This is physics, electricity.
I'll break it down for you, very easy:
you have to use the formula V=IR
where V= voltage in volts (V)
I= current in Amperes (A)
R= resistance in ohms (Ω)
so what you require is I, current there you have to rearrange the formula to subject current;
I=V/R
=9/5= 1.8Ω (ans)
Answer:
False
Explanation:
Humans:
Nitrogen is represented by the symbol N. It is abundant in the environment but humans can't use it directly from air or soil but depends upon green plants and microbes to convert it in to the usable form for using it
Plants:
Plants do not get their nitrogen directly from the air. Although nitrogen is the most abundant element in the air, every nitrogen atom in the air is triple-bonded to another nitrogen atom to form molecular nitrogen, N2
i think it would be 105 or more but i know they have the same
A. changes in the Moon's visibility
Answer:
<u>Oxbow lake is formed when a bend in a river is cut off to form a lake.</u>
Explanation:
- <u>OPTON A - It is formed as lakes grow larger due to erosion and begins to look like an ox. </u>
This statement is incorrect , as the shape of the oxbow lake is not like an ox , it is a <u>horse-shoe shaped lake .</u>
- <u>OPTION B - It is formed when a bend in a river is cut off to form a lake.</u>
This statement is correct , as An oxbow lake is a U-shaped lake that forms to create a free-standing body of water when a large meander of a river is cut off.
- <u>OPTION C - It is formed when a delta grows large enough to cut off a river to form a lake. </u>
This statement is also wrong, as a<u> river delta</u> is specified by this statement.
- <u>OPTION D - It is formed when a dam stops the flow of a river and creates a lake.</u>
This statement is also false, since the creation of a<u> reservoir</u> is established by this statement.
<u>FORMATION OF OXBOW LAKE -</u>:The neck of the meander gets narrower and narrower progressively. The curve gradually grows so close that the river slices through the neck of the meander to take a new, straighter path. Sediment locks the end of the old loop over time. This leaves a region of water that is different, called an oxbow lake.
Hence , <u>the correct option is B.</u>
