A capacitor that is initially uncharged is connected in series with a resistor and a 400.4V emf source with negligible internal resistance. Just after the circuit is completed, the current through the resistor is 0.810mA and the time constant for the circuit is 6.10s .
What is the resistance of the resistor?
What is the capacitance of the capacitor?
A manager of a restaurant pushes horizontally with a force of magnitude 150 N on a box of melons. The box moves across the floor with a constant acceleration in the same direction as the applied force.
A parallel plate capacitor has plates of area 2.0x10^-3 m^2 and a plate separation of 1.0x10^-4 m. Determine the capacitance of this system if air fills the volume between the plates.
You want to estimate the height of the Empire State Building. You start at its base and walk 15 m away. Then you approximate the angle from the ground at that point to the top to be 88 degrees. How tall do you estimate the Empire State Building to..
what is the new force between the objects. if Andromeda contains roughly the same number of stars and attracts the Milky Way with a gravitational force of 2.4*10^30N.
Express your answers using two significant figures. Enter the x and y coordinates of the charge separated by a comma.
A 1.63 kg block of ice is sliding by you on a very slippery floor at m/s. As it goes by, you give it a kick perpendicular to its path. Your foot is in contact with ice block for 0.005 seconds. The block eventually slides at the angle of 24 degre..
Four identical particles each have charge q and mass m. They are free from rest at the vertices of a square of side L. How fast is each charge moving when their distance from center of the square doubles.
A baseball outfielder throws a 0.150 kg baseball at a speed of 45.0 m/s and an initial angle of 28.0°. Illustrate what is the kinetic energy of the baseball at the highest point of its trajectory?
Rhea, one of Saturn's moons, has a radius of 765 km and an acceleration due to gravity of 0.278 m/s2 at its surface. Calculate its mass and average density.
What is the frequency of light that has the wavelength in water of 788 nm if the refractive index for this light is 1.33.
According to legend, to determine whether the king's crown was made of pure gold, Archimedes measured the crown's volume by find out how much water it displaced. The density of gold is 19.3g/cm^3. If the crown's mass was 6.00 * 10^2g, what volume ..
A Ball Rolling Uphill. A bowling ball rolls without slipping up a ramp that slopes upward at an angle beta (B) to the horizontal. Treat the ball as a uniform, solid sphere, ignore the finger holes.
