When we examine the structures of the other terrestrial planets in our solar system, we see that their structure is similar to earth’s. why do you think this is the case?

Terrestrial planets are earth-like planets due to the similarities they share with the earth.

Explanation:

Four planets in our ecosystem between the sun and asteroid belt, Mercury, Venus, Mars, and earth are called terrestrial planets. They are similar in terms of composition and structure. They are composed of silicate rocks and metals and thus have a rigid planetary surface.

In contrast to the terrestrial planets, Jupiter, Saturn, Uranus and Neptune commonly called the ‘gas giants’ are composed of hydrogen, helium, water, and other heavier elements and thus lack a rigid planetary surface.

when earth is in rotational motion around the sun,it displaces from its place.

when a ball is placed on an inclined surface it does both the rotational and circular motion.

explanation:

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
