Use the range equation to predict both of the launch angles that will result in a range of 13.0 m with an initial velocity of 12 m/s and standard Earth gravity. Remember the supplementary angle identity for the sine function: sin(φ)=sin(180°−φ)

Because the sun is the biggest and if the sun orbits the earth we will be dead probably

Answermuscle strength;

Year  1936,  lehman predicted that the earths 'inner core' is solid. she observed that the seismic signals during her study were bent and did not pass through instead bouncing back. later it was confirmed that the earth's inner core was solid made up of nickel-iron and had a molten outer core.
