How many ternary strings of length 2 n are there in which the zeroes appear only in odd-numbered positions?

Which type of microscope would allow the viewer to see ribosomes inside a cell?

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )
