Pressure=force/area therefore pressure is inversely proportional to the area if the force is constant. As a result the pressure will be greater.
Answer:
Explanation:
For resistances in parallel we know that the overall resistance will be smaller in the value than any individual resistance. so, in this case we are concerned about
=
⁺ 
where Rs is the series resistor and Rp is the parallel resistor.
so, R = 0.9M, roughly.
So, as the infernal resistance is very high as compared to the resistance conntected in parallel that is 100 Ω is not be used.

The total momentum of the system has to be conserved to satisfy the principle of conservation of momentum. Before the ball hits the bottle, the momentum of the system is 0.4 x 18 = 7.2 kg m/s
The momentum of the bottle after being hit is 0.2 x 25 = 5 kg m/s
So the momentum of the ball now is 7.2 - 5 = 2.2 kg m/s
Hence its velocity is 2.2/0.4 = 5.5 m/s
