Human use this wind flow, or motion energy, for the purposes: sailing, flying a kite, and even generating electricity. The terms “wind energy” and “wind power” both describe the process by which the wind is used to generate mechanical power or electricity.
Hello!
In order for an animal to be a vertebrate, it must have a backbone. As can clearly be seen in any image of a sponge, it is a highly asymmetrical simple animal and does not have a backbone. Therefore, a breadcrumb sponge is not a vertebrate, or is an invertebrate.
I hope this helped!
Answer:
107.3g
Explanation:Density = Mass/Volume
There are two methods either by taking the above formula and inserting the values or by using Mass = Denstiy*Volume
Here I have showed you both the ways:
1st
As Desnity is 21.46g/cm^3
Volume = 5cm^3
Let m be mass
21.46g/cm^3=m/5cm^3
Cross multiplication takes place here
21.46*5=m
107.3 =m
Therefore, mass of platinum = 107.3g
2nd
Mass = Denstiy*Volume
Density = 21.46g/cm^3
Volume = 5cm^3
m=21.46g/cm^3* 5g/cm^3
m= 107.3g
