Neutrons do not carry an electrical charge so adding or removing them from the nucleus does not change the electrical charge of the nucleus. ... So, adding or removing protons from the nucleus changes what element that atom is! For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium.
Is is found in the noble gases group
A dummy is fired vertically upward from a canon with a speed of 40 m/s. How long is the dummy in the air? What is the dummies maximum height?
v=u-at
0=40-10xt
t=4 secs
height = ut-1/2at^2
height= 40x4-1/2x10x4^2
height = 160-5x16
height=160-80=80m

Answer:
Thus, the time for the remaining 120 miles: 8.5 - 6 = 2.5 h
Explanation:
The remaining 120 miles was (1 - 5/9 = 4/9) of the total journey.
Then, total distance: 120 ÷ 4/9 = 120 × 9/4 = 270 miles
The distance for 25 mph: 270 × 5/9 = 150 miles
The time for 25 mph: 150 ÷ 25 = 6 h
