Answer: Uses of clay are as follows.
Explanation:
Clay is a type of soil whose sediment consists of particles smaller than slit, that is, around 0.004 mm. This means that particles of a clay are very small.
A clay is soft and can be molded to different shapes easily.
Some uses of clay are as follows.
- It is used to make ceramics.
- It is used to make pottery like clay pot to store water in summers.
- It is also used to make tile and china dishes.
Answer:
Un átomo neutro siempre tiene el mismo número de electrones que los protones. Los electrones tienen una carga de -1 y los protones tienen una carga de +1. Por lo tanto, las cargas de los electrones y protones de un átomo "se cancelan". Esto explica por qué los átomos son neutros a cargo.
Answer:
The slope of a velocity graph represents the acceleration of the object. So, the value of the slope at a particular time represents the acceleration of the object at that instant.
Answer:
Yes . Frictions was not included for the calculation for acceleration .
Explanation:
This is because we're considering the weight of an object which isn't acceleration i:e frictionless.
If friction is included, the equation for acceleration becomes.
F= ma,(Newton second law of motion)
where F=frictional force , m =mass of the object and a=acceleration..
So therefore, a = F/m.
Answer:
The wavelength is
The wave number is
The wave function is
Explanation:
From the question we are told that
The frequency of the sound wave is
The speed of the wave is
The wavelength of the wave is mathematically evaluated as
substituting values
The wave number is mathematically represented as
substituting values
The general form of wave function is
given that the amplitude is
While which is the angular velocity is represented as
and k which is the angular wave number is mathematically represented as
The wave function becomes
substituting values
