dried, roast in a very low heat oven (under 200 F./93 C.) for around an hour, then remove the hulls by hand. That’s it; you can now cook with your very own home grown, long grain brown rice.

It converges the light in to one point.
What is Flashlight?A portable hand-held electric lighting is known as a flashlight (US, CA), torch (UK), or torch (AU).
The light source used to commonly be a tiny incandescent light bulb, but since the mid-2000s, light-emitting diodes (LEDs) have taken their place. The common components of a flashlight are a light source mounted in a reflector, a clear cover (often paired with a lens) to shield the light source and reflector, a battery, and a switch, all of which are housed in a case.
Around 1899, the development of dry cells and tiny incandescent electric lamps made the first battery-operated flashlights feasible. Today's flashlights run on disposable or rechargeable batteries and typically use light-emitting diodes.

Two football players are running toward each other. One football player has a mass of 105 kg and is running at 8. 6 m/s. The other player has a mass of 90 kg and is running at -9. 0 m/s. What is the momentum of the system after the football players collide? 93 kg · m/s 1,713 kg · m/s. 810 kg · m/s. 903 kg · m/s.
The correct answer is P = 1740 kg · m/s, we got this answer by applying the momentum expression which is P = Δ(mv), based on the fact that the mass is not constant
Given data
Mass of Player one = 105kg
Mass of Player two = 93Kg
The Velocity of Player one = 8.6m/s
The Velocity of Player two = -9.0m/s (the negative sign indicates the opposite direction to player one)
Applying Newton’s Second Law in Terms of Momentum because the mass is not constant
When Newton’s second law is expressed in terms of momentum, it can be used for solving problems where mass varies,
We also want to assume that the players stuck together after the collision
An inelastic collision, in contrast to an elastic collision, is a collision in which kinetic energy is not conserved due to the action of internal friction.
P = M1V1 + M2V2
P= 105*8.6+93*9.0
P = 903 +837

David is a sophomore in high school and is studying for his united states history exam, in which he must recall all of the battles in the american revolutionary war. At first, he begins by just trying to group all of the facts associated with each battle into his memory. When he realizes he is forgetting some battles, he begins repeatedly associating the events that occurred in each battle with the place where the battle occurred. He finds he remembers the battles more readily this way, but he is still having a hard time remembering all the facts associated with each battle. Because he continues to think this is the best way to approach learning, he continues to study in this manner. After several bad grades, he realizes that his studying technique is not working, so he asks a friend who is doing better at remembering everything how she is studying. She said she is making up stories about each battle and how each battle is connected with other battles. David tries this method and finds it was much more effective for him.
People are often influenced by different things that affect their behavior. The concepts that relates to this scenario is explained below.
Metacognition is known to be the act of thinking about one's own thought and learning. David first use a method to remember the battles in the American Revolutionary war, and later on uses an alternative method. He asked a friend when he saw his errors. This shows that David understood his thought process and is trying too control it.
Method of loci is known as a strategy of memory enhancement that uses visualizations to boast e recall of information. David uses this to link the events that happened in each battle with the place where the battle took place.
Deep processing is known as a step taken in processing spectrum of mental recall via examining of language used. David's friend uses stories for each battle and connects it with other battles. David then uses deep processing via examining the battles too.
Rehearsal often uses repetition to remember things. David always practicing boast his remembrance of the battles in the American Revolutionary War.
Elaboration is used to enhance total remembrance. By making up stories about each battle and relates it to other battles, it aid David in learning.
Chunking is known as the act of taking different pieces of information and placing them into larger units. David friends sees each battle as a single unit and then they often link up the different events together.
Mental set is known as the ability of the brain to stick with the most familiar solution to a problem and ignore others. David uses the friends method and apply as it aid remembrance more.

How many grams of lead product would theoretically be produced between 17. 0 g potassium iodide, ki, and 25. 0 g of lead (ii) nitrate, pb(no3)2?.
The number of grams of lead product that would theoretically be produced from the given reaction is; Mass of lead product = 23.6 g
Potassium iodide reacting with Lead(II) Nitrate would yield the balanced equation;
2KI + Pb(NO₃)₂ = 2KNO₃ + PbI₂
2moles : 1 mole = 2 moles : 1 mole
From online tables;
Molar mass of KI = 166 g/mol
Molar mass of Pb(NO₃)₂ = 331.2 g/mol
We are given;
Mass of KI = 17 g
Mass of Pb(NO₃)₂ = 25 g
Thus;
Number of moles of PbI₂ yielded in order to find the limiting reactant will be;
no of moles of PbI₂ from KI = (17g/166 g/mol) × (1 mole of PbI₂/2 mol of KI)
no of moles of PbI₂ from KI = 0.0512 mols
Similarly;
no of moles of PbI₂ from Pb(NO₃)₂ = (25g/331.2 g/mol) × (1 mole of PbI₂/1 mol of Pb(NO₃)₂)
no of moles of PbI₂ from Pb(NO₃)₂ = 0.0755 moles
We can see that KI produced the least amount of moles. Thus;
Mass = 0.0512 * molar mass of PbI₂
From tables, molar mass of PbI₂ = 461 g/mol
Thus;
Mass of lead product = 461 * 0.0512
Mass of lead product = 23.6 g
