Free fall without air resistance:
g=9.81 m/s²
t=235 s
h=?
h=0.5*g*t²
h=0.5*9.81*235²
h=270879m =270 km
When two vectors are in same direction then we add up to get their resultant and in this case resultant would be maximum
R = A + B
R = 4 + 2
R = 6
If vectors are in opposite direction then they provide minimum resultant and in this case we subtract them
R = A - B
R = 4 - 2
R = 2
Answer:
20 m/s
Explanation:
The relevant relationship is ...
speed = distance/time
speed = (100 m)/(5 s) = (100/5) m/s
speed = 20 m/s
The average speed is 20 meters per second.
Answer:
Atomic size gradually decreases from left to right across a period of elements.
Explanation:
This is because, within a period or family of elements, all electrons are added to the same shell. However, at the same time, protons are being added to the nucleus, making it more positively charged.
