Answer:
Explanation:
A turbine and generator produce the electricity
"A hydraulic turbine converts the energy of flowing water into mechanical energy. A hydroelectric generator converts this mechanical energy into electricity.
Answer:
E.)none of the above
Explanation:
Elastic energy = kinetic energy
½ kx² = ½ mv²
v = x √(k / m)
v = 0.2 m √(20 N/m / 2 kg)
v = 0.632 m/s
Time to travel 2.0 m:
t = (2.0 m) / (0.632 m/s)
t = 3.16 s
Answer:18.29m/s^2
Explanation:
Centripetal acceleration=(velocity)^2÷radius
Centripetal acceleration=(32^2)/56
Centripetal acceleration=(32×32)/56
Centripetal acceleration=1024/56
Centripetal acceleration=18.29m/s^2
Answer:
Is a mixture of all visible light.
Explanation:
The sunlight is a mixture of all colors. Rainbows are light from the sun and are made up of red, orange, yellow, green, blue, violet. The sun produce also ultraviolet waves because of its high temperature.
Answer:
Hi there!
There are many possible answers!
My best guesses are:
1) Knowing how they work will prevent injury! For example, knowing that the gears twist will stop you from putting your finger in it!
2) Allowing you to use it! Knowing how to line up the edge of the can with the tool will let you use it properly!
Hope this helps
