Asinusoidal traveling wave is generated on a string by an oscillating source that completes 116 cycles per minute. what is the wavelength of the wave if individual crests are observed to travel 11.0 m in 1.50 min?

Ahot-air balloon takes off from the ground traveling vertically with a constant upward acceleration of magnitude g/4. after time interval δt, a crew member releases a ballast sandbag from the basket attached to the balloon. how many seconds does it take the sandbag to reach the ground? (express your answer in terms of δt)

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.

Which of the following is not an appropriate unit for acceleration? (kg/12 mihr? m/min/sec cm/30c?
