Question

the weight (w) of an object is given by the formula: w = mg where we know the mass of an object (m) and the gravitational acceleration (g). public static void main(string args) { int mass = 20; int gravacc = 9.8; int weight = ? system.out.println(\the weight of the object is \ + weight); } which expression completes the calculation for the weight of the object? mass gravacc object gravacc weight gravacc

Explanation:

Step1: Recall weight formula

The weight formula is $W = m\times g$, where $m$ is mass and $g$ is gravitational - acceleration. In the given code, mass is represented by "mass" and gravitational acceleration by "gravAcc".

Step2: Identify correct expression

To calculate weight, we multiply mass and gravitational acceleration. So the correct expression is "mass * gravAcc".

Answer:

mass * gravAcc
