Answer:
57330.17766 Pa
Explanation:
= Pressure at 4000 m = 61660 Pa
= Density at 4000 m = 0.8194 kg/m³
(Values taken from table of properties of air)
= Velocity of jet =
= Velocity at max thickness
From Bernoulli's equation
The absolute pressure at this point on the wing is 57330.17766 Pa
Answer:
Let's see the similarities between the two forces
* are proportional to the product of a magnitude, mass or charge
* They are inversely proportional to the square of the distance
* They are long-range forces since zero is not made up to an infinite distance. The gravitational force is always attractive, the electrical force can be attractive or repulsive.
The differences in them
* The electric force in much greater than the gravitational force
* The gravitational force is always attractive, the electrical force can be attractive or repulsive.
Explanation:
Let's start by calculating each force.
Gravitational force
F =
let's calculate
F = 6.67 10⁻¹¹ 1 1 / 1²
F = 6.67 10⁻¹¹ N
Electric force
F =
indicates that the charge is q = 10 C
F = 9 10⁹ 10 10 / 1²
F = 9 10¹¹ N
