Is gravitational force attractive in nature? We all know that all the forces in nature exist in opposites, but gravitational force is the only force that always attracts every object and never reples any. What is gravitational force is always in nature? (c) Gravitational force is always independent of other masses in the surroundings. How […]
What are the three layers of the earth answer?
What are the three layers of the earth answer? The Earth is divided into three main layers. The dense, hot inner core (yellow), the molten outer core (orange), the mantle (red), and the thin crust (brown), which supports all life in the known universe. Earth’s interior is generally divided into three major layers: the crust, […]
What is the internal resistance of a 12v car battery?
What is the internal resistance of a 12v car battery? 0.02 ohms What is the internal resistance of the battery? Though the internal resistance may be or appear low, around 0.1Ω for an AA alkaline battery, and about 1Ω to 2Ω for a 9-volt alkaline battery, it can cause a noticeable drop in output voltage […]
What is the formula of packing efficiency?
What is the formula of packing efficiency? Packing efficiency can be written as below, Packing efficiency = Volume occupied by 6 spheres ×100 / Total volume of unit cells. Examples are Magnesium, Titanium, Beryllium etc. In body-centered cubic structures, the three atoms are arranged diagonally. Which crystal structure has the greatest packing efficiency? Crystal Structure: […]
What helps the cell maintain its shape?
What helps the cell maintain its shape? The cytoskeleton is a structure that helps cells maintain their shape and internal organization, and it also provides mechanical support that enables cells to carry out essential functions like division and movement. How is sugar broken down into carbon dioxide? Through the process of cellular respiration, the energy […]
How do you know what the dependent variable is?
How do you know what the dependent variable is? The variables in a study of a cause-and-effect relationship are called the independent and dependent variables. The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent […]
Is physics a respected degree?
Is physics a respected degree? Physics degrees are highly respected by employers and offer ample career opportunities. The workload can be quite heavy and the hours are long, but if you’re enthusiastic about unravelling the secrets of the universe, it’s a great choice. Where can a physics degree take you? Jobs directly related to your […]
Is the changing of liquid water to water vapor?
Is the changing of liquid water to water vapor? Evaporation – Evaporation happens when heat from the Sun turns liquid water into water vapor (gas). About 90% of the water in the atmosphere comes from evaporation. Most evaporation occurs in the oceans, because they cover so much of Earth’s surface. Why do we see droplets […]
Is fog caused by temperature inversion?
Is fog caused by temperature inversion? Sound is affected during fog conditions due to the small distances between water droplets, and air temperature differences. Temperature effect: A fog can be caused by a temperature inversion where cold air is pooled at the surface which helped to create the fog, while warmer air sits above it. […]
Why do insects not die from falling?
Why do insects not die from falling? So the resistance to falling in the case of the small animal is relatively ten times greater than the driving force. An insect, therefore, is not afraid of gravity; it can fall without danger, and can cling to the ceiling with remarkably little trouble. Is it OK to […]
