How do I calculate the resonance frequency for a physics lab given that the L=.084Hz, C=.0015*10^-6F and that the total resistance in the circuit is 2434ohms?
The velocity of a particle moving in the xy plane is given by = (5.5t - 4.5t2)i + 8.3j , with in meters per second and t (> 0) in seconds. At t = 1.8 s and in unit-vector notation what positive t
The first person is initially moving forward with a speed of 2.50 m/s, and the second person is initially at rest. What are the velocities of the two people after the snowball is exchanged? Disregar
A chair of weight 145.0 N lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of F = 40.0 N directed at an angle of 43.0 degrees below the horizontal and
A loudspeaker of mass 25.0 {rm kg} is suspended a distance of h = 1.60 {rm m} below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of l = 3.50 {rm m}.
A rifle is aimed horizontally at a target 47 {rm m} away. The bullet hits the target 2.0 {rm cm} below the aim point. What was the bullet's flight time?
What is the approximate fraction of the hydrogen atoms that are in the second excited state (and therefore could emit a photon)?
An object at rest on a flat, horizontal surface explodes into two fragments. One fragment is 7 times as massive as the other. The heavier fragment slides 8.70 m before stopping. How far does the li
A typical person radiates about 62 W of power at room temperature. How long does is take for a person to radiate away the energy acquired by consuming a 230 Calorie doughnut?
A 18.6g of Styrofoam carries a net charge of -0.686 uC and floats above the center of a large horizontal sheet of plastic that has a uniform charge density on its surface. What is the charge per un
A race car has a mass of 703 kg. It starts from rest and travels 40.0 m in 3.0 s. The car is uniformly accelerated during the entire time. What net force is exerted on it?
When an external resistor of resistance R1 = 16 Ω is connected to the terminals of a battery. Calculate: the internal resistance of the battery.
A small steel ball bearing with a mass of 23.0 g is on a short compressed spring. When aimed vertically and suddenly released, the spring sends the bearing to a height of 1.43 m. Calculate the horiz
A 0.25 kg skeet (clay target) is fired at an angle of 28 degrees to the horizon with a speed of 25 m/s. When it reaches the maximum height, h, it is hit from below by a 15m g pellet traveling vertic
A 30.0 mu F capacitor initially charged to 30.0 mu C is discharged through a 2.10 kOmega resistor. How long does it take to reduce the capacitor's charge to 6.00 mu C?
