First change km/ s into m/s, then use the formula
Lambda = velocity/ frequency
- m1=1500kg
- m_2=3000kg
- v_1=5m/s
- v_2=7m/s
Using law of conservation of momentum
Answer:
Currently in the united states using parallel system
Explanation:
because you can walk with the twomodes with internal combustion engine or running on electric power.
Well, the rings surrounding a planet are made out of rock. A ring surrounding the sun would be impossible since the sun can reach more than 27 million degrees Fahrenheit (15 million degrees Celsius.)
Hope this helped.
Answer:
i3 =11.014A
i5 = 3.15A
Explanation:
Here according to k'chofs first law
i1 =i2 + i3
i3 = i4 + i5
For determine the i1 you have to consider the resultant resistor of the system
4 , 1 and 3 resistors are in pararel
Then, Resultant is
1/4 + 1/1 + 1/3 = 1/ R
R = 12/19
For get total we have to add another remaining 3 resistor because of serious
Then Resultant is = 12/19 + 3
= 69/19
Then using V = IR
40 =i3* 69/19
i3 = 11.014 A
Other 3 resistors are parrarel because of this voltage of those resistors are same.
Then i inversely propotional to its resistor
Then ,
i5 * 2 = (i3-i5)*4/5
i 5 = 3.15 A
