Answer:
Sub stratul exterior lichid-metal al miezului Pământului se află o bilă solidă de fier și aliaj de nichel cu aproximativ 1,60 km în diametru.
Explanation:
Answer: Hence, the final temperature is 350 K
Explanation :
To calculate the final temperature of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
![\frac{P_1}{T_1}=\frac{P_2}{T_2}](https://tex.z-dn.net/?f=%5Cfrac%7BP_1%7D%7BT_1%7D%3D%5Cfrac%7BP_2%7D%7BT_2%7D)
where,
are the initial pressure and temperature of the gas.
are the final pressure and temperature of the gas.
We are given:
![P_1=880mmHg\\T_1=20^0C=(20+273)K=293K\\P_2=1050mmHg\\T_2=?](https://tex.z-dn.net/?f=P_1%3D880mmHg%5C%5CT_1%3D20%5E0C%3D%2820%2B273%29K%3D293K%5C%5CP_2%3D1050mmHg%5C%5CT_2%3D%3F)
Putting values in above equation, we get:
![\frac{880mmHg}{293K}=\frac{1050mmHg}{T_2}\\\\T_2=350K](https://tex.z-dn.net/?f=%5Cfrac%7B880mmHg%7D%7B293K%7D%3D%5Cfrac%7B1050mmHg%7D%7BT_2%7D%5C%5C%5C%5CT_2%3D350K)
Hence, the final temperature is 350 K
Answer:
Both the astronauts and photographer have the same displacement
Explanation:
Displacement is the minimum distance between two point. The initial point of both the astronauts and the photographer was Florida and the final point was California. So, the minimum distance for both of the astronauts and the photographer would be the distance between Florida and California would be the same.
Hence, both the astronauts and photographer will have the same displacement.
Relative motion means a motion relative to a reference point. We can also say, relative motion means motion referred or observed from a reference point.
For example, Alex is in a train and Ace is at the station, when the train starts moving, for Ace it is moving at a speed of 10 m/s, but for Alex it is moving at 0 m/s, or we can say that it is at rest for Alex, but in motion for Ace. This is relative motion.
I think it’s, its direction would reinforce the original movement
