MSA Flashcards
Plack’s constant
6.63 x 10-34 J•s
Photoelectric effect formula
E= hf
Rate of doing work
Give the formula
Power
P = W / t
Momentum formula
P=mv
M- mass
V- velocity
Change in the momentum of a moving obejct
Impulse
Efficiency formula
% e = work output/ work input x 100
Lowest to highest energy of visible light
ROYGBIV
Heat energy formula
Q= mLf
Q- amt of heat absorbed (joule or calorie)
M- mass (gram or kg)
Lf- latent heat fusion
Formula of Work
W= Fd
Force exerted by molecules of air on a body of a falling object
Air resistance/ air drag
Radioactive decay process in wc an unstable nucleus splits into two fragments of comparable mass often producing free neutrons and photons & release very large amt of energy
Nuclear fission
In a PARALLEL circuit, the voltage (electric potential difference) accross all resistors is ????
Same
Doppler effect is a change in frequency of a wave of sound or light due to the motion of the source or the receiver
If the moving source - ?
If stationary- ?
If a moving source is approaching the listener, the frequency of the sound is higher that when the source is stationary
Use positive in the numerator when
Negative
Denominator
Positive
Negative
- toward the source
- moves away from the source
- away from the observer
- toward
Einstein’s formula
E = mc2
C- 3x10(8) ms
Explains that any object immersed in a fluid is pushed upward. The upward force is called buoyant force.
Archimedes’ principle
Pressure applied to an enclosed fluid is transmitted to every portion of fluid and the walls of containing vessel
Pascal’s principle
Current was produced with the use of a magnet not with batteries
Induced emf / Faraday’s law of electromagnetic induction
As elevator moves upward
W on scale > actual weight
As elevator moves downward
W on scale < actual wt
Explain
Explain pressure relationship with F and A
P - direct with F
Indirect with A
The smaller the space, the more it collides, the more force so more pressure
Force between two objects
Gravitational force
Force responsible for radioactive decay
Weak nuclear force
Force of attraction or repulsion between charged particles
Electromagnetic force
Force that holds proton and neutron together
Strongest force
Strong nuclear force
