a) They collide and stick to one another
b) Inside of the star called Sun. On the earth we don't have such materials that would withstand very high temperatures.
c) As it commonly happens today: boil water, get high-temperature steam, rotate turbine connected to a generator and get electricity
d) Sorry, I don't see any charts.
Momentums equation is just p=mv
mass times velocity so 50x200
p=10,000
The appropriate answer is c. silty clay loam. This is the most likely soil that was present in the garden before sand was added to balance it. This type of soil contains an even mix of silt and clay. This type of soil does not drain well and tends to hold water. This would not be suitable for most garden variety plants. Adding sand to the soil ensures better drainage and removes moisture that would rot roots or create conditions for fungi to develop.
