The power output can remain constant, but the forces acting against the projectile will affect its range. The mass of the projectile and the amount of charge can be considered constants unless range changes.
The elevation will then need to factor as a constant and the amount of charge will need to change accordingly.
It depends on what is easier to change.

What affect the phase angle?
Apparent power is the vector sum of a load's true power and its reactive power. If you draw a 'power diagram', the phase angle will be the angle between the true power and the apparent power. If true power is fixed, then increasing the phase angle will result in a greater value of apparent power.
What is the nature of power factor and its variation with firing angle when a single phase voltage controller feeds a resistive load?
With a pure resistive load the Power Factor should be 1.
How thyristor used in induction furnace?
Thyristor is used for Rectifiying and inverting the power supply in induction furnace. The parallel Resonance Coils (Current Control Furnaces) Control the Furance power up to 40% by controlling the firing angle of the rectifier inverter and remaining 60% controlled by inverter thyristor control. In rectifier they are varying the thyristor firing angle from 15 deg to 45 deg. (in sin wave)
What is Relation between loss angle and Power factor?
Power factor = cos (angle)PF=cos @
What does MWp stand for in respect with solar power plant?
It is the nominal output of a solar panel measured as maximum power output under standard test conditions (STC) in a laboratory with light intensity is 1000W/m2. Manufacturers advertise and sell modules based on this value for solar panel efficiency, which is known as "Nameplate Rating" of solar panels or arrays. Needless to mention that the actual power output of solar panel in real life conditions is usually less than the nominal power output. Since various factors like weather and climate or the angle of incidence of the sunlight on the panels affects solar panel efficiency.
What is the relation between firing angle and duty cycle in power converters?
In power converters, the firing angle directly influences the duty cycle, which is the fraction of one cycle in which a signal or system is active. A higher firing angle typically results in a lower duty cycle, leading to reduced output voltage and power. Conversely, a lower firing angle increases the duty cycle, enhancing the output voltage and power. This relationship is particularly evident in phase-controlled converters, where adjusting the firing angle modulates the effective power delivered to the load.
What is firing angle delay?
Firing angle delay refers to the specific time interval in which a control signal is applied to a power electronic device, such as a thyristor or an SCR (Silicon Controlled Rectifier), after the zero crossing of the voltage waveform. This delay is critical in controlling the power delivered to a load by adjusting the phase angle at which the device is triggered. By varying the firing angle, one can regulate the output voltage and current, influencing the performance of AC power control applications, such as in dimmers or motor speed controllers. Essentially, a larger firing angle results in reduced power output.
What is the effect of changing the firing angle?
Changing the firing angle affects the conduction angle of the AC voltage waveform supplied to the load in AC-DC converters like controlled rectifiers. By altering the firing angle, the average output voltage and hence the power delivered to the load can be controlled, affecting the speed or intensity of the load, like in motor control applications.
What is the relationship between the firing delay angle and the input power factor?
The firing delay angle is the point in the AC cycle at which a thyristor starts conducting. By adjusting this angle, the power factor of the system can be controlled as it affects the balance between real power and reactive power. A smaller firing delay angle can improve the power factor by reducing the phase difference between voltage and current.
What is extinction angle control?
extinction angle control is a scheme of forced commutation for power factor improvement in phase controlled convertors/rectifiers. In this scheme the firing angle is adjusted in order to get the desired output or load voltage. By varying the value of extinction angle we can get the desired load voltage and current waveform.......submitted by abhimanyu(sunny)

How does the power input affect the temperature output in a thermal system?
The power input in a thermal system directly affects the temperature output. Higher power input typically results in higher temperature output, while lower power input leads to lower temperature output. This relationship is governed by the laws of thermodynamics.
How does friction affect output force?
Simply put, friction reduces output force. The more friction there is, the less effectively power will be delivered, and this results in reduced output force.
How does force affect power output?
Force affects the speed of power output. If the driving force is slow, the speed of power output will also be sluggish. Alternatively, if the driving force is fast, power output will be able to match the speed.
What is the nature of power factor and its variation with firing angle when a single phase voltage controller feeds a resistive load?
With a pure resistive load the Power Factor should be 1.
What is firing angle in thyristors?
A sinusoidal AC waveform is divided up into 360 degrees, with the positive half and the negative half of the waveform combined into a kind of circle. The firing angle simply refers to the point on the waveform, as measured in degrees (thus 'angle') which the thyristor is triggered into conduction. Answer2: Firing angle is the phase angle of the voltage at which the scr turns on. There are two ways of turning an scr on..one is by applying a gate current or by applying a voltage across the scr until it becomes greater than the breakover voltage.... Answer3: Thyristor need gate current and voltage to make it conduct. The firing angle is the sinusoidal increasing voltage. As it rises a voltage is reached with enough power to fire to trigger the gate. That voltage is the angle considering that a sinusoidal is 360 degrees per cycle.
How do you find power input with given power factor and power output?
Output Power divided by Power Factor.
