Make a the subject of the formula s=ut + 1/2at^2

What's needed to know Right now we are doing unit 1 which is about tensions in ropes and weight and stuff about newtons. We are taking a test tomorrow and I studyed in the book. What is the main stuff I need to know for tomorrow

Which of the following wave types has a wavelength closest to visible light? Gamma rays, Infrared rays, Radio, or Microwaves

Planetary orbits around a star can be modeled with the following potentialU (r) = ar+br2 (1) (a) Show that the equilibrium position for this potential is equal tore = 2b=a.

Why aren't renewable resources used for everything that we use energy for?

A 96lb boy is standing in an elevator. Find the force on the boy's feet when the elevator (a) stands still (b) moves downward at a constant velocity of 3 ft/d (c) accelerates downward with an acceleration of 4.

In an experiment to measure the acceleration due to gravity, g two values, 9.72 m/s2 and 9.67 m/s2, as determined. if the accepted value of g is: 9.8 m/s2 find the followings: i) the percentage difference of the measurements?

If momentum is conserved in a collision, does this indicate conclusively that the collision is elastic?

The acceleration of gravity means that for each second that passes, falling objects move 9.8 meters. A. True B. False

Explain, using numbered steps, how you could find the volume of a small, irregularly shaped rock.
