1 Give three uses of mirrors in everyday life. 2 If you look into a pond or a calm river, you may see a clear reflection of
yourself. What does this tell you about the surface of the water?
3 Make a copy of the diagram showing the law of reflection. Use a ruler
to draw the rays and the mirror: Use a protractor to make sure that you
draw the normal at 90° to the mirror Draw the angles of incidence and
reflection with values of 30°. Label your diagram fully.
4 If a ray of light strikes a mirror with an angle of incidence of 60°, what
will be the angle of reflection? Sketch a diagram of this situation.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.

i think the answer is tomato juice? not entirely sure though
