Upper A 4-kg mass is attached to a spring hanging from the ceiling, thereby causing the spring to stretch 3.92 m upon coming to rest at equilibrium. At time t equals0, an external force of Upper F (t )equals 4 cosine t N is applied to the system. The damping constant for the system is 8 N-sec/m.

Determine the steady-state solution for the system.

Which of the following represents an upside-down image? o a. +doo b. -doo c. +mo d.-m

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c

Adisk with a radius of r is oriented with its normal unit vector at an angle q with respect to a uniform electric field. which of the following would result in an increase in the electric flux through the disk? check all that apply? a. increasing the area of the disk b. decreasing the given orientation angle of the disk c. decreasing the strength of the electric field d. increasing the given orientation angle of the disk, but not exceeding an angle of 90
