(a) its total energy and (b) its speed. Rest energy of an electron: The rest energy of an electron is given by the famous Einsteins formula, {eq}E = m\ c^2 {/eq} where c is the speed of light. Answer and Explanation:1
Answer to: Find the length (in meters) of a pendulum that oscillates with a frequency of 0.43 Hz. By signing up, you'll get thousands of...
Your BMR is the amount of energy your body uses per day at rest, at a comfortable temperature, and with an inactive digestive system. We measure that energy in joules or, more commonly, calories. BMR does not include any calories used during exercise or other types of physical activity, no...
Whenever a battery has a specific potential that is used to move a charged particle, then the energy transfer by the battery can obtain with the help of the charge of particle and battery potential. The relation between the energ...
Levitus et al. note that of course this heat won't be instantly transferred to the atmosphere (fortunately!), and that this comparison is simply intended to illustrate the immense amount of energy being stored by the oceans.This heating amounts to 136 trillion Joules per second (Watts), ...
Find the work in Joules done through the first four meters by evaluating integral_{0}^{4} (9t^2+3t) dt. Find the work done by a force F = 6i - 8j + 7k that moves an object from the point (0, 6, 6) to the point (4...
A 30-06 caliber hunting rifle fires a bullet of mass 0.0118, kg with a velocity of 505, m/s to the right. The rifle has a mass of 6.15, kg . What is the recoil speed of the rifle as the bullet l The ...
A particle with unit mass moves under the influence of a force {eq}F(t)=(e^t, t^2, \sin(t)) {/eq}. If {eq}V(0)=(1,2,5) {/eq}, find {eq}V(2) {/eq}. INewton's Second Law: Newton's Second Law of Motion...
The mass of a moving object is 5 kg. If the kinetic energy was measured as 60,000 Joules, find the speed of the object. A hockey puck is hit on a frozen lake and starts moving with a speed of 12.90 m/s. Exactly 6.7 s later, its speed ...
the sum of currents leaving the junction. Another applicable conservation law, which applies to all isolated physical systems, is the conservation of energy. This law is embodied in Kirchhoff's Second Rule ("loop rule"), which states that the sum of potential changes aroun...
