101.0 MHzMHz (typical frequency for FM radio broadcasting). 102.4 MHzMHz (typical frequency for FM radio broadcasting) Express your answer in joules using four significant figures. E=____ J
true or false. I- The speed of light in vacuum is a universal constant, whose value (without uncertainty, as it is defined as a standard) is c=299792458 m.s -1..The value of c in scientific notation is 2.99792458 x108 m.s-1. II- The value of c (velocity of light in vacuum) written to 3 significant figures is 3.00 x 108 .m.s-1. III- The value of the density of an object obtained was ρ±uρ=(7.768581114 ± 0.012540242) g.cm -3. The value obtained for the density and its respective uncertainty is incorrect, as it makes no sense to report the uncertainty with so many decimal places. IV- To convert g/cm 3 to kg/m 3 just multiply by 10 3.

Sunspots vary in number as a function oftime, exhibiting an approximately 11-year cycle. Galileo made thefirst European observations of sunspots in 1610, and daily observations were begun in Zurich in 1749. At the present time we are wellinto the 24th observed cycle. What is the frequency of the sunspotcycle? Give your answer in Hz
The planet Venus orbits the Sun in periodic motion (as yearly motion) and simultaneously spins about its axis (as diurnal motion). Venus has a (yearly) period of orbit of 225 days and a (diurnal) period of rotation of 243 days. So for Venus inhabitants, a day would last longer than a year! Determine the frequency of orbit and the frequency of rotation (in Hertz) on Venus. O For yearly motion 5.1 x 108 Hz, For diurnal motion — 4.8 х 108 Hz, O For yearly motion + 1.7 x 108 Hz, For diurnal motion 1.8 x 10-8 Hz, O For yearly motion → 2.5 x 106 Hz, For diurnal motion + 1.8 х 107Hz, O For yearly motion → 4.3 x 107 Hz, For diurnal motion → 48.0 x 10-7 Hz,
In the video, I show measurements of light intensity (measured in lux) from a flashlight at several distances. With the light off, the ambient room light was 194 lux. At 10 cm, the light sensor read 2755 lux. Unfortunately, the flashlight flickered at 20 cm and the reading wasn't accurate.Physics tells us that light intensity varies inversely with the square of the distance, or in other words, it should follow the equation L=kx2+LambientL=kx2+LambientL is the light intensity, in luxk is some constantx is the distance from the light to the sensorLambient is the ambient room light, in luxUsing the given data, complete the equation for light intensity in terms of distance, x.L = Use your equation to predict what the light measurement at 20cm should have been, to the nearest lux. luxIf we wanted a light intensity of 1700 lux, at what distance should we place the light. Give your answer to at least 1 decimal place. 13 cm
