Why do we move backwards when the jeepney started to move?
Why do we move backwards when the jeepney started to move? Explanation: when a vehicle accelerates and suddenly applies a break we posses what we call inertia. and when it suddenly applies a break we tend to retain that velocity so we fall backwards thus satisfying the law of inertia or what is also called […]
What is the role of the independent variable?
What is the role of the independent variable? An independent variable is defines as the variable that is changed or controlled in a scientific experiment. It represents the cause or reason for an outcome. Independent variables are the variables that the experimenter changes to test their dependent variable. What is a true independent variable? The […]
What is the relationship between temperature and vapor pressure?
What is the relationship between temperature and vapor pressure? The vapor pressure of a liquid varies with its temperature, as the following graph shows for water. The line on the graph shows the boiling temperature for water. As the temperature of a liquid or solid increases its vapor pressure also increases. Conversely, vapor pressure decreases […]

Why is the sun so loud?
Why is the sun so loud? The answer might surprise you, as solar physicists estimate that the solar surface noise would be approximately 100dB by the time it reaches Earth! The enormity of the sun’s surface paired with its capability of generating of tens of thousands of watts of sound energy per meter makes the […]

What is difference between gas turbine and steam turbine?
What is difference between gas turbine and steam turbine? The primary difference between steam and gas turbines is the fact that steam turbines receive power from expanding steam. Fuels such as natural gas can heat condensed water in a boiler, but it’s also possible to utilize renewable thermal energy for this heating. This water-based cycle […]
Why is the cell membrane The most important organelle?
Why is the cell membrane The most important organelle? The Cell membrane surrounds all living cells and is the most important organelle, there is also a similar plasma membrane that surrounds all the organelles except for the ribosome. The hydrophobic layer acts as a barrier to all but the smallest molecules and effectively isolating the […]
