Suppose we want to sample a finite-duration signal x(0) that occupies 0sist (a) devise a way to use the dft to select a suitable sampling rate fs for signal x(t). hint: consider the characteristics of an oversampled signal's dft spectrum.] (b) test the method you devised in part (a) using the signal x() a). use matlab to compute any needed dfts. what value f, seems reasonable for this signal?

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.

explanation:

i think the answer is a, hope this : )

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
