How can extinction affect humans?
How can extinction affect humans? As species disappear, infectious diseases rise in humans and throughout the animal kingdom, so extinctions directly affect our health and chances for survival as a species. The rise in diseases and other pathogens seems to occur when so-called “buffer” species disappear. Is extinction good or bad? Nevertheless, extinctions can have […]
What does the radial velocity method measure?
What does the radial velocity method measure? The radial velocity technique is able to detect planets around low-mass stars, such as M-type (red dwarf) stars. This allows astronomers to determine the inclination of the planet’s orbit, which enables the measurement of the planet’s actual mass. Why is the radial velocity method biased towards high mass […]

Can a body have zero velocity and still acceleration give example?
Can a body have zero velocity and still acceleration give example? Yes, a body with a velocity 0 can still accelerate. The simplest example is a body which is thrown up. At the peak point its velocity becomes 0 but still accelerates due to gravity. How can you have acceleration but no velocity? Since acceleration […]

Can a vector have a negative direction?
Can a vector have a negative direction? Vectors having the same length as a particular vector but in the opposite direction are called negative vectors. The magnitude, or length, of a vector, cannot be negative; it can be either be zero or positive. The negative sign is used here to indicate that the vector has […]
