The spring .2m far when it is compressed on being supported by a mass of 10kg.
Given: Mass of 30 kg which compresses spring by 0.6m
To find: The compression of the spring when it is supported by a mass of 10 kg
Concept: Compression springs are coiled springs that hold mechanical energy in a compressed state. When these springs are subjected to compressive loads, they compress and shorten, capturing and storing significant potential force.
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
By using unitary method,
10 is 3 times less than 30.
so, 30/3=10
Also applying the same proportion over the lengths compressed,
we get, 0.6/3=.2

Trust me, it's really easy!
break apart the shape (In 3D, I assume.) there should be 6 breaks apart. The top, bottom, and four sides. After you find the area, (Base x Base x Height for the 4 sides, and Side x Side for the top and the bottom of the figure.) Then you add all of them up, and there's the surface area! If you need more help, message me, I'd be glad to help.
The correct answer is Option 4.
Answer:38.5
Step-by-step explanation:
7÷2 = 3.5
11*3.5 = 38.5
