Answer:
The work required to stretch a spring 12 ft beyond its natural length is 432 ft-lb
Explanation:
The work to stretch a spring is calculated using the formula:
Equation (1)
W = work in ft-lb
k = spring constant in lb/ft
x = spring deformation in ft
we clear k from the equation (1)
Equation (2)
We replace x = 2ft, W = 12 ft-lb in the equation (2)
Calculation of work required to stretch spring 12 ft
We replace k = 6 lb/ft and x = 12ft in the equation (1)
In a series circuit, there's only one path for current, so the current
for each bulb has to go through all of them.
If one bulb stops shining ... either because it burned out, or because
somebody unscrewed it and ran away with it ... then no current can flow
through the place where that bulb used to be, and they ALL go out.
This is the main reason why the lights in your house are NOT in series.
There are a lot of other reasons.
It is imperative that the system-grounded conductors remain buried and is denoted as option D.
<h3>What is a Conductor?</h3>
This is referred as a substance which allows electricity and heat to flow through it and examples include metals.
These conductors have to be buried so as to prevent the risk of contact and electrocution of individuals thereby making it a safe method.

Answer: They create antibodies.
Answer:
Big Dipper, Little Dipper, Cassiopeia, Cepheus
Explanation:
In this region, the above constellations are circumpolar. This means that they appear above the horizon at all times. These are only visible all rear round for people living in Canada and Northern United States.
Circumpolar constellations are constellations that never appear below the horizon when seen from a particular location on planet Earth. Furthermore, these constellations can be seen all year while others are only seen at specific times during the year; thus they are known as seasonal constellations.
Five northern constellations are visible from most locations that are north of the equator. These are Cassiopeia, Cepheus, Draco, Ursa Major, and Ursa Minor.
Note that Ursa Major is often confused with the Big Dipper. While the Little Dipper (which is much fainter) is found in the Ursa Minor constellation. Cassiopeia can be recognized due to its W shape which is quite prominent.
