The work done by Chase in pushing the boulder over the given distance is 414J.
Work done
Work is simply the measure of energy transfer that takes place when an object is pulled or pushed by an external force over a given distance.
It is expressed as;
W = F × d
Where F is force applied d is the displacement.
Given the data in the question;
Mass of boulder m = 210kgForce applied F = 180N = 180kgm/s²Distance covered d = 2.3mWork done W = ?To determine the work done by Chase, we substitute our given values into the expression above.
W = F × d
W = 180kgm/s² × 2.3m
W = 414kgm²/s²
W = 414J
Therefore, the work done by Chase in pushing the boulder over the given distance is 414J.

Building sheep pens : darsh and darpan are fencing off a large rectangular area to build some temporary holding pens. to prep the males, females, and kids, they are separated into three smaller and equal-size pens partitioned within the large rectangle. (i) if 384 ft of fencing is available and the maximum area is desired, what will be the dimensions of the larger, outer rectangle? (ii) what will be the dimensions of the smaller holding pens?
The dimensions of the larger outer rectangle and smaller holding pens are respectively; 96ft x 96ft and 31ft x 96ft
How to maximize Functions?Let the side lengths of the big rectangle be x and y. Thus the area of the big triangle is; A = xy
If the fencing available is 384 ft, then perimeter is 384 ft. Thus;
2x + 2y = 384
y = (384 - 2x)/2
y = 192 - x
Putting 192 - x for y in A gives us;
A = x(192 - x) = 192x - x²
Completing the square to rearrange the equation of A gives us;
A = 9216 - (x - 96)²
If A is to be a maximum, then;
x - 96 = 0
x = 96 ft
y = 192 - 96 = 96 ft
Since we maximised the area of the bigger rectangle , we have maximised the area of the smaller pens. The dimensions of the smaller holding pens will be;
x' = 96 ft /3 = 31 ft
y' = 96 ft

If the concentration of sn2+ in the cathode compartment is 1.30 m and the cell generates an emf of 0.21 v , what is the concentration of pb2+ in the anode compartment?
By the use of the Nernst equation, the concentration of the lead solution is 4.8 * 10^-8 M.
What is Nernst equation?The Nernst equation is the equation that is used to obtain the EMF of a cell under non standard conditions.
Now;
E°cell = -0.01 V
Ecell = 0.21V
[sn2+] = 1.30 M
[pb2+] = ?
From;
Ecell = E°cell - 0.0592/n logQ
The equation is; Sn^+ + Pb ----> Sn(s) + Pb^2+
0.21 = -0.01 - 0.0592/2 log(x/1.30 )
0.21 + 0.01 = -0.0592/2 log(x/1.30 )
0.22/-0.0296 = log(x/1.30 )
-7.43 = log(x/1.30 )
Antilog(-7.43) = x/1.3
x = 4.8 * 10^-8 M

Food chains represent oversimplifications of producer-consumer relationships. indicate if the following statements about interactions among trophic levels are true or false in explaining the complexity of these interactions.
Answer:
The statement "Food chains represent oversimplifications of producer-consumer relationships" is true.
Explanation:
Food chains are linear representations of the flow of energy and nutrients through an ecosystem. They typically involve a single pathway of energy transfer from producers (plants) to primary consumers (herbivores) to secondary consumers (carnivores or omnivores) and so on. However, in reality, ecological interactions are much more complex and interconnected.
In natural ecosystems, food webs are more accurate representations of the trophic interactions. Food webs consist of multiple interconnected food chains, showcasing the various feeding relationships and interactions among different species within an ecosystem. They include multiple producers, consumers at different trophic levels, and decomposers, creating a complex network of energy flow.
Food chains can be useful as simple models to understand basic energy flow patterns, but they do not fully capture the intricacies and complexities of the actual interactions in an ecosystem. In contrast, food webs provide a more comprehensive picture of how energy, nutrients, and interactions are shared and exchanged among species, making them more accurate representations of the relationships in an ecosystem.
Which function is continuous at x = 18? f (x) = startfraction (x minus 18) squared over x endfraction f (x) = startfraction x squared minus 17 x minus 18 over x minus 18 endfraction f (x) = tangent (startfraction pi over 36 endfraction x) f (x) = startlayout enlarged left-brace first row x squared, x not-equals 18 second row 36, x = 18 endlayout
The function that is continuous at x = 18 is:
y = (x - 18)/x
Which function is continuous at x = 18?
We need to see which function has no problems when x = 18.
For example, the first one:
y = (x - 18)/x
When x = 18, we have:
y = (18 - 18)/18 = 0
Then this function is continuous at x = 18.
When, for the second option, we have (x - 18) on the denominator, and then when x = 18 the denominator becomes 0, so that function is not continuous at x = 18.
With that, we conclude that the correct option is the first one.
