Final answer:
To determine the force in cord ABC, we calculate the tension in the cord, which is equal to the weight of the hanging block. In this case, the tension in cord ABC is 9.8 N.
Step-by-step explanation:
To determine the force in cord ABC, we need to calculate the tension in the cord. The tension in the cord can be found by considering the forces acting on the hanging block.
First, calculate the weight of the hanging block by multiplying its mass (1.0 kg) by the acceleration due to gravity (9.8 m/s^2). This gives us a weight of 9.8 N.
Next, consider the forces acting on the hanging block. The tension in the cord (T) is equal to the weight of the block (9.8 N) plus any additional force required to accelerate the block. Since the block is not accelerating in this problem, the tension in the cord is simply equal to its weight, which is 9.8 N.
