Questions & Answers
what is a principal wave?
A wave the movement of particles on rest position transferring energy from one place to another
Gabche
not wave. i need to know principal wave or waves.
Haider
principle wave is a superposition of wave when two or more waves meet at a point , whose amplitude is the algebraic sum of the amplitude of the waves
arshad
kindly define principal wave
not principle wave (principle of super position)
if u can understand my question
Haider
why are electros emitted only when the frequency of the incident radiation is greater than a certain value
b/c u have to know that for emission of electron need specific amount of energy which are gain by electron for emission . if incident rays have that amount of energy electron can be emitted, otherwise no way.

states that electric current in a given metallic conductor is directly proportional to the potential difference applied between its end, provided that the temperature of the conductor and other physical factors such as length and crosssectional area remains constant.
mathematically
V=IR

A body travelling at a velocity of 30ms^1 in a straight line is brought to rest by application of brakes. if it covers a distance of 100m during this period, find the retardation.
just use v^2u^2=2as
Gundala
how often does electrolyte emits?
alhassan
just use +€^3.7°√π%4¢•∆¥%
v^2u^2=2as
v=0,u=30,s=100
30^2=2a*100
900=200a
a=900/200
a=4.5m/s^2

what is distribution of trade
The change in position of an object with respect to time
Mfizi
Acceleration is velocity all over time
Pamilerin
It's not
It's the change of velocity relative to time
Laura
Velocity is the change of position relative to time
Laura
acceleration it is the rate of change in velocity with time
Stephen
acceleration is change in velocity per rate of time
Noara
what is ohm's law
Stephen
Ohm's law is related to resistance by which volatge is the multiplication of current and resistance ( U=RI)
Laura
acceleration is the rate of change. of displacement with time.
Radical
the rate of change of velocity is called acceleration
Asma
how do I access the Multiple Choice Questions? the button never works and the essay one doesn't either
How do you determine the magnitude of force
mass × acceleration OR
Work done ÷ distance
Seema
Which eye defect is corrected by a lens having different curvatures in two perpendicular directions?
the difference between virtual work and virtual displacement
How do you calculate uncertainties
the property of a body to regain it's original shape is called elasticity.
or. the property of a body which can be stretch is called elasticity.
