1) – (1/a) 2) 1/a 3) –1 4) –2 Solution: Given x = a(1 + cos θ) dx/dθ = -a sin θ y = a(θ + sin θ) dy/dθ = a + acos θ dy/dx = (a... View Article
For unlike charges, the electric field is zero outside of the smaller magnitude charge. For like charges, the electric field will be zero closer... View Article
The alternating current can be transmitted over a great distance. The transformers can be used to reduce the voltage of the alternating current... View Article
Beyond the event horizon, the gravity is extremely high and anything that enters the black hole can never escape. There is no evidence of what is... View Article
The forward voltage of a silicon diode is approximately 0.7 volts and for a germanium diode, it is 0.3 volts. The peak inverse voltage is the... View Article
When the diode is reverse biased the majority charge carriers are pushed away from the junction and more ions are left at the junction. This... View Article
In Young’s double-slit experiment, interference of the waves caused due to the overlapping of the waves was observed. Thomas Young postulated... View Article
The fringe spacing is called the bandwidth. The bandwidth is given by the formula β = λD/d λ is the wavelength of the light D is the distance... View Article
The distance between two bright fringes is called the bandwidth. The formula for bandwidth is β = λD/d λ is the wavelength of the light D is... View Article
