Weight = (mass) x (acceleration of gravity)
-- Acceleration of gravity on Earth = 9.8 m/s²
-- Acceleration of gravity on Planet-Q = 4.9 m/s²
Weight on Planet-Q = (4 kg) x (4.9 m/s²) = 19.6 newtons .
The answer is the second option, or 1/10 the same momentum.
Carbon-14 is naturally created with the interaction of high-energy cosmic rays with atmospheric nitrogen. As part of the atmosphere, living organisms take in the carbon and incorporate this into living tissues. As long as the organism is alive and breathing, it keeps adding new carbon-14. When the organism dies, it stops gaining carbon-14 - or anything else, of course.
Carbon-14 is slightly radioactive, with a half-life of about 5700 years. If we assume that the atmospheric production of carbon-14 has been steady for the last 100,000 years, we can calculate the approximate age of when the organism died by determining what percentage of carbon-14 still exists in the dead material.
Paleo-archaeologists and anthropologists use this information when studying old cultures and civilizations.
Equal temperatures.
Heat energy can be transferred from one place to another by three main processes. In convection, heat energy is carried by the movement of particles of matter. In conduction, heat is transferred by particles vibrating. In radiation, heat is carried directly by electromagnetic waves. During conduction heat travels through solids by conduction. If one end of a metal bar is heated, heat energy moves rapidly along the bar. The hot particles do not move along the bar, but vibrate and pass energy to their neighbors.
Hope it helps! :D
Whenever an object is falling, its potential energy
is decreasing and its kinetic energy is increasing.
Olivia's potential energy is decreasing and her kinetic energy
is increasing as she moves toward the right side of the picture,
all the way from W, through X, to the bottom of the arc.
