When a valence electron shell becomes full, it will usually become stable.
Answer:
The answer is A, B, C, D
Explanation:
This is because gravity is the weakest force of the four fundamental forces, so it automatically cancels letter E
Answer:
T = 2390 degree C
Explanation:
Given data:
Resistance 12 ohm
Temperature 20 degree C
we know that linear relation between the resistance and temperature is given as
where is resistance at and = coefficient of resistivity
SOLVING FOR
degree C
WE KNOW
T = 2370 + 20
T = 2390 degree C
1 watt means 1 joule of energy per second
The food processor uses 1,150 joules of energy per second.
The blade uses 950 joules per second to slice, dice, and puree.
The rest of the energy goes to heat the appliance's motor, or
overcome friction in the blade's bearings, etc. How much energy
does NOT go into slicing and pureeing ?
(1,150 watts) - (950 watts) = 200 joules per second
1 minute = 60 seconds
2 minutes = 120 seconds
Energy wasted in 2 minutes =
(200 joules/second) x (120 seconds) = <em>24,000 joules</em>
That's enough energy to operate a 34-watt CFL (curly) light bulb
for 11 minutes 46 seconds.
