Answer:
Caesium
down the group atomic radius increases and along period wise atomic radius decreases
Answer:
1250kg
Explanation:
Given parameters:
Acceleration = 1.2m/s²
Force = 1500N
Unknown:
Mass on the vehicle = ?
Solution:
According to newton's second law of motion:
Force = mass x acceleration
Since mass is the unknown, insert the parameters and solve;
1500 = mass x 1.2
mass = 
= 1250kg
Take the atomic mass of silicon and put it over one. Then set that equal to x over 4.8 x 1026. X will equal to the weight of silicon in grams.
