Answer:
A. 0.0005u
Explanation:
The mass of an electron in amu = 9.1*10-311.66*10-27=0.0005u.
Answer:
The correct answers are electricity and discharge
Explanation:
Van de Graaff generator is an electrostatic generator. It is used for producing high voltage static electricity. It consists of a hollow metal sphere. The charges is accumulated on it from continuous motion of the belt which is made of an insulating material.
Due to polarization, the charges builds up on an object. Van de Graaf generator is an example of static charge.
Static discharge occurs when the built-up charges flow from the object. Lightning is an example of static discharge. Lightning occurs when the clouds having an opposite charges collide each other.
Therefore, building up electric charges on a Van de Graaff generator is an example of static electricity. Lightening is an example of static discharge.

Answer:
Acidic.
Explanation:
pH is a logarithmic function of [H+]:
pH = −log[H+]
pH is usually (but not always) between 0 and 14. Knowing the dependence of pH on [H+], we can summarize as follows:
If pH < 7, then the solution is acidic.
If pH = 7, then the solution is neutral.
If pH > 7, then the solution is basic.
Given pH is 6.75 so it is acidic.
The concept of water by displacement. D=m/v therefore m=15.5 g and volume=5 mL (final - initial) then calculate the density
Answer:
In physics, refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium.
