QuestionAnswer
Law of conservation of momentum Total momentum befor=total momentum after IN THE ABSENCE OF EXTERNAL FORCES
Acceleration is... change in velocity per unit time
Elastic collision Momentum and kinetic E are stored
Inelastic collision Momentum is conserved kinetic E is lost
Impulse= area under F/t graph = change in momentum
1cm^3= 1x10^-6m^3
1cm^2= 1x10^-4m^-2
1 Volt= 1J/C
Lost volts= Ir = E-V
I short circuit= E/r
I stays the same for... all frequencies for a resistor
In an ideal op-amp... input I 0 (infinite input R) no V between invertiing and non-inverting inputs (both input pins at same V)
Op-amps saturate when... V > 85% of supply V
In the photoelectric effect, discharge only occurs if... Zinc metal plate, UV light, AND -ve charge
E1= work function
f0= threshold f
D= absorbed dose
H= equivalent dose
A capacitor can block... d.c.
When the distance between slits in a grating increases... distance between maxima on screen decreases
Intensity= Js^-1m^-2
n-type and p-typ are... electrically neutral
In fission______ are released. neutrons
In a capacitor circuit, if f increases... I increases
If critical angle is smaller than angle of incidence... total internal reflection
Newton's 3rd law Equal and opposite force
To increase the distance between fringes on a screen... use light of lower f
