Answer:
The number of fission are equal to 1.947 x 10¹⁶
Explanation:
Energy of one fission=208*1.6*10⁻¹³ Joule.
Power of the bulb=120 Watts.
Time t in seconds = 1.5h=5400 seconds
Total energy E=Power* time=120*5400=64.8 x 10⁴ Joule.
Number of fissions N= total energy / energy for one fission
=(64.8 x 10⁴)/(208x1.6x10⁻¹³)
=1.947 x 10¹⁶
Answer:
Equivalent Resistance of Resistors in Parallel is
1/R = 1/r1 + 1/r2 .....
1/R = 1/7 + 1/7 + 1/7
R= 7/3
R=2.33ohms
Answer:
C. 5 miles/ minute north east
Explanation:
magnitude = 10 mi / 2 min = 5 mi/min
Velocity is a vector
A vector always has both a magnitude and direction
