im doing a presentation on the death penalty in the uk what are peoples view and why?

I've been in a relationship with my girlfriend for 26 months now I'm 27 years old and everything is perfect, until one day her sister accidentally walked in on me getting out of the shower, it was a bit awkward and that was it. The other day I came home and it was just her (she lives with me and my girlfriend because her parents aren't very nice) she said my sister was coming home in about 10 minutes and she had left me a note upstairs. On the note it said to strip naked and put on a blindfold and sit on our bed. I heard someone come in a few mins after I'd done this and they started playing with me, then they started giving me oral sex after about 10 mins of this I took off the blindfold and it was my girlfriends sister, I didn't know how to react. I was shocked and tried to leave but she begged me to stay, I am attracted to her and I don't know why but I stayed and we had sex etc, this was 2 weeks ago and my girlfriend has no idea and now my girlfriends sister is threatening me saying I have to keep having sex with her or else she'll tell my girlfriend, help what do I do?

this came up on a practice paper any help me pklease

(i) A brass bar has a length of 1.5 metres at 20°C. What is the increase in length of the bar at 100°C if the coefficient of linear expansion of brass is 19.5x10¯6 /° C?

(ii) Calculate the heat energy required to change10kg of ice at −5°C to water at 0°C. The specific heat capacity of ice is 2.1 kJkgˉ¹Kˉ¹ and the specific latent heat of fusion is 335 kJkgˉ¹ .

Some help would be appritated dont understand them and there on my practise paper
