The aluminum horseshoe bend but does not break due to the property of malleability when a blacksmith pounds it into shape with a hammer.
Malleability can be described as a property that makes a metal be changed into thin sheets when being hammered or rolled out without breaking.
This property is held by some metals that can be converted into thin sheets. It includes giving physical forces to metal to make changes in its outside shape. Some metals such as Gold, Silver, Lead, Iron, Aluminum, and Copper, are malleable.
When aluminum metal is being hammered, then at the molecular level, the Al atoms are flexible enough and slide upon each other to obtain a new shape. The bonds between aluminum atoms do not break when hammered.
Therefore, the aluminum horseshoe bend but does not break when a blacksmith hammers it into shape as the aluminum metal is malleable.

Though helium doesn't usually react with other substances due to its full electron shell, it doesn't mean it lacks chemical properties. Properties like atomic number, atomic mass, density, and reactivity are its chemical properties.
The statement that helium does not usually react with other substances is correct. This is due to helium being a noble gas with a complete set of electrons in its outer shell, making it stable and unlikely to participate in chemical reactions. However, this does not mean it has no chemical properties. Properties such as atomic number, atomic mass, density, and the inability to react or bond with other elements are indeed chemical properties.

O A.) Force = Mass x Acceleration
OB.) Mass = Force x Acceleration
OC.) Acceleration = Mass x Force
D.) none of the above
Explanation:
A. Force = Mass x Acceleration
Benefits of friction.
1. Walking. Friction between the soles of our shoes and the ground enables us to walk. The sole of the shoe is held to the ground through friction. This is what is termed as "grip" of the shoe. The more grip a shoes offers, the better and faster we can walk.
2. Writing. Writing using a pen requires friction. It is impossible to hold a pen in the hand without friction because it would slip out. Also the graphite point of the pencil would not make a mark on the paper without friction.
Drawbacks of friction
1. Drag. An aircraft taking off experiences significant friction between it and the air resulting in drag, so much fuel has to be used to create energy to overcome the wind resistance.
2. Surface hindrance. Friction makes moving something heavy from one part of a room to another very difficult. Sliding a large box across the flour takes a lot of energy due to friction between the box and the floor.

The ball isn't moving, so the mechanical energy is zero.
Answer:
16.4 L
Explanation:
we can use the combined gas law equation that gives the relationship among volume, temperature and pressure conditions of gases.
P1V1/T1 = P2V2/T2
STP conditions are standard temperature and pressure conditions
P1 is standard pressure = 1 atm , T1 is standard temperature = 273 K
and V1 is the volume
P2 is pressure, T2 is temperature and V2 is volume at the second instance
temperature is in kelvin scale,
512 ° + 273 = 785 K
substituting the values in the equation
1 atm x 10.0 L / 273 K = 1.75 atm x V / 785 K
V = 16.4 L
new volume is 16.4 L
