Answer:
"A turbine takes the kinetic energy of a moving fluid, air in this case, and converts it to a rotary motion. As wind moves past the blades of a wind turbine, it moves or rotates the blades. These blades turn a generator."
Answer:
304.86 metres
Explanation:
The x and y cordinates are 
and 
respectively
The horizontal distance travelled, 
Making t the subject, 
Since 
, we substitute t with the above and obtain
Making d the subject we obtain
d=304.8584
d=304.86m
<span>The correct answer is: Chlorofluorocarbons (CFCs)
Explanation:
In simple words, CFCs are the chemical compounds made up of the following three elements:
1. Carbon
2. Chlorine
3. Fluorine
When CFCs compounds reach the upper atmosphere, the ultraviolet rays coming from the Sun break those compounds into individual elements, which then react with one of the oxygen atom of the ozone (O3) to form new compounds like chlorine monoxides. That way the ozone molecules get destroyed, resulting into the ozone depletion. Hence, the correct answer is Chlorofluorocarbons (CFCs).</span>
The car accelerates with magnitude <em>a</em> such that
31.3 m/s = 25.6 m/s + <em>a</em> (5.4 s)
→ <em>a</em> = (31.3 m/s - 25.6 m/s) / (5.4 s) ≈ 1.056 m/s²
Then the applied force has a magnitude <em>F</em> of
<em>F</em> = (1430 kg) <em>a</em> ≈ 1500 N
<span>F = Gm1m2 / r^2
if the masses are doubled then the force is increased by a factor of 4
if the distance is doubled the force is decreased by a factor of 1/ 2^2
the net result is no change in force</span>
