Answer:
6000N
Explanation:
Force = Mass x Acceleration
= 3000 x 2
= 6000 kg m/s^2 or 6000N
Letter A would sound about right.
Answer:
it's a double displacement reaction
Explanation:
Answer:
The ratio of the amounts of U 238 and Pb 206 in a rock sample enables the age of the rock to be estimated using the technique of radiometric dating. It moves back in the periodic table until the isotope falls in the band of stability at Pb 206.
N(NaOH)=0.0688 mol
v=0.250 L
c=n(NaOH)/v
c=0.0688/0.250=0.2752≈0.28 mol/L
0.28 M
