- Variable stars are ones whose brightness varies periodically. The brightness of a certain star is modeled by the function b(t) = 8.2 − 2.7 cos ((pi/155)t) where t is measured in days. (a) Find the period. days(b) Find the maximum and minimum brightness. (minimum) (maximum)arrow_forwarda Cepheid variable star is a star whose brightness alternately increases and decreases. For a certain star, the interval between times of maximum brightness is 6.5 days. The average brightness of this star is 3.0 and its brightness changes by ±0.35. In view of these data, the brightness of the star at time t, where t is measured in days, has been modeled by the function B(t) = 3.0 + 0.35 sin (2?t)/(6.5) A) find the rate of change of the brightness after t days. dB/dt= B) find, correct to two decimal places, the rate of increase after one day. dB/dtarrow_forwardA particle has γ=18,399. a) Calculate c-v in m/s. (I would have asked for 1 - v/c, making the answer dimensionless, but the system doesn't seem to take numbers that small. Gamma is chosen to make the particle extremely close to the speed of light.) If your calculator gives problems, you might want to solve the appropriate equation for c-v or c(1 - v/c) and use an approximation. b) In a race to the moon, by 3/4ths the distance, light is one or ten meters ahead of the particle. We routinely approximate mass as zero, gamma as infinite, and speed as the speed of light. ("Massless particles" -- gamma and m have to be eliminated from the expressions. Light is a true massless particle.) If a massless particle has momentum 1,739 MeV/c, calculate its energy in MeV. Thank you so much!!arrow_forward

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.
