Density is equal to mass divided my volume, so divide 38.6 by 2 to get the answer you need!
Answer:
10 km/L
Explanation:
Given the following from question:
Efficiency of car engine = 25% = 0.25
Average force = 1000 N
Gasoline energy content = 40,000,000 J/L
therefore:
Energy utilized effectively = Efficiency of car engine * Gasoline energy content
Energy utilized effectively = 0.25 * 40,000,000 = 10,000,000 J/L
Distance obtain by car in kilometer per meter = Energy utilized effectively/Average force
Distance obtain by car in kilometer per meter = 10,000,000/1000 = 10,000 m/L = 10 km/L
10,000 meter per liter = 10 kilo meter per liter
Answer:
A stellar collision.
Explanation:
A stellar collision is the coming together of two stars caused by stellar dynamics within a star cluster, or by the orbital decay of a binary star due to stellar mass loss or gravitational radiation, or by other mechanisms not yet well understood.
Answer:
Correct answers are: 4 and 6
Explanation:
First of all this law is very important and almost every where this law is used in current and according to this law,
1. All incoming current to a particular junction is equal to all out going current from that junction .
2. Sum of all the voltage drop across all the element in the particular loop is zero
Current: it is rate of change of charge per unit time and denoted by I.
V=IR
Hence correct options are: 4 and 6
Answer:
d) 2.12 V
Explanation:
E =E° - RT/nF log 1/H⁺ x HSO₄⁻
E = 2.08 - ( .059/2 X log 1/4.5x4.5 )
2.08 - (-0.038 ) = 2.118 =2.12 V
