It is impossible to get to the center of the earth using a volcano for the following reasons --
1) Lava is super hot, so if you go into a volcano and touch the lava, or get too close, you could get severely injured
2) The center of the earth is even hotter! It's possible for people to melt, so you would most likely melt if you were trying to get to the center of the earth.
Hope this helps! :D
Answer:A force can be described as a push or a pull. Pushes and pulls can be seen to act on objects when they begin to move, speed up, slow down or change direction.
The image gallery on this page shows children at play using push and pull actions to move objects. Children use push and pull all the time while at play. While playing, students learn to manipulate objects and materials and make observations about their actions.
Teachers may use this teaching resource over a number of lessons to explore and develop their students' understanding that a push or a pull affects how an object moves or changes shape.
Explanation:
Amalgamating is the coating of zinc plate with mercury.
Explanation:
r^2= 9×10^9 × 5.87×5.87×10^-16 / 64.9
=47.7× 10^-8
so taking sq. root
r = 6.9 ×10^-4 m
or
r= 6.9×10^ -2 cm
this gives the required seperation
