Water pollution can affect the economy because with no clean water, people will be forced to buy water bottles impacting their disposable income. In the search for clean water, potential future conflicts may occur because water is a fundamental need to human survival. :)
Answer:
0.695 m
Explanation:
α = angular acceleration of the fan blade = 14.1 rad/s²
a = tangential acceleration at the point concerned = acceleration due to gravity = 9.8 m/s²
r = distance of the point from axis of rotation at which tangential acceleration is same as acceleration due to gravity
We know the relation between
a = r α
Inserting the values
9.8 = 14.1 r
r = 0.695 m

Answer:
P₂ = 375 kPa.
Explanation:
Given that,
Initial volume, V₁ = 3 m³
Initial pressure, P₁ = 150 kPa
Final volume, V₂ = 1.2 m³
We need to find the final pressure.
At constant temperature,
So, the new pressure is 375 kPa.
Given:
altitude, x = 1 mile
speed, v = 560 mi/h
distance from the station, x = 4 mi
Solution:
To find the rate,
Now, from the right angle triangle in fig 1.
Applying pythagoras theorem:
differentiating the above eqn w.r.t 't' :
(1)
Now, putting values in eqn (1):
The rate at which distance from plane to station is increasing is:
