The answers to the question above would be letters a, b, c, and d. The terrestrial planets are those that are close to the sun, namely, Mercury, Venus, Earth, and Mars. The others are known as the gas giants since they have a thick atmosphere and are considerably cold.

Answer:

<h2>a. Mars </h2><h2>b. Earth </h2><h2>c. Venus</h2>

Explanation:

Terrestrial planets are defined as planets which are formed by silicate. An important characteristic is that these planets have a solid surface. On the other hand, there are gaseous planets, which are bigger and more separated of the Sun.

In our Solar system, there are 4 terrestrial planets, which are Mercury, Venus, Earth, and Mars. Notice that they are the inner planets of the system.

So, in this case, the right chice is a. Mars, b. Earth and c. Venus. All three are terrestrial planets, that is, they have a rock solid surface.

A scientist decides to replicate an experiment completed by another scientist. Which statement describes something that would no

tatyana61 [14]

The statement describes something that would not affect the results of the replicated experiment is option A. (The two experiments were completed by two different people)

<h3>What is an experiment?</h3>

An experiment can be defined as a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried.

Experiments helps in the provision of insight into the cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated.

If two experiments were completed by two different people, it would not affect the results if the experiment is replicated.

The purpose of any experiment is to test or verify a hypothesis

If an electric wire is allowed to produce a magnetic field no larger than that of the earth (0.50×10−4t) at a distance of 12 cm

Studentka2010 [4]

The magnetic field generated by a wire carrying a current I is:
$B(r) = \frac{\mu_0 I}{2 \pi r}$
where r is the distance at which the magnetic field is measured, and $\mu_0 = 4 \pi \cdot 10^{-7} NA^{-2}$ is the magnetic permeability in vacuum.

The problem says that the magnetic field at a distance r=12 cm=0.12 m from the wire must be no larger than $B=0.5 \cdot 10^{-4}T$ . Substituting these values, we can find the maximum value of the current I that the wire can carry:
$I= \frac{2 \pi r B}{\mu _0} = \frac{2 \pi (0.12 m)(0.5 \cdot 10^{-4}T)}{ 4 \pi \cdot 10^{-7} NA^{-2}}= 30 A$
