Density = Mass divided by Volume, or d = m/v.
So, replace the m and v with the amounts given:
d = 6/12.
Therefore, d = 0.5.
You haven't described the shape of the orbit.
Fortunately, it doesn't matter.
Average speed = (distance covered) / (time to cover the distance)
= (2.0 x 10⁷ meters) / (1 hour)
= 2.0 x 10⁷ meters/hour
= 5,555 and 5/9 meters/second .
Note that this is the satellite's speed.
Regarding velocity:
Velocity = (displacement) / (time for the displacement)
= 10 meters/hour
= 0.002777... meters/second (rounded)
in the direction from the starting point
to the location after that one hour.
Answer:
Energy cannot be changed from one form to another without a loss of usable energy
Explanation:
Second law of thermodynamics states that the total entropy or the randomness of the system remains constant over time. It also states that the net entropy will remain the same or it will increase.
Entropy of a system is given by heat absorbed divided by temperature. It is given by :
So, the correct option is (A) "Energy cannot be changed from one form to another without a loss of usable energy".
Answer:36
Explanation:To analyze a series-parallel combination circuit, follow these steps: Reduce the original circuit to a single equivalent resistor, re-drawing the circuit in each step of reduction as simple series and simple parallel parts are reduced to single, equivalent resistors. Solve for total resistance.
