The particles in the nucleus of an atom are approximately 1.00×10?15 apart, while the electrons in an atom are about 1.00×10?10 from the nucleus.
Part A: Calculate the electrical repulsion between two protons in a nucleus if they are 1.45×10?15 apart.
Part B: How many pounds would the force be?
Part C: Calculate the electrical attraction that a proton in a nucleus exerts on an orbiting electron if the two particles are 1.28×10?10 apart.
You stand on the shore of a small river that measure 10 meters across. You take your cat and throw it into the middle of the stream. How long did it take the cat to reach you
An aluminum rod is clamped one quarter of the way along its length and set into longitudinal vibration by a variable-frequency driving source. obtain the length of the rod
The sun radiates energy at the rate 3.8*10^26W. The source of this energy is fusion, a nuclear reaction in which mass is transformed into energy. Estimate the lifetime of the sun
The filament of a light bulb has a temperature of 2.64 x 103 °C and radiates 60.0 W of power. The emissivity of the filament is 0.388. Find the surface area of the filament
A copper cylinder with a temperature of 277 K is found to emit 179 J of energy each second. what is its surface area
How much work must be done on the electron to move it to negative plate if it is initially positioned 2.86 mm from the positive plate.
10.0g of aluminum at 200?C and 22.0g of copper are dropped into 42.0cm3 of ethyl alcohol at 15?C. What was the initial temperature of the copper
A length of aluminum wire has a resistance of 16.0 ? at 28.0°C. When the wire is warmed in an oven and reaches thermal equilibrium, find the temperature of the oven
A point charge of ?3.3 ?C is located in a uniform electric field of 34 N/C. You move the charge, find the resulting change in the electric potential energy of the system
The potential at the center of a uniformly charged ring is 44kV, and 15.0 cm along the ring axis potential is 30kV. Find the ring's radius and its total charge.
Due to concerns about the salt water content in the estuary, the discharge in the channel needs to be varied to mimic tidal effects. This means that for 12 hours a day, the channel needs to carry a flow of 8m3.s1, and for the other 12 hours the fl..
A force that varies linearly with time according to a relation F = 4t N is applied to an object travelling with a speed of 16-m/s. If the force decelerates the object to a complete stop in 5s, determine the object's mass. Imagine the force is at f..
