What kind of object is emitted in the decay of 40K?

40^K -> 40^Ar + ?

Back 1

A Positron
(Beta Plus)

Front 2

Increasing the frequency of each photon that is directed at the cathode will:

Back 2

Increase the speed of the ejected electrons

Front 3

As the speed of the jet flying away from the receiver increases, what happens to the distance between adjacent peaks of the transmitted waves, as measured at the receiver?

Back 3

It Increases

Front 4

A constant acceleration:

Back 4

will increase
the velocity at a linear rate

Front 5

Key differences between sound waves and radio waves

Back 5

Radio Waves travel at the speed of light, Sound waves travel much slower than radio waves. ~340m/s in air and their speed varies with the medium through which they travel

Front 6

formula that relates pressure with
the acceleration of gravity and depth

Back 6

P = ρgz, where P is the pressure, ρ is the density of the liquid, g
is the acceleration due to gravity, and z is the depth under the liquid as measured from the surface

Front 7

Melting

Back 7

While the temperatures of the solid and the melted
liquid increase as the temperature increases, during the actual melting process, the input heat is used to break
the intermolecular bonds in the solid so as to form a liquid. As such, during that brief period in which the solid
melts, the temperature of the substance remains constant until all of it is melted

Front 8

a pipe open at both ends with a length of 1 m and a
diameter of 0.1 m,determine the fundamental wavelength

Back 8

Fundamental Wavelength:

= 2L/n

Front 9

properties of mechanical waves

Back 9

mechanical waves only transport energy, not matter

Front 10

Equation to find the final velocity in a totally inelastic collision

Back 10

vf =
(m1v1 +m2v2) / (m 1 + m2)

Front 11

Equation: Power in a circuit

Back 11

P = IV = (V^2)/R = (I^2)R

Front 12

Photoelectric Effect: What happens to the electron when the energy of the incident photon increases?

Back 12

An increase in the photon’s energy means that more energy will be transferred to the electron,
making the kinetic energy, and thus speed, of the electron higher.
