Answer:
2%
Explanation:
Original mass of water in glass = 10 ounces
amount that evaporates each day = 0.01 ounce
number of days = 20 days
Total amount that evaporated = 0.01 x 20 = 0.2 ounce
percentage of water that evaporated during this period = 0.2/10 x 100
= 2%
<em>Hence, the percentage of the original amount of water evaporated during this period is 2%</em>
Answer:
the answer is
0.1342 mL

Electromagnet is a type of magnet which is produced by passing electric current through a magnetic material such as iron. Here electric energy is converted to magnetic energy. The magnetic material is coiled with wire through which electric current is passed. Increasing the number of coils and increasing the strength of the current increases the strength of the electromagnet. However, the electromagnet loses its magnetic properties when the current flow is switched off.
(Answer) (1) Increase the number of coils and increase the strength of the current.
