Thomson experiment he calculated the charge to mass ratio just be passing the fundamental charge through a tube
He calculated the charge to mass ratio just by finding the deflection of charge while it is passing through the constant electric field
so here we will use the deflection as following
let say it passes the field of length "L"
so here we have

now in the same time if it deflect by some distance


now by solving this equation we can find e/m ratio
so here correct answer will be
the electron's charge-to-mass ratio
Answer
According the conservation of energy

I for ball = 




![v_i^2+[1+\dfrac{2}{3}]=2gh](https://tex.z-dn.net/?f=v_i%5E2%2B%5B1%2B%5Cdfrac%7B2%7D%7B3%7D%5D%3D2gh)



a) 


b) 


Answer:
number 1 is b number 2 is c number 3 is b
The oceanic crust solidifies faster than the continental crust. Because when magma comes into contact with ocean water it cools faster than when it reaches continental rock. Option C is correct.
<h3>What is the crust?</h3>
The outermost layer of a terrestrial planet is referred to as its "crust."
In the upper mantle, the Earth's crust is constantly melting and solidifying. Compared to magma beneath the continental crust, the oceanic crust has a lower temperature.
Magma cools more quickly when it comes into touch with ocean water than when it hits continental rock. causes the continental crust to solidify more slowly than the oceanic crust.
Hence option C is correct.
