b. The atomic mass number would decrease by 4.

b. What happens to its atomic mass number?

b. The atomic mass number stays the same.

b. What happens to its atomic mass number?

b. It becomes Protactinium.

b. What if it emits a beta particle?

b. The product of voltage and current in the primary is equal to the product of voltage and current in the secondary.

b. How does the product of voltage and current in the primary compare with the product of voltage and current in the secondary?

9 V/ 1= 36 V/4

12 V / 1= ? V/4

Vsecondary = 48 V

120 V/ 500 turns = 12 V/ ? turns

# of secondary turns = 50

P=(9.5)(1.2)

P=11.4 W

Law of Universal Gravitation: F= G(m1m2)/r^2

Coulomb’s law allows for attraction and repulsion and gravitation is only attraction. both forces are dependent on the square of the distance between them. Both have a constant.

I= q/t

I= 10/5

I=2 amperes

I = 240/60

I = 4 amperes

0.4=3/R

R= 7.5 ohms

b. There will be more voltage across each lamp if they are connected in parallel.

b. In which case will there be more voltage across each lamp?

b. Charging by induction requires no touching.

b. Which method involves no touching?

b. Yes, electrical fields can be shielded.

b. Can electric fields be shielded?

Electric potential = 12 J / 0.001 C

Electric potential = 12000 V

b. The principle of conservation of energy says that the energy released will be equal to the energy put into the system, so the kinetic energy of the charge as it flies back past its starting point will be 12 J.

b. When the charge is released, what will be its kinetic energy as it flies back past its starting point A? What principle guides your answer?

b) A diverging lens will never produce a real image.

(b) What condition must exist for a diverging lens to produce a real image?

b) This spreading is called diffraction.

b. What is the spreading called?

1/o + 1/I = 1/f

1/80 + 1/40 = 1/f

f = 26.7

You should also indicate the direction of increasing frequency and the direction of increasing wavelength.

b. The photon is more consistent with the particle theory.

b. Which theory of light is the photon more consistent with- the wave theory or the particle theory?

b. It absorbs all other frequencies.

b. What color(s) does it absorb?

Frequency = 1/period Period = 1/ Frequency

b. For each degree increase in air temperature above 0 degrees C, the speed of sound in air decreases by 60 m/s.

b. How does air temperature affect the speed of sound?

frequency = 1/period = 1/0.79 s = 1.27

The period is 0.79 seconds and the frequency is 1.27 Hz.

frequency = wave/s = 10/30 = 0.3 Hz

wavelength = 5m

wave speed = wavelength x frequency = 5m x 0.3s = 1.5 m/s

340 m/s = (20Hz)λ

λ = 17 m

340 m/s = (20000Hz)λ

λ = 0.017 m

1530 m/s = d/4

6120 m = d
