For each beaker, determine how much the temperature changed in the first 100 seconds and how much it changed between 500 and 600 seconds. Compare this to the temperature difference between the beakers at the start of each interval.

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

find the sum of the two horizontal vectors and the sum of the two vertical vectors
