What is the difference between Thigmotropism and Thigmotropism? Bitter gourd exhibits thigmotropism as its tendrils show directional movement towards the things they happen to touch…. Thigmotropism Thigmonasty It is a directional movement of plant parts in response to touch. It is a non-directional movement of plant parts in response to touch. What is positive tropism […]
Is momentum conserved in a pendulum?
Is momentum conserved in a pendulum? While not all of the energy from the bullet is transformed into kinetic energy for the pendulum (some is used as heat and deformation energy) , the momentum of the system is conserved. In the case of a pendulum total mechanical energy is conserved. Is ballistic pendulum accurate? Ballistic […]
Is the Grand Canyon a result of the flood?
Is the Grand Canyon a result of the flood? On sale since last summer, “Grand Canyon: A Different View,” by veteran Colorado River guide Tom Vail, asserts the Grand Canyon was formed by the biblical flood that Noah’s ark survived, and can be no more than a few thousand years old. Does the Grand Canyon […]
What did John Locke mean by social contract?
What did John Locke mean by social contract? John Locke’s version of social contract theory is striking in saying that the only right people give up in order to enter into civil society and its benefits is the right to punish other people for violating rights. No other rights are given up, only the right […]
Where are land breezes the strongest?
Where are land breezes the strongest? Land breezes are strongest along the immediate coastline but weaken considerably further inland. Land-breeze circulations can occur at any time of year, but are most common during the fall and winter seasons when water temperatures are still fairly warm and nights are cool. What breeze blows from land to […]
What is Gaussian surface and its importance?
What is Gaussian surface and its importance? Gaussian surface is a closed surface in three dimensional space through which the flux of a vector field is calculated; usually the gravitational field, the electric field, or magnetic field. The concept of Gaussian surface helps in evaluatig the electric field intensity due to symmetric charge distribution. What […]
What are the two types of reflection class 8?
What are the two types of reflection class 8? 4.1 Regular Reflection. 4.2 Diffuse reflection or irregular reflection. What is the best reflective model? Gibbs’ Reflective Cycle. One of the most famous cyclical models of reflection leading you through six stages exploring an experience: description, feelings, evaluation, analysis, conclusion and action plan. What are the […]
How are atoms linked?
How are atoms linked? Molecule is the general term used to describe any atoms that are connected by chemical bonds. There are two main types of chemical bonds that hold atoms together: covalent and ionic/electrovalent bonds. Atoms that share electrons in a chemical bond have covalent bonds. What are three parts of an atom? Our […]
What is the best F ratio for astrophotography?
What is the best F ratio for astrophotography? Fast f/4 to f/5 focal ratios are generally best for lower power wide field observing and deep space photography. Slow f/11 to f/15 focal ratios are usually better suited to higher power lunar, planetary, and binary star observing and high power photography. Medium f/6 to f/10 focal […]
How does a motor operate?
How does a motor operate? Electric motors work by converting electrical energy to mechanical energy in order to create motion. Force is generated within the motor through the interaction between a magnetic field and winding alternating (AC) or direct (DC) current. How do I select a motor for an application? 5 steps to choose the […]
