Air is a better conductor when the humidity is high. 

That's why you cannot zap your sister on a humid or rainy day,
even after scuffing your feet on the carpet.  The charge that you
build up from the carpet quickly flows away from you through the air.

skateboarder, starting from rest, rolls down a 13.5 m ramp. When she arrives at the bottom of the ramp her speed is 7.37 m/s. If
scZoUnD [109]

Answer:

1.7 m/s²

Explanation:

d = length of the ramp = 13.5 m

v₀ = initial speed of the skateboarder = 0 m/s

v = final speed of the skateboarder = 7.37 m/s

a = acceleration

Using the equation

v² = v₀² + 2 a d

7.37² = 0² + 2 a (13.5)

a = 2.01 m/s²

θ = angle of the incline relative to ground = 29.9

a' = Component of acceleration parallel to the ground

Component of acceleration parallel to the ground is given as

a' = a Cosθ

a' = 2.01 Cos29.9

a' = 1.7 m/s²

In the process of peppering the question with those forty (40 !) un-necessary quotation marks, you neglected to actually show us the illustration.  So we have no information to describe the adjacent positions, and we're not able to come up with any answer to the question.

A charged cloud system produces an electric field in the air near earth's surface. a particle of charge -2.0 × 10-9 c is acted o
defon

Part a)

Magnitude of electric field is given by force per unit charge

E = \frac{F}{q}

E = \frac{4.3 * 10^{-6}}{2 * 10^{-9}}

E = 2150 N/C

Part b)

Electrostatic force on the proton is given as

F = qE

F = 1.6 * 10^{-19} * 2150

F = 3.44 * 10^{-16} N

PART C)

Gravitational force is given by

F_g = mg

F_g = 1.6 * 10^{-27}*9.8

F_g = 1.57 * 10^{-26} N

PART d)

Ratio of electric force to weight

\frac{F_e}{F_g} = \frac{3.44 * 10^{-16}}{1.57*10^{-26}}

\frac{F_e}{F_g} = 2.2 * 10^{10}
