Answer:
A. .2 M/s2
Explanation:
Force = mass x acceleration
The force is given as 20 N and tthe mass as 100kg
Solve for accelartion as 20/100 = .2
(Also wrong subject this is a Physics problem)
dont use that link its bad
Answer: 0.18 M
Explanation:
Initial molarity, M1 = 0.8 M
Initial olume, V1 = 225 ml
Final volume, V2 = 1000 ml
Final Molarity, M2 = M1V1/V2
= 0.8 x 225/1000
= 0.18 M
pV = nRT
p = nRT/V
p= 1 x 0.08205 x 1000/ 2
p = 41.025 Pa
Edit: The unit should be atm instead of Pa, as pointed out by a nice human being.
