Mass of the object and the distance between 2 objects of interest. We have the equation ##E_gravity=-GMm/r## ##G## is the universal gravitational constant. ##M## is the […]

1.07 1 inch ##=## 2.54 cm 42 inches ##=## ##42 times 2.54## cm 42 inches ##=## 107 cm 42 inches ##=## 1.07 metres

25 miles per hour is ##25/60## miles per minute. There are 1609.3 metres in a mile. Therefore ##25/60## * 1609.3 = 670.54 metres per minute.

##E/L=b/a## ##Effort-load-fulcrum## ##a: distance between effort and fulcrum## ##b:distance between load and fulcrum## ##E:Effort## ##L:Load## ##E*a=L*b## ##E/L=b/a##

is the force acting on an unit area It can be given as a formula it’s . ##F## = Net force acting on the body . […]

My weight would decrease by 3 times than when I stand on the Earth’s surface. The force of gravity##(F)## of earth is given by## (GMm)/r^2 ## […]

##170m=66929 inch## ##1 inch=254 cm=00254 m## ##170 m=17/(00254)## ##170m=66929 inch##

14.91290861 miles 1 mile = 1.609344 kilometers (google) ##24 km((1 mi) / 1.609344km)##

The answer is: ##33.4kJ## To answer to this question it is sufficient to use this equation: ##Q=Lm## where ##Q## is the amount of heat needed to […]
