A small plastic bead has been charged to -15nC.
marishachu [46]

Answer:

Explanation:

q = - 15 n C = - 15 x 10^-9 c

(a) d = 0.9 cm = 0.009 m

electric field on proton, E = Kq/d²

E = 9 x 10^9 x 15 x 10^-9 / (0.009)²

E = 1.67 x 10^6 N/C

Force on proton, F = charge on proton x Electric field

F = 1.6 x 10^-19 x 1.67 x 10^6 = 2.67 x 10^-13 N

acceleration of proton, a = F / m

a = (2.67 x 10^-13) / (1.67 x 10^-27)

a = 1.6 x 10^14 m/s²

(B) the direction of acceleration is towards the bead, as the force is attractive.

(C) d = 0.9 cm = 0.009 m

electric field on proton, E = Kq/d²

E = 9 x 10^9 x 15 x 10^-9 / (0.009)²

E = 1.67 x 10^6 N/C

Force on electron, F = charge on electron x Electric field

F = 1.6 x 10^-19 x 1.67 x 10^6 = 2.67 x 10^-13 N

acceleration of proton, a = F / m

a = (2.67 x 10^-13) / (9.1 x 10^-31)

a = 3 x 10^17 m/s²

(D) the direction of acceleration is away from the bead, as the force is repulsive.

What kind of fluctuations in weather patterns do you expect to see in your area? Will the fluctuations or changes vary by month,
balandron [24]
Prevailing definitions of climate are not much different from “the climate is what you expect, the weather is what you get”. Using a variety of sources including reanalyses and paleo data, and aided by notions and analysis techniques from Nonlinear Geophysics, we argue that this dictum is fundamentally wrong. <span>In addition to the weather and climate, there is a qualitatively distinct intermediate regime extending over a factor of ≈ 1000 in scale.Climate changes is projected to affect individual organisms, populations, ... Overall, there is a strong correlation between topographic slope and velocity from ... the ecosystems they live in—will adapt to these changes, or if they even can.</span>

An astronaut has become detached from her spaceship. She's floating in space holding a wrench. She's 50 m from her current locat
egoroff_w [7]

Answer:

She throws the wrench in the opposite direction of her destination and the resulting backward force should be enough to get her back to the station.

Is it possible to create a visual model (stop motion) of a wave motion using the differential equation for simple harmonic oscil
Alexeev081 [22]

Answer:

  • Yes.

Explanation:

A particular solution for the 1D wave equation has the form

\Psi(x,t) \ = \ A \ sin ( \ k x \ + \omega t \ + \phi \ )

where A its the amplitude, k the wavenumber, ω the angular frequency and φ the phase angle.

Now, for any given position x_0, we can use:

\phi_0 \ = \ \phi \ + \ k x_0

so, the equation its:

\Psi(x_0,t) \ = \ A \ sin ( \omega t \ + \ \phi_0 ).

This is the equation for a simple harmonic oscillation!

So, for any given point, we can use a simple harmonic oscillation as visual model. Now, when we move a \delta distance from the original position, we got:

x_1 = x_0 + \delta

and

\phi_1 = \phi  \ + k x_1

now, this its

\phi_1 = \phi  \ + k ( x_0 + \delta)

\phi_1 = \phi  \ + k  x_0 + k \delta

\phi_1 = \phi_0 + k \delta

So, there its a phase angle difference of k \delta. We can model this simply by starting the simple harmonic oscillation with a different phase angle.

What is the si unit of power?
grandymaker [24]
The SI unit of power is the watt<span>, which is equal to one </span>joule/<span>per second.

So I would say Watt is the answer. Hope it helped. :)
