The first one is decreases because there are less molecules in the air.
The second on would be the last option, August 29, because a new moon occurs every 29 days.
The answer for the last one would be A, I presume, because when air masses arrive at a destination, it becomes dry.
Answer:
Replication
Explanation:
<em>The process of running multiple trials for each measurement during an experiment and finding the average is referred to as </em><em>replication.</em>
Replication is one of the attributes of good measurements/experiments because it reduces variability and increases the accuracy of the outcome. It also ensures that relevant statistical analysis can be carried out on the data collected via replicative measurements.
Answer:
sir Isaac Newton is referred as the father of modern physics
At a point on the streamline, Bernoulli's equation is
p/ρ + v²/(2g) = constant
where
p = pressure
v = velocity
ρ = density of air, 0.075 lb/ft³ (standard conditions)
g = 32 ft/s²
Point 1:
p₁ = 2.0 lb/in² = 2*144 = 288 lb/ft²
v₁ = 150 ft/s
Point 2 (stagnation):
At the stagnation point, the velocity is zero.
The density remains constant.
Let p₂ = pressure at the stagnation point.
Then,
p₂ = ρ(p₁/ρ + v₁²/(2g))
p₂ = (288 lb/ft²) + [(0.075 lb/ft³)*(150 ft/s)²]/[2*(32 ft/s²)
= 314.37 lb/ft²
= 314.37/144 = 2.18 lb/in²
Answer: 2.2 psi
Answer:
b) 105220.8 m
c) 65.38 miles
d) Kenneth's home
Explanation:
Velocity of Sarah = 31 m/s east
Velocity of Kenneth = 65 mph = 65×(1609.34/3600) m/s west
Time in seconds = 29.2×60 = 1752 s
Displacement = Velocity × time
Displacement of Sarah = 31×1752 = 54312 m
Displacement of Kenneth = 65×(1609.34/3600)×1752 = 50908.8 m
b) So, distance between their homes in meters is 54312 m + 50908.8 m = 105220.8 m
c) Converting to miles
Their homes are 65.38 miles apart
d) They met closer to Kenneth's house (50908.8 m)
