A coil of wire with a current flowing thru it becomes a magnet
Answer: first one is electrochemical
Second one is combustion
Third one is photosynthesis
Fourth one is respiration
Answer:
The final pressure of the gas is 9.94 atm.
Explanation:
Given that,
Weight of argon = 0.16 mol
Initial volume = 70 cm³
Angle = 30°C
Final volume = 400 cm³
We need to calculate the initial pressure of gas
Using equation of ideal gas


Where, P = pressure
R = gas constant
T = temperature
Put the value in the equation



We need to calculate the final temperature
Using relation pressure and volume



Hence, The final pressure of the gas is 9.94 atm.
Answer:

Explanation:
Given data:



Let the distance traveled by the object in the second case be 
In the given problem, work done by the forces are same in both the cases.
Thus,
