Answer:
the crown is false densty= 12556kg/m^3[/tex]
Explanation:
Hello! The first step to solve this problem is to find the mass of the crown, this is found using the weight of the crown in the air by means of the equation for the weight.
W=mg
W=weight(N)=31.4N
M=Mass
g=gravity=9.81m/S^2
solving for M
m=W/g
The second step is find the volume of crown remembering that when an object is weighed in the water the result is the subtraction between the weight of the object and the buoyant force of the water which is the product of the volume of the crown by gravity by density of water
Where
F=weight in water=28.9N
m=mass of crown=3.2kg
g=gravity=9.81m/S^2
α=density of water=1000kg/m^3
V= crown´s volume
solving for V
finally, we remember that the density is equal to the index between mass and volume
To determine the density of the crown without using the weight in the water and with a bucket we can use the following steps.
1.weigh the crown in the air and find the mass
2. put water in a cylindrical bucket and measure its height with a ruler.
3. Put the crown in the bucket and measure the new water level with a ruler.
4. Subtract the heights, and find the volume of a cylinder knowing the difference in heights and the diameter of the bucket, in order to determine the volume of the crown.
5. find density by dividing mass by volume
The strategy that is specifically a competitive advantage-sustaining strategy is differentiation. The correct option is B.
<h3>What is a sustainment strategy?</h3>
This success is provided through a sustainment approach, which encourages salespeople to extend their efforts. There are four business level-strategies.
Each team member builds a repeatable performance that results in incremental gains as they learn to maintain their abilities. An organizational advantage is creating a work environment around this idea.
Therefore, the correct option is B. differentiation.

Explanation:
The transmission of a program, information, code, or command that intentionally causes damage without authorization, to a protected computer.
Melissa virus is a computer program that was meant to cause serious damage to computer system by sending e-mail from an infected computer to the mail address on that computer. The virus was investigated by the FBI's National Infrastructure Protection Center. By transmission of a program, information, code, or command that intentionally causes damage without authorization, to a protected computer, The FBI's NIPC will be able to investigate how Melissa is being proliferated.
