Abaseball of mass m1 = 0.37 kg is thrown at another ball hanging from the ceiling by a length of string l = 1.15 m. the second ball m2 = 0.71 kg is initially at rest while the baseball has an initial horizontal velocity of v1 = 2.5 m/s. after the collision the first baseball falls straight down (no horizontal velocity.)

randomized variables
m1 = 0.37 kg
m2 = 0.71 kg
l = 1.15 m
v1 = 2.5 m/s

In the image, the arrow is pointing to a celestial object. which attribute disqualifies the object from being a planet?

Wo audio speakers are placed on a vertical rail. speaker a is placed at head-level while speaker b is place at some variable height, \delta yδy, above speaker a. both speakers receive simultaneous input from a sine-wave generator so the speakers each produce a pure sinusoidal sound wave with a wavelength of 0.531 meters. calculate the lowest height that speaker b can be placed above speaker a to produce a minimum of sound heard by person standing \delta x = 7.86δx=7.86 meters directly in front of speaker a.

The passage that directs air to the lungs is called a. diaphragm. b. larynx. c. bronchi. d. pharynx.
