false
question 9
the earth has a protective magnetic field around it, that is created by
question options:
the upward motion of mountain chains forming.
molten iron in the earth's core.
molten iron in volcanoes.
the movement of tectonic plates.
question 10
true or false: doorbells, scrap yards, and rock concerts are all examples of every day uses of electromagnets.
question options:
true
false
question 11
true or false: electromagnets cannot lift heavy objects.
question options:
true
false
question 12
looking that following diagram of bar magnets, determine if the magnets will or will not connect (attract) and why.
barmagnet
question options:
they will connect because the like poles are facing each other, and like poles attract.
they will connect because the different poles are facing each other, and different poles attract.
they will not connect because like poles are facing each other, and like poles repel each other.
they will not connect because different poles are facing each other, and different poles repel each other.
are my answers correct before i submit these:
1. unlike or different poles
2. magnetic fields
3. 2
4. iron, cobalt, and nickel
5. electrons
6. false
7. electromagnets
8. true
9. molten iron in the earth's core.
10. true
11. false
12. they will not connect because like poles are facing each other, and like poles repel each other.

Awind turbine is initially spinning at a constant angular speed. as the wind's strength gradually increases, the turbine experiences a constant angular acceleration 0.173 rad/s2. after making 2870 revolutions, its angular speed is 132 rad/s. (a) what is the initial angular velocity of the turbine? (b) how much time elapses while the turbine is speeding up?
