When a given object moves on a circular path, the centripetal force varies directly as the square of the velocity and inversely as the radius of the curve. The force is 640 pounds for a velocity of 20 miles per hour and radius of 5 meters. The force for a velocity of 30 miles per hour and radius of 4 meters would be blank pounds.

For the following sequence determine the common difference (if it is an arithmetic sequence) or the common ratio (if it is a geometric sequence).

Acompany manufactures large valves, packed in boxes. a shipment consists of 1500 valves packed in 75 boxes. each box has the outer dimensions 1.2 x 0.8 x 1.6 m and the inner dimensions 1.19 x 0.79 x 1.59 m. the boxes are loaded on a vehicle (truck + trailer). the available capacity in the vehicle combination is 140 m3. each valve has a volume of 0.06 m3. - calculate the load factor on the box level (%). - calculate the load factor on the vehicle level (%). - calculate the overall load factor (%).

Anyone? 15m is what percent of 60m; 3m; 30m; 1.5 km?
