C=Charge(Q)/Change in Voltage

Question 17

Electrostatic PE Equation

Answer 17

Question 18

Doppler Effect

Answer 18

The Doppler Effect arises whenever a source of waves is moving in relation to its observer or an observer is moving in relation to the source of waves. The result is that the waves will have different wavelengths and frequencies than expected. When a source of waves approaches an observer, the waves crunch up meaning that from the observer’s view point, the waves have shorter wavelength and a higher frequency. As a source of waves recedes from an observer, the waves stretch. This means from the observer’s viewpoint the waves have longer wavelength and lower frequency.

Question 19

Frequency, Wavelength, and the Speed of Light

Answer 19

Question 20

1 eV (electronvolt) = x Joules

Answer 20

1.6x10^-19 J

In physics, an electronvolt is the amount of kinetic energy gained (or lost) by a single electron accelerating from rest through an electric potential difference of one volt in vacuum.

Question 21

Alpha Particle Charge

Answer 21

1.6x10^-19 J x 2 electronic units

Question 22

Torque

Answer 22

a twisting force that tends to cause rotation.

Question 23

PE_grav=

Answer 23

mgh

Question 24

Translational Equilibrium

Answer 24

An object is in translational equilibrium when the sum of all the external forces acting on the object equals zero. This also means an object is in translational equilibrium when it is experiencing zero overall acceleration. Therefore, it is either not moving or moving at a constant velocity.

Question 25

Gauge Pressure

Answer 25

for example, if you have a tire at atmospheric pressure, a gauge measures it as 0; any measurement is a result of a pressure GREATER than the atmospheric pressure. thus:

gauge pressure + atmospheric pressure = total pressure exerted.

Question 26

Wavelength of Red Light

Wavelength of Blue Light

Answer 26

Red light = .0007 mm or 7000 Å

Blue light = .0004 mm or 4000 Å
