A fish swimming in horizental plane has velocity vi=(4j+j)m/s at a point in the ocean when aposition relative with acertain rock is Ri=(10i-4j)m After The Fish Swimms With Constant Acceleration For 20s it isvelocity is Uf=(20i-5j) m/s. A) find The Accelaration Of The Fish
2) If The Fish Maintains This Constant Acceleration Where Is It At T=25s

If 2 moles of co_2 at 2l and 500k are expanded reversibly to 20l, more work can be obtained from an adiabatic process than from an isothermal process. is the above statement true or false?

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e

What’s #16 asking and how do i solve it?
