Answer the following question given this paragraph: 8.1 Linear Momentum and Force Linear Momentum The scientific definition of linear momentum is consistent with most people's intuitive understanding of momentum: a large, fastmoving object has greater momentum than a smaller, slower object. Linear momentum is defined as the product of a system's mass multiplied by its velocity. In symbols, linear momentum is expressed as. Q: The product of a system's mass multiplied by its velocity is called what? Choices: - variation momentum - magnetic momentum - horizontal momentum - linear momentum A:
linear momentum

Answer the following question given this paragraph: 4. Molecular crystals -- Molecular crystals typically consist of molecules at the lattice points of the crystal, held together by relatively weak intermolecular forces (see Figure below ). The intermolecular forces may be dispersion forces in the case of nonpolar crystals, or dipole-dipole forces in the case of polar crystals. Some molecular crystals, such as ice, have molecules held together by hydrogen bonds. When one of the noble gases is cooled and solidified, the lattice points are individual atoms rather than molecules. In all cases, the intermolecular forces holding the particles together are far weaker than either ionic or covalent bonds. As a result, the melting and boiling points of molecular crystals are much lower. Lacking ions or free electrons, molecular crystals are poor electrical conductors. Q: What crystals consist of molecules at the lattice points of the crystal, held together by relatively weak intermolecular forces? Choices: - quartz crystals - salt crystals - healing crystals - molecular crystals A:
(Answer)
molecular crystals
Ques: Answer the following question given this paragraph: Macrophages are large WBCs that can also swallow and destroy old and dying cells, bacteria, or viruses. Below, a macrophage is attacking and swallowing two particles, possibly disease-causing pathogens ( Figure below ). Macrophages also release chemical messages that cause the number of WBCs to increase. Q: Macrophages, which can swallow and destroy old and dying cells, bacteria, or viruses, are large types of what cells? Choices: - red blood cells - white brain cells - dendritic cells - white blood cells A:
Ans: white blood cells

Ques:Answer the following question given this paragraph: The spiral structure in the picture is a large organic molecule. Can you guess what it is? Here's a hint: molecules like this one determine who you are. They contain genetic information that controls your characteristics. They determine your eye color, facial features, and other physical attributes. What molecule is it?. Q: What is the distinctive shape of the molecule that contains genetic information? Choices: - cube - conical - cylindrical - spiral A:

Ans:
spiral
