Two new particles, which have identical positive charge q3, are placed the same 8.09 centimeters apart, and the force between them is measured to be the same as that between the original particles.
Assume that none of the alpha particles bounced back from the sheet, meaning that the alpha particles either were captured by the shielding or penetrated completely through the shielding. What perce
For a particular collision you detect the emitted products and find 17 protons, 4 antiprotons, 8 positrons, and 28 neutral particles. How many electrons are also emitted?
By what distance has the proton been deflected sideways when it reaches the far edge of the capacitor? Assume the field is uniform inside the capacitor and zero outside the capacitor.
A uniform electric field of magnitude 256 V/m is directed in the negative y direction. A +12.9 uC charge moves from the origin to the point (x, y) = (20.0cm, 45.6 cm). What was the change in the pot
An electron starts from rest 2.84 cm from the center of a uniformly charged sphere of radius 2.19 cm. If the sphere carries a total charge of 1.18E-9 C, how fast will the electron be moving when it
To maintain an inside temperature of 21.9°C if the outside temperature is 0.0°C? Disregard radiation and the energy lost by heat through the ground.
Question: A single isolated conductor can store charge. We can define its capacitance as the ratio of the charge to the potential at the surface. (Alternatively, one can think of a second conductor
Three charges are placed on the y axis. One charge of -2.4 micro-Coulombs is placed at y = 0, another charge of +1.7 micro-Coulombs is placed at y = -0.2 meters, and another unknown charge is placed
How much charge, in micro-coulombs, was exchanged? Use the absolute value of the charge exchanged so the answer is positive.
What is the angle the total electric force on the charge at x = +16 cm, y = 0 cm makes when measured from the positive x direction, counter-clockwise? Answer in degrees.
In 2010, the men's record for the 26.22 miles Boston Marathon was 2 hours 5 minutes and 52 seconds. What was the average speed of the runner in units of m/s?
Suppose a free electron is located 0.551 nm above the midpoint of the sodium chloride molecule. What is the magnitude of the electrostatic force the molecule exerts on it?
There are four charges, each with a magnitude of 1.88 µC. Two are positive and two are negative. The charges are fixed to the corners of a 0.44-m square, one to a corner, in such a way that t
Calculate the fast neutron flux needed to produce the same injury as 0.50 mSv/hr of thermal neutrons, and then, as 6,000 thermal neutrons per sq. cm per sec. Please show your work.
Two particles with electric charges Q and 3Q are separated by a distance of 2.4 m. (a) If Q = 3.7 C, what is the electric force between the two particles?
An aluminum-alloy rod has a length of 10.008 cm at 16.400°C and a length of 10.020 cm at the boiling point of water. (a) What is the length of the rod at the freezing point of water? (Answer to th
A survey meter has been accurately calibrated in mR/hr. The measured value is then used directly by a technologist in Texas to determine the length of time a radiation worker can remain near a larg
Calculate the absorbed dose in Gy to the skin of a person which receives 1500 ergs/gm of beta radiation from a cloud of radioactive krypton-85 gas. Recalculate the dose if the same energy were depo
To measure the height of a tree, you throw a rock directly upward, with a speed just fast enough that the rock brushes against the uppermost leaves and then falls back to the ground. If the rock is
Given three measured elongation strains, e1 = 0.000410 i, e2 = -0.000290(-0.5i+0.866j), and e3 = 0.000610 (0.5i + 0.866j). find the state of strain at this location, find the principle strains, fin
