You should be particularly careful a restraining a struggling rabbit because it can

Shtirlitz [24]

You have no options here so I'll just answer. It can cause a rise in heart rate and greatly increases the risk of overheating and even death. If you grab the rabbit too hard, you risk breaking/fracturing a bone or causing other kinds of damage, whether externally or internally, to the rabbit.

An electron is released from rest at the negative plate of a parallel plate capacitor. The charge per unit area on each plate is

dmitriy555 [2]

Answer:

v = 1.15*10^{7} m/s

Explanation:

given data:

charge/ unit area $= \sigma = 1.99*10^{-7} C/m^2$

plate seperation = 1.69*10^{-2} m

we know that

electric field btwn the plates is $E = \frac{\sigma}{\epsilon}$

force acting on charge is F = q E

Work done by charge q id $\Delta X =\frac{ q\sigma \Delta x}{\epsilon}$

this work done is converted into kinectic enerrgy

$\frac{1}{2}mv^2 =\frac{ q\sigma \Delta x}{\epsilon}$

solving for v

$v = \sqrt{\frac{2q\Delta x}{\epsilon m}$

$\epsilon = 8.85*10^{-12} Nm2/C2$

$v = \sqrt{\frac{2 1.6*10^{-19}1.99*10^{-7}*1.69*10^{-2}}{8.85*10^{-12} *9.1*10^{-31}}$

v = 1.15*10^{7} m/s

a wave travels at a speed of 793 m/s and has a wavelength of 2.3 meters. calculate the frequency of the wave

Savatey [412]

Answer:

344.8 Hz

Explanation:

The frequency of a wave is given by:

$f=\frac{v}{\lambda}$

where

v is the speed of the wave

$\lambda$ is its wavelength

Here we have

v = 793 m/s

$\lambda=2.3 m$

Substituting into the equation, we find

$f=\frac{793 m/s}{2.3 m}=344.8 Hz$
