Why does Mars not have an electric field and why

Physics
1 answer:
tangare [24]3 years ago
7 0

Answer:

The difference lies in the planets' respective magnetic fields, because while Earth's magnetism comes from within, Mars' does not. Earth's magnetism comes from its core, where molten, electrically conducting iron flows beneath the crust. Its magnetic field is global, meaning it surrounds the entire planet

mamaluj [8]
Fluid clutches are used on equipment that is subjected to higher torque per unit volume. This type of clutch makes use of an incompressible fluid like oil in order to transfer the input of a movement from a pedal and cylinder to an actuating cylinder. Releasing the this clutch would stop the transfer of power but still allowing the engine to turn continuously.

Witch is true according to the law of conservation of energy?
Elanso [62]

Explanation:

The law of conservation of energy is one of the fundamental laws of science that helps to understand energy in nature.

Energy is the ability to do work. There are different forms of energy.

Generally, energy is classified into potential and kinetic forms of energy. Potential energy is the energy at rest in a body. It is due to the position of the body.

Kinetic energy is the energy due to the motion of a body.

There are different forms of kinetic and potential energy and they are related by the law of conservation of energy.

The law states that "in an isolated system, energy is neither created nor destroyed by transformed from one form to another".

An isolated system is a system in which there is no exchange of matter and energy.

Due to this we know that no new energy is created or destroyed, they are only transformed from one form to the other.

Two 2.0cm×2.0cm metal electrodes are spaced 1.0 mm apart and connected by wires to the terminals of a 9.0 v battery. What is the
Fantom [35]

Answer:

The charge on each electrode is

q=0.354 x10^{-12}

Explanation:

The charge to find the equation is development

V=9v

d=1.0 mm\\A=2cm*2cm=0.02m*0.02m\\A=4x10^{-4} \\E_{o} =8.85x10^{-12} (\frac{C^{2} }{N*m^{2} } )

q=C*V

C=\frac{E_{o}*A }{d} \\C=\frac{8.85x10^{-12} *4x10^{-4}  }{0.01}=0.354  \\

q=0.354*9v\\q=3.186x10^{-12} C
