A charge of -3.55 nC and a charge of -5.65 nC are separated by a distance of 60.0 cm. Find the position at which a third charge of +7.20 nC can be placed so that the net electrostatic force on it is zero.

A baseball (m = 147 g) approaches a bat horizontally at a speed of 40.5 m/s (90.6 mi/h) and is hit straight back at a speed of 51.0 m/s (114 mi/h). If the ball is in contact with the bat for a time of 1.36 ms, what is the average force exerted on the ball by the bat? Neglect the weight of the...

Antarctica is roughly semicircular, with a radius of about r = 2100 km. The average thickness of its ice cover is about h = 3000 m. How many cubic centimeters of ice does Antarctica contain? (Ignore the curvature of Earth.)

for over having an engine tripod of the type shown is used to lift the engine from the car assembly, determine the max safe load W that can be supported by the tripod shown without exceeding the compressive force of 2.4kN in any of its legs.

a car has a mass of 1000 kg. determine the work done in moving the car at constant speed a distance of 250 m along a horizontal asphalt paved road

i want cd or exam paper for physic giancoil sixth edition physc 2102 chapter 13,14,16,17,,17,19,20,21 please i want with answer

I don't know how to work any of these problems and how to solve them. And, we must not round any answers. all answers must have every decimal that is in the calculator.

Earthquakes produce several types of shock waves. The most well-known are the P-waves (P for primary or pressure) and the S-waves (S for secondary or shear). In the earth's crust, the P-waves travel at around 6.5 { km/s} while the S-waves move at about 3.5 {km/s}. The actual speeds vary...
