A unit of mass of steam is expanded in a cylinder in such a manner that no energy is added or lost as heat. what is this process called?

If the net force on an object becomes zero and remains zero, the object will continue to move at constant velocity.

The net force acting on a body is the addition or the resultant of all the forces acting on the body. When the net force acting on a body is more than zero, it causes motion, but when it is zero, the object will remain at rest or will continue moving with uniform velocity.

This is in line with Newton's first law of motion which states that "a body will continue in its state of rest or will continue to move with uniform velocity unless it is acted upon by a force".

Thus, when the net force on a moving body becomes zero, it will not slow down or speed up, it will continue to move at the same speed. An example of this is when the passengers of a moving car fall forward when the car suddenly comes to a stop.

The molecules' root-mean-square speed is R = 8.31 J/(mole⋅ K)

Molecules in any object are in constant motion, the speed of that motion being defined by the temperature of the thing . just in case of ideal gases, the speed of motion is that the function of the temperature and the molar mass of the gas only.

The root mean square speed of the molecules in the gas is given by:  vrms =√3 RT/M

Here,

T is the temperature of the gas;

R = 8.31 J/(mole⋅ K) is the universal gas constant;

M is the molar mass of the gas;

Since the molecular mass of the gas A is twice as large and therefore the speed is inversely proportional to the square root of the molar mass, the speed of molecules in B is bigger by the factor √2 ≈ 1.4

What is molar mass?

The molar mass (symbol M, SI unit kg·mol−1) is defined because the mass per unit amount of substance of a given chemical entity. keep with the definition of the mole, the chemical entity in question should be specified

What is molar mass and mole?

The molar mass of a substance is defined because the mass of 1 mol of that substance, expressed in grams per mole, and is adequate to the mass of 6.022 × 10²³ atoms, molecules, or formula units of that substance

Answer: 5.91836735

Explanation:

For a problem such as this you would use the equation:

V final = V initial +(A*T)

V final = 58 m/s

V initial = 0 (b/c object begins at rest)

A (acceleration) = 9.8 m/s/s

T (time) = X

Time is our unknown variable so you would begin by plugging in your equation with the variables given, which would be:

58 m/s = 0 + (9.8 m/s/s * X)

Then you isolate X by doing:

58 m/s = 0 + (9.8 m/s/s * X)

-0             -0

58 m/s = 9.8 m/s/s * X

(58/9.8)

Getting: 5.91836735 seconds = X as your answer

The RMS voltage of certain heavy industrial equipment is calculated as = 497.09 V . Ac power that has a peak  voltage .

Evaluating :

RMS = [tex]\frac{V_{pk} }{\sqrt{2} } = \frac{703}{\sqrt{2} } \\\\[/tex]

           = 497.09 V .

Simplification :

As the a c current fluctuates, the typical voltage can be computed in terms of the big voltage as using the following equation. Where v r m s is that the average voltage v. Big is that the peak voltage, so this is often the maximum voltage that can be derived from an a c power, therefore the relationship is p r m s equals v peak over square of 2. as long as the peak voltage is equal to 703 volts, we wish to seek out the v r m s. So we're just visiting divide the pick voltage by spirit of 2, which gives us the r m s of 703 over of 2, and this is often 497 point and the unit is same as the piquant, which is volts. So i hope everything is square.

What is RMS voltage ?

RMS or root mean square current/voltage of the alternating current/voltage represents the d.c. current/voltage that dissipates the identical amount of power as the average power dissipated by the alternating current/voltage. For sinusoidal oscillations, the RMS value equals peak value divided by the root of 2.

The mass of the block is 101,700g.

The mass of an object divided by its volume is the formula for determining density. This is expressed mathematically as d = m/v, where d denotes density, m denotes mass, and v denotes object volume. The common measurements are kg/[tex]m^{3}[/tex].

Density = mass / volume

where, volume = l×b×h

volume = 20×30×15

volume = 9000[tex]cm^{3}[/tex]

Now, Density = mass / volume

11.3 = mass / 9000

mass = 101700g

Therefore, the mass of the block is 101,700g.
