Q: What is it called when multiple faults are located in close proximity to one another? Read this paragraph and choose the correct option from the provided answers: If the rocks on one or both sides of a fracture move, the fracture is called a fault ( Figure below ). Faults can occur alone or in clusters, creating a fault zone . Earthquakes happen when rocks break and move suddenly. The energy released causes an earthquake. Choices: - fog zone - crystal zone - solid zone - fault zone A:
fault zone

Q: What causes an elastic force in springs? Read this paragraph and choose the correct option from the provided answers: Springs like the ones in Figure below also have elastic force when they are stretched or compressed. And like stretchy materials, they return to their original shape when the stretching or compressing force is released. Because of these properties, springs are used in scales to measure weight. They also cushion the ride in a car and provide springy support beneath a mattress. Can you think of other uses of springs?. Choices: - velocity - momentum - freezing - stretching or compressing A:
stretching or compressing

Q: Displacement, velocity, acceleration, and force are examples of what type of quantity that has magnitude and direction? Read this paragraph and choose the correct option from the provided answers: Vectors in Two Dimensions A vector is a quantity that has magnitude and direction. Displacement, velocity, acceleration, and force, for example, are all vectors. In one-dimensional, or straight-line, motion, the direction of a vector can be given simply by a plus or minus sign. In two dimensions (2-d), however, we specify the direction of a vector relative to some reference frame (i. , coordinate system), using an arrow having length proportional to the vector's magnitude and pointing in the direction of the vector. Figure 3.9 shows such a graphical representation of a vector, using as an example the total displacement for the person walking in a city considered in Kinematics in Two Dimensions: An Introduction. We shall use the notation that a boldface symbol, such as D , stands for a vector. Its magnitude is represented by the symbol in italics, D , and its direction by . Vectors in this Text In this text, we will represent a vector with a boldface variable. For example, we will represent the quantity force with the vector F , which has both magnitude and direction. The magnitude of the vector will be represented by a variable in italics, such as. Choices: - cycles - wave - frequency - vector A:
vector

Q: Probability can be used to predict the chance of gametes and offspring having certain what? Read this paragraph and choose the correct option from the provided answers: Probability can be used to predict the chance of gametes and offspring having certain alleles. Choices: - molecules - atoms - particles - alleles A:
alleles
