Kinetic and Spring Potential Energy Problem: A block (m = 5 kg) is pushed against a spring that is compressed a distance x = 10 cm. The block is then released and travels up a frictionless, inclined surface. Find the maximum height h of the block if the spring constant k = 100 N/m. FIRST, solve for the height h algebraically, and THEN substitute numerical values. Show ALL work and units.
A Capacitor and resistor are connected in series forming an RC circuit. If the resistance in the circuit is set at 700 OHMS, What amount of the charge is on the capacitor
a large metal sheet of thickness l is placed between and parallel to the plates of the parallel-plate capacitor of the
The lowest string on a certain acoustic guitar is 0.582m in length. Under a tension of 65.3N, the string has a resonant frequency of 285.03 Hz. What is the linear density of the string in kg/m?
A pulsar is a rapidly rotating neutron star that emits a radio beam the way a lighthouse emits a light beam. We receive a radio pulse for each rotation of the star. The period T of rotation is found by measuring the time between pulses. The pulsar..
A "biconvex" lens is one in which both surfaces of the lens bulge outwards. What is the focal length f of this lens in air
A liquid of density 1.39 × 103 kg/m3 flows steadily during a pipe of varying diameter and height. At location 1 along the pipe the flow speed is 9.35 m/s and the pipe diameter is 12.9 cm.
A transverse sinusoidal wave on a string has a period T = 36.0 ms and travels in the negative x direction with a speed of 30.0 m/s. At t = 0, What is the maximum transverse speed of the string
A long solenoid (cross-sectional area = 0.99 x 10-6m2, number of turns per unit length = 2429 turns/m) isbent into a circular shape so it looks like a doughnut.
Two cylindrical bars, each with diameter of 2.30 cm, are welded together end to end. One of the original bars is copper and is 0.350 m long
Why is the thermal energy not shared instantaneously with the rest of the block to warm it as a whole?
An air-track glider is attached to a spring. The glider is pulled to the right and released from rest at t =0s . It then oscillates with a period of 1.50 sand a maximum speed of 36.0 cm/s. What is the amplitude of the oscillation? What is the glider'..
Small telescopes are often advertised as "200 power" or "magnifies 200 times." As someone knowledgeable about astronomical telescopes, how would you progress such advertisements.
