Answer:
The gravitational force on the elevator = 4500N
Explanation:
The given parameters are;
The force applied by the elevator, F = 4500 N
The acceleration of the elevator = Not accelerating
From Newton's third law of motion, the action of the cable force is equal to the reaction of the gravitational force on the elevator which is the weight, W and motion of the elevator as follows;
F = W + Mass of elevator × Acceleration of elevator
∴ F = W + Mass of elevator × 0 = W
F = 4500 N = W
The net force on the elevator is F - W = 0
The gravitational force on the elevator = W = 4500N.
Answer:
114.075 N
798.525 Nm
Explanation:
C = Drag coefficient = 0.5
ρ = Density of air = 1.2 kg/m³
A = Surface area = 9 m²
v = Velocity of wind = 6.5 m/s
r = Height of the tree = 7 m
Drag equation
Magnitude of the drag force of the wind on the canopy is 114.075 N
Toque is given by the product of force and radius
Torque exerted on the tree, measured about the point where the trunk meets the ground is 798.525 Nm
340 ms
I got it right and I hope you do as well
Answer:
Time=15,Mass=3,Acceleration due to gravity=10,Height=50,Power=?.
Power=mgh/t.....which is 3×10×50=1500/15=100Watts.
<h2>Equation of state of an ideal gas</h2>
<em>The </em><em>ideal gas law is derived</em><em> from the ga</em><em>s laws of Boyle, Charles, Gay Lussac and General.</em>
To solve this exercise, we obtain the data of the exercise:
- V₁ = 52 Lt
- P₁ = 1,2 atm
- P₂ = 0.75 atm
- V₂ = ¿?
<em>The general formula of the </em><em>Equations of state of an ideal gas is:</em>
<h3>P₁V₁=P₂V₂, Where</h3>
- P₁ = Initial pressure
- V₁ = Initial volume
- P₂ = End Pressure
- V₂ = Final Volume
We clear the formula, since it is the value that we must calculate.
<h3>
V₂ = P₁V₁ / P₂</h3>
To solve, we substitute our data in the formula; and we solve
<h3>
V₂ = (1,2 atm)·(52 Lt) / 0.75 atm</h3><h3>
V₂ = 0.832 Lt</h3>
Answer:<em> The </em><em>volume that the gas will occupy</em><em> if the pressure increases to 0.75 atm is </em><em>0.832 lt.</em>
