Answer:
<em><u>Solid</u> is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter adapts to the shape of its container but varies only slightly in volume; and gas is the state in which matter expands to occupy the volume and shape of its container.</em>
A. Forming
Explanation:
Metal forming is a metallurgical process which involves heating and rolling blocks of steel into flat sheets and bars.
Metal forming is the process of working metals and utilizing its properties to form different shapes.
- Metal forming is made possible by metallic bonds in metals.
- The bulk of the physical properties of metals can be attributed to these bond types.
- In metal forming, metals are shaped into different substances.
- Metal forming preserves the mass of the metallic body and the shapes modified by force.

Answer:
Frequency = 3 Hz
Explanation:
Frequency is a measure of Hertz. Recall that Hertz is the unit expressing cycles/second, where one second is the denominator of the fraction for simplicity. If there are 12 waves every four seconds, and one wave represents one cycle, dividing 12 waves by 4 seconds will give the answer of 3 waves (or cycles) per one second.
Answer:

Explanation:
since force is applied downwards at some angle with the horizontal
so here we will have

now we know that the box will not move if applied force is balanced by frictional force on it
so we will have




so here we can say
