What is the volume of a cube with an edge of 15 Cm?
Volume = edge3 = (15 x 15 x 15) = 3,375 cm3
What is the frequency in Hz and kHz if the period of oscillation is 7.5 ms?
Frequency = 1/period1/7.5 x 10-3 = 1331/3 Hz = 2/15 KHz
Can you make 15 volume developer using 30 volume and 40 volume?
NO. If you mix them in equal parts, that would give you 35 volume. To get 15 volume, mix equal parts of 10 and 20 volume.
A wave in a rope travels at 15 ms and its wavelength is 1.5 m calculate the wave's frequency?
C=?v 15 m/s= 1.5 m (v) v= 10 Hz
Which of the following frequencies can be heard by the human ear -- a. 0.1 Hz b. 10 Hz c. 1000 Hz or d. 100000 Hz?
1000 Hz. The others are outside the range of human hearing. You can feel 10 Hz but not hear it. C. 1,000 Hz
What is the wavelength of wave that has a frequency of 15 hz and speed of 2 meters per second?
Wavelength = speed/frequency = 2/15 Hz = roughly 0.133... Hz.
If a wave has a frequency of 15 Hz, it has a period of?
1/15 s
What frequencies of sound can humans hear?
typically 20-20000 Hz - but this range will decrease with age
What hz is best for headphones?
30 (or lower) to 15 000 (or higher)
How is 60hz in decibel?
Hz is a measure of frequency. Decibel is a measure of loudness/volume/amplitude. The two can not be equated.
A 6 pole induction motor is connected to a 415v50hz mainsIt runs at a speed of 960 rpmCalculate the answer of synchronous speed?
Answer 1000 RPM or 16.667 HZ, 50 Hz * 60 = 3000 RPM 3000 / 3 = 1000 RPM, or 50 HZ / 20 (1/3 of 50 Hz) * 60 seconds. Or Hz * 20 ( converts to RPM) For 4 pole then, Hz * 30 = RPM For 8 pole, Hz * 15 = RPM
What is the volume of a cube with an edge of 15 Cm?
Volume = edge3 = (15 x 15 x 15) = 3,375 cm3
How many waves from a single ray of ultraviolet light with a frequency of 1.2x1015 Hz does your skin absorb during a one hour exposure?
a frequency of 1.2x10^15 Hz
What is the Hz of an ocean wave?
-- If the ocean waves lap the shore every 15 seconds then their frequency is 1/15 Hz.-- If the waves come every 30 seconds then the frequency is 1/30 Hz.-- If the waves come every minute (60 seconds) then their frequency is 1/60 Hz....etc.In general, the frequency of ocean waves, and any other waves, is1/the number of seconds between consecutive waves
What is the frequency in Hz and kHz if the period of oscillation is 7.5 ms?
Frequency = 1/period1/7.5 x 10-3 = 1331/3 Hz = 2/15 KHz
Can you make 15 volume developer using 30 volume and 40 volume?
NO. If you mix them in equal parts, that would give you 35 volume. To get 15 volume, mix equal parts of 10 and 20 volume.
If the photon has a frequency of 4 x 10-15 Hz how did the energy of the electron change?
4x 1015 Hz The electron lost 2.6 x 10-18 J of energy.
