Answer:62m/s
Explanation:
Initial velocity(u) =12m/s
Acceleration(a)=2.5m/s2
Time(t)=20seconds
Final velocity(v)=?
V=u+axt
V=12+2.5x20
V=12+50
V=62m/s
I'm in middle school, but I think I know the answer, I am sorry if I am wrong.
It's D
Almost all methods of generating electricity depend on using
some other form of energy to spin an electrical generator.
If the other form of energy is kinetic energy robbed from wind,
then the wind turns the blades of a big 'fan', and the blades
spin the electrical generator.
In a commercial windmill, the electrical generator is in that 'box'
on top of the pole, right behind the hub of the blades.
Answer:
Furthermore, the Pythagorean theorem works when the two added vectors are at right angles to one another - such as for adding a north vector and an east vector.
Science like this is being used when it comes to tornados. They have special robots and equipment that travel inside the cone and measure the speed and width of the tornado. This information is processed back to the meterologists and this helps the public get to safety in a split second.
