A theory is an idea that is widely agreed on by scientists and can be changed when new info comes to light while a hypothesis is an educated guess sometimes based on prior knowledge.
Answer: 3.12 * 10^12 F ( 3.12 pF)
Explanation: To calculate this capacitor of two hollow, coaxial, iron cylinders, we have to determine the potental differente between them and afeter that to use C=Q/ΔV
The electric field in th eregion rinner<r<router
By using the Gaussian law
∫E*ds=Q inside/εo
E*2*π*rinner^2*L= Q /εo
E=Q/(2*π*εo*r^2)
[Vab]=\int\limits^a_b {E} \, dr
where a and b are the inner and outer radii.
Then we have:
ΔV= 2*k*(Q/L)* ln (b/a)
replacing the values and using that C=Q/ΔV
we have:
C= L/(2*k*ln(b/a)=0.17/(2*9*10^9*3.023)=3.12 pF
Answer:
313.6 m
Explanation:
From the question given above, the following data were obtained:
Time (t) = 8 s
Acceleration due to gravity (g) = 9.8 m/s²
Height (h) =?
The height at which the package was dropped can be obtained as follow:
h = ½gt²
h = ½ × 9.8 × 8²
h = 4.9 × 64
h = 313.6 m
Thus, the package was at a height of 313.6 m when it was dropped.
The theoretic volume and pressure of a gas at zero Kelvin are zero. Moreover, there is zero kinetic energy present in the gas. This is because at zero Kelvin, none of the particles are moving.
