At the end of the movie Titanic, Rose lies on a piece of furniture, floating in the ocean, and Jack drowns. A common objection p

julsineya [31]

Answer:

If jack is in the piece of furniture it would submerge.

Explanation:

The piece of furniture would submerge if the weight applied on the furniture is greater than the maximum buoancy force the water can provide.

maximum buoacy force = density of liquid × volume submerged× acceleration due to gravity.

= $1025\times v\times 9.8$

v = area × thickness of pine

$1.5\times 5\times 10^{-2}$

= 0.075 $m^{3}$

therefore buoancy force = 1025×0.075×9.8 N

= 753.375 N

weight of rose alone = 46×9.8 N = 450.8 N

weight of jack alone = 58×9.8 = 568.4 N

weight of pine = density of pine × volume of pine

= 350 × 0.075= 26.25 N

weight of pine + weight of rose = 450.8+26.25=477.05 N

weight of pine + rose + jack = 477.05 + 568.4 = 1045.45 N

therefore if jack is in the piece of furniture it would submerge.

The acceleration of a falling rock that was initially moving 5 m/s, and had a final velocity of 11 m/s after accelerating for 3

yanalaym [24]

Answer:

2 m/s²

Explanation:

Given:

v₀ = 5 m/s

v = 11 m/s

t = 3 s

Find: a

v = at + v₀

11 m/s = a (3 s) + 5 m/s

a = 2 m/s²

Which of these forms of radiation passes most easily through the disk of the milky way?.

Elena-2011 [213]

The milky way disk is the structure through which infrared radiation travels most readily.

<h3>What do infrared rays serve for?</h3>

There are several applications for infrared radiation, including thermal imaging, remote controls, fiber optic cabling, infrared astronomy, even meteorology. The greenhouse effect is caused in part by the fact because water vapor or other greenhouse gases absorb infrared light.

<h3>What types of things emit infrared radiation?</h3>

Definition of infrared radiation It is a type of radiant energy that we perceive as heat but which is invisible to the human eye (sometimes referred to as infrared light). Two of the most notable examples of infrared radiation are the sun and fire.
