Answer:
I guess the answer is charging by friction
Answer:
549 gallons
Explanation:
1 gallon of radioactive material was added to unknown volume of gasoline which we will represent as V in gallons.
Initially the 1 gallon gives a 5500 counts per minutes (cpm)
After adding to an underground gasoline tank, the total volume becomes
(V + 1) gallons
1 gallon was withdrawn from the underground and gave 10 cpm
using simple proportion and assuming the gasoline has mixed together
1 gallon gave 10 cpm
10 (V + 1) gallons should give 5500cpm
10 (V+1) = 5500cpm
divide both side by 10
V+1 = 5500 /10 = 550
V = 550 -1 = 549 gallons
Answer: Strength of magnet and distance from magnetic material
Explanation:
The potential energy of a magnet is determined by the strength of the magnet and the distance between a magnet and another magnet or a magnetic material. Magnetic materials are materials that would be attracted when brought close to a magnet, example of magnetic materials are most metals.
An example helps clarify the difference between an analysis, a deter- mination and ... departments analyze samples of water to determine the concentration of ... moles of Cu2+, and cylinder 2 contains 20 mL, or 2.0 × 10.
