(i) A multimeter
(ii) Reads if there is short circuit in the electric circuit
(i)A simple microscope uses one lens while a compound microscope uses two lens
(ii)A compound microscope produces a higher magnification than that of simple microscope
Using M= ZIt
I = M/Zt
I = 450/3.30*10-⁴ *25*60
I = 909A
Range (R) is defined as the horizontal distance from the point of Ohio aprojection to the point where the projectile hits the projection plane again
Time of flight: T= 2usinθ/g
sinθ = Tg/2u = 1.5*10/2*12
sinθ = 15/24 = 0.625
θ = sin-¹(0.625)
θ = 38.7°
(ii)A moving car
mgh = mc∆θ
∆θ = gh/c = 10*108/4200
= 0.257°C or 0.257K
A stationary wave is produced by a superposition of two waves of the frequency and amplitude which are exactly out of phase with each other
Wavelength = 4/2.5 = 1.6m
Vaporization is the conversion of a substance from the liquid or solid phase into the gaseous (vapour) phase.
(ii) No change
Lost Volt refers to the amount of energy lost (in a battery, generally) to energy resistance of components. It is generally fairly negligible, but to calculate: V=IR
where I is the current and R is resistance.
(i) Secondary cell last long and can be used over again and again.
(ii) A secondary cell is rechargeable meaning that the chemical reactions taking place in the cell are reversible and can be carried out in the opposite direction to charge the cell again.
