An object weigh 55.54 Newtons what is it's mass if a gravitometer indicates that G = 9.83 m/s² A 0.18 KG

B 5 .67 kg

C 545.95 kg

Explanation:

Weight = Mass * Gravitational force

55.54N = m * 9.83N/kg

Hence m = 55.54 / 9.83 = 5.67kg.

Explanation:

Weight is found by multiplying the mass by the gravitational acceleration.

The weight of the object is 55.54 Newtons and the gravitational acceleration is 9.83 m/s².

Therefore,

Substitute the values into the formula.

Solve for the mass (m) by isolating the variable on one side of the equation. m is being multiplied by 9.83 m/s². The inverse of multiplication is division. Divide both sides of the equation by 9.83 m/s²

The m/s² will cancel each other out, hence the prior unit conversion.

This is about 5.67 kg, so B must be the correct answer.

pure substance: iron,copper

impure substance: water,charcoal
