20 of anything is larger than 5 of the same thing.
365 Hz or 375 Hz.
wave velocity = frequency in Hz x wavelength in meterSo frequency = 5 Hz and wavelength = distance between successive peaks = 20 cm = 20/100 mHence wave velocity = 5 * 20/100 = 1 m/s
The wave's velocity is 16 ft/s in the path of motion. (20*8)/10 0.333 Hz
1/5 Hz
400 Hz means 400 cycles per second, so each wave passes a point 400 times in one second
5 million nanometers is 5 mm so it is 5 times larger than one millimeter.
1.5 million ÷ 20% = 1.5 million × 100/20 = 1.5 million × 5 = 7.5 million
20 million × 5 billion = 100,000 trillion = 100 quadrillion on the short scale. 20 million × 5 billion = 100 trillion on the long scale.
1 million
5 million.
no..... wow.
The energy of a photon is given by the equation: E = h * f where E is the energy of the photon, h is Planck's constant, and f is the frequency of the photon. Plugging in the given frequency of 5 × 10^20 Hz, and using the value of Planck's constant h = 6.626 x 10^-34 joule seconds, we get: E = (6.626 x 10^-34 J s) * (5 x 10^20 Hz) = 3.313 x 10^-13 joules Therefore, the energy of a photon with a frequency of 5 × 10^20 Hz is approximately 3.313 x 10^-13 joules.
Answer = 2 million dollars
no it comes out in 20 million years
Probably something below 20 Hz. They are done with rotating motors with unbalanced shafts. Here is a page that shows lots of products.http://www.precisionmicrodrives.com/vibration_motors.php?_kk=cell%20phone%20vibrator%20motor&_kt=c8a02ca2-cd5f-4ac0-918f-9e11e3edc018&gclid=CNv2td_zuJ4CFQ8eDQodfUIwmAMy guess is the shaft spins on the order of 5 or 20 rev/sec - giving a fundamental frequency of 5 to 20 Hz. Maybe 10 Hz...
5 percent of 20 million dollars is 1 million dollars
5% of 20 million= 5% * 20000000= 0.05 * 20000000= your answer: 1,000,000 or 1 million
