Hydrogen makes stars and stars spend most of their lifetime making helium.
The heavier elements are made when an old-age, high mass star explodes as a nova or supernova and then dies.
When you hit a hammer on the head of a nail, all the momentum associated with hammer is transferred into nail. And due to this, the surface of nail gets deformed or if you touch it you can feel the rise in temperature. When you hit a hammer on nail, hammer exerts force on nail and by Newton's 3rd law, nail will also exert a force on the hammer perpendicular to the surface of the hammer of same magnitude but its direction will be reversed. Thus, only 2 forces acts in this interaction and they are action-reaction pairs.
Hi there!
a.
The equation for centripetal acceleration is as follows:
Plug in the given values to solve:
b.
According to Newton's Second Law:
The acceleration is v²/r, so the net force is:
Multiply by the given mass:
c.
There is NO net force in the vertical direction since the object is NOT accelerating in the vertical direction (normal force and weight cancel).
Thus, the ONLY net force experienced by the object is in the horizontal direction and is EQUAL to the centripetal force.
Answer: wind pushes directly against the blades of the turbine, which converts the linear motion of the wind into the rotary motion, then it spins the generator's rotor and the harder the wind pushes, the more electrical energy can be generated.
