Two alpha particles (helium nuclei), each consisting of two protons and two neutrons, have an electrical potential energy of 6.11 × 10^?19 J. What is the distance between these particles at this time? The Coulomb constant is 8.98755 × 10^9 N · m^2/C^2, the elemental charge is 1.6021 × 10^?19 C, and the acceleration due to gravity is 9.8 m/s^2.
Now, as both pipes vibrate at their fundamental frequencies, the beat frequency of 17 Hz is heard. How many centimeters were cut off the end of the second pipe? The speed of sound is 333 m/s.
What are the size and direction of the change in velocity if the initial velocity is 6 m/s south and the final velocity is 2 m/s west?
Find the magnitude of book's velocity, just before the book reaches the floor. Find the direction of book's velocity, just before the book reaches the floor.
How much energy is lost through the walls of the hot water heater in one week? (Assume thinner surface of the heater is 90 C and the outer surface is 27 C.)

How far from a point on the floor directly below the edge. Why is it a good idea to have your hand extended forward when you are getting ready to catch the fast moving baseball with your bare hand.
A parallel-plate capacitor has an area of 2.0cm^2, and the plates are separated by 2mm.
A 190 kg block is pulled at a constant speed of 4.4 m/s across a horizontal floor by an applied force of 138 N directed 37° above the horizontal. Illustrate what is the rate at which the force does work on the block?
A roller coaster is towed up an incline at a steady speed of 0.51m/s by a chain parallel to the surface of the incline. The slope is 2.85 % that means that the elevation increases by 2.85 m for every 100m of horizontal distance.
