1) The diagram below depicts the path of a projectile fired at a speed of 33.1 m/s at an angle of 65 a) Label the x-and y-components of the velocity at each point along the path. Each dot represents the passage of 1
second of time
b) What is the speed of the ball att = 5 seconds?

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
