Question

Assume 1.2 kg , 4.5 kg , and the objects are wired together by very light, rigid pieces of wire. The array is rectangular and is split through the middle by the x axis. What is the total mass of the objects?

1) 5.7 kg
2) 6.0 kg
3) 5.3 kg
4) 4.2 kg

Answer 1

The total mass of the two objects wired together is 5.7 kg, obtained by adding the masses of 1.2 kg and 4.5 kg together.

Step-by-step explanation:

The question is asking about the total mass of objects that are wired together. Since the given objects' masses are 1.2 kg, 4.5 kg, and the wires are said to be very light and can be ignored, we simply need to add the masses of the two objects to find the total mass of the system.

To find the total mass, you perform the following calculation:

1. Add the mass of the first object (1.2 kg).
2. Add the mass of the second object (4.5 kg).
3. Combine the masses to determine the total mass.

1.2 kg + 4.5 kg = 5.7 kg. This is the total mass of the objects wired together.
