Answer:
The friction coefficient is .
Explanation:
Given that,
Mass of first box = m
Mass of second box = 3m
Let the static friction force on the less massive box is .
Since the small box is not slide, they have the same acceleration.
We need to calculate the acceleration
Using balance equation
....(I)
....(II)
Adding both the equation
Put the value of a in equation (II)
We need to calculate the friction coefficient
Using formula of frictional force
Hence, The friction coefficient is .
Explanation:
The process by which atoms are arranged to form a material with a crystal shape is called crystallization.
With the help of crystallization process we can purify a solid compound.
For example, ice and snowflakes occur due to crystallization of water.
In this process, small quantity of desired solvent is added into the impure solid. Then it is heated to let the solid dissolve and after that it is cooled down so that crystals are formed. Then with the help of vacuum filtration pure solid is extracted.
Answer:
Crystallization is the correct answer.
Explanation:
An indicator of average kinetic energy is temperature. Temperature is directly proportional to Kinetic energy of the molecules of an element.
Answer:
Temperature
Explanation:
The energy contained by a body due its motion is known as kinetic energy.From kinetic theory of gases, the average kinetic energy is proportional to temperature. More the temperature, more would be the speed of the particles. Gases having same temperature would have same average kinetic energy.
Thus, an indicator of average kinetic energy is temperature.
The reflection of Lin Yao at the back of the spoon must be an upright reflection of himself. The back of the spoon is the convex side. When Lin Yao will look at the inner side of the spoon, his reflection will be inverted. This is because the inner side of the spoon is the concave side.
Answer:
It is A upside down and smaller
Explanation:
i just grabbed a spoon and look at myself
it also depends on what side you are looking at if you look at the back side it a normal mirror but if you look at the front its upside down and smaller
The required period of the wave is 0.125 seconds.
In physics, frequency and period are two related concepts that are used to describe the properties of waves. Period, on the other hand, is a measure of the time it takes for one complete cycle of a wave.
Frequency is a measure of how many cycles of a wave occur in one second. It is measured in units of Hertz (Hz), which is defined as cycles per second.
Here,
The period (T) of a wave is the time it takes for one complete cycle of the wave. It is related to the frequency (f) of the wave by the formula:
T = 1/f
Where T is in seconds and f is in Hertz (Hz).
Given that the frequency of the wave is 8 Hz, we can calculate the period as follows,
T = 1/f
T = 1/8
T = 0.125 seconds
Therefore, the period of the wave is 0.125 seconds.
