Carbon Monoxide is a mixture because its a simple compound with 2 elements, carbon and oxygen are bonded together
Answer:
B. for an object that floats
Explanation:
For an object to float the weight of the object must be balanced by the buoyancy force.
However an object will sink if the magnitude of the buoyant force is equal to the weight of the amount of fluid that has the same volume as the object.
Answer:
Force must be applied to m₁ to move the group of rocks from the road at 0.250 m/s² = 436 N
Explanation:
Total force required = Mass x Acceleration,
F = ma
Here we need to consider the system as combine, total mass need to be considered.
Total mass, a = m₁+m₂+m₃ = 584 + 838 + 322 = 1744 kg
We need to accelerate the group of rocks from the road at 0.250 m/s²
That is acceleration, a = 0.250 m/s²
Force required, F = ma = 1744 x 0.25 = 436 N
Force must be applied to m₁ to move the group of rocks from the road at 0.250 m/s² = 436 N
