User: 4. A block has a volume of 0.07 m3 and a density of 3,500 kg/m3. What's the force of gravity acting on the block (and weight) in the air? A. 2,401 N B. 2,058 N C. 686 N D. 1,715 N

Weegy: W = mass * acceleration and the gravity acceleration is know as 9.81 m/s^2 so we need to calculate the mass , from the givens , mass = density * volume m= 3500*0.07 = 245 kg subs. in W = m*g , W= 245 * 9.8 = 2401 N D. 2,401 N
