For an object to remain at rest, which of the following must be true? question 2 options: the foreces on it are balanced , there is not friction , gravity does not act on it , the onject has no mass.

For an object to remain at rest, the forces acting on the object are balanced.

According Newton's second law of motion, when a force is applied on an object, the object tends to move in the direction of the applied force. This occurs when there is unbalanced force acting on the object.

F = ma

However, if the forces acting on the object is balanced, the object remains at rest or in equilibrium position.

Thus, we can conclude that, for an object to remain at rest, the forces acting on the object are balanced.

your answer would be “dry”

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
