Compact fluorescent bulbs are much more efficient at producing light than are ordinary incandescent bulbs. They initially cost much more, but last far longer and use much less electricity.
At time a grinding wheel has an angular velocity of 22.0. It has a constant angular acceleration of 33.0 until a circuit breaker trips at time = 2.20. From then on, the wheel turns through an angle of 431 as it coasts to a stop at constant angular de..
A missile is fired from a launcher with an initial velocity of 250 m/s at a target located 500 m above the launcher, determine The possible firing angles required to hit the target
An electron of ? = 0.999 993 moves along the axis of an evacuated tube that has a length of 2.69 m as measured by a laboratory observer S at rest relative to the tube
An RLC circuit consists of a 218 resistor, a 45 ?F capacitor, and a 298 mH inductor, What is the phase angle between the current and the applied voltage
A 15 g rifle bullet traveling 250 m/s buries itself in a 3.0 kg pendulum hanging on a 2.9 m long string, which makes the pendulum swing upward in an arc. Clarify the horizontal component of the pendulum's displacement.
Illustrate what factor caused fewer purchases to be planned? Suggest business conditions that would cause this factor to both occur and impact the company in this way."
What are the first, second, and third frequencies audible from a 20cm long organ pipe when (1) only one end is open and when (2) both ends are open. The speed of sound through the air inside the organ pipe is 343 m/s. (Hint: if a harmonic does not..
A car initially travelling at 25.90 m/s undergoes a constant negative acceleration of magnitude 1.60 m/s2 after it brakes are applied. How many revolutions does each tire make before the car comes to a stop, assume the car does not skid and the ti..
A race car is moving with a velocity of 144 kilometers/hour. The driver applies the brakes, and the car comes to a halt in 12.0 seconds. What is the acceleration of the car after 12.0 seconds? A. -12 m/s^2 B. -3.3 m/s^2 C. 3.3 m/s^2 D. 10.3 m/s^2
State the maximum height in terms of a, t_1, and/or g. Note that in this problem, g is a positive number equal to the magnitude of the acceleration due to gravity.
A soccer ball with a mass of 448g bounces off the crossbar of a goal and is deflected upward at an angle of 56.2° with respect to horizontal. Immediately after deflection, the kinetic energy of the ball is 47.70 J. What are the vertical and horizo..
