Answer:
The space around a charge or a pole in which a force is experienced is called a magnetic field. And a cluster of aligned magnetic atoms is a magnetic domain. When the clustered regions are aligned with one another, they form a magnet
As you illustrate the problem, you may come up with the same diagram as the one shown in the attached picture. The relative velocity is the linear velocity between the two velocities. This is calculated by simply finding the difference of their velocities. Since, the velocity is with respect to Jane relative to Mary, the solution is as follows:
Relative velocity = Velocity of Jane - Velocity of Mary
Relative Velocity = 4.67 m/s - 3.59 m/s =
1.08 m/s
Its 1.6 kg
Remember
E = 1/2mv^2 is the kinetic energy of the ball. The energy is given to you so you need to solve for mass. Rearranging the equation gives you 2E/v^2 = 1.6
Answer:
Option A
interpreting results
Explanation:
In a Scientific research, we first formulate and test hypothesis of the study. A hypothesis is a tentative guess in the study which should be validated in the process of the study. We may have a null and alternative hypothesis. After formulating the study, we conduct the actual study where we get raw data. The raw data is then analyzed, in many cases using statistical analysis tools such as R, python, excel spreadsheet etc. Therefore, the next step after formulating and objectively testing hypotheses is to interpret the results.
As the collision frequency of gas particles increases, the mean free path of the gas particles decreases.
<h3>Frequency </h3>
The number of times a repeated event occurs in a given amount of time is known as its frequency. It is also sometimes called "temporal frequency" to stress the contrast to "spatial frequency" and "ordinary frequency" to underline the contrast to "angular frequency." Hertz (Hz), which is equal to one (event) per second, are the units used to express frequency. The reciprocal of frequency, the period is the length of time occupied by one cycle in a repeating event. When describing the temporal rate of change seen in oscillatory and periodic phenomena like mechanical vibrations, audio signals (sound), radio waves, and light, frequency is a crucial parameter utilized in science and engineering.
