The initial velocity of the airplane is 258.3 m/s and then final velocity of the airplane is 408.3 m/s.
DescriptionWhen gravity first exerts force on an object, its initial velocity defines how quickly the object moves.
The final velocity, on the other hand, is a vector number that gauges a moving body’s speed and direction after it has reached its maximum acceleration.
CalculationAccording to laws of motion,
x = Vi*t = 1/2 at^2
Substituting all the values we have,
10^4 = vi (30) + 0.5(5)(30)
Simplifying it,
Vi = 258.3 m/s
According to motion equations,
Vf = Vi + at
Substituting all the values,
Vf = 258.3 + (30)(5)
Vf = 408.3 m/s
So, we have Initial velocity = 258.3 m/s and final velocity = 408.3 m/s

Two ideal gases, a and b, are at the same temperature. if the molecular mass of the molecules in gas a is twice that of the molecules in gas b, the molecules' root-mean-square speed is?
The molecules' root-mean-square speed is R = 8.31 J/(mole⋅ K)
Thermal Motion: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.
Evaluation :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

Certain heavy industrial equipment uses ac power that has a peak voltage of 703 v. what is the rms voltage?
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 net force on a moving object suddenly becomes zero and remains zero. the object will:_________-
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.
