Boron Group
elements have three valence electrons and are fairly reactive. All of them are solids at room temperature. Boron is a very hard, black metalloid with a high melting point.
Answer:5.075N
Explanation:
Mass=0.145kg
Acceleration=35m/s^2
Force=mass x acceleration
Force=0.145 x 35
Force=5.075N
This is an example of state change from solid to liquid.
