The lightbulb in the circuit shown in the figure(Figure 1) has a resistance of 14? and consumes 9.7W of power; the rod is 1.20m long and moves to the left with a constant speed. The strength of the magnetic field is 1.8T .
find current in the circuit. (I)
find speed of the rod (m/s)
Through a hard sneeze, your eyes might shut for 0.70s. If you are driving a car at 100 km/h during such a sneeze, how far does the car move for the duration of that time.
at rest, a light source emits 532 nm light. as it moves along a line connecting it and Earth, observers on Earth measure the wavelength to be 412 nm. What is the sources velocity and direction? Were it to move in opposite direction at the same spe..
A constant horizontal force a pushes a kg FedEx package across a frictionless floor on which an xy coordinate system has been drawn. package's x and y velocity components versus time t.
A lighthouse that rises 49 above the surface of water sits on a rocky cliff that extends 19 from its base. A sailor on the deck of a ship sights the top of the lighthouse at the angle of 30.0 above the horizontal.
In the vertical case the maximum tension in the string is 18.0% larger than the tension that exists when the circle is horizontal. Identify the speed of the stone.
If you drop an aspirin and it takes 0.18 sec to hit the table, how high above the table was the aspirin when it released?
An ocean liner leaves New York City and travels 18.0° north of east for 232 km. How far east and how far north has it gone? In other words, what are the magnitudes of components of the ship's displacement vector in the following directions.
The movement of the water because of the tides will give kinetic energy to the turbine blades, causing them to spin. In the calculations that follow ignore any frictional drag because of the seawater.
orville walks 318 m due east. He then continues walking along the straight line, but in a different direction, and stops 164 m northeast of his starting point. How far did he walk during the second portion of trip and in what direction.
A loudspeaker of mass 21.0 {rm kg} is suspended a distance of h = 2.40 {rm m} below the ceiling by two cables that make equal angles with the ceiling. Each cable has the length of l = 3.90 {rm m}.
