-acceleration= v-u/t (v=final velocity, u=initial velocity, t=time0

-changing from km/hr to m/s  

• km to metres= x1000
• hr to minutes= x60
• minutes to seconds= x60

-if there is an earth wire in an appliance then it is safe to use.

-resistance is measured in ohms

-electromagnetic spectrum are all transverse waves and they travel at the speed of light.

- equation relating critical angle and refractive index is

• sinC=1/n
