Answer and Explanation:
curents i = 2.9 A
i ' = 4.4 A
the magnitude (in T.m) of the path integral of B.dl around the window frame = μo * current enclosed
= μo* ( i '- i )
Since from Ampere's law
where μ o = permeability of free space = 4π * 10 ^-7 H / m
plug the values we get the magnitude (in T.m) of the path integral of B.dl = ( 4π*10^-7 ) (2.9+4.4)
= 1.884 * 10^-6 Tm
'G' = "giga..." = billion = 10⁹
'ms' = "millisecond" = 0.001 second
100 Gw = 10¹¹ watts
35 ms = 0.035 second
100 Gw x 35 ms = 10¹¹ watts x 0.035 second = 3.5 x 10⁹ J
= 3.5 G-joules
Compounds are combinations of atoms!

Answer:
a) 30.20 m/s
b) 12.91 m/s
Explanation:
Mass of squirrel = 575 g = m
Drag coefficient = 0.70 = C
Density of air = 1.21 kg/m³ = ρ
frontal surface area = 0.0146 m² = A
Height the squirrel falls = 8.5 m = h
a) Drag force
![F=\frac{1}{2}Av^2C\rho\\\Rightarrow F=\frac{1}{2}0.0146v^2\times 0.7\times 1.21](https://tex.z-dn.net/?f=F%3D%5Cfrac%7B1%7D%7B2%7DAv%5E2C%5Crho%5C%5C%5CRightarrow%20F%3D%5Cfrac%7B1%7D%7B2%7D0.0146v%5E2%5Ctimes%200.7%5Ctimes%201.21)
This force will oppose gravity
![mg=F\\\Rightarrow 0.575\times 9.81=\frac{1}{2}0.0146v^2\times 0.7\times 1.21^2\\\Rightarrow \frac{0.575\times 9.81\times 2}{0.0146\times 0.7\times 1.21}=v^2\\\Rightarrow v=30.20\ m/s](https://tex.z-dn.net/?f=mg%3DF%5C%5C%5CRightarrow%200.575%5Ctimes%209.81%3D%5Cfrac%7B1%7D%7B2%7D0.0146v%5E2%5Ctimes%200.7%5Ctimes%201.21%5E2%5C%5C%5CRightarrow%20%5Cfrac%7B0.575%5Ctimes%209.81%5Ctimes%202%7D%7B0.0146%5Ctimes%200.7%5Ctimes%201.21%7D%3Dv%5E2%5C%5C%5CRightarrow%20v%3D30.20%5C%20m%2Fs)
∴ Terminal velocity is 30.20 m/s
b) Neglecting drag force we get
![mgh=\frac{1}{2}mv^2\\\Rightarrow v=\sqrt{2gh}\\\Rightarrow v=\sqrt{2\times 9.81\times 8.5}\\\Rightarrow v=12.91\ m/s](https://tex.z-dn.net/?f=mgh%3D%5Cfrac%7B1%7D%7B2%7Dmv%5E2%5C%5C%5CRightarrow%20v%3D%5Csqrt%7B2gh%7D%5C%5C%5CRightarrow%20v%3D%5Csqrt%7B2%5Ctimes%209.81%5Ctimes%208.5%7D%5C%5C%5CRightarrow%20v%3D12.91%5C%20m%2Fs)
∴ Velocity of a 56 kg person falling that distance, assuming no drag contribution is 12.91 m/s
Of my knowlaedge, the suns light rays are so intense that they bounce off of other planets and shine on the face of the moon giving us the ability ti see the moon at night.
