Answer:

B. for an object that floats

Explanation:

For an object to float the weight of the object must be balanced by the buoyancy force.

However an object will sink if the  magnitude of the buoyant force is equal to the weight of the amount of fluid that has the same volume as the object.

steposvetlana [31]
The electric potential energy of the electron depends on the potential difference applied between the two ends of the cable. Indeed, the electric potential energy of a charge is given by
U=q \Delta V
where q is the magnitude of the charge, while \Delta V is the potential difference applied. So, U depends on \Delta V.

a 3000 kg and a 7000 kg Mass attract each other with a force of 0.0015 N. What distance separates the two objects (Radius) (Plea
frutty [35]

Answer:

<h3> 3.057m</h3>

Explanation:

According to law of gravitation;

F = GMm/d²

G is the universal gravitation

M and m are the masses

d is the distance between the masses

d² = GMm/F

d² = 6.67408 × 10-11 *3000*7000/0.0015

d² = 140.15568*10^-5/0.0015

d² = 1.4016*10^-3/0.0015

d² = 1.4016*10^-3/1.5*10^-3

d²  = 0.9344*10

d² = 9.344

d = √9.344

d = 3.057m

Hence the distance between the two objects is  3.057m
