Its acceleration is 5m/s2.
The formula for acceleration is Final speed - initial speed/time.
So 40m/s - 25m/s is 15m/s.
15m/s divided by 3s is 5m/s2.
Thus the acceleration is 5m/s2
Thermal conduction happens fastest through a solid.
This is true. I hope this helps! (:

Answer:
E the electric field remains unchanged.
Explanation:
potential difference between the plates of a capacitor
V = Q / C Where Q is charge on the capacitor and C is capacity of capacitor
Here Q is unchanged.
C the capacity has value equal to ε A / d
Here d is distance between plates. when it is halved, capacitance C becomes double.
V = Q /C , When C becomes double V becomes half
E = V/d , E is electric field between plates having separation of d.
When V becomes half and d also becomes half , there is no change in the value of E.
Hence E the electric field remains unchanged.
