Q1. A force vector points at an angle of 50.6° above the +x axis. It has a y component of +280 newtons. Calculate the magnitude of the force vector.
Q2. Two point charges have a total charge of 280 microC . When placed 1.94m apart, the force each exerts on the other is 27.2 N and is repulsive. What is the charge on each?
Q3. A metal sphere has a charge of +9.0C. What is the net charge after 9.8 x 10^13 electrons have been placed on it?
What is Johns resultant displacement
Which state is best illustrates kinetic friction
If you place a 0.0001-C charge halfway between the terminals of a common 9-v battery, 5 mm apart, what force will that charge experience.
If a parallel mirror He-Ne laser had a homogeneous line shape with v=1.5GHz, and small signal peak coefficient of .001/cm length=100cm and reflectance's 100 percent and 97 percent, how many longitudinal modes would initially contribute to the laser o..
A submarine dives 90.0 m at an angle of 8.0° below the horizontal. What are the horizontal and vertical components of submarine's displacement? (Imagine that upward and the direction of the submarine's horizontal motion is positive.)
Find the final displacement from the starting point. How much greater was the distance she walked than her displacement.
After being accelerated to a speed of 1.26×105 m/s, the particle enters a uniform magnetic field of strength 2.00 T and travels in a circle of radius 35.0 cm (determined by observing where it hits the screen). The results of this experiment allow one..
A spring stiffness 900 N/m and relaxed length 1m stands vertically on a table. You hold a block of mass 1 kg barely touching the top of the spring. Assume you let the mass down onto the spring certain distance very slowly and view the mass is not mov..

Where does package hit the ground relative to the point
A vertical scale on a spring balance reads from 0 to 160 N. The scale has a length of 12.5cm from the 0 to 160 N reading. A fish hanging from the bottom of spring oscillates vertically at the frequency of 2.30 Hz. ignoring the mass of the spring, wha..
