Answer: 9/4n
Explanation:
Let's take T to represent tank
When n litres of fuel was added to tank that was 1/3 full = n + 1/3T
The tank was 7/9T
n+1/3T = 7/9T
n =7/9T - 1/3T
n = 4/9
If a full tank is taken to be 1 = 9/9
Hence, we will have 1 = x × n
1 = x × 4/9
x = 9/4
Hence 9/4 of n = 9/4n
Answer:
D

Rinse the cuvette with the sample solution, after washing, to remove residual solvent.
Answer:So, the difference between charging by induction and conduction comes down to the contact of the neutral object and the object used to charge it. Conduction requires direct contact, while induction does not.
Explanation:
Answer
given,
high temperature reservoir (T_c)= 464 K
efficiency of reservoir (ε)= 25 %
temperature to decrease = ?
increase in efficiency = 42 %
now, using equation




T_C = 348 K
now,
if the efficiency is equal to 42$ = 0.42
