A student is doing Lab 3: Motion in One Dimension. The student places 50 g on the cart and 50 g one the hanger, then measures the acceleration. The student then moves 10 g from the cart to the hanger. What happens to the acceleration? Show any calculations and explain your reasoning.
Estimates is the acceleration of the object.
A horizontal magnetic field of 1.0x10^(-4) T is at an angle of 30 degrees to the direction of the current in a straight wire 75 cm long, what is the magnitude of the force on the wires
A person looks horizontally at the edge of a swimming pool. If its length is 5.00m, and the pool is filled to the surface, to what depth (in m) could observer see? For water is 1.33).
A submarine is 325 m horizontally out from the shore and 115 m beneath the surface of water. A laser beam is sent from the submarine so that it strikes the shore.
A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 8.60 m/s at an angle of 25.0° below the horizontal. Find the height from which the ball was thrown
An inductor (L = 400 mH), a capacitor (C = 4.43 F), and a resistor (R = 500 ?) are connected in series. A 50.0-Hz AC source produces a peak current of 250 mA in the circuit. (a) Calculate the required peak voltage Vmax. (b) Determine the phase ang..
An electron is traveling through a region of space in which the electric field is along the +x direction and has a magnitude of 2313 N/C. What is the acceleration of the electron? magnitude m/s2 direction
Two adjacent sources each emit a frequency of 800Hz in air where the velocity of sound is 340 m/s. How much farther back would source 1 have to be moved as a result an observer in front of the sources would hear no sound.
