I think the answer to this question is letter A(I think)
Answer:
A) The greater the variance within the population, the larger the sample should be.
Explanation:
The variance of a sample mean is inversely proportional to the sample size, that is, the larger the sample size the smaller the variability of the sample. When sample size increases, the range decreases and hence the variance decreases resulting in a more accurate research result with minimal experimental error.
Hence the researcher should employ a large sample size to reduce the variation in the population.
Answer:
ITS B
Explanation:
The direction of velocity is perpendicular to the direction of the position and tangent to the circular orbit. Direction of velocity is constantly changing. When an object moves in a circular orbit, the direction of the velocity changes and the speed may change as well.
The direction of velocity changes at every point in a circular motion. The tangent at any point gives the direction of velocity at that point, where as acceleration is always directed towards the recent in a uniform circular motion.
Most of the time it would be beachhead, but it can also be drop-offs, cliffs, etc
hope this helps
