We Know, F = m*a
Here, F = 34 N
m = 213 Kg
Substitute their values in the equation,
34 = 213 * a
a = 34/213
a = 0.159 m/s²
So, your final answer & the acceleration of the object would be 0.159 m/s²
Hope this helps!
When the substance are moved close together and they move more quickly they get compressed.
Convex lenses when placed in the air, will cause rays of light (parallel to the central axis) to converge.
Converging lenses, commonly referred to as convex lenses, have thicker centers and narrower upper and lower margins. The edges are outwardly curled. This lens has the ability to concentrate a beam of parallel light rays coming from the outside onto a spot on the opposite side of the lens.
The image created is referred to be a genuine image when it is inverted relative to the object. On a screen, this kind of image can be recorded. When the object is positioned at a point farther than one focal length from the lens, a converging lens creates a true image.
A virtual image is one that cannot be produced on a screen and is formed when the image is upright in relation to the object. When an item is positioned within one focal length of a converging lens, a virtual image is created. It creates an enlarged image of the object on the same side of the lens as the image. It serves as a magnifier.

Explanation:
In the figure we can see a sketch of the problem. We know that at the bottom of the U-shaped tube the pressure is equal in both branches. Defining
Ethyl alcohol density and
Glycerin density , we can write:
![\rho_A\times g \times h_1 + \rho_G \times g \times h_2 = \rho_G \times g \times h_3](https://tex.z-dn.net/?f=%20%5Crho_A%5Ctimes%20g%20%5Ctimes%20h_1%20%2B%20%5Crho_G%20%5Ctimes%20g%20%5Ctimes%20h_2%20%3D%20%5Crho_G%20%5Ctimes%20g%20%5Ctimes%20h_3%20)
Simplifying:
![\rho_A\times h_1 = \rho_G \times (h_3 - h_2) (1)](https://tex.z-dn.net/?f=%20%5Crho_A%5Ctimes%20h_1%20%3D%20%5Crho_G%20%5Ctimes%20%28h_3%20-%20h_2%29%20%281%29%20)
On the other hand:
![h_1 + h_2 = \Delta h + h_3](https://tex.z-dn.net/?f=%20h_1%20%2B%20h_2%20%3D%20%5CDelta%20h%20%2B%20h_3%20)
Rearranging:
![h_1 - \Delta h = h_3 - h_2 (2)](https://tex.z-dn.net/?f=%20h_1%20-%20%5CDelta%20h%20%3D%20h_3%20-%20h_2%20%282%29%20)
Replacing (2) in (1):
![\rho_A\times h_1 = \rho_G \times (h_1 - \Delta h)](https://tex.z-dn.net/?f=%20%5Crho_A%5Ctimes%20h_1%20%3D%20%5Crho_G%20%5Ctimes%20%28h_1%20-%20%5CDelta%20h%29%20)
Rearranging:
![\frac{h_1 \times (\rho_A - \rho_G)}{- \rho_G} = \Delta h](https://tex.z-dn.net/?f=%20%5Cfrac%7Bh_1%20%5Ctimes%20%28%5Crho_A%20-%20%5Crho_G%29%7D%7B-%20%5Crho_G%7D%20%3D%20%5CDelta%20h%20)
Data:
![h_1 = 20 cm; \rho_A = 0.789 \frac{g}{cm^3}; \rho_G = 1.26 \frac{g}{cm^3}](https://tex.z-dn.net/?f=%20h_1%20%3D%2020%20cm%3B%20%5Crho_A%20%3D%200.789%20%5Cfrac%7Bg%7D%7Bcm%5E3%7D%3B%20%5Crho_G%20%3D%201.26%20%5Cfrac%7Bg%7D%7Bcm%5E3%7D%20)
![\frac{20 cm \times (0.789 - 1.26) \frac{g}{cm^3}}{- 1.26\frac{g}{cm^3}} = \Delta h](https://tex.z-dn.net/?f=%20%5Cfrac%7B20%20cm%20%5Ctimes%20%280.789%20-%201.26%29%20%5Cfrac%7Bg%7D%7Bcm%5E3%7D%7D%7B-%201.26%5Cfrac%7Bg%7D%7Bcm%5E3%7D%7D%20%20%3D%20%5CDelta%20h%20)
![7.5 cm = \Delta h](https://tex.z-dn.net/?f=%207.5%20cm%20%3D%20%20%5CDelta%20h%20)
Answer: Yes, on many slate-roofed homes as temperatures change, such as cooling at night or heating during the day, thermal expansion or contraction of the slates may cause movement that in turn causes snapping, popping, or cracking noises, even bangs and clanks or clicks from the roof.
