Which of these best arranges the planets in the solar system in the increasing order of their number of moons?
mars → neptune → uranus → saturn
uranus → jupiter → neptune → saturn
mars → venus → uranus → jupiter
earth → saturn → mars → jupiter

Mars → Neptune → Uranus → Saturn  

Explanation:

The solar system has 8 planets. The 4 outer gaseous planets have many moons as compared to 4 inner rocky planets.

Mercury and Venus have no moons

Earth has 1 one moon

Mars has 2 moons -Phobos and Deimos

Jupiter has 67 moons

Saturn has 62 moons

Uranus has 27 moons

Neptune has 14 moons

Thus, from the given options, the correct order of number of moons is:

Mars (2) → Neptune (14) → Uranus (27) → Saturn  (62)

we need to know the time interval during which the force acts. impulse of force = momentum change

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
