Answer:
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].
Answer:
well, it increased by 40 km/hr in 9 s, so the acceleration is
40/9 km/(hr-s)
Explanation:
<u>Answer:</u> The volume of oxygen gas required is 3.75 mL
<u>Explanation:</u>
STP conditions:
1 mole of a gas occupies 22.4 L of volume.
We are given:
Volume of ammonia reacted = 3.00 mL = 0.003 L (Conversion factor: 1 L = 1000 mL)
The chemical equation for the reaction of ammonia with oxygen follows:

By Stoichiometry of the reaction:
(4 × 22.4) L of ammonia reacts with (5 × 22.4) L of oxygen gas
So, 0.003 L of ammonia will react with =
of oxygen gas
Hence, the volume of oxygen gas required is 3.75 mL
The one with the smaller mass because they have the same force but one is lighter
