A bowling ball (mass = 7.2 kg, radius = 0.15 m) and a billiard ball (mass = 0.32 kg, radius = 0.028 m) may each be treated as uniform spheres. What is the magnitude of the maximum gravitational force that each can exert on the other?
Use 9.81 for the magnitude of the acceleration due to gravity.
IF Earth's orbit were suddenly to become much more eccentric. keeping orbital semimajor axis as is, fixed at 1 AU, but let's imagine shifting both the Earth's perihelion and aphelion points by 0.9 AU, so that at perihelion we were only 0.1 AU from th..
An electron is accelerated from rest by the potential difference of 461 V. It then enters a uniform magnetic field of magnitude 184 mT with its velocity perpendicular to the field. Calculate (a) speed of the electron and (b) radius of its path in ..
A 1070-N uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end. A 1960-N crate hangs from the far end of the beam.
Two identical conducting spheres, fixed in place, attract each other with an electrostatic force of -0.6020 N when separated by 50 cm, center-to-center.
A 7 g bullet collides horizonally with a 43 g block resting on a frictionless horizontal surface as shown in the accompany diagram. The bullet remain embedded in the block and subsequently causes the block to slide down a frictionless slope onto a..
Oppositely charged parallel plates are separated by 4.52 mm. A potential difference of 600 V exists between the plates. (a) What is the magnitude of the electric field between the plates?
Select True or False for the following statements about conductors in electrostatic equilibrium. The electric field inside the conducting material is always zero.
A 16 kg wood ball hangs from a 2 m-long wire. The maximum tension the wire can withstand without breaking is 435 N. A 1.2 kg projectile traveling horizontally hits and embeds itself in the wood ball. What is the largest speed the projectile can ha..
find the period of this oscillation.
(a) Find the components of the net electric field at the origin. Ex = , Ey = (b) Find the magnitude and direction of the net electric field at the origin. |E| = at direction (from +x axis).
An archer puts a 0.33 kg arrow to the bowstring. An average force of 183 N is exerted to draw the string back 1.3 m. suppose that air resistance is negligible.
