(c) Compute its kinetic energy.
Avoiding air resistance, what is the magnitude of the total velocity of the package at the moment it is thrown as seen by an observer on the ground? Answer in units of m/s.
Two small identical conducting spheres are placed with their centers 25 cm apart. One is given a charge of 20.0 nC and the other given a charge of -36.0 nC. What is the electrical force of each sphere on the other?
Rubber stopper attached to one end of the string and 100 g mass attached to the other end. A student gets the rubber stopper going in a horizontal circle above her head.
Assuming that air resistance exerts a 95 N force on the person during the fall, identify the person's velocity just before hitting the net.
what is the cost of the electric energy equivalent to the energy in a Big Mac? (the cost of a Big Mac is $3.57)
The telescope at a small observatory has objective and eyepiece focal lengths respectively of 20.0 m and 12 cm. determine length of the barrel of the telescope
A magnetic field has a magnitude of 1.20*10-3 T, and an electric field has a magnitude of5.60*103 N/C. Both fields point in the samedirection. A positive 1.8-µC charge moves at a speed of2.80*106 m/s in a direction that isperpendicular to both fields..
A photon by wavelength λ is absorbed by an electron confined to a box. As a result, the electron moves from state n = 1 to n = 7. Discover the length of the box. Express your result using h, m, c, and lambda to represent Planck's constant, the electr..
Quentin is lifting a 10 kg dumbbell by pulling upward on it with a 108.1 N force. What is the acceleration of the dumbbell
Gravitational Field. The gravitation field produced by an object is defined as the gravitational force that the object exerts on a small test particle of mass m divided by m.
An archer puts a 0.54 kg arrow to the bowstring. An average force of 202 N is exerted to draw the string back 1.3 m. suppose that air resistance is negligible.
