What is the relationship between speed, distance and time?
Speed = distance/time
Speed= distance x time
Distance= speed x time
Speed= time
What is the relationship between velocity , timetaken and accelaration ?
A = (v-u) / t
Acceleration = velocity * timetaken
A= v-t
Acceleration = change in velocity / time taken
What is the relationship between pressure, force and area?
Pressure = force * area
Area = pressure - force
Pressure= force / area
Area = force / area
What is the relationship between weight, mass and gravitational field strength?
Weight = mass / gravitational field strength
W = mg
Weight= mass x gravitational field strength
W =m/g
Density is
(a)
State the relationship between work done, power, time taken?
Workdone= timetaken - power
Workdone = power - time taken
Power = workdone / time taken
Velocity = frequency x wavelength
True
False
Efficiency = energy converted to the required form / total energy input
True
False
Power = workdone /time taken
True
False
Thermal energy =
Mass x heat capacity
Mass x change in temperature
Mass x specific heat capacity x change in temperature
Mass + specific heat capacity/ change in temperature
Which relationship is incorrect?
Current = charge + time
Deceleration = loss in velocity/ time taken
Force = mass x acceleration
Efficiency= power output / power input * 100%
What is displacement?
G.P.E = mgh
Gravitational potential energy = mass x gravitational acceleration x vertical height
Gravitational potential energy = mass x gravity x height
Equation given above is incorrect

According to Charles law, for a fixed mass of gas at the constant pressure, the volume occupied by the gas is (a)
State the relationship between charge, current and time
Charge = current/ time
Q=T/I
Q = I t
Charge = current x time
Angle of incidence ≠ angle of reflection. True or false?
True
False
