The magnetic field generated by a wire carrying a current I is:
where r is the distance at which the magnetic field is measured, and
is the magnetic permeability in vacuum.
The problem says that the magnetic field at a distance r=12 cm=0.12 m from the wire must be no larger than
. Substituting these values, we can find the maximum value of the current I that the wire can carry:
where r is the distance at which the magnetic field is measured, and
The problem says that the magnetic field at a distance r=12 cm=0.12 m from the wire must be no larger than
Answer:
The height (h) will be:
Explanation:
The scape speed equation is given by:
Now, the speed of the missile is
Using the conservation of energy, we can find the maximu height of the missile.
Let's recall that g = GM/R², using the equivalence principle. When R is the radius of the earth and M is the mass of the earth.
Therefore the height (h) will be:
