A potential problem is that you are willing to accept a 5% chance of being wrong if you reject the null hypothesis.

The significance level is the probability of rejecting the null hypothesis if it is true. For example, a significance level of 0.05 indicates a 5% risk of concluding that there is a difference when there is actually no difference. Rejecting the true null hypothesis results in a Type I error.

The smaller the value of α the more difficult it is to reject the null hypothesis. Therefore, choosing a low value for α can reduce the likelihood of Type I errors. The result here is that if the null hypothesis is false, it may be more difficult to reject using a lower value for α. The alpha value or statistical significance threshold is arbitrary. Which value to use depends on your field of study.

Potential energy is the energy that the skier have at the top of the slope as there will be a equillibrium which means zero velocity and maximum height.

The skier has potential energy at the top of the slope, which he will primarily transform into kinetic energy as he descends the hill. His body and the air, as well as his skis and the snow, will cause some of his PE to be transformed into thermal energy.

The ski lift, which elevated him against gravity, gave him his PE. In an electric motor, the lift transformed electrical energy into kinetic energy. A little portion of this energy was also converted to heat energy by friction in all of the moving elements.

The first law of thermodynamics is exemplified by the energy transformations. Examples of the second law include the losses caused by thermal energy diffusion.

The predicted max humidity of the day is not an input that the lifted index uses. LI is easier and faster to calculate.  the lifted index can be used to forecast thunderstorms.

The lifted index (LI) is the temperature differential between the environment Te(p) and an adiabatically raised air parcel Tp(p) at a certain pressure height in the troposphere (the lowest layer of the atmosphere where most weather occurs), typically 500 hPa (mb). The temperature is expressed in degrees Celsius. When the value is positive, the atmosphere (at that height) is stable; when it is negative, the atmosphere is unstable. Although the lifted index can be used to forecast thunderstorms, convective available potential energy (CAPE) is widely regarded as a superior metric of instability and is favored by many meteorologists for convection forecasting.

According to the given statement x = L / 2√3 in terms of l, is the oscillation period a minimum.

What is oscillation formula ?

In systems that can be characterized by Hooke's law, F = kx, where x is the displacement from equilibrium or deformation and k is the system's force constant, the simplest oscillations occur.

Briefing:

T = 2π√I/mgx

I stands for the moment of inertia about the oscillation axis.

m is the bodily mass.

x is the separation of the mass center from the pivot point.

g stands for gravitational acceleration.

Here , Moment of inertia of a rod about the axis through pivot is given by

I = ML²/12 + Mx²

As the axis of rotation passes past the pivot, we have measured the rod's moment of inertia with respect to it.
