In the outer layers of earths atmosphere gases are in ionized state primarily on account of cosmic rays . as earth rotates , strong electric current are set up due to movement of ions . these currents form earth magnetic field . and thus two equal and opposite poles of earth formed
In this system we have the conservation of angular momentum: L₁ = L₂
We can write L = m·r²·ω
Therefore, we will have:
m₁ · r₁² · ω₁ = m₂ · r₂² · ω₂
The mass stays constant, therefore it cancels out, and we can solve for ω<span>₂:
</span>ω₂ = (r₁/ r₂)² · ω<span>₁
Since we know that r</span>₁ = 4r<span>₂, we get:
</span>ω₂ = (4)² · ω<span>₁
= 16 </span>· ω<span>₁
Hence, the protostar will be rotating 16 </span><span>times faster.</span>
The answer is enthalphy
Enthalphy especially used in thermodynamic system. It itncludes the internal energy which required to create the system and the ammount of energy required to establish its volume and pressure
Real life products of enthalphy applcation are refrigerator and compressor
Hope this help you out
Answer:
The speed of the object at the lowest point in its trajectory is:
Explanation:
We can use the conservation of energy between the maximum point of swing and the lowest point of the pendulum.
(1)
Where:
- h is the height of the object at 30° with the vertical.
- v is the speed at the lowest point.
We can find h using trigonometry.
Now, using equation (1) we can find v.
I hope it helps you!
