ANSWER:
a. 50.53 km/h
b. 32.53 km/h (in the direction of 25˚ S of E)
c. 4.27 km/h
d. 0 km/h
STEP-BY-STEP EXPLANATION:
a.
We have that the speed is given by the following formula:
We know that the equivalence between minutes and hours is that 60 minutes equals 1 hour, therefore:
b.
The velocity is given by the following formula
c.
The total distance traveled would then be two 16 kilometers, that is 32 km and the time would be 7.5 hours. we replace
d.
Since it starts in the same place that it ends, the displacement is equal to 0, therefore, the velocity is equal to 0 km/h
Answer:
0.39AU = 58344000 [km] or 58.500.000 [km]
Explanation:
This is a problem that consists simply in converting units:
AU = astronomic unit
The standard cell potential helps to determine the oxidative and reductive strength of species. All the species that lie below the Standard Hydrogen Electrode in the standard cell potential table are stong oxidizing agents and are highly electronegative while those that are above the Standard Hydrogen Electrode are either weak oxidants or reducing agents
Viscous force is the force that pushes against something travelling through a fluid. Viscous force is an analogue in fluids(liquids or gases) of the force of friction. It acts opposite to the direction in which the object is moving relative to the fluid.
