To convert sq.yd to sq.ft, the number of sq.yd should be multiplied by which of the following conversion factors? i. 1 sq.yd/9 sq.ft ii. 9 sq.ft/1 sq.yd d. To convert meters (m) to kilometers (km), the number of meters should be multiplied by which of the following conversion factors? i. 1000 m/1 km ii. 1 km/1000 m e. To convert sq.in to sq.ft, the number of sq.in should be multiplied by which of the following conversion factors? i. 144 sq.in/1 sq.ft ii. 1 sq.ft/144 sq.in f. To convert minutes (min) to seconds (sec), the number of minutes should be multiplied by which of the following conversion factors? i. 60 sec/1 min ii. 1 min/60 sec g. To convert seconds (sec) to minutes (min), the number of seconds should be multiplied by which of the following conversion factors? i. 60 sec/1 min ii. 1 min/60 sec

(Practice) State whether the following variable names are valid. If they are invalid, state the reason. prod_a c1234 abcd _c3 12345 newamp watts $total new$al a1b2c3d4 9ab6 sum.of average volts1 finvolt

(Physics) a. The weight of an object on Earth is a measurement of the downward force onth e object caused by Earth’s gravity. The formula for this force is determined by using Newton’s Second Law: F=MAeFistheobjectsweight.Mistheobjectsmass.AeistheaccelerationcausedbyEarthsgravity( 32.2ft/se c 2 =9.82m/ s 2 ). Given this information, design, write, compile, and run a C++ program to calculate the weight in lbf of a person having a mass of 4 lbm. Verify the result produced by your program with a hand calculation. b. After verifying that your program is working correctly, use it to determine the weight, on Earth, of a person having a mass of 3.2 lbm.

Problem 9

(Automotive) a. An automobile engine’s performance can be determined by monitoring its rotations per minute (rpm). Determine the conversion factors that can be used to convert rpm to frequency in hertz (Hz), given that 1rotation=1cycle,1minute=60seconds,and1Hz=1cycle/sec. b. Using the conversion factors you determined in Exercise 7a, convert 2000 rpm into hertz.
