6. People aren’t realizing that the earth is in danger.

Going green
In Britain today all political parties are trying to encourage more young people to get involved in politics. This means talking about the issues that are important to them.
The first political party to make the environment an important issue was The Green Party. The party has existed in the UK for about 30 years. (For the first ten years, it was called the Ecology Party.) The Greens do not have any seats in the House of Commons because in general elections most people vote for the three main parties: Labour, the Conservatives and the Liberal Democrats. However, they have several MEPs (Members of the European Parliament) and many local councilors across Britain. They campaign on many issues, including:
• animal rights: they want to ban scientific experiments on animals and improve conditions for animals on farms.
• transport: they want to reduce the amount of traffic and pollution by making buses and trains cheaper, and by encouraging people to walk and cycle more.
• green energy: they want to invest in clean, renewable sources of energy - wind farms, wave and solar power.
• food and farming: they are against GM (genetically modified) food and the use of chemicals in farming.
Twenty years ago, politicians who weren't in the Green Party hardly ever talked about 'green' issues like recycling, renewable energy and climate change. But today, all political parties have 'green' policies. People are realizing that the earth is in danger. If we don't change our way of life, the results will be disastrous for our planet.

СРОЧНЯК ПАЦАНЫ! ДОФИГА БАЛЛОВ 
Для измерения энергии микрочастиц используют системную единицу - электрон-вольт (эВ). Такую энергию приобретает электрон, пройдя разность потенциалов 1 В. Какую кинетическую энергию приобрел электрон, пройдя ускоряющую разность потенциалов 2кВ??

 

Желательно через дано :О

 

Вот формулы по которым она должна решаться(точнее какаято одна из них):

A=q*(ф2-ф1)=qU
E=Ud
C=qU=e0*e*sd

W=q^22C
