Answer:
750g of Aluminum
Assuming 8.6 cm lenth is the height of the cylinder. The volume of a cylinder is: V =
*r^2*h
V = 3.14cm x 10.24cm x 3.6cm
V = 280cm^3
Now density = mass/volume
2.7g/cm^3 = mass/280cm^3
2.7g/cm^3 x 280cm^3 = mass/<u>280cm^3</u> x <u>280cm^3</u>
= 750g of Aluminum
Answer:
B) Kinetic
Explanation:
Kinetic Energy is energy relating to or resulting from motion. Therefore, the answer to this question is B.
Answer:
A- SImilar to both copper and oxygen
Explanation:
If copper and oxygen react to form copper oxide, a compound of both Copper and Oxygen, they most likely have traits from both elements, therefore its A
4x − 8x= −3
Step 1: Simplify both sides of the equation.
4x−8x = −3
4x + −8x= −3
(4x + −8x) = −3 (Combine Like Terms)
−4x = −3
Step 2: Divide both sides by -4.
−4x / −4
−3
- / −4
so your answer will be x= 3/4
