A ball is shot vertically into the air. At its highest point, a. its velocity is -10 m/s and its acceleration is -10 m/s/s.
b. its velocity is 0 m/s and its acceleration is -10 m/s/s.
c. its velocity is -10 m/s and its acceleration 0 m/s/s.
d. its velocity is 0 m/s and its acceleration is 0 m/s/s.

You will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. (refer to the walk-through video to locate the online lab within the online textbook).

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?

According to the image below, which season is about to begin in the southern hemisphere? a. summer b. autumn c. winter d. spring
