The answer is 8.
The innermost shell can only hold 2 electrons, but the second shell (and other shells afterward) can hold 8 or more (depending on the level).
Answer:
The kinetic energy of the cell phone is 9J
Explanation:
The kinetic energy is the energy possessed by a body by virtue of motion.
The kinetic energy is expressed as
KE= 1/2m(v)²
Given data
Mass of cell phone m= 80g--to kg=80/1000= 0.08kg
Velocity of cell phone v= 15m/s
Substituting our given data we have
KE= 1/2*0.08(15)²
KE= (0.08*225)/2
KE=18/2
KE= 9J
Answer: radio and television
Satellite orbits with an East-West orientation are best used
for communication purposes. The satellite orbit should always be suited for its
purpose. Radio and television are powered by numerous satellites rotating the
Earth from east to west.
No it isn't. energy from the sun travels to us in the form of radiation.
Answer: Boiling begins at this point
Explanation:
When the vapour of a liquid is equal to the external pressure the molecules are fully energised to be mobile thereby creating more motion, so boiling is achieved.
