An electron has an energy of 2.3 eV. What is the kinetic energy of this electron in joules? What is the difference between a photon and an electron? How to find azimuthal quantum number? How to calculate the Rydberg constant for hydrogen ...
up a flight of stairs in 4 S , how much power do you use? Power Expended:The work done in less time demands more magnitude of power so mathematically power is nothing but the dissipation of joules (unit of energy) with respect to time. More dema...
How much work does a 50 kg student to climb 3 meters high stairs? Calculate the work done in joules and the power in watts when an object weighing 100 kg is lifted 3 m in 10 sec at a constant speed. How much work do you do on a 25-kg backpack when you wal...
Before using a crossbow, particularly for hunting purposes, research the laws in your area. Check out the links on the next page for more information on crossbows, physics and other topics. Choosing Bolts The size and strength of a crossbow corresponds to the size and weight of the bolts it...
To find the total energy of the entire system, multiply the number of particles, {eq}N {/eq}, by the average kinetic energy: $$U = 1.5Nk_bT $$ This can also be expressed in terms of the number of moles, {eq}n {/eq}, of gas present in the system by using the mo...
Step by step video, text & image solution for How much force is applied on the body when 780 J of work is done in displacing the body through a distance of 30 m in the direction of force? by Physics experts to help you in doubts & scoring excellent marks in Class 8 exams.Updated ...
A more useful quantity in chemistry, physics and engineering isspecific heat capacity C, measured in units of heat per unit mass. Specific heat capacity units are usually joules per gram-kelvin, or J/g⋅K, even though the kilogram (kg) is the SI unit of mass. One reason specific heat...
Brain is one of the complex organs in our body without which it’s impossible to stay alive. A supercomputer takes millions of joules of energy and thousands of CPU cores and takes several minutes to simulate equivalent to one second of brain activity, whereas our brain might just need a bu...
I’m trying to calculate how many Joules are stored in the Hyperion tree, the worlds tallest (115.84 m). However, I cannot find the mass of said tree, and am trying to find it by multiplying density by the volume (530 m^3) because if p=m/V then p•V=m, but I cannot find ...
The volt as a unit of potential difference is named after Alessandro Volta who did a lot of work with the initial physics of electricity and magnetism. We can examine this further by unpacking energy (in joules) as a force (newtons) over a distance (meters). In this way, the voltage is...
