Answer:
The pressure at this point is 0.875 mPa
Explanation:
Given that,
Flow energy = 124 L/min
Boundary to system P= 108.5 kJ/min
We need to calculate the pressure at this point
Using formula of pressure
Here,
Where, v = velocity
Put the value into the formula
Hence, The pressure at this point is 0.875 mPa
C. Force causes displacement
Pressure = F/A
Where,
F = Force exerted = 150 N
A = Area = 1*0.5 = 0.5 m^2
Therefore,
Pressure exerted by wind on the wind = 150/0.5 = 300 N/m^2
1 N/m^2 = 1 Pa,
Then,
Pressure, P = 300 Pa
Efficiency of heat engine is determined by the ratio of difference in temperature of cold from hot reservoir to the temperature of hot reservoir over temperature of hot reservoir.
Answer:
Lets take
u =velocity
θ =angle from horizontal
The horizontal component of velocity = u cosθ
The vertical component of velocity = u sinθ
The horizontal distance x in time t
x = u cosθ .t -----------1
The vertical distance y in time t
--------2
t= x/(u cosθ) ( tanθ=sinθ/cosθ)
Form above we can say that path of the projectile motion is parabolic.
