3. Mr. Garcia’s science class was studying energy and ways to cut energy costs. All of the students were to compare his or her electric bill for October to the one they would receive in November. All of the students would have a list of energy-saving tips that they would follow during November. Which would be the MOST uncontrollable factor in their investigation? (SC.6.N.1.1) A. the list of energy-saving tips to follow B. The outdoor temperature in November C. the amount of time given to the investigation D. the accuracy of the October and November bills

i think it would be 5

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
