I live in Scotland and moved into my property 3 months ago. Having just entered my first meter reading (since the initial one when I entered the property), am being charged £600 for electric! More than twice what I expected! Having conducted some tests, it appears that it's the central heating/thermostat that is faulty and this is what has caused the excessive bill - I'm using 8x as much electric over just 3 hours when the heating is on and all the radiators in the property get very hot, even those on frost setting. Contacted the landlord and they are going to get the thermostat looked at and fixed if needs be, but if it is the central heating that is faulty am I entitled to any money from them to foot the massive electric bill that it has caused? As this was my first electric bill there is no way I could have known earlier and I reported the issue straight away as I'm now having to live with no CH despite the snow. Any advice appreciated :(

I'm actually a biology student and I haven't done any physics since I was in school. Basically we did an experiment using something called a 'force transducer' which apparently converts force into a voltage output, and this was then mapped on a graph against time by a computer.

We used plasticine balls to calibrate the transducer by attaching them via a string, holding then, and then dropping them when the transducer started measuring to produce a voltage value when the string got yanked, and repeated that for different weights.

What I want to know is, how to I convert voltage back to force? I know the mass of the plasticine balls, and the voltage they produced... I know that usually force is calculated using F=ma, but how do I know what the acceleration is? Is it something do do with the gravity acting on the ball of plasticine?

It's probably something simple but I can't get my head around it. I'm really confused...
