Answer:
Charge = 4.9096 x 10⁻⁷ C
Explanation:
First, we find the resistance of the copper wire.
R = ρL/A
where,
R = resistance = ?
ρ = resistivity of copper = 1.69 x 10⁻⁸ Ω.m
L = Length of wire = 2.16 cm = 0.0216 m
A = Cross-sectional area of wire = πr² = π(0.00233 m)² = 1.7 x 10⁻⁵ m²
Therefore,
R = (1.69 x 10⁻⁸ Ω.m)(0.0216 m)/(1.7 x 10⁻⁵ m²)
R = 2.14 x 10⁻⁵ Ω
Now, we find the current from Ohm's Law:
V =IR
I = V/R
I = 3.27 x 10⁻⁹ V/2.14 x 10⁻⁵ Ω
I = 1.52 x 10⁻⁴ A
Now, for the charge:
I = Charge/Time
Charge = (I)(Time)
Charge = (1.52 x 10⁻⁴ A)(3.23 x 10⁻³ s)
<u>Charge = 4.9096 x 10⁻⁷ C</u>
Answer:
Earth's atmosphere is a mixture of nitrogen (79%), oxygen (20%), and a small fraction of carbon dioxide, water vapours and other gases. However, the atmospheres on Venus and Mars mainly consist of carbon dioxide.

coefficient of static friction 
Velocity 
Generally the equation for Conservation of energy is mathematically given by
Answer:
I don't know this for sure, but I think its because they need to be able to sit in their seats without flying in the air.
Explanation:
Using the formula:
w = m x g ....... eq1
here w is weight of the object.
m is mass of the object, and
g is the acceleration of gravity.
mass, m = 14 lbm (given)
acceleration of gravity, g= 32.0 ft/
Now, substituting the values in equation (1):
w = 14lbm x 32.0 ft/ = 448 lbm ft/
since, 1 lbf = 32.174 lbm ft/
so, w = 448 x 
w = 13.924lbf
Hence, the mass of an object is 13.924 lbf.
