Answer:
H2O is a polar molecule
the H is slightly positive and the O is slightly negative so the Na is attracted to the O side of the water molecule and the Cl is attracted to the H side of the water molecule
Explanation:
v = 75 mph = 33.52 m/s
u = 55 mph = 24.58 m/s
t = 4 sec
acceleration = v-u/t
= 33.52-24.58/4
= 8.94/4
= 2.235 m/s
