The chemical name for laughing gas is dinitrogen oxide. the two elements found in a sample of this gas are

scientific laws are the result of testing theories and proving them to be facts.

grav force prop 1/r squared 2r all squared is 4rsquared 1/4rsquared quartered

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

it would be c. predictability
