1. ### Can anyone answer this CXC past paper physics question on pressure in liquids and u tubes?

(i) The variation in pressure with depth is P = rho * g * h. You've been given P, g and rho, so just plug them in and solve for h. (ii) It's balanced. It's in equilibrium. The unknown liquid is pushing...

2. ### In the equation E=MC2, why is the speed of light squared ( CxC )?

Rockerbo... is right one cannot ask questions regarding fundamental laws. If E has to be expressed as product of mas multiplied by something to balance the dimensions velocity squared...

3. ### No current flows when someone touches just ONE terminal of a 12 V car battery. Explain This fact.?

In car battery, one terminal, preferably the negative one is grounded with the car's body, by connecting a wire to the body's metal frame. Thus you need to carry only one wire from the positive terminal, through switches, fuses, etc for different purposes...

5. ### At what frequency should the generator be operated to provide a maximum current of 2.3 A?

XC=E/I= 58/2.3= 25.22Ω XC=1/ωC -> f=1/(2π CXC ) f= 1/(2*3.1416*5.1*10^-8*25.22)= 123738.5[Hz] approx

7. ### DID MATTER IS CREATED BY LIGHT?

Yes, energy can be converted into matter, but it has nothing to do with traveling at the square of the speed of light!! Nothing can achieve nor pass the speed of light, and thus neither the square of this speed, evidently. This is evident since if matter can be...
