1.во сколько раз изменится сила взаимодействия тел, если массу одного из них уменьшить в 2 раза, а массу другого увеличить в 3 раза?
2. Определить изменение скорости тела массой 100 грамм, если импульс увеличился на 2кг м/с

• сила притяжения между телами определяется выражением F = (G m M)/r². следовательно, F ~ m и по условию сила увеличится в 3/2 = 1.5 раза

• Δp = m Δv

○Δv = Δp/m = 2/0.1 = 20 м/c

Answer the following questions . • How can people enjoy the drawings today ? • Why did early humans take so much time to paint instead of hunt ? • Why the most depicted animal was horse ?Transcript Mia: Hello, David. Oh hi, Mia. Sorry I'm a bit late. Davi d: Oh. No problem! Thanks for agreeing to help me with my assignment today. I really needed to go over it with someone. Sure. You were going to talk about European rock art, weren't you? Mia: Davi d: Mia: Yes, the rock drawings in the caves of Lascaux in western France. Oh, fantastic, over 13,000 years old, I believe. What sort of drawings are they? They're drawings of animals on the whole, but you can also find some human representations, as well as some signs. There are roughly 600 drawings at Davi d: Mia: Lascaux. Davi Really? Were they mostly pictures of bulls? d: Well, no, actually, the animal most depicted was the horse. Have a look at this Mia: graph. It shows the distribution of the different animals. You see... first the horse. and then after that a sort of prehistoric bull. Oh, OK. That's interesting, isn't it? Davi d: .and the third most commonly drawn creature was the stag. There were Mia: some other animals but these are the main ones. Davi What are the drawings like? I mean, what sort of style? d: Well, the bulls are depicted very figuratively - they're not very realistic. They are very big by comparison to the other drawings, of people and signs. They appear to be almost three-dimensional in some cases, following the contours of the Mia: cave walls, but of course they're not. Amazing. Perhaps they felt these animals were the most impressive and needed to Davi d: be represented like that. Yeah, maybe. The drawings of humans by contrast consist of just simple lines.
