A heater coil connected to a 240 Vrms ac line has a resistance of 34 Ohms.
a) what is the average power used?
b) What are the max and min values of the instantaneous power?
A cyclist rides a bike at 12.0 miles/hour. The diameter of the wheels is 70.0cm. (a) Through how many turns do the wheels spin for the 12.0mile trip, what is the bikes angular acceleration
Blocks A and B are connected across a frictionless pulley by a cord of negligible weight. If block B lies on a horizontal, frictionless surface and block A hangs vertically, what can be said about the acceelration of block B?
A 1.82-cm high object is placed 22.0 cm in front of a concave mirror with a 3.55-cm focal length. What is the position of the image
The partial pressures of gas A and gas B, respectively, are 0.238 atm and 0.779 atm. If 0.220 mol a third gas is added with no change in volume or temperature, what will the total pressure become?
Far in space, where gravity is negligible, a 485kg rocket traveling at 95.0m/s fires its engines. It shows the thrust force as a function of time. The mass lost by the rocket during these 30 s is negligible.
Find out a formula for a electrical flux on a sphere for a point charge at the center of the sphere with a hole in the sphere.
An airplane must reach a speed of 172 mi/h to take off. If the runway is 470 m long, what is the minimum value of the acceleration that would allow the airplane to take off productively.
It collides with and sticks to the spring, which is compressed by 2.50 cm in bringing the block to a momentary halt. Assuming air resistance is negligible; from what height (in cm) above compressed spring was the block dropped.
Police determine skid marks 83 m long on the highway showing where the car made an emergency stop. Assume that the acceleration was -10 m/s2 (about the highest for dry pavement), how fast was the car going.
You throw a ball straight up in the air. The instant after leaving your hand, the balls speed is 30 meters per second. Ignoring the effects of air resistance, predict how fast the ball will be traveling 2 seconds later.
The work done by an engine equals one-half the energy it expels to a cooler at 0C. what is the temperature of the heater
On a workday the average decibel level of a busy street is 71 dB, with 100 cars passing a given point every minute. If the number of cars is reduced to 40 every minute on a weekend
