Answer:
0 N
Explanation:
Applying,
F = qvBsin∅................. Equation 1
Where F = Force on the charge, q = charge, v = Velocity, B = magnetic charge, ∅ = angle between the velocity and the magnetic field.
From the question,
Given: q = 4.88×10⁻⁶ C, v = 265 m/s, B = 0.0579 T, ∅ = 0°
Substitute these values into equation 1
F = ( 4.88×10⁻⁶)(265)(0.0579)(sin0)
Since sin0° = 0,
Therefore,
F = 0 N

Explanation:
m = Mass of material = 3.3 kg
r = Radius of sphere = 1.25 m
v = Volume of balloon = ![\frac{4}{3}\pi r^3](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3)
M = Molar mass of helium = ![4.0026\times 10^{-3}\ kg/mol](https://tex.z-dn.net/?f=4.0026%5Ctimes%2010%5E%7B-3%7D%5C%20kg%2Fmol)
= Density of surrounding air = ![1.19\ kg/m^3](https://tex.z-dn.net/?f=1.19%5C%20kg%2Fm%5E3)
R = Gas constant = 8.314 J/mol K
T = Temperature = 345 K
Weight of balloon + Weight of helium = Weight of air displaced
![mg+m_{He}g=\rho vg\\\Rightarrow m_{He}=\rho vg-m\\\Rightarrow m_{He}=1.19\times \frac{4}{3}\pi 1.25^3-3.3\\\Rightarrow m_{He}=6.4356\ kg](https://tex.z-dn.net/?f=mg%2Bm_%7BHe%7Dg%3D%5Crho%20vg%5C%5C%5CRightarrow%20m_%7BHe%7D%3D%5Crho%20vg-m%5C%5C%5CRightarrow%20m_%7BHe%7D%3D1.19%5Ctimes%20%5Cfrac%7B4%7D%7B3%7D%5Cpi%201.25%5E3-3.3%5C%5C%5CRightarrow%20m_%7BHe%7D%3D6.4356%5C%20kg)
Mass of helium is 6.4356 kg
Moles of helium
![n=\frac{m}{M}\\\Rightarrow n=\frac{6.4356}{4.0026\times 10^{-3}}\\\Rightarrow n=1607.85489](https://tex.z-dn.net/?f=n%3D%5Cfrac%7Bm%7D%7BM%7D%5C%5C%5CRightarrow%20n%3D%5Cfrac%7B6.4356%7D%7B4.0026%5Ctimes%2010%5E%7B-3%7D%7D%5C%5C%5CRightarrow%20n%3D1607.85489)
Ideal gas law
![P=\frac{nRT}{v}\\\Rightarrow P=\frac{1607.85489\times 8.314\times 345}{\frac{4}{3}\pi 1.25^3}\\\Rightarrow P=563712.04903\ Pa](https://tex.z-dn.net/?f=P%3D%5Cfrac%7BnRT%7D%7Bv%7D%5C%5C%5CRightarrow%20P%3D%5Cfrac%7B1607.85489%5Ctimes%208.314%5Ctimes%20345%7D%7B%5Cfrac%7B4%7D%7B3%7D%5Cpi%201.25%5E3%7D%5C%5C%5CRightarrow%20P%3D563712.04903%5C%20Pa)
The absolute pressure of the Helium gas is 563712.04903 Pa

Answer:
The recipe for a hurricane is a combination of warm, humid wind over tropical waters. The temperature of tropical waters must be at least 80 degrees F for up to 165 feet below the ocean’s surface. As this warm water meets the wind that blows west from Africa across the ocean, it causes the water to vaporize. The water vapor then rises into the atmosphere, where it cools and liquefies.
