If the mass of an object is 2500, what is the minimum force required to lift it, if the net force applied to the object is -6?

Answer : F = 24494 N

Explanation :

It is given that,

mass of object,

net force on object,

Net force is equal to the sum of forces acting on the object,

On lifting the object, two forces will act i.e. its weight and the muscular force

Let F is the minimum force required to lift the object.

   (since both forces are acting in opposite directions)

Hence, to lift the object minimum force of 24494 N is required.

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
