To not die in a helicopter crash
Answer:
v/U=0.79
Explanation:
Given u=
Now for the given flow to be possible it should satisfy continuity equation
Applying values in this equation we have
Thus we have
Hence proved
For maximum value of v/U put y =
Thus solving we get using the given values
v/U=0.79
Answer:
I think the answer is electric potential.
Answer:
170 N
Explanation:
The following data were obtained from the question:
Mass (m) = 20 Kg
Angle (θ) = 30°
Acceleration due to gravity (g) = 9.8 m/s²
Weight (W) =?
The perpendicular component of the weight can be obtained by using the following formula:
W = mg × Cosθ
W = 20 × 9.8 × Cos 30
W = 196 × 0.866
W = 169.7 ≈ 170 N
Therefore, perpendicular component of the weight is 170 N
Answer:
False
Explanation:
It is a vector because of the acceleration being a vector. F=ma.
