Answer:
A) τ = 1,222 10⁻⁶ N m
, B) w = 0.24 rad / sec
, v = 2.88 10⁻³ m / s
Explanation:
Part A
We can get the torque
τ= F x r
bold are vector
τ = F r sin θ
Let's use according to Newton's law
F - W = 0
F = mg
τ = mg r sin θ
Let's reduce the magnitudes to the SI system
m = 12 ug = 12 10⁻⁶ kg
r = 12 mm = 12 10⁻³ m
Let's calculate
τ = 12 10⁻⁶ 9.8 12 10⁻³ sin 60
τ = 1,222 10⁻⁶ N m
Part B
Let's use Newton's law for rotational movement
τ = I α
The moment of inertia of the antero that we approximate as a particle is
τ = m r² α
α = τ / m r²
α = 1,222 10⁻⁶ / (12 10⁻⁶ (12 10⁻³)²)
α = 0.70718 10³ rad / s²
Angular velocity is
w = w₀ + α t
w = 0 + 0.70718 10³ 0.34 10⁻³
w = 0.24 rad / sec
Angular and linear variables are related.
v = w r
v = 0.24 12 10⁻³
v = 2.88 10⁻³ m / s
Answer:
Well, the three types of comes is Blue, green, and red if that helps :l
Answer:input current= 282mA
Input voltage= 183V
Explanation:
A step up transformer increases the voltage by increasing the number of turns. The number of turns in the secondary coil is usually larger than the number of coils in the primary coil. The formulas for comparing ratio of turns to current and voltage in primary and secondary coils are shown in the image attached. The full solution can a!so be found in the image attached.
To solve the exercise it is necessary to apply the concepts of Mangenetic Force and Energy generated by electric potential.
By definition we know that the energy within an electron through voltage can be expressed as
Where,
e= charge of electron
V= Voltage
The kinetic energy of a moving system can be expressed as
Where,
m = mass
v = Velocity
For energy conservation we have to
Solving to find v,
On the other hand we have that the Magnetic Force can be expressed as,
Where,
q=charge of proton
v=velocity
B= Magnetic field
Angle between the magnetic field and the velocity vector (It is perpendicular in this case)
Using the previous equation from velocity in the Force equation we have,
PART A) Replacing the values to find the force we have,
Here are the answers to the
following questions:
1. spiral
2. spiral
3. rapidly spinning
protogalactic clouds
