Answer: 3m/s2
Explanation:
Force =24 N
Mass = 8kg
Acceleration =?
Force = Mass x Acceleration
Acceleration = Force /Mass = 24/8 = 3m/s2
Answer:
105
Explanation:
Density = mass/volume
therefore volume = mass/density
826/7.9=105 (To three significant figure)
N(C)=5,02·10²² atoms
calculation check:
N(C)=(1/12)*6.022*10²³=0.5018*10²³≈5.02·10²²
Answer:
The answer is B
Explanation:
The answer is B because representative particles can only be atoms.
