A heavier mass m1 and a lighter mass m2 are 20.0 cm apart and experience a gravitational force of attraction that is 9.00 10-9 N in magnitude. The two masses have a combined value of 5.75 kg. Determine the value of each individual mass.
A small object of mass 4.06 g and charge -16.5 µC is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground
Two 14.0cm -diameter electrodes 0.50cm apart form a parallel-plate capacitor, What is the potential difference between the electrodes after insulating handles are used to pull the electrodes away from each other until they are 1.9cm apart
The mass of Venus is 0.8140 times that of earth, and its radius is 0.950 times that of earth. Calculate the acceleration of gravity at the surface of Venus
To explain why he seems to hang in the air, compute the ratio of the time he is above ymax/2 moving up to the time it takes him to go from the floor to that height. You may ignore air resistance.
A projectile is fired from the surface of the Earth with a speed 200 meters per second at an angle of 30 degrees above the horizontal. what is the maximum height reached by the projectile
Two loudspeakers on a concert stage are vibrating in phase. A listener is 57m from the left speaker and 30m from the right one. The listener can respond to all frequencies from 20 to 20 000 Hz.
