What is an equilibrant?
(Points : 1)
an object that has zero net force acting on it
two chemical reactions proceeding at the same rate in opposite directions
a force that makes the net force on an object zero
a force in the same direction as the net force <--
Question 2. 2. How is the equilibrant related to the net force?
(Points : 1)
It is equal in magnitude and opposite in direction.
It is equal in magnitude and acts in the same direction.<--
It is always smaller in magnitude than the net force.
It is always larger in magnitude than the net force.
Question 3. 3. Which of these statements is always true?
(Points : 1)
If an object is moving, a net force is acting on it.
An object in equilibrium must not be in motion.
A moving object in equilibrium continues at a constant velocity.<--
A moving object in equilibrium can change its direction but not its speed.
Question 4. 4. This handbag exerts a force of 10 N on the hook. Which of the following values is a possible tension for each side of the cloth loop on the handbag? Each side of the loop exerts a vertical force only, not a horizontal force, on the rest of the handbag.

7. 90 N.
number 1 is c and I got 5/6 still
for question number 4.4 I selected b is this correct?
yes it is correct!!!
Zachary is correct.. but number 7 is 120
Question 1: An equilibrant is a force that makes the net force on an object zero. The correct answer is "a force that makes the net force on an object zero".
Question 2: The equilibrant is equal in magnitude and acts in the opposite direction of the net force. The correct answer is "It is equal in magnitude and opposite in direction".
Question 3: A moving object in equilibrium continues at a constant velocity. The correct answer is "A moving object in equilibrium continues at a constant velocity".
Question 4: The tension in each side of the cloth loop on the handbag can be equal to the force exerted by the handbag on the hook, which is 10 N. The correct answer is "10 N".
Question 5: To find the tension in each wire, we need to resolve the weight of the picture and frame into its components along the two wires. Since each wire makes an angle of 45º with the horizontal x-axis, the tension in each wire can be found using trigonometry. The correct answer is "8.5 N".
Question 6: The vertical force that the wire exerts on the picture hook supporting it can be found by summing up the vertical components of the tension in each side of the wire. Since each side of the wire exerts a tension of 17 N, the vertical force can be found using trigonometry. The correct answer is "24 N".
Question 7: The boulder does not move, which means the net force on the boulder is zero. Since one worker is pushing north and the other is pushing east, the horizontal component of the force that the ground exerts on the boulder must be equal in magnitude but opposite in direction to the horizontal components of the workers' forces. The correct answer is "0 N".
