A445n student eats 50g of pringles. they feel guilty and decide to climb up some stairs to make up for it. how many flights of stairs would they have to climb to burn off the added energy?

808

Step-by-step explanation:

One serving of Original Pringles = 28 g           = 150 Cal  

Pringles  ⟶ Cal     50 g × (150 Cal/28 g)          = 268 Cal

Cal ⟶ J                  268 Cal × (4184 J/1 Cal)      = 1.121 × 10⁶ J

J ⟶ N·m                 1.121 × 10⁶ J × (1 N·m/1 J)      = 1.121 × 10⁶ N·m

N·m ⟶ m                1.126 × 10⁶ N·m/455N         = 2460 m

m ⟶ km                 2460 m × (1 km/1000 m)     = 2.46 km

km ⟶ mi                2.46 km × (0.6214 mi/1 km) = 1.53 mi

mi ⟶ ft                   1.53 mi ×(5280 ft/1 mi)         = 8080 ft

ft ⟶ flights             8080 ft × (1 flight/10 ft)        = 808 flights

The student would have to climb 808 flights of stairs to burn off the energy from 50 g of Pringles [that's equivalent to climbing the stairs in the Salesforce Tower (1070 ft) in San Francisco about 7½ times].

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
