A 35-kg block is supported by the spring arrangement shown. The block is moved vertically downward from its equilibrium position and released. Knowing that the amplitude of the resulting motion is 45 mm, determine
(a) the period and frequency of the motion,
(b) the maximum velocity and maximum acceleration of the block.
Calculate the magnitude of the maximum orbital angular momentum Lmax for an electron in a hydrogen atom for states with a principal quantum number of 44
A mass lies on a inline plane with an angle of q with the horizontal by a string connected to the top of the plane. What minimum value of the coefficient of static friction
Point charges located at 3, 8, and 11 cm along the x - axis are represented in the figure (at 3cm +q, 8cm -2q, 11cm +q). What is the magnitude of the force on the charge
Calculate the transmittance T and the reflectance R, that is, the relative amounts of power transmitted through and reflected from the boundary. Verify that your answers are consistent with the law os conservation of energy.
An open plastic soda bottle with an opening diameter of 2.2cm is placed on a table. find the total magnetic flux through the plastic of the soda bottle
a tunnel leading straight through a hill makes tones at 135 hz and 165 hz especially loud due to standing waves.
The magnetic flux that passes through one turn of a 18-turn coil of wire changes to 2.62 from 9.44 Wb in a time of 0.0336s. What is the resistance of the wire
Superman throws a boulder of weight 1950N at an adversary on the surface of the earth, What horizontal force must Superman apply to the boulder to give it a horizontal acceleration of 14.6m/s2
A plane wall with surface temperature of 350C is attached with straight rectangular fins (k = 235 W/mK). The fins are exposed to an ambient air condition of 20C and the convection heat transfer coefficient is 154 W/m2K. Each fin has a length of 50 mm..
