A ball with a density of 0.940 g/cm^3 and a volume of 1.4 ´ 10^4cm^3 is placed in a fluid with a density of 0.870 g/cm^3. Does the ball sink or float? If the ball floats, calculate the volume of the displaced fluid. If the ball sinks, calculate the magnitude of the apparent weight of the ball.

Abaseball picther can throw a ball at about 90 miles per hour, v = 40 m/s, on solid rock ground. we now put him into space. when he throws the ball, which weighs mb = 0.15 kg moves away from himat the same speed. how long does it take the ball thrown in space to travel the 30 meters to the batter? he weighs mp = 100kg

However, had it been a real sound, the sound's pitch would have been increased by the doppler effect, since the falcon was moving the source of the sound. perpendicular to away from towards at the same speed as

The energy of a photon was found to be 3.38 × 10–19 j. planck’s constant is 6.63 × 10–34 j • s. which color of light corresponds to this photon?
