When a 12V battery (i.e. a battery of EMF 12V) is connected across a lamp with a resistance of 6.8 Ω the PD across the lamp is 10.2V. Find (a) the current through the lamp, (b) the internal resistance of the battery.
What is Lorentz number? The thermal and electrical conductivities of Cu at 20oC are 390 Wm-1K-1 and
5.87x107W-1m-1 respectively. Calculate Lorentz number.
Which of the following is an equivalent expression to sin θ − (sin θ)(cos2θ)?

At what temperature will 4.15g of CO2 exert a pressure of 855 mmHg at a volume of 650 ml? (make sure to turn grams into moles)
By considering the angles between the vectors, show that a + b and a – b are

A ship captain is plotting a course to an island 80 km SW of his current position.
The wind is blowing from the East at 15 km/h. What must the velocity vector of
the ship be in order for it to arrive at the island in 2 hours (hint: think about what
the resultant velocity must be).
A plane with a velocity 400 km/h, 10 degrees, West of South encounters a wind with a
velocity of 40 km/h, from 35 degrees East of South. What is the plane’s resultant
velocity?
