The four heating elements on an electric stove are wired inparallel so that any combination of them can be on at the sametime. When an element is on, it behaves as a6.80 Ω resistor. When all of the heatingelements are on, what is the equivalent resistance of the stove?
A toy of mass 0.155 is undergoing simple harmonic motion (SHM) on the end of a horizontal spring with force constant 295 . When the object is a distance 1.15×10?2 from its equilibrium position, it is observed to have a speed of 0.305.
The velocity vs time graph of an object is approximated by a triangle which starts at v=0 at t=0, rises to a maximum of v=6 m/s at t=6 sec, then returns to zero at t=10 sec. How far did the object travel?
In Figure (a), two circular loops with different currents but the same radius of 10. cm, are centered on a y axis. They are initially separated by distance L = 7.5 cm, with loop 2 positioned at the origin of the axis
What is the acceleration of the baseball and what is the acceleration in g's - what was the rocks velocity when it hit the water?
A runner, jogging along a straight line path, starts at a position 260 m east of a milestone marker and heads west. After a short time interval he is 120 m west of the mile marker.
A single force acts on a 8.0 kg particle-like object in such a way that the position of the object as a function of time is given by x = 3.0t - 4.0t 2 + 1.0t 3, Find the work done on the object by the force
find out the speed of the test charge. How many electrons should be removed from A and put onto B to make the electrostatic force that acts on each object an attractive force whose magnitude is 23.6 N.
