Answer:
both are solids, both are somewhat pliable
Answer:
64
Explanation:
Distance traveled in 2 hours = 2 * 40 = 80 m
Distance traveled in 3 hours = 3 * 80 = 240m
Total distance covered = 240 + 80 = 320m
Total time = 2 + 3 =5 h
Hence avg speed = total distance covered / total time taken
= 320/5 = 64mph
When winds move air masses, they carry their weather conditions (heat or cold, dry or moist) from the source region to a new region. When the air mass reaches a new region, it might clash with another air mass that has a different temperature and humidity. This can create a severe storm.
Answer:
1272 pound
Explanation:
From the question given above, the following data were obtained:
Pressure (P) = 38 psi
Area (A) = 12 cm by 18 cm
Force (F) =?
Next, we shall determine the area. This can be obtained as follow:
Area (A) = 12 cm by 18 cm
A = 216 cm²
Next, we shall convert 216 cm² to square inch (in²). This can be obtained as follow:
1 cm² = 0.155 in²
Therefore,
216 cm² = 216 cm² × 0.155 in² / 1 cm
216 cm² = 33.48 in²
Finally, we shall determine the force exerted. This can be obtained as follow:
Pressure (P) = 38 psi = 38 lbf/in²
Area (A) = 33.48 in²
Force (F) =?
P = F/A
38 = F / 33.48
Cross multiply
F = 38 × 33.48
F = 1272 pound
Thus, the force exerted is 1272 pound
