A 120-V motor has mechanical power output of 2.50 hp. It is 90.0% efficient in converting power that it takes in by electrical transmission into mechanical power.
(a) Find the current in the motor.
(b) Find the energy delivered to the motor by electrical transmis- sion in 3.00 h of operation.
(c) If the electric company charges $0.110/kWh, what does it cost to run the motor for 3.00 h?
Find the potential on the axis of a charged ring carrying some charge density (lamda) uniformly distributed around it
Coefficient of kinetic friction between tires and road
Two friends, Barbara and Neil, are out rollerblading. With respect to the ground, Barbara is skating due south at a speed of 2.7 m/s. Neil is in front of her.
Find out the depth of the kerosene
A sphere of radius R = 0.325 m and uniform charge density -151 nC/m3 lies at the center of a spherical, find the magnitude of the electric field at the following radial distances from the center of the charge distribution
A tungsten wire has a radius of 0.086 mm and is heated from 20.0 to 1422 oC. The temperature coefficient of resistivity is ? = 4.5, How long is the wire
A spring (k =805N/m) is hanging from ceiling of an elevator, and a 5.0-kg object is attached to the lower end. By how much does the spring stretch (relative to its unstrained length) when the elevator is accelerating upward at a = 0.47m/s2.
Calculate the speed of an electron after it accelerates from rest through a potential difference of 160 .
The Space Shuttle travels at a speed of about 7.60 103 m/s. The blink of an astronaut's eye lasts about 110 ms. How many football fields (length = 91.4 m) does the Shuttle cover in the blink of an eye?
A steel cable has a cross-sectional area 3.44 × 10-3 m2 and is kept under a tension of 1.53 × 104 N. The density of steel is 7860 kg/m3. Note that this value is not the linear density of the cable. At what speed does a transverse wave move along t..
A small piece of dust of mass m = 1.0 µg travels through an electric air cleaner in which the electric field is 500 N/C, What is the charge on the dust particle
Your projectile launching system is partially jammed. It can only launch objects with an initial vertical velocity of 42.0 m/s, though the horizontal component of the velocity can vary.
