Answer:
Explanation:The equation for this is F = -GmM/R^2 where the minus sign says the force is attractive m is 10 kg, M is 20 kg and R is 5 meters. If you crunch the numbers you get an answer of:
The volume of water displace by crown is 10.7 mL. This will be equal to the volume of crown. Mass of crown is 112 g.
Density of a substance is defined as mass of substance per unit volume. It is mathematically represented as follows:
Putting the values,
The theoretical value of density of silver is 
also, 1 mL is equal to 
thus, density will be 10.5 g/mL.
This is approximately equal to the calculated value thus, the crown is made up of silver.
The most correct answer is A. Scientists would conduct a study to discover the amount of biodiversity in the area. From that point onward, if it is found that there is a low biodiversity that may be negatively impacted by construction, scientists would perform further tests such as water quality analyses and comparing their data to other, similar sites. Environmental law, in this case, would not prevent scientists from conducting a study, but would rather prevent developers from continuing until a complete survey of the land has been done.
