Question
There are 4 conceptual multiple choice questions Read each question carefully and indicate your answer clearly your scantron. A baseball bat applies a force of 37 kN to an incoming pitch, resulting in solid line drive, while it is in contact with the bat, the baseball provides a force with a magnitude less than 37 kN. with a magnitude of 37 kN. with a magnitude greater then 37 kN. that can't be predicted with the information given. A fish sits on a scale. The scale sits on a table. The table sits on the floor. The floor exerts a normal force upwards on the table and downward on the scale on all three only the table only on the scale only on the fish A fluid is sandwiched between two plate a, a stationary plate and one which moves with a speed in this scenario a resistive force arises due to the dynamic viscosity of the fluid. if the magnitude of this resistive force given by where mu is the dynamic viscosity, A is the surface area of each plate, v is the relative speed of the plates, y is the distance between the plates, what are the SI units of the dynamic viscosity, mu? M^2/kgs kgm/r^2 kgr/m^2 kg/rm it is unitlessExplanation / Answer
from newtons 3rd law action and reaction are same
option B
-----------------
(2)
the table is in contace with floor the floor exerts normal force on table
option C
------------
(3)
unit of F = kg m s-2
A = m2
v = ms-1
y = m
mue = F*y/(A*v)
unit of mue = kg m s-2 m/(m2 ms-1) = kg /ms
option D
