A 40 cm long tube has a 40 cm long insert that can be pulled in and out. As the insert is slowly pulled out, the sound from the tuning fork creates standing waves in the tube when the total length L is 42.2 cm, 56.7 cm, and 70.9 cm. What is the frequency of the tuning fork?
Rank the vector combinations on the basis of their angle, measured counter clockwise from the positive x axis. Vectors parallel to the positive x axis have the angle of 0. All angle measures fall between 0 and 360.
A tank having a volume of 0.100 m3 contains helium gas at 180 atm. How various balloons can the tank blow up if each filled balloon is a sphere 0.300 m in diameter at an absolute pressure of 1.50 atm.
Many people mistakenly believe that the astronauts that orbit Earth are "above gravity." Calculate g for space shuttle territory 150 km above Earth's surface. suppose Earth's mass is 6.0 1024 kg, and its radius is 6.38 106 m (6380 km). Your answer..

The magnitude of earth's magnetic field is 50.0 µT and makes an angle of 30° with the plane of the coil. Assume a patient takes 1.50 s to inhale, find the magnitude of average induced emf in the coil during that time.
When it passes point A, its velocity is 3.5 m/s directed as shown. The distance AP is 0.6 m and BP is 1.0 m. Find out the speed of the mass at points B and C.
By measuring the spectrum of wavelengths of light from our sun, we know that its surface temperature is 5760 K . By measuring the rate at which we receive its energy on earth, we know that it is radiating a total of 3.93×1026 J/s and behaves nearl..
