Hi!

The correct option would be C.

An external conflict is a predicament where the person has to battle with an outside factor, which may be a force of nature, an animal, another person, the weather etc. External conflict may more often than not involve a physical exertion. This is opposed to internal conflicts where an individual has to struggle against a belief, a notion, or an impulse etc - <em>a conflict with oneself</em>. Such as choosing between two pair of dresses would be an internal conflict, and a brawl, or an argument would be an external conflict.

Option C is hence correct as it involves a physical struggle that requires a young boy to guide the boat back to shore, where the conflict is with a force of nature, i.e a water body.

Option A, B and D all deal with the individual in concern's internal conflicts.

Hope this helps!

Assuming that the cost of 16-gauge steel sheet metal is $25.00 per square meter, what is the ideal radius and height of a cylind

Anton [14]

Answer: Radius = 32.7 cm and height = 65.5 cm

Explanation:

An oil drum must have a volume of 218 liters or 218*1000cm^3 = 218,000 cm^3

The price is per square meter, so if we reduce the surface of the oil drum, we will pay less:

So we want to play with the measures of the oil drum in such a way that the surface is minimized.

Now, first, the volume of the oil drum (a cylinder) is:

V = pi*r^2*h

where pi = 3.14, r is the radius and h is the height.

and the surface is:

S = 2*pi*r^2 + 2*pi*r*h

we know that:

pi*r^2*h = 218,000 cm^3

r^2*h = 218,000cm^3/3.14 = 70,096.5 cm^3

now we can write

h = 70,096.5 cm^3/r^2

now we can replace it in the surface equation:

S = 2*pi*r^2 + 2*pi*r*h

= 6.28*(r^2 + 70,096.5 cm^3/r)

So we want to minimize this, we can derivate it and find the zero:

S' = 6.28(2*r - 70,096.5 cm^3/r^2) = 0

2r = 70,096.5 cm^3/r^2

r^3 = (70,096.5 cm^3)/2

r = ∛( (70,096.5 cm^3)/2 ) = 32.7cm

And then the height is:

h = 70,096.5 cm^3/r^2 = 70,096.5 cm^3/(32.7cm)^2 = 65.5cm

A horse trots 17 miles north and then turns and trots 24 miles at an angle of 40° west of north. Find the resultant displacement

DanielleElmas [232]

Answer:

Resultant displacement = 38.58 miles at an angle of 23.57° north of west.

Explanation:

Let north represent positive y direction and east represent positive x direction. Unit vector along x direction is represented by i and vector along unit vector along y direction is represented by j

Initial displacement = 17 miles north = 17 j miles

Final displacement = 24 miles at an angle of 40° west of north = 24 miles at an angle of 130° to positive x -axis

= (24 cos 130 i + 24 sin 130 j )

= (-15.43 i + 18.36 j ) miles

Total displacement = 17 j + (-15.43 i + 18.36 j) = -15.43 i + 35.36 j

Magnitude of displacement $=\sqrt{(-15.43)^2+35.36^2} =38.58 miles$

Angle to positive x -axis = tan⁻¹(35.36/-15.43) = 113.57°

Resultant displacement = 38.58 miles at an angle of 23.57° west of north.
