Answer: copper > chalk > flour > talcum powder > dry beans.
Explanation:
Density is the compactness of given object.
Basically, it is mass per volume.
copper has the most density
chalk has lesser density than copper.
flour has lesser density than copper and chalk.
talcum powder has lesser density than copper, chalk and flour.
dry beans have lesser density than copper, chalk, and flour.
So, it becomes,
copper > chalk > flour > talcum powder > dry beans.
By Newton's second law, the net force on the object is
∑ F = 10.0 N + F = (7.0 kg) (1.0 m/s²)
where F is the unknown force. Since the object is accelerating to the east, F must be acting in the same or opposite direction as the known force that is also directed eastward. Solve for F :
10.0 N + F = 7.0 N
⇒ F = - 3.0 N
which is to say, F has magnitude 3.0 N and points toward the west.
