On Earth, gravity adds 9.8 m/s to the downwsrd speed of any falling object, every second. Beginning from zero downward speed, the speed grows to (8 x 9.8) = 78.4 m/s downward after 8 sec.
The snail would travel 100mm
Each minutes is 25mm and it took 4 minutes
4 x 25 = 100
or
25+25+25+25=100
Answer:10 A
Explanation:
According to the KCL (Kirchhoff's current laws)
green pigment in the chloroplast is chlorophyll
Force (F)=Mass (m)×Acceleration (a).
∴F=ma.
∴F=(2kg)×(3ms2).
∴F=6kgms2=6 Newton. =6N.
