Answer:
0.0031792338 rad/s
Explanation:
= Angle of elevation
y = Height of balloon
Using trigonometry
Differentiating with respect to t we get
Now, with the base at 200 ft and height at 2500 ft
The hypotenuse is
Now y = 2500 ft
The angle is changing at 0.0031792338 rad/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>
