Answer:

C. The object moves in the direction of the stronger force.

Step-by-step explanation:

A.) The object remains stationary.

- Cannot be since an outside force is applied, the net force is uneven, making the object move

B.) The object moves with the same velocity.

The object at rest has the velocity of 0m/s and since an outside force is exerted the object moved.

C.) This statement is correct since the object moved towards the direction the force is applied.

D.) Another wrong statement; unbalanced force is applied, the object moved.

Answer:

Step-by-step explanation:

Let the two perfect cubes be x and y where x > y.

According to the given conditions:

${x}^{3} - {y}^{3} = 386...(1) \\ y = 7...(2) \\ plug \: y = 7 \: in \: equation \: (1) \\ {x}^{3} - {7}^{3} = 386 \\ {x}^{3} - 343 = 386 \\ {x}^{3} = 343 + 386 \\ {x}^{3} = 343 + 386 \\ {x}^{3} = 729 \\ x = \sqrt[3]{729} \\ x = 9$

Thus the cube root of the larger number is 9.

Step-by-step explanation:

given $\left | x+3 \right |$ -2=0

$\left | x+3 \right |$ =2

x+3=+2

x=-1, also, x+3=-2

x=-2-3=-5

hence x=-1 , -5 answer
