question options:

1

2

3

4

question 4

question options:

cobalt, sodium and mercury

iron, cobalt, and nickel

nickel, mercury and sodium

sodium, cobalt and iron

question 5

the movement or spinning of this subatomic particle is what creates magnetism.

question options:

protons

neutrons

electrons

quarks

question 6

true or false: magnets are weakest at their poles.

question options:

true

false

question 7

are devices that create a magnetic field through the application of electricity.

question options:

motors

electromagnets

generators

magnets

question 8

true or false: electromagnets are beneficial because they can be turned on and off.

question options:

true

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.

One day, after pulling down your window shade, you notice that sunlight is passing through a pinhole in the shade and making a small patch of light on the far wall. you see that the patch of light seems to be a circular diffraction pattern. it appears that the central maximum is about 1 cm across and you estimate that the distance from the window shade to the wall is about 3 m. what is (a) the average wavelength of sunlight? (b) the diameter of the pinhole?

The magnitude of the amount of energy released by burning a fuel source, measured in energy per unit mass, is called its fuel value. note that the fuel value is the negative of the isobaric specific heat of combustion for the fuel. if all the energy obtained from burning 1.23 pounds of butane with a fuel value of 10.85 kcal/g is used to heat 128.0 kg of water at an initial temperature of 18.3 °c, what is the final temperature? note that 1 lb = 453.6 g.
