According to the octet rule, an
atom with two electron shells is most stable when it contains eight electrons. The
answer is letter B. All atoms wanted to attain a stable energy level equal to
that of the noble gases. A noble gas is where all valence electrons in the
valence shell is completely filled.
25.030: 5 because zeroes are after decimal
0.006: 3 because 2 zeroes are after decimal
1.004: 4 because zeroes are between numbers
(Not sure what you meant to write for these)
1.300520: 7
1.3005: 5 because zeroes are after decimal and between numbers
20: 1 because zero isn't after a decimal or between numbers
Numbers other than 0 are always SigFigs!
Hope I helped! :)
Force = mass * acceleration
Here is an equation for force, used to calculate force.
Look at it this way:-
Joules is used to measure force, while mass is measured by kg. Acceleration is measured by m/s/s (meters per second per second, or meters per second squared.)
joules = m/s/s * kg
Which makes everything fit in just right! :D
Answer:
Thermopile is an electronic device that converts thermal energy into electrical energy.
A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.
