Answer:
D) 19.8 lbs
Explanation:
1kg in household measurement is equal to 35.274 ounces. 35.274*9=317.466 ounces.
1kg is also equal to 2.205 lbs. 9*2.205=19.8416
9 kg is also equal to 9000 grams, but grams are not a part of the household measurement system
a) 9000 grams. b) 9000 ounces. c) 19.8 ounces. d) 19.8 pounds.
This leaves us with 19.8 lbs
Answer: 981 Pa
Explanation:
1) Data:
m = 60 kg
S = 6000 cm²
P = ?
2) Formulas
i) F = peso = mg
ii) P = F / S
3) Solution
i) F = 60kg × 9.81 m/s² = 588.6 N
ii) P = F / S
First, convert 6000 cm² to m²: 6000 cm² × 1m² / (100cm)² = 0.6 m²
Now, plug in the values and do the operations: P = 588.6N / 0.6m² = 981 Pa
Answer:
mantle convection is the very slow creeping motion of earths solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface.
A meteor is the flash of light that we see in the night sky when a small chunk of interplanetary debris burns up as it passes through our atmosphere. "Meteor" refers to the flash of light caused by the debris, not the debris itself.
