Answer:
The volume will not contract to one fourth of the original.
Explanation:
Applying Charles's Law as:

Given ,
V₁ = ?
V₂ = 2 L
T₁ = 5 °C
T₂ = 20 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (5 + 273.15) K = 278.15 K
T₂ = (20 + 273.15) K = 293.15 K
Using Charles law as:



Thus, the volume will not contract to one fourth of the original. (1/4 of 2 L is 0.5 L).
Answer:
(a) 
(b) 
Explanation:
Given data
Distance r₁=50 m
Distance r₂=2 m
Intensity I₂=2.0 W/m²
To find
(a) The Sound Intensity I₁
(b) The Sound Intensity level β
Solution
For (a) the Sound Intensity I₁

For (b) the Sound Intensity level β
The Sound Intensity level β is calculated as follow

The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.
I’m not sure but when’s the deadline
