Down stream it would be going 20 mph and up stream 10 mph
Answer: no
Explanation:
because the object is moving downwards so it will be called decceleration . which is the opposite of acceleration .
Density offers a convenient means of obtaining the mass of a body from its volume or vice versa; the mass is equal to the volume multiplied by the density (M = Vd), while the volume is equal to the mass divided by the density (V = M/d).
M = V d
M = 1.4 * 2 = 2.8 kg
C. 4 N is the answer if not then i be dumb!!!
