The work should be at least equivalent to the kinetic energy possessed by the boat and its riders. The formula for kinetic energy is written below:
W = KE
W = 1/2*mv²
W = 1/2*(1,000 kg)(1.3 m/s)²
<em>W = 845 J</em>
Answer:
to much to small
Explanation:
i cant zoom in and i cant see
Answer:
Part a)
Part b)
Explanation:
As we know that capacitor plate is connected across 2.1 V and after charging it is disconnected from the battery
So here we can say that charge on the plates will remain conserved
So we will have
now dielectric is removed between the plates of capacitor
so new potential difference between the plates
Part b)
Now the capacitor plates are again isolated and unknown dielectric is inserted between the plates
So again charge is same so potential difference is given as
Flow. such as running into something or friction
Flow Final Answer
