## What does H mean in physics?

**Planck's constant**, (symbol h), fundamental physical constant characteristic of the mathematical formulations of quantum mechanics, which describes the behaviour of particles and waves on the atomic scale, including the particle aspect of light. via

## How do you find h in projectile motion?

if α = 0°, then vertical velocity is equal to 0 (Vy = 0), and that's the case of horizontal projectile motion. As sine of 0° is 0, then the second part of the equation disappears, and we obtain : **hmax = h - initial height** from which we're launching the object is the maximum height in projectile motion. via

## How do you solve for height?

So to calculate height, **divide the volume of a prism by its base area**. For this example, the volume of the prism is 500 and its base area is 50. Dividing 500 by 50 results in 10. The height of the prism is 10. via

## Why is Planck's constant h?

Planck's constant, symbolized h, **relates the energy in one quantum (photon) of electromagnetic radiation to the frequency of that radiation**. In the International System of units (SI), the constant is equal to approximately 6.626176 x 10^{-}^{34} joule-seconds. via

## What does T in physics mean?

a = acceleration ∆v = change in velocity ∆t = **elapsed time** The definition of acceleration. via

## What does this mean H?

(H) is an emoticon which means means "**Cool Dude" or "Heart**." This emoticon may be typed as (H), but is more commonly typed as (h). via

## What is the formula of time of flight?

Time of flight is the total time taken to complete the projectile motion, it will be double the time taken to reach the maximum height. Hence, calculate time to reach maximum height by using equation **v=u+at** and taking v = 0 for maximum height. via

## What is formula for mass?

Mass is always constant for a body. One way to calculate mass: **Mass = volume × density**. Weight is the measure of the gravitational force acting on a mass. via

## What is work formula?

**W = F × d**. The dimension of work is the same as that of energy. It is given as, [ML²T^-²]. Unit of Work: The SI unit for the work is joule (J), and it is defined as the work done by a force of 1 Newton in moving an object for a distance of one unit meter in the direction of the force. via

## What is the formula of maximum height?

The maximum height h reached by the projectile is equal to one-half of H, the altitude of this triangle. = H – ½H so **h = H/2**, which is the desired result. via

## How do u find the height of a cylinder?

The values of the radius and volume are placed in the formula to get the volume of the cylinder. Therefore, the height of a cylinder is calculated with the help of the formula, **V/ πr ^{2}**. via

## How do you find length?

## What is Planck's number?

Putting the "quanta" in quantum mechanics

Named for physicist Max Planck, this fundamental physical constant links the amount of energy carried by a photon with its frequency. Currently, scientists calculate Planck's constant to be **6.62607015 x 10^(-34) joule-seconds.** via

## What is c equal to in physics?

**The speed of light in vacuum**, commonly denoted c, is a universal physical constant important in many areas of physics. Its exact value is defined as 299792458 metres per second (approximately 300000 km/s, or 186000 mi/s). via

## Where is Planck's constant used?

What is the use of Planck's constant? Planck's constant is used **for describing the behavior of particles and waves at an atomic scale**. Planck's constant is one of the reasons for the development of quantum mechanics. via
