When gas hydrates are brought to the surface, they evaporate quickly. This would be the biggest, current disadvantage to using gas hydrates as a form of energy.
I believe this battery is called Sheet battery.
Sheet battery is a flexible, ultra thin energy storage and production device formed by combining nano tubes with a conventional sheet of cellulose based paper. It acts as both a high-energy battery and super-capacitor, combining two components that are separate in traditional electronics.
Answer:
<em>The car took 3 hours to travel 180 miles</em>
Explanation:
<u>Constant Speed Motion</u>
An object travels at constant speed if the ratio of the distance traveled by the time taken is constant.
Expressed in a simple equation, we have:

Where
v = Speed of the object
d = Distance traveled
t = Time taken to travel d.
From the equation above, we can solve for t:

The car travels at v=60 mi/h for a distance of d=180 miles. The time taken is:

t = 3 hours
The car took 3 hours to travel 180 miles
Answer:
