Why is Heisenberg uncertainty principle valid for small particles?
Why is Heisenberg uncertainty principle valid for small particles? For phenomena such as the atomic processes, the displacement and momentum are such that they are critically applicable. This is the reason why the uncertainty principle is significant only on the atomic scale because of the small value of h in everyday units. Why is Heisenberg […]
What is the importance of rocks that contain fossils?
What is the importance of rocks that contain fossils? To tell the age of most layered rocks, scientists study the fossils these rocks contain. Fossils provide important evidence to help determine what happened in Earth history and when it happened. What can fossils in a rock tell us? Fossils are the remains or traces of […]
What is the formula for instantaneous speed?
What is the formula for instantaneous speed? Instantaneous speed (v) = distance/ time Instantaneous speed is a scalar quantity. For uniform motion, instantaneous speed is constant. In other words, we can say that instantaneous speed at any given time is the magnitude of instantaneous velocity at that time. What is the instantaneous speed? Definition: When […]

How does no light affect the plants?
How does no light affect the plants? How Light Affects the Growth of a Plant. Plants get energy from light through a process called photosynthesis. This is how light affects the growth of a plant. Without light, a plant would not be able to produce the energy it needs to grow. Does more light mean […]
