**Answer:**

Radio stations have dipole type antennas

this field increases in intensity and propagates outwards,

**Explanation:**

Radio stations have dipole type antennas, that is, all sides are isolated from each other, when the AC signal from the radio station arrives, the lcharge begins at times and by the Lens law a field appears that opposes this movement, this field increases in intensity and propagates outwards, when the voltage reaches a maximum, the generated wave also reaches the maximum, now the incident wave begins to decrease, an electric hand appears to oppose this prisoner, and in this way a cap is created. electric .

Velocity includes direction, for instance going 140 MPH is speed but going 140 MPH North is velocity

**Answer:**

The objects were 1.8m apart.

**Explanation:**

We will start stating the Coulomb's Law. It says that:

Where F_e is the electric force between the objects, q_1 and q_2 are the magnitude of the charge of the objects, r is the distance between them and K is the Coulomb's constant ( in vacuum). Solving for the distance r we have:

Plugging the given values into this equation, we obtain:

In words, the two charged objects were 1.8m apart.

1.) when the distance between the two objects is dubled then the gravitational Force btw them is **<u>reduced by 4 times</u>** I.e it becomes 1/4 of original due to the **<u>inverse square law.</u>**

2.) because the distance from the center of earth and pole is less then the distance btw pole and equator that's why due to **<u>inverse square law</u>** .

the gravitational Force on object at equator is less then the object on poles.
