Answer:
Part a)
charge through the battery is
Part b)
Maximum current is
i = 386 A
Explanation:
Part a)
As we know that the rating of battery is given as
here we also know that the charge given by the battery is same as the capacity of the battery
so we will have
Part b)
Now we know that current in the wire is given by
now plug in all values in it
Answer:
When the metal is dropped in the solution it turns blue to green because this forms iron sulphate solution and turns the metal copper
Iron sulphate + copper
Answer:
We need to convert seconds to hours:
5s= (5/60)min= 0.08min=(0.08/60)h=0.001h
a=v/t=36/0.001=36.000km/h^2
Answer:IU (international unit): An international unit (IU) is an internationally accepted amount of a substance.
This type of measure is used for the fat-soluble vitamins (such as vitamins AD and E) and certain hormones, enzymes, and biologicals (such as vaccines).
Explanation:
<h2>Right answer: 2i + 2j and -2i − 2j </h2>
The coordinates of a resulting vector are calculated by <u>algebraically adding the respective components of the vectors</u>.
In other words: to sum two vectors we only have to sum, respectively, the components <em>i</em> and the components <em>j</em> of each vector.
For example, the pair of vectors 2i + 2j and -2i − 2j:
2i + (-2i) = 0i
and
2j + (-2j) = 0j
Then, the resultant is:
0i + 0j
Therefore, the correct option is c.
If we try with the other options, the resultant will<u> not</u> be 0i + 0j:
a. 0i + 0j and 2i − 2j:
2i-2j
b. 2i + 2j and 2i − 2j:
4i-0j
d. 2i + 0j and 0i + 2j:
2i+2j
