The surface area of the laboratory bench is 4.16 metre square. Explain why this area is called a derived quantity.​

Picture a all traveling at a constant speed around the inside of a circular structure. is the ball accelerating? explain your answer

If the new moon happens on january 15th, what shape will it be on february 6th?

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.
