Two positively charged particles q1 = 2C and q2 = 2C are separated by distance d = 1.0 m. Calculate the total electric potential energy of 3 particles when a charged particle, q3 = 2C, is placed at ¼ the distance between the two particles q1 and q2.
Two equally charged insulating balls each weigh 0.50 g and hang from a common point by identical threads 30 cm long, What is the magnitude of the charge on each ball
A cube of ice is taken from the freezer at -8.4^circ C and positioned in a 114 g aluminium calorimeter filled with 322g of water at room temperature of 20.0 C. The final situation is observed to be all water at 15.0C.
Illustrate what was the impact on Mosby's 2012 net income as a result of this fair value hedge of a firm commitment?
A 529 kg automobile slides across an icy street at a speed of 66.0 km/h and collides with the parked car which has a mass of 856 kg. The two cars lock up and slide together. What is the velocity of the two cars just after they collide.
A car takes 16 s to go from v = 0 to v = 50 m/s at approximately constant acceleration. If you wish to find the distance travelled using the equation d = 1/2 at2, what value should you use for a.
The nucleus in an iron atom has a radius of about 4.0 X 10-15 m and contains 26 protons, What is the magnitude of the gravitational force between those same two protons
A 2 g lead (cp = 128 J/kg•°C) bullet travelling at 325m/s is stopped by the large tree. If half the kinetic energy of the bullet is transformed into internal energy and remains with the bullet whereas the other half is transmitted to the tree, wha..
Discuss how big is a physical protocol data unit and determine the number of simultaneous transmissions for many network architectures.
An electron has an initial velocity of 3.50 106 m/s in the x direction. It enters a uniform electric field = (400 N/C) , which is in the y direction. (a) Find the acceleration of the electron.
