An inflated balloon released from rest moves horizontally. The law that best explains this event is.

Answer: if the acceleration has the opposite sign as the velocity, the object will be slowing down.

Explanation:

The dry and wet adiabatic rates Leeward.

Clouds form when warm air masses which are less dense than cold air masses, rise. The jet stream plays an important role in locating mid-latitude cyclones. The jet stream brings cold air to the northern and southern regions of the United States. A front separates these two air masses.

A front is a boundary separating air masses of different densities, one warmer and often wetter than the other. A warm front occurs when the surface of the front shifts so that warm air occupies an area previously covered by cold air. Endothermic processes absorb heat and cool the surroundings.

The weight of the object is 981 Newton.

Weight is a measurement of how much gravity is pulling on a body.

The weight formula is as follows: w = mg

Since weight is a force, it has the same SI unit as a force, which is the Newton (N). When we look at how weight is expressed, we can see that it depends on both mass and the acceleration caused by gravity; while the mass may not change from one location to another, the acceleration caused by gravity does.

Given parameter;

Mass of the object, m = 100kg.

we know: Acceleration due to gravity on earth is 9.81 m/s².

Hence, weight of the object is = mg = 100 kg × 9.81 m/s² = 981 kg·m/s² = 981 Newton.

So, its weight is 981 N.

An object in each second of free fall than falls a greater distance than it did in the previous second.

In mechanics, "freefall" refers to the condition of a body when it is subject to gravity and can move freely in any direction. In the Sun's gravitational field, the planets, for instance, are falling freely. Because both the ship and the astronaut are falling, weightlessness is felt by an astronaut orbiting the Earth in a spacecraft. Even though they are both subject to Earth's gravitational pull, the spacecraft stays in orbit around the planet thanks to its forward momentum. Only the center of mass is falling freely because gravitational forces are never uniform. Tidal forces are present at all other places of a body because they move in a slightly different gravitational field.

Project Management is one of the methods offered for the purpose of managing a project, namely a management method developed scientifically and intensively since the mid-20th century to deal with specific activities in the form of projects.

Project Management is an attempt at an activity so that the purpose of the activity can be achieved efficiently and effectively. Effective in this case is where the results of the use of resources and activities are in accordance with the target which includes quality, cost, time and others.

While efficient means the use of resources and the selection of sub-activities appropriately which includes the amount, type, time of use of other resources and others. Therefore project management in a construction project is something that cannot be simply ignored, because without project management, construction will be difficult to run as expected in terms of cost, time and quality.

By Using Ideal Gas Equation, we calculate the ratio of the temperature of helium (He) to that of hydrogen (H2) is 4.

According to the ideal gas equation,  we have :

PV = nRT

It is given that the Pressure and Volume of both gases are equal, So,

It can be concluded that,

nT = Constant

Let [tex]n_{1}[/tex] and [tex]n_{2}[/tex] be the number of moles of Helium and Hydrogen respectively. Then

[tex]n_{1} T_{1} =n_{2} T_{2}[/tex]

Now,

The total mass of both gases is the same,

So, [tex]m_{1} =m_{2}[/tex]

The mass of the element is the product of the number of moles (m) and the molar masses (M).

So, [tex]n_{1} M_{He} =n_{2} M_{H}[/tex]

[tex]M_{He} =4M_{H}[/tex]

This implies, [tex]4n_{1} =n_{2}[/tex]

Now, using this in equation (1), we have :

[tex]n_{1} T_{1} =n_{2} T_{2}\\\\n_{1} T_{1} =4n_{1} T_{2}\\\\\frac{T_{1} }{T_{2} } =\frac{n_{2} }{n_{1} } = 4[/tex]

The fraction is f = 84.196 % which is equivalent to 84%

We know that the value of acceleration due to gravity is

g = 9.8m/s^2

y₀ = 1 m

x = 10 m

and the time taken is not given

thus time taken = t sec

A₀ = π 1.5²

Thus the equation becomes;

y = y₀ + ut + 1/2 gt²

⇒ 0 = y₀ - 1/2 gt²

⇒ t = [tex]\sqrt{\frac{2y.}{g} }[/tex]

After substituting the values we get

⇒ t = 0.45152 seconds

Thus x = x₀ + vt

10 = 0 + 0.45152 v

On further solving we get

v = 22.14741 m/s

From continuity equation we get

Av = A₀v₀

On substituting the values we get

⇒ A = 1.11706 cm^2

Thus the fraction is given by

f = ( A₀ - A ) / A₀ X 100 %

Diffraction depends on the ratio of wavelength to linear dimension of obstacles in the optical path.

What is a diffraction angle?

Diffraction depends on the ratio of wavelength to linear dimension of obstacles in the optical path. The smaller the value of this ratio, the less diffraction. As an example, consider Fraunhofer diffraction from a single slit. where the width of the slot is the linear dimension of the obstacle. We call the slit an obstacle because only a limited portion of the wavefront in the plane of incidence can pass through it. In fact, we define diffraction as the effect caused by a finite portion of the wavefront.

For a single slit, finding the angular distance between the main maxima and the first minima gives a rough idea of ​​how much diffraction is occurring.

What is wavelength?

Wavelength is the distance between identical points (adjacent peaks) in adjacent cycles of a waveform signal propagating in space or along a line. For wireless systems, this length is usually specified in meters (m), centimeters (cm), or millimeters (mm). For infrared (IR), visible light, ultraviolet (UV), and gamma rays (γ), wavelengths are more commonly specified in nanometers (nm), with units of 10-9 m or Angstroms (Å). , which is in units of 10-10 m.
