Which transition causes the absorption line at the shortest wavelength? Which transition causes the emission line at the shortest wavelength? From the transitions, we can see that energy involved from the transition of E to C is the largest energy involved (longest arrow) which makes it having the shortest wavelength. What is the lowest possible […]
What happened to the alpha particles when they hit the gold foil?
What happened to the alpha particles when they hit the gold foil? Alpha particles only have 2 protons, so the positive charge is not strong enough to attract the electrons in the gold atom. It might have definitely interacted, with the electrons “pulling” them toward themselves, which result in a tiny force which pushed the […]
Do vitamins give energy?
Do vitamins give energy? Vitamin B-12, or cobalamin, is a nutrient you need for good health. It’s one of eight B vitamins that help the body convert the food you eat into glucose, which gives you energy. Vitamin B-12 has a number of additional functions. What are the main source of fresh water? precipitation What […]
What is the purpose of graphite?
What is the purpose of graphite? Graphite is used in pencils and lubricants. It is a good conductor of heat and electricity. Its high conductivity makes it useful in electronic products such as electrodes, batteries, and solar panels. What are the properties of graphite and diamond? Diamond Graphite The geometry is tetrahedral. The geometry is […]
Why is sound not heard in space?
What are two factors that help determine the strength of an electric field at any given point in space?
What are two factors that help determine the strength of an electric field at any given point in space? The new formula for electric field strength (shown inside the box) expresses the field strength in terms of the two variables that affect it. The electric field strength is dependent upon the quantity of charge on […]
Why do people get more injuries when he falls on cemented floor than on sand?
Is it good to take chlorophyll?
Is it good to take chlorophyll? Natural chlorophyll has no known side effects and so far only has benefits for humans. However, chlorophyllin as a supplement may have some possible side effects that you should consider such as: Occasional diarrhea. Discoloration of the urine or feces. How many times a day should I drink chlorophyll? […]
Does a nerve impulse travel faster with myelin or without it?
Does a nerve impulse travel faster with myelin or without it? Myelin speeds up impulses By jumping from node to node, the impulse can travel much more quickly than if it had to travel along the entire length of the nerve fibre. Myelinated nerves can transmit a signal at speeds as high as 100 metres […]
What do V shaped contour lines indicate the presence of?
What do V shaped contour lines indicate the presence of? Widely spaced contour lines indicate that the land is relatively level. A contour line that bends to form a V shape indicates a valley. The bend in the V points toward the higher end of the valley; this V points upstream, or in the direction […]
