Lightning occurs when there is a flow of electric charge (principally electrons) between the ground and a thundercloud. The maxi

V125BC [204]

Answer:

$1.25\times 10^{19}\ electrons$

Explanation:

r = Rate of flow of charge = 20000 C/s

t = Time taken = 100 μS

Charge is given by

$Q=rt\\\Rightarrow Q=20000\times 100\times 10^{-6}\\\Rightarrow Q=2\ C$

The charge that flows between the ground and the cloud in this time is 2 C

Number of electrons is given by

$n_e=\dfrac{Q}{e}\\\Rightarrow n_e=\dfrac{2}{1.6\times 10^{-19}}\\\Rightarrow n_e=1.25\times 10^{19}\ electrons$

The number of electrons is $1.25\times 10^{19}\ electrons$

A 3.30 x 10-2-kg block is resting on a horizontal frictionless surface and is attached to a horizontal spring whose spring const

avanturin [10]

Answer:

0.17547 m

Explanation:

m = Mass of block = $3.3\times 10^{-2}\ kg$

v = Velocity of block = 10.8 m/s

k = Spring constant = 125 N/m

A = Amplitude

The kinetic energy of the system is conserved

$\dfrac{1}{2}mv^2=\dfrac{1}{2}kA^2\\\Rightarrow \\\Rightarrow A=\sqrt{\dfrac{mv^2}{k}}\\\Rightarrow A=\sqrt{\dfrac{3.3\times 10^{-2}\times 10.8^2}{125}}\\\Rightarrow A=0.17547\ m$

The amplitude of the resulting simple harmonic motion is 0.17547 m

How does air resistance affect an object’s speed?

tatuchka [14]

When air resistance acts, acceleration during a fall will be less than g because air resistance affects the motion of the falling objects by slowing it down. Air resistance depends on two important factors - thespeed of the object and its surface area. Increasing the surface area of an object decreases its speed.
