The bleeder is opened at a caliper and no brake fluid flows out. technician a says that this is normal and that brake fluid should not flow or drip out of an open bleeder valve. technician b says that the vent port in the master cylinder may be blocked.
a) technician a only
b) technician b only
c) both technician a and b
d) neither a nor b

b) Technician B only

Explanation:

For the fact no break fluid flows out Of the bleeder valve when It’s opened, that means there’s a blockage stopping the fluid from flowing off.

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

the results is a decrease in air temperature with an increase of altitude.
