Given,
F1=50N
F2=80N
θ= 60º
The resultant of vectors acting on a point using parallelogram law is given by,
R =√ (F12+F22+2F1*F2 cosθ) N
therefore,
R =√ (50+80+2*50*80* cos 60º) N
R = 113.57 N
Let the total resistance is Req and dc voltage is V voltage and total current be I amp then.
Total power P = 72W and I = 6A
V*I = 72
Then V = 12V
Current through first resistor is I1 3A let it resistance is R1 then.
12/R1 = 3
R1= 4
Let second resistance is R2 and current flowing through it is...
Answer: - Let E1 be electric field due to charge 16nc. Let E2 be electric field due to charge 8nc.
E = 1 / 4 П Е (q1 / r²)
The resultant electric field is given by = √ (E1² + E2² + 2.E1.E2.cos Ф
Here E1 - 16 x 10⁴, E2 - 8 x 10⁴, since it is equilateral triangle Ф = 60°

In a potentiometer, the driver cell is typically a bipolar junction transistor (BJT) that is biased in the active region. The driven cell is typically a resistor that is connected to the output of the driver cell. The output voltage of the potentiometer is determined by the position of the wiper...
Only superconductors have zero resistance. Typically, that happens under rather special conditions, such as very low temperature and special materials.
But zero resistance (and it really is zero, as far as anyone has been able to determine) does not mean zero impedance. If you connect a voltage...
(Mass of truck) (velocity of truck) = (mass of kitten) (horizontal component of kitten's momentum)
(Mass of kitten) (horizontal component of kitten's momentum) = (mass of truck) (velocity of truck)
(0.6 kg) (horizontal component of kitten's momentum) = (1.2 kg) (4 m/s)
horizontal component of...
Answer:
197.263157895 m/s
169.491525424 m/s

x Denotes position
t Denotes time
Average velocity is given by,
The average velocity is 197.263157895 m/s.
The average velocity is 169.491525424 m/s.
6Ω & 3Ω in parallel so the resultant of it will be -- 1/R= 1/6+1/3...... so its equivalent is 2Ω
2Ω & 6Ω is in series combination so the resultant R= 2 + 6 = 8Ω
8Ω & 8Ω is in parallel combination so the resultant 1/R= 1/8 + 1/8 ..... so its equivalent is 4Ω
4Ω & 4Ω(the resultant of 8Ω & 8Ω) is...
