I believe the correct answer is the third option. One advantage of using lasers in cutting patterns instead of traditional cutting machines would be that lasers save time by cutting through more layers of fabric. Although it would cost some energy and the initial cost would be high, you would still be able to save some money as time goes by since you will be able to produce more for a certain period of time as compared to using traditional cutting methods for the same period of time. Also, by using lasers, you can cut complex patterns easily and you will need less people in the production.
Net force is an unbalanced force, so the object will change speed or direction.
Either the object may speed up or slow down.
Each side has to have at least 44 horses
F61160 N. This is further explained below.
<h3>What is the force?</h3>
Generally, We are only interested in the component that operates horizontally since the vertical components all cancel each other out. The pressure difference works on the hemisphere to generate a normal force all over the surface, but we are only concerned with that force's horizontal component. This may be determined by supposing the hemispheres to be two flat circular plates of the same radius as the hemispheres that have been forced together.
Therefore, force is equal to pressure multiplied by area, which is
F= (970 -15 )( * (0.45 m)2)
F=60754 N for each side.
Therefore, each side has to have at least 44 horses
44* 1390 = 61160 N

Answer:
Time taken, t = 4.86 seconds
Explanation:
Given that,
Acceleration of a particular automobile, 
Initial speed of the automobile, u = 75 km/h = 20.83 m/s
Final speed of the automobile, v = 110 km/h = 30.55 m/s
We need to find the time taken to accelerate from u to v. Let t is the time taken. It can be calculate as :
t = 4.86 seconds
So, the time taken by the automobile is 4.86 seconds. Hence, this is the required solution.
