The formula for calculating density, D, is =/, where M represents mass and V represents volume. For liquids, volume is often given in cubic centimeters (cc),which is the same as cm3. If the density of an unknown liquid is 2.1 g/cc, what is the mass of 400 cc of the unknown liquid in grams (g)? * A. 840g
B. 190g
C.005g
D. 8.4g

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
