19.6 is your answer hope this is right
Answer:
Given, Mass of an object, m = 2kg
velocity, v = 2m/s
We have,
KE = 1/2 m v²
= 1/2 × 2 (2)²
= 1/2 × 8
= 4J
Hence, 4J is the required Kinetic energy.
Answer:The solution is in the attached file
Explanation:
40 g Ar.......6.023*10^23 atoms
x g Ar.......3.8*10^24 atoms
x=40*3.8*10^24/(6.023*10^23)=252,365g Ar
