In fig. 5-36, let the mass of the block be 8.5 kg and the angle θ be 30°. find (a) the tension in the cord and (b) the normal force acting on the block. (c) if the cord is cut, find the magnitude of the resulting acceleration of the block.

i just want to know why you use sin to find the tension and not cos

Which of the following represents a function? 50 !

1. why is a frequency distribution useful? it allows researchers to see the "shape" of the data. it tells researchers how often the mean occurs in a set of data. it can visually identify the mean. it ignores outliers. 2. the is defined by its mean and standard deviation alone. normal distribution frequency distribution median distribution marginal distribution 3. approximately % of the data in a given sample falls within three standard deviations of the mean if it is normally distributed. 95 68 34 99 4. a data set is said to be if the mean of the data is greater than the median of the data. normally distributed frequency distributed right-skewed left-skewed
