What are the two main functions of cell wall? The main function of the cell wall is to provide structural strength and support, and also provide a semi-permeable surface for molecules to pass in and out of the cell. Where are cell walls found? A cell wall is a fairly rigid layer surrounding a cell […]
What is the difference between stored energy and usable energy?
What is the difference between stored energy and usable energy? The stored energy is termed as potential energy while the working energy is termed as kinetic energy. The electricity used in our homes is also a form of energy because it is a form of usable power. The places from which the different energies are […]
How much force does a falling person have?
How much force does a falling person have? OSHA limits the amount of force that a person should experience during a fall to 1,800 pounds. Forces greater than this can result in internal bleeding, damage, or death. When a personal fall arrest system is used, a shock-absorbing lanyard or fall limiter is the only way […]
What is the 5 step design process?
What is the 5 step design process? The five stages of Design Thinking, according to d. school, are as follows: Empathise, Define (the problem), Ideate, Prototype, and Test. Let’s take a closer look at the five different stages of Design Thinking. What is the difference between scientific investigation and technological design? Scientific inquiry is used […]
What is the smallest unbreakable unit of a compound?
What is the smallest unbreakable unit of a compound? molecule What are the similarities and differences of the two compounds? A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom. Compounds contain different elements in a fixed ratio […]
Why elastic force is called conservative force explain?
Why elastic force is called conservative force explain? A conservative force is a force done in moving a particle from one point to another, such that the force is independent of the path taken by the particle. It depends only on the initial and final position of the particle. Gravitational force and elastic spring forces […]
Why light shines off of a mirror?
Why light shines off of a mirror? A mirror is a surface that reflects light more perfectly than ordinary objects. Most objects reflect light at varying angles. This is more accurately called refraction, because the rays of light bend when they hit the object and move off in varying directions. This allows us to see […]
What are the five changes of state?
What are the five changes of state? Common changes of state include melting, freezing, sublimation, deposition, condensation, and vaporization. What are the 22 states of matter? What are the 22 states of matter? Solid. Liquid. Gas. Plasma. Bose-Einstein Condensate. Excitonium. Degenerate Matter. Photonic Matter. What are the 7 types of matter? The seven states of […]
Why is evaporation important how can it help you?
Why is evaporation important how can it help you? The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. Evaporation is a very important part of the water cycle. Heat from the sun, or solar energy, powers the evaporation process. Once water evaporates, it also helps form […]
Which forest layer has the greatest amount of net primary productivity?
Which forest layer has the greatest amount of net primary productivity? Basic ideas – NPP in terrestrial ecosystems Tropical rain forests have high NPP and the highest biodiversities of any terrestrial ecosystems. The physical environment favours vast photosynthetic output and high growth rate. Which biomes are most affected by humans? Tropical dry forests and temperate […]
