One wave pulse occurs at a certain point every three seconds. Which property of the wave is this measure?

Frequency

Explanation:

If your measuring wave length then you would use Frequency.

Hope this helps!

X

Explanation:X

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

32: from largest to smallest, this hierarchy includes eons, eras, periods, epochs, and ages.

33: answer is c
