Two protons are released from rest, one from location 1 and another from location 2. When these two protons reach location 3, the first proton has a speed that is 3 times the speed of the second proton. If the electric potentials at locations 1 and 2 are 231 V and 115 V, respectively, what is the electric potential at location 3?
The atmospheric pressure at sea level is about 1.0 multiplied by 105 Pa. What is the force at sea level that air exerts on the top of the typical office desk, 159cm long and 86 cm wide?
Kelli weighs 405 N, and she is sitting on the playground swing that hangs 0.43 m above the ground. Her mom pulls the swing back and releases it when the seat is 1.00 m above the ground. suppose that air resistance is negligible.
A car traveling at a speed of vo = 60 m/s stops smoothly (that is, its deceleration is constant) over a distance of d = 167 m. What is its acceleration during the time it is stopping.
Two identical conducting spheres, fixed in place, attract each other with an electrostatic force of -0.6020 N when separated by 50 cm, center-to-center.
hysicists model a magnetic field by assigning to every point in space a vector that represents the strength and direction of the field at that point. Two magnetic fields that exist in the same region of space may be added as vectors at each point to ..
To see that it is easy to break a thighbone when falling in this fashion, find out the greatest distance through which his center of gravity can fall without his breaking a bone.
An infinitely long line of charge has a linear charge density of 8.00×10-12 C/m. A proton is at distance 16-cm from the line and is moving directly toward the line with speed 1200 m/s.
What is resultant force
what is the final equilibrium temperature of the system?
Find out d, the distance between the photogates, using the times and glider length. There is two ways to find this for the up and down directions.
A 140 g air-track glider is attached to a spring. The glider is pushed in 12.00 cm and released. A student with a stopwatch finds that 9 oscillations take 10.0 s.
