Answer:
Step-by-step explanation:
Before we even begin it would be very helpful to draw out a simple layout of the circuit. Then we go ahead and apply kirchoffs second law(sum of voltages around a loop must be zero) on the circuit and we obtain the following differential equation,
where V is the electromotive force applied to the LR series circuit, Ldi/dt is the voltage drop across the inductor and Ri is the voltage drop across the resistor. we can re write the equation as,
Then we first solve for the homogeneous part given by,
we obtain,
This is only the solution to the homogeneous part, The final solution would be given by,
where c is some constant, we added this because the right side of the primary differential equation has a constant term given by V/R. We put this in the main differential equation and obtain the value of c as c=V/R by comparing the constants on both sides.if we put in our initial condition of i(0)=0, we obtain 
, so the overall equation becomes,
where if we just plug in the values given in the question we obtain the answer given below,

Answer:
I think the answer is that Best Market sells strawberries at a higher unit price, and that you would have to pay $5.40 more at that store than the other.
Step-by-step explanation:
If we take a look at the graph, we can see that 1 pound of strawberries is worth 2$. That makes the unit price, or the price of per one unit of the item, 2$ for Fine Foods.
In thd directions, they gave us the equation y = 2.9x for strawberries at Best Market. To find the unit price for Best Market, we would have to substitute x for 1 since x represent pounds, and we're trying to find how much 1 pound costs to find the unit price. It would look like this:
y = 2.9 (1)
y = 2.9
So, the unit price at Best Market would be 2.90$.
Comparing the unit prices, 2.90$ is bigger than &2. So, Best Market sells strawberries at a higher unit price. To find out how much 6 pounds of strawberries at Best Market is, all we have to do is substitute x for 6 in y = 2.9x like so:
y = 2.9 (6)
y = 17.40
So, the price for 6 pounds of strawberries is 17.40$ at Best Market. If we refer to the graph for the cost of 6 pounds at Fine Foods, then we know that 6 pounds of strawberries is 12$. 17.40 - 12 = 5.4. So, you would have to pay $5.40 more for 6 pounds at Best Market than Fine Foods.
Answer:
No.
The most appropriate unit to measure the mesoplankton is centimeter.
The size is 2 cm.
Step-by-step explanation:
Earlier, you found the size of a mesoplankton to be 
meter.
I think that meters are not the most appropriate unit to represent the size of a mesoplankton.
The most appropriate unit to measure the mesoplankton is centimeter.
Now, 1 meter is equivalent to 100 centimeters.
So, the size of the mesoplankton in centimeter units will be 
cm. (Answer)
