Answer: The terrestrial planets are mainly comprised of silicate minerals and also there is presence of some metals, which were subsequently formed in the geological time scale, after the accumulation of smaller dust particles, due to the gravitational pull, during the time of formation of the planets.

Due to the location of these terrestrial planets near to the sun, their surface temperature is high enough to hold the gases like hydrogen and helium. Thus, they have a high density but less gases compared to the outer planets.

Which law is used to find the magnitude of a magnetic force?
Talja [164]

Answer:

The Flemings left hand rule is used to find the magnitude of a magnetic force

Explanation:

Fleming's left hand rule states that if the first three fingers are held mutually at right angles to one another, then the fore finger points into the direction of magnetic field the middle finger in the direction of current while the thumb points in the direction of force.

Mathematically

Magnetic Force F= BILsinθ

Where

B= magnetic field density Tesla

I= current

L= length of conductor

θ= angle of conductor with field
