What is the hardest branch of physics? The hardest thing that an undergraduate physics students must learn is the classical dynamics of spinning tops (also called “rigid bodies” in this context)….This Is The Hardest Concept To Grasp In Physics (Hint: It’s Not Relativity) Share to Facebook. Share to Twitter. Share to Linkedin. Who is the […]

What does the shape of a histogram tell you about the data? Uniform: A uniform shaped histogram indicates data that is very consistent; the frequency of each class is very similar to that of the others. The mean of right-skewed data will be located to the right side of the graph and will be a […]

Why we Cannot drink lemonade on moon? On the Moon, an astronaut cannot drink lemonade with the help of straw because. acceleration due to gravity on the Moon is less. lemonade evaporates instantaneously on the Moon. Will a drinking straw work on Moon? It can’t, because there is no such force as “suction,” only atmospheric […]

Do Fireworks cause sonic boom? Fireworks generate three very noticeable forms of energy: a tremendous release of sound, bright light, and heat. The tremendous booms heard at ground level are the result of the rapid release of energy into the air, causing the air to expand faster than the speed of sound. This produces a […]

Why is it important to reduce energy usage? First of all, reducing energy use limits the number of carbon emissions in the environment. In turn, conserving energy produces a higher quality of life. Reduced emissions result in cleaner air quality. In addition, it helps create a healthier planet, or at least helps sustain the resources […]

Why the egg is less likely to break when dropped onto soft foam rather than onto a concrete floor? When the egg is dropped on a hard surface, dt is small thus F is large enough to break the egg. If it’s dropped on a soft surface, it still undergoes the same change in momentum, […]

What is the human cause of climate change? Humans are increasingly influencing the climate and the earth’s temperature by burning fossil fuels, cutting down forests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming. What is a natural climate change? […]

What is phase difference measured in? Phase difference: The time interval by which a wave leads by or lags by another wave is called “Phase difference” or “Phase angle”. It is defined by ‘Φ’. The phase angle is measured in “Radians / Sec” or “Degrees / Sec” and the phase of a complete cycle is […]

Should I unplug appliances when not in use? The energy costs of plugged-in appliances can really add up, and unplugging these devices could save your up to $100 to $200 a year. Another benefit of unplugging your appliances is protection from power surges. Should I unplug microwave when not in use? People typically remember to […]

What are limiting factors for humans? Limiting factors are resources or other factors in the environment that can lower the population growth rate. Limiting factors include a low food supply and lack of space. Limiting factors can lower birth rates, increase death rates, or lead to emigration. What are three limiting factors for human population? […]
