Q. The rms voltage across a 5.02 Ω resistor is 34.7 V. Find the maximum instantaneous current through the resistor.
Q. A 22 kg radio is moving on a frictionless surface. Two forces F=50Ni and F=40Ni act in the same direction on the radio, pushing it in a straight line. Draw a free body diagram of the radio and the forces on it. Calculate the acceleration on the radio. Express your answering component and magnitude angle notation.
A 5.20 g pop up toy is compressed 1.50 cm and pops up to the height of 50 cm the spring constant is 270 Nm. What is the loss of energy.
Next you eliminate the 11 kg mass, place the rod horizontally, and strike one end with a hammer. How much time t would elapse before a microphone at the other end of the bar will detect a disturbance.
Assume your car was modified so you could travel through space. At a velocity of 65 mi/hr, and driving non-stop, how long would it take for you to get to.
A cyclist is traveling at an initial speed of 10.0m/s. She accelerated at a rate of 0.500m/s^2. What is her final speed after 9.
The sodium D line is a doublet consisting of two wavelengths, 588.995 and 589.592 nm. Calculate the angular separation between these two lines in the first-order spectrum for a grating with 4000 lines per centimeter. Repeat for the second order.
Intuitively, the man will not catch the bus unless he is running fast enough. In mathematical terms, there is a constraint on the man's speed so that the equation above gives a solution for that is a real positive number.
Find out the resulting values of the processional rate
An airplane is flying with the velocity of 85.0 m/s at an angle of 20.0 degrees above the horizontal. When the plane is a distance 107 m directly above the dog that is standing on level ground, a suitcase drops out of the luggage compartment. How far..
A 246 kg wooden raft floats on a lake. as a 85 kg man stands on the raft, it sinks 5.0 cm deeper into the water. When he steps off, the raft vibrates for a while.
Heat Q flows spontaneously from a reservoir at 445 K into a reservoir at 265 K. Because of the spontaneous flow, 2620 J of energy is rendered unavailable for work when a Carnot engine operates between the reservoir at 265 K and a reservoir at 248 K. ..
W hat is the downward acceleration of the blue spool
When in deep space, the block accelerates at 4.2 m/s^2 even as a 120 N force is applied to it. The coefficient of static friction for a particular plane and this block is 0.31. What angle can this plane make with horizontal before the object starts t..
