Answer:

A) 375

Explanation:

Here for compound microscope, overall magnification is given by

M=M_o X M_e

= magnification of objective lens

= magnification of eye piece

D= least distant of distinct vision

D= 25.0cm

=Focal length eye piece

= Focal length of objective

With countercurrent flow, diffusion happened in all regions of the filter. Explain why
jeka94

Answer:

When the blood and the dialysate are flowing in the same direction, as the the dialysate and the blood move away from the region of higher concentration of the urea, to a region distant from the source, the concentration of urea in the blood stream and in the dialysis reach equilibrium and diffusion across the semipermeable membrane stops within the higher filter regions such as II, III, IV or V

However, for counter current flow, as the concentration of the urea in the blood stream becomes increasingly lesser the, it encounters increasingly unadulterated dialysate coming from the dialysate source, such that diffusion takes place in all regions of the filter

A stone is dropped from a height of 49m and simultaneously another ball is thrown upward from the ground with a speed of 40m/s.
Lilit [14]

Answer:

S1 = 1/2 g t^2     distance stone falls in time t

S2 = Vy t - 1/2 g t^2   distance thrown stone rises in time t

H = 49 = S1 + S2 = Vy t

t = 49 / 40 sec   time when stones meet

Check:

Stone 1 falls:      1/2 g t^2 = 1/2 * 9.8 * (49 / 40)^2 = 7.35 m

Stone 2 rises :  40 * (49 / 40) - 1/2 * 9.8 (49 / 40)^2 = 41.65 m
