Is a golf ball striking the ground a collision? A golf ball striking the ground is a collision. The ground exerts an equal force on the golf ball. The ground doesn’t exert a force on the golf ball. The force is zero because the golf ball has little mass. Is it bad to hit golf […]
What are the 7 steps to the scientific method?
What are the 7 steps to the scientific method? Let’s build some intuition for the scientific method by applying its steps to a practical problem from everyday life. Make an observation. Ask a question. Propose a hypothesis. Make predictions. Test the predictions. Iterate. What are the six scientific method? Test the hypothesis and collect data. […]
What is the relationship between intensity?
What is the relationship between intensity? indicates the average value of the quantity q.) to describe the medium of propagation. What is the same for all types of waves, the main point here, is that the intensity is proportional to the square of the amplitude. Does voltage increase with light intensity? For the short-circuit current, […]

Why do we need replicates in an experiment?
Why do we need replicates in an experiment? The replication reduces variability in experimental results. Stop of variability increases their significance and the confidence level. Finally, the researcher can draw conclusions about an experimental. Scientists must replicate experiments to ensure validity and account for error. Why is repetition of experiment important? The repetition principle is […]
Which scale is use for absolute zero?
Which scale is use for absolute zero? Absolute zero, temperature at which a thermodynamic system has the lowest energy. It corresponds to −273.15 °C on the Celsius temperature scale and to −459.67 °F on the Fahrenheit temperature scale. Does ratio have a true zero? While interval and ratio data can both be categorized, ranked, and […]
How gravity is created?
How gravity is created? Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. You exert the same gravitational force on Earth that it does on you. But because Earth is so much more massive than you, your force doesn’t really have an […]
