Describe how a wind turbine generates energy.
Artyom0805 [142]
The wind Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity.

By what distance do two objects carrying 1.0 C of charge each have to be separated before the electric force exerted on each obj
NNADVOKAT [17]

Answer:

Distance between both the object will be 404.51 m

Explanation:  

We have given charge on two objects q_1=q_2=1C

Coulomb force between the two objects is given F = 5.5 N

We have to fond the distance between both the object so that force between them is 5.5 N

According to coulomb law force between two charge particle is F=\frac{1}{4\pi \epsilon _0}\frac{q_1q_2}{r^2}

So 5.5=\frac{9\times 10^9\times 1\times 1}{r^2}

r^2=16.36\times 10^8

r = 404.51 m

So distance between both object will be 404.51 m

A pitcher throws a baseball towards home plate. The baseball, which has a mass of 142 g, approaches the plate with 128 J of kine
mylen [45]
Mass=142g
K.E=128 J
Speed or Velocity=?
K.E=1/2*m*v^2
128=1/2*142*v^2
128=72*v^2
v^2=128/72
v^2=1.777
by taking square rt 
v= 1.333ms-1
so the speed will be 1.333 ms-1
