Answer:
1.86 s
Explanation:
Given the expression
h(t) = -16t²+ 64...................... Equation 1
Where h = height of the object, t = time it will take the object to hit the ground.
Given: h = 64 foot.
We have to concert from foot to meters
If 1 foot = 0.3048 meters
Then, 64 foot = 0.3048×64 = 19.51 meters.
We substitute the value of h into equation
119.51 = -16t²+64
-16t² = 199.51-64
-16t² = 55.51
t² = 55.51/-16
t² = 3.469
t = √3.469
t = 1.86 s.
Hence it will take the object 1.86 s to hit the ground.
Advantages of using tidal power include no air pollution, no air pollution and low environmental impact.
<h3>What is Tidal Power?</h3>
The rush of ocean waters during tide changes is what generates tidal energy. A renewable energy source is tidal energy.
In places with a wide tidal range—the distance between high tide and low tide—engineers devised methods to harness tidal movement to generate power during the 20th century. Each technique turns tidal energy into electricity using specialised generators.
Production of tidal energy is still in its infancy. So yet, hardly much electricity has been generated. There aren't many commercial-scale tidal power facilities in operation worldwide. The first was at France's La Rance. The Sihwa Lake Tidal Power Station in South Korea is the biggest facility. There are very few places in the United States where tidal energy might be generated at a competitive price and no tidal plants. Russia, Canada, France, England, and China have the most potential for using this kind of energy.

B.
carbon dioxide molecules have more energy; therefore, the kinetic energy increases
