Explaination:
Block A density:0.0625 kg/cm3
Block B density:0.020833 kg/cm3
Block C density:0.041667 kg/cm3
Answer:
B. Both electric fields and forces ...
Explanation:
Impulse = Ft = Δmv, where F is the average force, t is time, m is mass and v is velocity.
Δmv = m(v₂ - v₁) = 0.2 * (3 - (-4)) = 0.2 * 7 = 1.4
Solve for F.
When two or more elements join together chemically, we have a B. compound.
Water is a compound because of its molecular formula H2O
