A beam of light with red and blue components of wavelengths 670 nm and 425 nm, respectively, strikes a slab of fused quartz at an incident angle of 30o. On refraction, the different components are
A model airplane is pushed by its engine with force F1: 16N due north while at the same time the wind pushes the airplane with force F2: 12.0 N at 50 degrees east of north" Calculate the magnitude o
A car starts driving at a speed of 5.833 m/s and speed up to a speed of 20 m/s. If the acceleration of the vehicle is 2.45 m/s/s how long did this take?
What is the net upward force on an airplane wing of area 20.7 m2 if the speed of air flow is 232 m/s across the top of the wing and 215 m/s across the bottom? (The density of air where the airplane
An aquarium contains a 5-cm layer of water (n = 1.33) floating on top of carbon tetrachloride (n = 1.461). If the angle of incidence into the water from the air is 30?, what is the angle of refract
A hornet circles around a pop can at constant speed once per second in a path with a 14-cm diameter. We can conclude that the hornet's wings must push on the air with force components that are:
At room temperature what is the strength of the electric field in a 6-gauge copper wire (diameter 4.12 mm) that is needed to cause a 1.73-A current to flow?
An excited atom can be release it's energy by emission of photons, such as X-rays or by emission of
Water is pumped into a storage tank from a well delivering 19.0 gallons of water in 26.0 seconds through a pipe of 1.00 in.2 cross-sectional area. What is the average velocity of the water in the p
Which physical parameter, more than any other, most probably controlled the early evolution of the planetary system and dictated the characteristics of the planets that eventually formed?
Two children push on opposite sides of a door during play. Both push horizontally and perpendicular to the surface of the door. One child pushes with a force of 19.5 N at a distance of 0.575 m from
The mass of Earth is 5.98 x 10^24 kg, and the mass of a single proton is 1.673 x 10^-27 kg. Assuming Earth is made entirely of protons, use an order-of-magnitude calculation to estimate the number
Today we talked about the Doppler Effect. How an observer can observe a higher or lower frequency than a source is actually emitting. This effect can happen if the observer and/or the source are mov
What is the rotational kinetic energy of the Earth? Use the moment of inertia you calculated in Part A rather than the actual moment of inertia given in Part B.
A speedboat starts from rest and accelerates at +2.41 m/s2 for 5.14 s. At the end of this time, the boat continues for an additional 6.24 s with an acceleration of +0.451 m/s2. Following this, the b
Explain what was observed with the horizontal motion of the man and the boat in terms of Newton's Laws of Motion.
A gold nucleus contains 197 nucleons packed tightly against each other. A single nucleon (proton or neutron) has a radius of about 1.310-15 m. Calculate the approximate radius of the gold nucleus.
A proton accelerates from rest through 1500 volts. the proton then enters a region of space where the magnetic field is 0.3 tesla (and this field is perpendicular to the velocity). calculate the rad
An electron moves at 2×106 m/s through a region in which there is a magnetic field of unspecified and magnitude 7.4×10-2T a)what is the largest possible magnitude of the acceleration of
A container has a vertical tube, whose inner radius is 12.00 mm, connected to it at its side. An unknown liquid reaches level A in the container and level B in the tube-level A being 5.0 cm higher t
A 0.25 harmonic oscillator has a total oscillation energy of 9.9 J. If the oscillation amplitude is 20.0 cm, what is the oscillation frequency?
Choose one part of the photo-electric experiment that cannot be explained by assuming that light is a wave. Why do we need the concept of light as a particle?
You are going to collect data to represent the variation of current as a function of the total resistance of the circuit. To do that, you will remove the bulbs one at a time until there is onlyone
