- 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 Hzarrow_forward5.5.For each truth table below, derive a standard SOP and a standard POS expression respectively.

- Please help me. Make sure to give clear answers for all the parts they are attached as 2 screenshots and this problem has 2 parts.arrow_forward(a) Seismographs measure the arrival times of earthquakes with a precision of 0.100 s. To get the distance to the epicenter of the quake, geologists compare the arrival times of S- and P-waves, which travel at different speeds. If S- and P-waves travel at 4.00 and 7.20 km/s, respectively, in the region considered, how precisely can the distance to the source of the earthquake be determined? (b) Seismic waves from underground detonations of nuclear bombs can be used to locate the test site and detect violations of test bans. Discuss whether your answer to (a) implies a serious limit to such detection. (Note also that the uncertainty is greater if there is an uncertainty in the propagation speeds of the S- and P-waves.)arrow_forwardConsider the equation s=s0+v0t+a0t2/2+j0t3/6+s0t4/24+ct5/120 , were s is a length and t is a time.

- Describe the following physical occurrences as events, that is, in the form (x, y, z, t): (a) A postman rings a doorbell of a house precisely at noon. (b) At the same lime as the doorbell is lung, a slice of bread pops out of a toaster that is located 10 1T1 from the door in the east direction from the door. (c) Tell seconds later, an airplane arrives at the airport, which is 10 km from the door in the east direction and 2 km to the south.arrow_forwardThe "classical" radius of a neutron is about 0.81 fm (1 femtometer = 10-15 m). The mass of a neutron is 1.675×10-27 kg. a) Assuming the neutron is spherical, calculate its density in kilograms per cubic meter. b) What would be the magnitude of the acceleration due to gravity, in meters per second squared, at the surface of a sphere of radius R = 1.2 m with this same density? Recall that the gravitational constant is G = 6.67 × 10-11 m3/kg/s2.arrow_forwardThe distance to a star is approximately 4.43 ✕ 1018 m. If this star were to burn out today, in how many years would we see it disappear?
