Answer: 24 N
Explanation: solution attached:
F = ma
= 6.0 kg ( 4.0 m/s²)
= 24 N
Answer:
2500 J
Explanation:
Let's solve the problem using the first law of thermodynamics, which states that
U_f - U_i = Q-W
where
Uf is the final internal energy
Ui is the initial internal energy
Q is the heat absorbed by the system
W is the work done by the system
In this problem, we have:
Ui = 2000 J is the initial internal energy
Q = 1000 J is the heat absorbed by the system
W = 500 J is the work done by the piston
If we substitute numbers into the equation, we find:
U_f =U_i + Q-W=2000 J+1000 J-500 J=2500 J
Hello ............ how are you
The effusion rate is 1.125 cm/sec for ammonia.
How to find effusion rate ?
Effusion rate (r1) HCl = 43.2 cm/min
Molar mass (m2) NH3 =17.04g/mole
Molar mass (m1) HCl =36.46g/mole
- Substitute the molar masses of the gases into Graham's law and solve for the ratio.
firstly convert 43.2 cm/min into cm/sec i.e., 0.72 cm/sec
Then,
0.72/r2 =√17.04/36.46
r2= 1.125 cm/sec
Hence, the rate of diffusion of ammonia is 1.125 times faster than the rate of diffusion of hydrogen chloride.
