<span>If you stand with your legs together, you aren’t going to be able to balance as easily, and you may well end up in the lap of someone who is sitting down. If you spread your legs apart, however, you will be able to plant your feet and lean into any bumps, thus drastically lowering your chance of falling.</span>
<span>The answer is: 30 ft³ ; or, write as: 30 cubic feet .
</span>________________________________________________________
Explanation:
__________________________________________________
Given:
__________________________________________________
Density = 0.4 fish(es) per cubic foot (or, feet);
__________________________________________________
or, "Density = 0.4 fish / ft³ ;
__________________________________________________
And, given: "12 fish in the tank." ;
__________________________________________________
And Density = (value; in this case, "number of fish" / unit volume);
We are given: Density, "D" = 0.4 fish / 1 ft³
______________________________________________
In our case, our volume is in "cubic ft." ; or, "ft³ ;
_______________________________________________
We want to find the actual volume of the tank (in "cubic feet"; or, " ft³ ");
_________________________________________________
→ (1 ft³ / 0.4 fish) * 12 fish = _____? ft³ ?
→ On the "left-hand side" of the equation; the units of "fish" cancel out to "1"; and we are left with units of "ft³ " ; which is the units for which we wish to solve.
_______________
→ So, so have (1 ft³ * 12) / (0.4) = 12 ft³ / 0.4 = 30 ft³ .
___________________________________________________
<span> → The answer is: 30 ft³ ; or, write as: 30 cubic feet .</span>

Complete Question
A toroidal solenoid has 590 turns, cross-sectional area 6.20 cm^2 , and mean radius 5.00 cm .
Part A. Calculate the coil's self-inductance.
Part B. If the current decreases uniformly from 5.00 A to 2.00 A in 3.00 ms, calculate the self-induced emf in the coil.
Part C. The current is directed from terminal a of the coil to terminal b. Is the direction of the induced emf from a to b or from b to a?
Answer:
Part A
Part B
Part C
From terminal a to terminal b
Explanation:
From the question we are told that
The number of turns is
The cross-sectional area is
The radius is
Generally the coils self -inductance is mathematically represented as
Where is the permeability of free space with value
substituting values
Considering the Part B
Initial current is
Current at time t is
The time taken is
The self-induced emf is mathematically evaluated as
=>
substituting values
The direction of the induced emf is from a to b because according to Lenz's law the induced emf moves in the same direction as the current
Anytime an object applies a force to another object, there is an equal and opposite force back on the original object. This is known as an action-reaction.
