When a high-power laser is used in the Earth's atmosphere, the electric field associated with the laser beam can ionize the air,
turning it into a conducting plasma that reflects the laser light. In dry air at 0°C and 1 atm, electric breakdown occurs for fields with amplitudes above about 3.00 MV/m.
(a) What laser beam intensity will produce such a field?
W/m2
(b) At this maximum intensity, what power can be delivered in a cylindrical beam of diameter 3.44 mm?

Explanation:
Given:
1 can of concentrate requires 3 cans of water
Now,
Total ounces in 200 6-ounce cans = 1200 ounces
also,
for 1 can of concentrate requires 3 cans of water
thus,
for 12 ounces can water can required = 3 × 12 ounces = 36 ounces of cans
Thus,
total ounce of juice per can = 12 + 36 = 48 ounces per can
therefore,
the number of 12-ounce cans required are =
or
=
or
the number of 12-ounce cans required are = 25
