PART A: OBJECTIVES 1. The form of oxygen that cannot exist freely in nature is atomic oxygen. A. O 2. Ions are not fundamental particles of an atom; they are atoms that have gained or lost electrons. B. Ions 3. Crystalline compounds have a regular, ordered structure, which results in a specific temperature at which all bonds break simultaneously. True 4. The regular arrangement of atoms in a crystal is known as a crystal lattice. C. Lattice 5. Step 1: Identify the given values and the formula for Hooke's Law. Given force F = 20\, N and extension x = 2\, m. Hooke's Law states F = kx, where k is the spring constant. Step 2: Calculate the spring constant k. k = (F)/(x) = 20\, N2\, m = 10\, N/m A. 10 N/m PART B: THEORY 1. An atom consists of a central, dense nucleus containing positively charged protons and neutral neutrons. Negatively charged electrons orbit the nucleus in specific energy levels or shells. The number of protons determines the element. 2. • Cohesion is the attractive force between molecules of the same substance. For example, water molecules are cohesive, causing surface tension. • Adhesion is the attractive force between molecules of different substances. For example, water adheres to glass, causing it to climb up a narrow tube (capillary action). 3. Young's Modulus (or modulus of elasticity) is a measure of the stiffness of an elastic material. It is defined as the ratio of tensile stress to tensile strain within the elastic limit of the material. E = Tensile StressTensile Strain = (F/A)/( L/L_0) where F is the applied force, A is the cross-sectional area, L is the extension, and L_0 is the original length. 4. Step 1: Calculate the spring constant (k) using the initial force and extension. Given initial force F_1 = 5\, N and initial extension x_1 = 0.1\, m. Using Hooke's Law, F_1 = kx_1: k = (F_1)/(x_1) = 5\, N0.1\, m = 50\, N/m Step 2: Calculate the new extension (x_2) when the applied force is 20\, N. Given new force F_2 = 20\, N. Using Hooke's Law, F_2 = kx_2: x_2 = (F_2)/(k) = 20\, N50\, N/m = 0.4\, m Step 3: Calculate the total length of the spring. The natural length of the spring L_0 = 0.5\, m. The new total length L_2 = L_0 + x_2: L_2 = 0.5\, m + 0.4\, m = 0.9\, m The length of the spring when the applied force is 20\, N will be 0.9 m. Send me the next one 📸
