Match the process by the fundamental interaction responsible for this process.
An apple is held off the ground by the surface of a table:
1. The weak interaction.
2. The normal interaction.
3. The strong interaction.
4. The air resistance/friction.
5. The gravitational interaction.
6. The electromagnetic interaction.
6. How many more minutes would it take light from the sun to reach Earth if the space among them were filled with water rather than a vacuum? The sun is 1.5 x 108 km from Earth.
A block of mass 2.00kg starts at rest at the top of a ramp that is inclined delta= 40.0 degrees with the horizontal. The block slides down the ramp a distance of 3.60 meters where it contacts a relaxed spring with K=300N/m. If the coefficient of k..

A block is hung by a string from the inside roof of a van. When the van goes straight ahead at a speed of 25 m/s, Compute what is the angle that the string makes
Beams of high-speed protons can be produced in "guns" using electric fields to accelerate the protons. Find what acceleration would a proton experience if the gun's electric field were 1.70 x 104 N/C
A hydraulic is designed with a line that is 62 ft long. If the applied pressure at one end of the line is 6 Pa, what is the applied pressure at the other end?
A ray of light in air makes an angle of incidence of 30.2 as it enters an unknown liquid. the refracted ray in the fluid meassured to be 22.5. compute the index of refraction of the unknown liquid
A ceiling fan consists of a small cylindrical disk with 5 thin rods coming from the center. The disk has mass md = 3.3 kg and radius R = 0.22 m. The rods each have mass mr = 1.2 kg and length L = 0.76 m.3) What is the moment of inertia of the whole c..
