Correct answer choice is:
3) Friction
Explanation:
Low viscosity relates to materials that are thin, such as water, while high viscosity materials are thick. The viscosity of a fluid is a sum of its opposition to progressive deformation by shear strain or tensile stress. For liquids, it compares to the simple idea of thickness, for example, honey has a very greater viscosity than water.
Answer:
Option (3)
Explanation:
The magma that is comprised of low silica content is termed as low viscosity magma. By low viscosity magma, it means that the magma can easily flow over the surface, without any difficulty. This indicates that there is less friction between the surface and the flowing magma. Friction usually refers to the resistant force that obstructs the flow of a liquid in any direction.
When there is a high frictional force, then the liquid flows very slowly with much difficulty. On the other hand, when there is a low force of friction, then the liquid can flow easily over a surface.
Thus, in a low viscosity magma, there is low silica content, so there is less frictional force between the surface and the magma, and the magma flows easily over the surface.
Hence, the correct answer is option (3).
pH scale ranges from 0 (highly acidic) – 14 (highly alkaline). The pH of a neutral solution is 7. Acidic solution is represented by a value less than 7 on the pH scale.
pH, quantitative measure of the acidity or basicity of aqueous or other liquid solutions.
Scientists use something called the pH scale to measure how acidic or basic a liquid is.
Although there may be many types of ions in a solution, pH focuses on concentrations of hydrogen ions () and hydroxide ions (
).
The scale measures values from 0 all the way up to 14. Distilled water is 7 (right in the middle).

Answer:
they us the pH(potential Hydrogen) scale
Explanation:
Reds are strong acids
yellows are weak acids
green is neutral
blue is kinda basic
and purple is super basic
keep in mind, this is just the litmus paper scale
Answer:by checking for voltage with a neon tester
Explanation:
Hey There!
The device used to determine if there is energy in a wire is called a clamp meter, this device would detect if there are any presents currents in the wire. In order to use this device, you would simply have to attach it on the wire you are testing for.
Another device used to detect energy from wires is called a a non-contact voltage detector. While this device does not operate on all types of wires, it is solely created for AC circuits. Though, it is not preferred to manage the wire as this device sometimes proves to not be very reliable.
