When the object is at the focal point the angular magnification is 2.94.
Angular magnification:
The ratio of the angle subtended at the eye by the image formed by an optical instrument to that subtended at the eye by the object when not viewed through the instrument.
Here we have to find the angular magnification when the object is at the focal point.
Focal length = 6.00 cm
Formula to calculate angular magnification:
Angular magnification = 25/f
= 25/ 8.5
= 2.94
Therefore the angular magnification of this thin lens is 2.94

I believe the answer that you're looking for is temperature probe. As you raise the heat of the metal cylinder by a specific, measured number of degrees Celsius, you also record the amount of energy put out by the heat source. Specific heat of a substance is equal to the amount of energy or heat needed to raise a substance by one degree Celsius. Use the equation Q=cmΔT, where Q is heat/energy added, c is the specific heat, m is the mass of the cylinder, and ΔT is the change in temperature of the cylinder.
To solve this problem it is necessary to apply the concepts related to pressure as a unit that measures the force applied in a specific area as well as pressure as a measurement of the density of the liquid to which it is subjected, its depth and the respective gravity.
The two definitions of pressure can be enclosed under the following equations
Where
F= Force
A = Area
Where,
Density
g = Gravity
h = Height
Our values are given as,
If we make a comparison between the lid and the tube, the diameter of the tube becomes negligible.
Matching the two previous expressions we have to
Re-arrange to find h
Therefore the height of water in the tube is 7.9cm
A surface wave is a wave in which particles of the medium undergo a circular motion.
