What does rifling do to a bullet? Rifling works by spinning the projectile about its axis, causing gyroscopic forces that spin-stabilize it throughout its flight; tighter rifling will spin a bullet faster, while looser rifling will spin a bullet slower. How far can a 22 bullet travel? around 1.5 miles How do police match a […]
What are three types of models in science?
What are three types of models in science? Physical models, mathematical models, and computer models are common types of scientific models. How are models created? In some situations, models are developed by scientists to try and predict things. Using this information and an understanding of how these cycles interact, scientists are trying to figure out […]
Is a polarizing filter necessary?
Is a polarizing filter necessary? Low light situations won’t benefit from a polarizer because you’ll need all the light you can get for fast shooting. If you want reflections, like in a lake scene, use a circular polarizer so that you can take a shot WITH the polarizer engaged and another shot WITHOUT the polarizer […]
What are the basis of goals of science education?
What are the basis of goals of science education? Remember that the goal of science education is to teach students to: Use and interpret science to explain the world around them. Evaluate and understand scientific theories and evidence. Investigate and generate scientific explanations. What is the goals of science and technology? What is science and […]
What is meant by the latent heat?
What is meant by the latent heat? Latent heat, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature. The latent heat is normally expressed as the amount of heat (in units of joules or calories) per mole or unit mass of the substance […]
What type of mutation is caused by radiation?
What type of mutation is caused by radiation? Since this is a random process, such effects are now called stochastic. [100] Two important stochastic effects of radiation are cancer, which results from mutations in nongerm cells (termed somatic cells), and heritable changes, which result from mutations in germ cells (eggs and sperm). What is the […]

What is the main difference between a sensory neuron and a motor neuron?
What is the main difference between a sensory neuron and a motor neuron? When we compare motor neuron vs sensory neuron, the main function of Sensory Neurons is to send sensory signals from sensory organs to the central nervous system. Motor Nerves are responsible for sending motor commands from the central nervous system to the […]
