Answer the following question given this paragraph: In the single fixed pulley, only one rope segment pulls up on the load, so the ideal mechanical advantage is 1. In other words, this type of pulley doesn't increase the force that is applied to it. However, it does change the direction of the force. This allows you to use your weight to pull on one end of the rope and more easily raise the load attached to the other end. Q: What is the ideal mechanical advantage in the single fixed pulley? Choices: - zero - 2 - 4 - 1 A:
1

Answer the following question given this paragraph: An ionic crystal lattice breaks apart when it is dissolved in water. Dissociation is the separation of ions that occurs when a solid ionic compound dissolves. It is important to be able to write dissociation equations. Simply undo the crisscross method that you learned when writing chemical formulas of ionic compounds. The subscripts for the ions in the chemical formulas become the coefficients of the respective ions on the product side of the equation. Shown below are dissociation equations for NaCl, Ca(NO 3 ) 2 , and (NH 4 ) 3 PO 4 . Q: What do you call the separation of ions that occurs when a solid ionic compound dissolves? Choices: - deformation - decomposition - dissolution - dissociation A:
dissociation

Answer the following question given this paragraph: Physical science is the study of matter and energy. That covers a lot of territory because matter refers to all the "stuff" that exists in the universe. It includes everything you can see and many things that you cannot see, including the air around you. Energy is also universal. It's what gives matter the ability to move and change. Electricity, heat, and light are some of the forms that energy can take. Q: What branch of science is the study of matter and energy? Choices: - unnatural science - natural science - negative science - physical science A:
physical science
