The period is the reciprocal of the frequency, in other words, one divide by the frequency. If the frequency is in Hertz, the period is in seconds.
To calculate ten percent of a value, multiply the value by 0.1. For example, ten percent of 75 is equal to 75 x 0.1 = 7.5.
25
Divide the numerator by the denominator. For example, 3/4 = 3 divided by four =.75
100 km and 75 km are displacements, NOT velocities. The resultant displacement is 25 km north,
75 + 75 = 150
Frequency = 75 Hz. Speed = 45 m/s
wavelength=velocity/frequency (v/f). wavelength=(3x10/4x10)=30/40=.75 meters
(frequency) multiplied by (wavelength) = (wave speed)
75 mHz
(60*75)/100=45
find 75% of 10 and 75%of 8 then add them together
75
The maxium frequency swing in FM is ± 75 kHz so 75 kHz x 60% = ± 45 kHz
To find what is 75% of 250: 75 ÷ 100 × 250 = 187.5
75*40
75*100
Rhenium (Re) has 75 protons.
