A hot-air balloon has just lifted off and is rising at the constant rate of 2.2 m/s . Suddenly one of the passengers realizes she has left her camera on the ground.
A helicopter is ascending vertically with a speed of 4.50 m/s. At a height of 195 m above the Earth, a package is dropped from a window. How much time does it take for the package to reach the ground.
A particular guitar string is supposed to vibrate at 191- Hz, but it is measured to actually vibrate at 210- Hz. By what percent should the tension in string be changed to get the frequency to the correct value.
A charge q = -6.0 µC is moved 0.25 m horizontally to point P in a region where an electric field is 250 V/m directed vertically, as shown. What is the change in the electric potential energy of the charge?
A cork on the surface of a pond bobs up and down two times per second on ripples having a wavelength of8.20cm. If the cork is10.5m from shore, how long does it take a ripple passing the cork to reach the shore?
They want to dock, which means they have to arrive at the same position at the same time with zero velocity. (a) What should the initial velocity of the second spacecraft be? (b) Illustrate what should be its constant acceleration?
The volume control on a surround-sound amplifier is adjusted so the sound intensity level at the listening position increases from 21 to 59 dB. What is the ratio of the final sound intensity to the original sound intensity?
Two sound sources driven in phase by the equal amplifier are d = 4 m apart on the y axis. At a point a very large distance from the y axis, constructive interference is first heard at an angle θ1 = 0.140 rad with the x axis.
Draw a picture of a moving source and the waves surrounding it according to what you observed in this experiment. How does the spacing of the wavefronts in front of the source compare to those behind it?
