An inductor is connected to the terminals of a battery that has an emf of 12.0V and negligible internal resistance. The current is 4.86mA at 0.725 ms after the connections is completed. After a long time the current is 6.45 mA. What is
At the end of the firing period, the craft has velocity components of vx = 3565 m/s and vy = 4556 m/s. Find the magnitude and direction of the initial velocity. Express the direction as an angle with respect to the +x axis.
Our galaxy, the Milky Way, contains approximately 4.0*10^11 stars with an average mass of 2.0*10^30kg each. How far away is the Milky Way from our nearest neighbor, the Andromeda Galaxy, if Andromeda contains roughly the same number of stars and a
Assume 18 g of a substance marketed as "Pure Energy" is annihilated by 18 g of a second substance "Anti-Pure Energy." How long would the energy released power a city which uses 1.7 × 109 W of power?
Yusef pushes a chair of mass Yusef pushes a chair of mass = 55.0 across a carpeted floor with a force (the subscript 'p' here is lowercase and throughout the question) of magnitude = 168 directed at = 35.0 below the horizontal. The magnitude of th
The squadron commander has a mandate that the database update must be complete in less than one minute. If the topo database is 10 GB, and the link is SONET, what is the minimum standard rate required?
What effect does this have on the three other light bulbs? What effect is there on the battery that is powering the circuit?
A block of mass mblock = 2 kg rests on a cart of mass mcart = 3.6 kg, which moves without friction on a horizontal surface. The coefficient of static friction between the block and the cart is µ = 0.71. The cart is accelerating to the right.
Calculate the the numerical value for the acceleration (Assume g = 9.81 m/s2).
A 365 kg mass is supported on a wire attached to a 15 m long steel bar that is pivoted at a vertical wall and supported by a cable. Find the force exerted by the wall on the steel bar.
