Ok I'll come late over here 
e.g parachute falling in the air...it initially accelerates because of Weight>air resistance....as air resistance increases its speed begins to decrease...nd as air resistance>weight...the resultant force is in the direction of air resistance so the object accelerates no more and decelerates....the direction of acceleration becomes negative...opposite to the direction of velocity...(resultant force and acceleration in the same direction)

32. Remember the question states that there are 12 wires in parallel, so try again.
33. Use I^2R is equal to Power, and remember to use the Resistence as 6.5 Ohms. And I is 20V/(6.5+1.5).
Hoot hoot brotheraxe. Ask more.

40. Remember that an Alpha particle reduces the Atomic number by 2 and the mass by 4. So you will first get 223,87. A beta particle, when emitted, increases the number by 1. so Answer is B

Q36. Please answer as soon as possible
Q36. Please answer as soon as possible
Q32= rmmbr kivchoffs law current entering the junction =current leaving a junction...so I1=I2+I3
Q33=for voltage to vary across a lamp..the potential divider shall be connected in parallel to the bulb..(look at the figures carefully)
