Suppose you throw a ball vertically downward with a speed of 10 m/s. neglecting air friction what would be the speed of the ball one second later?

What structural formula represents 4 electrons shared between two atoms?

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.

The law of reflection states that the angle of reflection is equal to the angle of
