The pull of the moon on earth's tidal bulge is causing
the earth to gradually rotate faster
the earth to slowly expand in size
the earth to rotate slightly slower
the moon to move closer to earth

Awave with a frequency of 500 hz is traveling at a speed of 100 m/s.what is the wavelength?

Find the steady-state temperature at the center of the plate = /2, = /2) for sums of w from n=1 to n=19 (only odd values). find the value of n for which the change in /2, /2) is less than 1% from the value at the previous n. at this point, we consider the solution converged. does the value of the temperature at the center seem reasonable? in this part, the values of x and y are constant scalar values. you should produce a plot of the value of n on the horizontal and the estimate of the temperature at the center of the plate on the vertical. b. using the value of n (or larger) that resulted in convergence in part (a), create a contourf plot of the temperature distribution across the entire plate. use enough spatial subdivisions to create a useful plot. comment on the results. hint: you need to determine what “x” and “y” values to use to make your t matrix. i recommend using a different number of x and y values. use enough x and y values so that the plot is “smooth”.

Hi , i am new here can anyone me out with this question why is space black after having so many shining objects like sun , moon , stars
