The direction of the magnetic field between the two cylinders while the capacitor is charging is counterclockwise.
According to Maxwell's law of induction, a changing electric field induces a magnetic field, B given by the equation
∫B.ds = μεdΦ/dt where ds = path length of magnetic field, μ = permeability of free space, ε = permittivity of free space and dΦ/dt = rate of change in electric flux. The electric field in the cylindrical capacitor is directed from the inner cylinder to the outer cylinder since the inner cylinder is positive and outer cylinder negative.
For an electric current which increases, the rate of change of electric flux is positive and this produces a magnetic field in the clockwise direction.
Since in this case, we have an exponentially decreasing current, dΦ/dt is negative. Thus, this will produce a magnetic field opposite to that of an increasing current. So, the direction of the magnetic field would be counter clockwise.
So, the direction of the magnetic field between the two cylinders while the capacitor is charging is counterclockwise.

Fréquence of 20,000hz is called ULTRASOUND
Answer:
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.
Explanation:
yes.
Answer:
The mass of the objects
Distance between the objects
Explanation:
The two factors that determines the amount of gravitational force between two objects is the mass of the objects and the distance between them.
Gravitational force of attraction is directly proportional to the product of the masses of the two objects and inversely proportional to the square of the distance between them. This is the postulate of the newton's law of universal gravitation.
Mathematically:
F = 
m is the mass
r is the distance
G is the universal gravitation constant
Answer:
Explanation:
Let at any moment of time the friend's car is at some horizontal distance "x" from the position of balloon.
Now if the altitude of the balloon is fixed and it is at height "h"
so here we will have
now we know that
initially the angle of the friend's car is 35 degree
so the horizontal distance will be
similarly if the angle after passing the car position is 36 degree
then we have
now the speed of the balloon is constant
so we have
so the final position of friend when the angle is 36 degree
