Can the velocity of a particle change even if its speed is constant give examples? Give example. Yes. Even though its speed is constant, if it is not traveling in a straight line, the velocity can vary. Can an object have zero velocity but non zero acceleration? Acceleration is the change in velocity, not the […]

What is tertiary motion?
What is tertiary motion? Tertiary motion is sequence motion. It is determined by the specific use oi one or several ofthese transition devices: the cut, the jump cut, the dissolve, the wipe, the fade, and special transitional effects. The cut is an instantaneous change from one image to another. What are the primary motions? For […]
What will happen if a house do not have a vent system?
What will happen if a house do not have a vent system? It can make our homes “sick”, with condensation and mould damaging the walls and fabric of our houses.

How can groundwater erosion be prevented?
How can groundwater erosion be prevented? mulch. Using straw, wood chips, saw dust, or some other material as ground cover can limit the effects of erosion until plants or crops can grow to the point of protecting the soil themselves. Are caves formed by erosion? Corrasional or erosional caves are those that form entirely by […]
What increases effective population size?
What increases effective population size? One of the things that can influence the effective population size is the sex ratio of the breeding animals. We can estimate Ne using information from a population census or pedigree database about the numbers of males (Nm) and females (Nf) that produce offspring in a generation. How does population […]
