Answer:

$v = 10.89\ m/s$

Explanation:

given,

radius of loop = 12.1 m

to find the minimum speed transverse by the rider to not to fall out upside down

centripetal force = $\dfrac{mv^2}{r}$

gravitational force = m g

computing both the equation]

$mg = \dfrac{mv^2}{r}$

$v = \sqrt{rg}$

$v = \sqrt{12.1 \times 9.8}$

$v = \sqrt{118.58}$

$v = 10.89\ m/s$

Two diodes are in series. The first diode has a voltage of 0.75 V and the second has a voltage of 0.8 V. If the current through

tensa zangetsu [6.8K]

The current in the second diode is 400mA

Data;

First Voltage = 0.75V
Second Voltage = 0.8V
First Current (I) = 400mA
Second Current(I) = ?

<h3>Current In a Series</h3>

The current in the first diode is equal to 400mA. In a series circuit, the current passing the diodes are equal. This implies that the current in the series are equal.

Diodes connected in series will be the equal.

$I_1 = I_2$

Since I1 is 400mA, I2 will be equal to 400mA

$I_1 = I_2\\I_1 = 400mA\\I_2 = 400mA$

The current in the second diode is 400mA
