Answer:
Here are three types of probes that land on space physically. Interplantery, orbiters, and landers.
Explanation:
These are the ones that collect data and other stuff from space.
Answer : The correct option is 2.
Explanation :
Number of protons = 7
Number of neutrons = 6
Number of electrons = 10
Protons are those which carries positive charge.
Electrons are those which carries negative charge.
Neutrons are those which do not carry any charge that means neutrons are neutral.
The net charge on an ion = Number of protons present in an ion + Number of electrons present in an ion
The net charge on an ion = (+7) + (-10) = -3
Therefore, the net charge on an ion is (-3).

Explanation:
The crust is the thinnest layer of the earth accounting for only 1% total volume of the planets.
Compositionally, the earth is divided into three layers which are the crust, mantle and the core.
- The crust is the outermost layer of the earth. It rich in silicate minerals. The rocks are classified into igneous, sedimentary and metamorphic rocks.
- The mantle takes up about 84% of the total volume of the earth. It is located in between the crust and the core. It is predominantly made up of ferro-magnesian silicate minerals.
- The cores accounts for slightly 15% of the volume of the earth. It is the center of our geoid shaped earth. It is rich in iron and nickel metals.

mol = 25/12
= 2.083 mol
1 mol = 6.02 × 10^23 atoms
2.083 mol = X
X = 2.083/1 × 6.02 × 10^23
= 1.254 × 10^24 atoms
