Answer:

Explanation:
By an adequate application of the Principle of Energy Conservation, the escalator need energy to elevate from to the bottom to the top. Hence:

An expression for power needed is found by deriving the equation with respect to time:

The minimum power is found by substituting known inputs:


Answer:
A computer programmer, sometimes called a software developer, a programmer or more recently a coder (especially in more informal contexts), is a person who creates computer software.
Answer:
Answer explained below
Explanation:
The value of here is 9
The value of there is hexadecimal value of DECO here, d = 0x39 aaaa (aaaa is the memory address of here )
We have the object code :-
let's take there address is 0x0007
0x0005 BR there :- 0x120020
0x0007 here: .WORD 9
310003 there: DECO here,d - 0x390007
310005 STOP
.END

Explanation:
Given that;
A fluid flows along the x axis with a velocity given by V = (xt) i ˆ, where x is in feet and t in seconds. (a) Plot the speed for 0 ≤ x ≤ 10 ft and t = 3 s. (b) Plot the speed for x = 7 ft and 2 ≤ t ≤ 4 s. (c) Determine the local and convective acceleration. (d) Show that the acceleration of any fluid particle in the flow is zero. (e) Explain physically how the velocity of a particle in this unsteady flow remains constant throughout its motion.
