<u>#{1} liquid</u>
<u>#{2} gas </u>
Explanation:
as we know that there are mainly three states of substance
but among them only two of them can fluid and takes the shape of the container that are liquid and gas
Answer:
475 m , 950 m
Explanation:
Let l be the length of the side perpendicular to the barn.
1900-2l = length of the side parallel to the barn
Area A= l( 1900-2l)
A= 1900l-2l^2
now, the maximum value of l ( the equation being quadratic)
l_max= -b/2a
a= 2
b=1900
l_max= -1900/4= 475 m
then 1900-2l= 1900-2×(475) = 950 m
So, the dimensions that maximize area are
950 and 475
Now. A_max = -2( l_max)^2+1900×l_max
A_max= -2(475)^2+1900×475
A_max= 451250 m^2
or, 475×950 = 451250 m^2
Answer:
11.962337 × 10^-4 N
Explanation:
Given the following :
Length L = 11.8
Charge = 29nC = 29 × 10^-9 C
Linear charge density λ = 1.4 × 10^-7 C/m
Radius (r) = 2cm = 2/100 = 0.02 m
Using the relation:
E = 2kλ/r ; F =qE
F = 2kλq/L × ∫dr/r
F = 2*k*q*λ/L × (In(0.02 + L) - In(0.02))
2*k*q*λ/L = [2 × (9 * 10^9) * (29 * 10^9) * (1.4 * 10^-7)]/ 0.118] = 6193.2203 × 10^(9 - 9 - 7) = 6193.2203 × 10^-7 = 6.1932203 × 10^-4
In(0.02 + 0.118) - In(0.02) = In(0.138) - In(0.02) = 1.9315214
Hence,
(6.1932203 × 10^-4) × 1.9315214 = 11.962337 × 10^-4 N
