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.

The first thing that needs to be done is to find everything in the same units. 12 hours becomes 43200 seconds. Then find the distance traveled by light in that amount of time. Using the formula v=d/s, manipulate it so it looks like d=v*s. Then plug in the values: d=(3x10^8)*43200, d=1.3x10^13m. But you need to find this in kilometers. To do this, simply divide your answer by one thousand. Thus, a laser beam would travel 1.3x10^10 kilometers in 12 hours.
F = ma.
Note Force should be = 150 N. Acceleration = 30 m/s2 ( Am presuming for your question you meant to write 30m/s2 and not 30m/s as you wrote)
150 = m ( 30)
150/30 = m.
5 = m
Mass of the object = 5 Kg.
