Answer:

Rust occurs when iron or its alloys, such as steel, corrode. The surface of a piece of iron will corrode first in the presence of oxygen and water.The process of rusting is a combustion reaction, similar to fire. Left in contact with oxygen, iron will react with the oxygen to form rust.

Hope this helps!!

will the value of g be affected by the radius of the earth? consider the real shape of the earth. compare the acceleration due t
sp2606 [1]

Answer:

Yes, the value of g affected by the radius.

Explanation:

The formula for the force of gravity of 2 objects is

F_{gravity} = G\frac{m_{1}m_{2}}{r^2}, where m1 and m2 are the masses of the 2 objects, r is the radius, and G is the gravitational constant, which is approximately 6.67 \cdot 10^{-11}.

Therefore, as the radius if bigger, the force of gravity is going to be smaller exponentially.

The tortoise and the hare are having a race over a course of length 0.52 km. The tortoise crawls along at a constant 0.075 m/s w
EastWind [94]

Answer:the hare slept for 1 hr 55minutes.

Explanation: distance is changed to meters = 520m

Speed=distance/time

Speed of tortoise is 0.075m/s=520m/t

Crops multiplying t= 520/0.075 = 6933.3 seconds.

Speed for hare 16.7m/s =260m/t

ie 260m is half of the distance.

t =15.56seconds

Therefore the time slept by the hare = 6933.3- 15.56= 6917.74 seconds.

Converting to hours = 1hr. 55minutes is the time the hare slept.
