<span>6.20 m/s^2
The rocket is being accelerated towards the earth by gravity which has a value of 9.8 m/s^2. Given the total mass of the rocket, the gravitational drag will be
9.8 m/s^2 * 5.00 x 10^5 kg = 4.9 x 10^6 kg m/s^2 = 4.9 x 10^6 N
Add in the atmospheric drag and you get
4.90 x 10^6 N + 4.50 x 10^6 N = 9.4 x 10^6 N
Now subtract that total drag from the thrust available.
1.250 x 10^7 - 9.4 x 10^6 = 12.50 x 10^6 - 9.4 x 10^6 = 3.10 x 10^6 N
So we have an effective thrust of 3.10 x 10^6 N working against a mass of 5.00 x 10^5 kg. We also have N which is (kg m)/s^2 and kg. The unit we wish to end up with is m/s^2 so that indicates we need to divide the thrust by the mass. So
3.10 x 10^6 (kg m)/s^2 / 5.00 x 10^5 kg = 0.62 x 10^1 m/s^2 = 6.2 m/s^2
Since we have only 3 significant figures in our data, the answer is 6.20 m/s^2</span>
<span>Usually, If you drop a 200 gram piece of metal with a temperature of 110 degrees Celsius into 1000 grams of water at 25° Celsius, the statement which would best describe what would occur is the last one : </span><span>The water and the metal's temperatures will reach the same temperature. I choose this one because this is a nice example of how the nature tries to reach the balance. Hope it helps! Regards.</span>
The answer is
2.5 N

Conduction is a method of Heat transfer in solids by mutual vibration of the solid particles. The heat particle of one solid receives the heat, and transfer it to the next solid particle to it. This is as a result of the particles touching each other and by a little vibration of the particles.
A conductor is a material that allows the transfer of heat in this case. It could also allow the transfer of electrical current. Example Iron, Copper.
An insulator is a material that is poor in transfer heat or electric current from one point to another. Example is Wood.
Convection is a method of heat transfer in liquid or air medium, by the actual or bulk movement of the heated medium. E.g transfer of heat from hotter air to cooler air, transfer of heat from hotter region of boiling water to the cooler region which is at the surface.
Density is simply mass per unit volume.
Density = Mass / Volume, It's SI Unit = Kg/m3.
Does density depend on temperature?
This is a bit tricky. For liquids we should say yes, there is appreciable difference in density. For example we know that water has maximum density of 1 g/cm3 at 4 degrees Celsius.
But for solids, the density is not affected much, except at very high temperatures.
So in summary we should say Density is affected by temperature, because we know that the volume of the material would be affected and hence the density is affected likewise.
Sorry, the solution came a little bit late.
