Answer: Volume of the tank = 0.274m^3
%V = 57.8%
Explanation: find the attached file for solution
The answer is V=25(7.5/(7.5+5)).
This is the voltage divider equation.
I hope this helps!
Answer:
time tt = 40.76 s
Explanation:
In this exercise we can find the acceleration time, the speed with which the acceleration ends and the rise and flight time
For all these calculations we can use vertical launch kinematics
The speed for maximum height is zero
v² = v₀² - 2 g y
v₀ = √ 2gy
v₀ = √ (2 9.8 980)
v₀ = 138.59 m / s
The time it takes to climb after finishing the acceleration is
v = v₀ - gt
t₁ = v₀ / g
t₁ = 138.59 / 9.8
t₁ = 14.14 s
The acceleration time is
v = v₀ + a t₂
As part of the rest the initial speed is zero
t₂ = v / a
t₂ = 138.59 / 16
t₂ = 8.66 s
The height raised at this time is
y₂ = v₀ t + ½ a t²
y₂ = 0 + ½ 16 8.66²
y₂ = 600 m
Let's look for the descent time, the height of the rocket is
y = y₂ + y₁
y = 600 + 980
y = 1580 m
y = v₀t + ½ g t²
v₀ = 0
t₃ = √ 2y / g
t₃ = √ (2 1580 / 9.8)
t₃ = 17.96 s
Total flight time is
tt = t₁ + t₂ + t₃
tt = 14.14 + 8.66 + 17.96
tt = 40.76 s
Answer:
0.4344A
Explanation:
From Ampere's law, it can be shown that the magnetic field B inside a long solenoid is
Where
B= Magnetic field strenght at distance d
I= current
Permeability of free space ()
N= Number of loops
Our values are defined as follow,
T
As a current required to become 104 times the Earth's magnetic field is required, we use B '
<em>Therefore is needed 0.4344A in the solenoid to produce a magnetic field inside the solenoid, near its center, that is 104 times the Earth's magnetic field.</em>
The gravitational field is the Force divided by the mass
Call g the gravitational fiel, F the force exerted by the earth and m the mass of the telescope.
g = F / m
g=9.1x10^4 N / 1.1 x 10^4 kg = 8.27 N/kg
Note that the unit N/kg is equivalent to m/s^2
