Two tiny, spherical water drops, with identical charges of -7.20 x 10-17 C, have a center-to-center separation of 1.4 centimeter.
(a) Find the magnitude of the electrostatic force acting between them?
N
(b) Find how many excess electrons are on each drop, giving it its charge imbalance?
electrons
A block of aluminum weight 140.0 g is cooled from 98.4 degrees celcius to 62.2 degrees celcius with the release of 1080 J of heat. From this data calculate the specific heat of aluminum
Why is it unwise to suddenly apply the brakes of a car on a wet or icy pavement? Everyday examples where areduction in the force of friction would be undesirable?
A 8.22 nC charge is located 1.82 m from a 4.38 nC point charge. (a) Find the magnitude of the electrostatic force that one charge exerts on the other.
A solenoid is to be constructed that will have a resistance of 5.00 ohms and produce a magnetic field of 0.0400 T at its center when it carries a current of 4.00 A. The solenoid will be made of wire that is 0.500 mm in diameter and have a radius that..
Suppose there are 3 equal resistors, how many arrangements, using all 3 resistors in each, could you set up? each arrangement should have a different total equivalent resistance.
Find the charge-to-mass ratio of an unknown point charge that is repelled strongly enough from a single electron to be suspended motionless against its own weight
Assume that the sun runs out of nuclear fuel & suddently collapses to form a white dwarf star, with a diameter equal to that of the Earth. Estimate the new rotation period of the Sun.
