Answer:
speed of plane in still air = 252 mph
speed of wind = 42 mph.
Explanation:
Given:
Distance travelled by the small plane = 245
Time taken to fly 245 miles = 1 hour and 10 minutes.
Time taken for return trip = 50 minutes.
To Find:
speed of the wind=?
The speed of the plane in still air=?
Solution:
We Know that
=>
=>
=>
=>210 mph against wind
on way back
=>
=>
=>
=> 294
Now
294 = plane +wind------------------------(1)
210 =plane - wind-------------------------(2)
Solving (1) and (2)
2 plane = 504
plane = 252
plane =
So substituting plane value in eq(2) we get,
210 =252 - wind
wind = 42 mph
Answer:pure water is neutral . Lake water is acidic. Baking soda and soapy water are basic.
Explanation: 7 is neutral. The higher on the ph scale like 1-6 is acidic. The lower on the scale 8-13 is base or alkaline.
Hey there!
We use the Clapeyron equation :
P * V = n * R * T
2.45 * V = 0.500 * 0.0821 * 303
2.45 * V = 12.43815
V = 12.43815 / 2.45
V = 5.07 L
