Since the electrons are emitted with zero velocity, the kinetic energy is zero. Therefore, the work function is equal to the energy of the photon: W0=E=2.92×10−19J Step 4: Calculate the Threshold Frequency (v0)The threshold frequency can be calculated using the relationship between ...
An object is dropped from a height of 25 meters. at what velocity will it hit the ground? What is the mass of an object with kinetic energy of 1000 Joules and velocity of 5 meters per second? Use the formula, and show proper working. If an object's kinetic energ...
During the evolution, the vortex is found to transform from a round shape and becomes elongated, and after three weeks its longitudinal scale becomes 4 times larger than the transverse one. During the transformation of a vortex, the kinetic energy and available potential energy decre...
What happens to the average kinetic energy of the molecules of a warm substance when the temperature of the substance is slightly decreased? a. It increases. b. It decreases. c. It becomes zero. d. It remains unchanged. When a liquid substance contains a...
To put it another way, the potential energy of the building mass, the energy of position it had due to its height and the pull of gravity, was converted into kinetic energy, or energy of motion (the report puts the total potential energy for WTC 1 at 4x1011joules). This is the same...
The law of conservation of energy gives us the velocity of the ball, r, as potential energy is converted to kinetic energy:(12)rx22=−Ux=ax−ghx(13)rx=2ax−ghx. The ball must have a real-valued velocity in order to remain within the basin of attraction when the basin moves. ...
Ui is the velocity component in direction i, |U| is the wind speed magnitude, βp is the fraction of mean kinetic energy converted into turbulent kinetic energy, βd is the dimensionless coefficient for the short-circuiting of turbulent cascade, ɛCɛ4 and ɛCɛ5 are model constants...
System-level motion is different than particle-energy or radiation. The black-hole as a whole will have some kinetic energy, the whole thing can move. Otherwise the KE gets converted to mass-energy, just adding to the mass of the BH itself. How does KE get converted into mass-energy ...
