Is there a picture that is supposed to be attached?
Well first off we need to check the relationship between the country’s and if any delays are happening during the process of the transportation of the trade. You would also need security and background checks between the traders and the trades being traded and transported to another country. We would also need to know what things to ship and not to ship and make sure everything is safe to be traded.
Answer:
(d) increase by 100%
Explanation:
= initial mass of earth = m
= final mass of earth = (0.5) m
= initial radius of earth = R
= final radius of earth = (0.5) R
= initial acceleration due to gravity of earth = g
= final acceleration due to gravity of earth
initial acceleration due to gravity of earth is given as
Eq-1
Final acceleration due to gravity of earth is given as
Eq-2
Dividing eq-1 by eq-2

inserting the values

= 2 g
So there is 100% increase
1- Classified by texture and composition
2- Rarely has fossils
3- May have alternative bands of light and dark minerals
4- May react with acid
5- May be composed of only one mineral , ex . Quartzite
6- May have layers of visible crystals
7- Usually made of mineral crystals of different sizes
8- Rarely has pores or openings
9- May have bent or curved foliation
