Correct answer only please. I will upvote.
The velocity of a particle moves along the x-axis and is given by the equation ds/dt = 40 - 3t^2 m/s. Calculate the acceleration at time t=2 s and t=4 s. Calculate also the total displacement at the given interval. Assume at t=0 s=5m.Write the solution using pen and draw the graph if needed.
I want the steps of operation of the circuit, clearly in
detail. Please.

Heat transfer
Given data:
a= 10 cm.
L= 10 cm.
b= 20 cm.
H=40cm.
⚫ a = 10, cm: This could represent the width of the duct.
⚫b=20, cm: This might be the height of the duct.
⚫L = 10, cm: This usually stands for the length of the duct in
the direction of flow.
⚫H=40, cm: This could indicate the height of some
component or another duct-related dimension, but the exact
meaning depends on the experiment's context.
