A 150-lb person burns about 2700 Calories to run a marathon. How much energy is burned in kJ?
Alex17521 [72]
The question above is simply asking us to convert the value from calories into kilojoules. Therefore, we need some factor to multiply to be able to convert it to such units. For calories to kJ, the factor would be 4.184.

2700 cal ( 4.184 kJ/cal) = 11296.8 kJ

What is the density of a object whose dimensions are 5.54
Tcecarenko [31]

The object with dimensions 5.54\ cm \times 10.6\ cm \times 199\ cm and with mass 250.6 g will have a density equal to 0.02144\ g/cm^3.

<h3><u>Explanation:</u></h3>

<u>Given:</u>

Dimensions of the object = 5.54\ cm \times 10.6\ cm \times 199\ cm

length = l = 5.54 cm

width = w = 10.6 cm

height = h = 199 cm

Mass of the object = m = 250.6 g

<u>Formula:</u>

The relation between density, mass and volume of any object is given by:

Density = \frac{ Mass }{Volume}

Since volume of an object with length (l), width (w) and height (h) [assuming a rectangular object] can be defined as,

V = l \times w \times h =5.54 \times 10.6 \times 199

Volume = V = 11686.076\ cm^3

Density = Mass / Volume = \frac{250}{11686.076}

Density = 0.02144 g/cm^3

Density of the object is 0.02144 g/cm^3
