He did not apply the fifty newtons of greater force! Ok it says when it needed to have the greater force of fifty the person only put 10N out of the fifty, and left out 40N, that is why it did not work properly.
Answer:
Final volume after applying 880 mmHg pressure = 89.28
Explanation:
Initial volume (V 1)= 100 ml
Initial pressure (P1) =780 mm Hg = 780/780 = 1atm
Final pressure (P2)=880 mm Hg = 880/780 =1.12 atm
Final volume (V2)=?
We know that,
Applying Boyle's law,
P1 V1=P2 V2
1*100=1.12*V2
100=1.12*V2
100/1.12=V2
89.28=V2
V2=89.28 ml
Hope this helps you. Please mark me as a brainlist.
Answer:
52 da
Step-by-step explanation:
Whenever a question asks you, "How long to reach a certain concentration?" or something similar, you must use the appropriate integrated rate law expression.
The i<em>ntegrated rate law for a first-order reaction </em>is
ln([A₀]/[A] ) = kt
Data:
[A]₀ = 750 mg
[A] = 68 mg
t_ ½ = 15 da
Step 1. Calculate the value of the rate constant.
t_½ = ln2/k Multiply each side by k
kt_½ = ln2 Divide each side by t_½
k = ln2/t_½
= ln2/15
= 0.0462 da⁻¹
Step 2. Calculate the time
ln(750/68) = 0.0462t
ln11.0 = 0.0462t
2.40 = 0.0462t Divide each side by 0.0462
t = 52 da
Answer:
Yes
Explanation:
The virtue that tungsten is metal it means that it does conduct electricity. Tungsten does conduct electricity currents quite well, such as when compared to iron and nickel. It is, however, not a good conductor as compared to other metals though it does get the job done.
