Answer:
4
Explanation:
1 is correct
Liquids have no definite shape as they take up the shape of the container. Thus, we can say a liquid has no shape of its own but rather has the shape of the container in which it is filled.
2 is correct
When the atmospheric temperature is increased, it also will increase the boiling point of the liquid
3 is correct
This is an extension of the statement 2. While we decrease the atmospheric pressure, we are also decreasing the boiling point
4 is incorrect
A liquid have a definite volume. When we say a volume is definite, it means the volume is fixed and does not change. The volume of liquids is definite for a particular mass of the liquid and does not change
Speed of wave = wavelength * frequency
wavelength = speed / frequency where speed of light is 3.0 * 10^8 hence wavelength = 3.79 * 10^-5
frequency = wavelength/speed
= 1883.6
A pictorial drawing represents three sides of an object in a view. An isometric pictorial is a type of pictorial drawing which is built on three lines called isometric axes.Oblique pictorial on the other hand is used to produce two dimensional images of three dimensional objects.
Isometric pictorial are usually drawn on pictorial line sheets, this makes things easier when it comes to sketching pictorial drawings. But in using pictorial line sheets one has to determine the direction at which the edge will be located and the depth that will be befitting for the drawing.
Oblique pictorial use vanish point, which guide the drawer in his drawing, but he has to make some estimations in order to draw a good oblique diagram.
mathematics, an ordered pair is a pair of objects. The order in which the objects appear in the pair is significant: the ordered pair is different from the ordered pair unless a = b. Ordered pairs are also called 2-tuples, or sequences of length 2.nation:
