Daguerreotype is defined as the
first practical photographic process which was introduced in Paris on January
7, 1839. To make the image permanent, Daguerre used salt solution. The result
of his introduced process is a finely defined image with surface which is
delicate. The major benefit of daguerreotype is if the images are correctly
preserved, the pictures could last forever. Aside from this, since it produces superior
quality of outline, it is thus suitable for portraitures.
Answer:
6.25 m/s
196 kg/s
Explanation:
The areas of the pipe from big to small:


As the product of speed and cross-section area is constant, the speed in the smaller pipe would be


The mass flow rate would be:

B would be the correct answer. All the other choices consist of physical changes
0.17m/s²
Explanation:
According to newtons second law "the force on a body is depends on its mass and acceleration"
Force = mass x acceleration.
The more the mass and acceleration, the more the force a body possess.
Given that the acceleration of the body is 0.33m/s²
Force = 0.33 x mass
If the force on the body is halved, the acceleration will also be halved;
i.e:
Force = F
= 0.33 x mass
F =
x 0.33 x mass
F = 0.17 x mass
Force = acceleration x mass
Acceleration is 0.17m/s²
