Ответ:

a=g

ma=N-mg+k∆

$0.4 \times 10 = 500 \times x \\$

$4 = 500 \times x$

$x = \frac{4}{500}$

$x = 0.008$

ответ: 0,008м и 0,8см

lalalalalallala39: Так там же 2 ответа должно быть

kzarmy613: да 0,008 это в метре , а 0.8 см

lalalalalallala39: Спасибо большое!

Пожалуйста очень срочно надо написать в INDERECT SPEECH IN THE PAST. Это сессия пожалуйста. There's lots of controversy around solar geo-engineering - and for good reason. People are, I think, sensibly scared that this could provide an excuse that allows countries or companies to avoid doing the work that has to be done to cut emissions. But in fact, controversy has really waxed and waned over time, so in the early work on climate change in the 1960s, and 70s and early 80s, these ideas were just part of the way we talked about what might happen about climate change. And then, as climate change became more politically central, say in the 90s and 2000s, there was really a taboo. Neil David Keith believes that geo-engineering could provide an excuse for inaction on climate change – a reason for countries to explain why they did not take action. Sam He says controversy over the method has waxed and waned - an idiom connected with the cycle of the moon which describes something that increases then decreases over time. In the 1960s for example, geo-engineering was uncontroversial, but by the 1990s it had become taboo - a subject that is avoided for social or religious reasons. Neil While these ideas to change the weather have potential benefits, other suggestions - for example to position a giant floating mirror between the earth and sun - are highly controversial… Although personally, I think the idea of giant floating umbrella above Britain would be good! Sam Ha! Well, just think - there are even rainier places to live Neil, as I asked in my question: in which country is the world’s rainiest village? Neil I guessed it was in Ireland. Sam Which was… the wrong answer, I’m afraid. In fact, Mawsynram, the world’s wettest village, is in the Khasi hills of north-eastern India. With around twelve metres of rain a year, I guess it’s not somewhere you’ll be visiting, Neil! OK, let’s recap the vocabulary we’ve learned starting with drizzling which means raining lightly. Neil If you’re meddling you’re trying to change something which is not your responsibility or without being asked to. Sam Someone who is playing God is acting as if they control everything and can do whatever they want. Neil An excuse is a reason you give to explain why you did something wrong. Sam If something waxed and waned, it grew stronger then weaker over time. Neil And finally, a taboo is a subject that avoided for social or religious reasons. Once again, our six minutes are up! Bye for now! Sam Bye!
