the table shows the masses of four objects. which object has a weight of about 22.5 n?\n|object|mass…

Explanation:

Step1: Recall weight formula

Weight $W = mg$, where $g = 9.8\ m/s^{2}\approx10\ m/s^{2}$, $m$ is mass.

Step2: Calculate weight of book

For book with $m_{1}=1.1\ kg$, $W_{1}=m_{1}g = 1.1\times10=11\ N$.

Step3: Calculate weight of rock

For rock with $m_{2}=2.3\ kg$, $W_{2}=m_{2}g=2.3\times 10 = 23\ N$.

Step4: Calculate weight of box

For box with $m_{3}=4.5\ kg$, $W_{3}=m_{3}g = 4.5\times10=45\ N$.

Step5: Calculate weight of fish

For fish with $m_{4}=5.8\ kg$, $W_{4}=m_{4}g=5.8\times10 = 58\ N$.

Answer:

the rock
