Answer:
The direction in which a positive charge would move.
Explanation:
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
So,
The conversion factor is:

So, if we plug in the numbers, we get:

Multiply

Add 32

5500 degrees Celsius = 9932 degrees Farenheit.
Answer:
Explanation:
In a sonometer , expression for speed of wave produced can be given as follows .
v = 
v is velocity , T is tension in wire , m is density per unit length .
Here v is inversely proportional to square root of m . So if m becomes m / 4
velocity changes as follows .
velocity = 
= 
= 2v
velocity becomes two times . Hence to make velocity two times , mass per unit length has to be changed to one fourth value , keeping tension constant .
