If i1/i0=4/5, the ratio of i2/i0 is 0.667 when applied across the resistor.

Resistor is defined as a two-terminal passive electrical device that uses electrical resistance as a circuit component. High resistance resistors will withstand a lot of electric current.

We can say that I1 / I0 = 4/5 , I1 = 4 and I0 = 5.

We know that V = IR So, I = V / R

Thus I0 = 5 V /1 so, V = 5

V = IR

5 = 4 x (Ru +Rr)

5 = 4 x (1 + Rr)

Rr = 0.25

So, for I2

V = I2 x R

V = I2 (Rr + Rr + Ru)

5 = I2 x (1.5)

I2 = 3.333

So, the ratio is I2 / I0 = 3.333 / 5 = 0.667

Thus, if i1/i0=4/5, the ratio of i2/i0 is 0.667 when applied across the resistor.

The purpose of the area divider is to accommodate some movement in the membrane itself.

Essentially, a classical particle cannot cross a potential barrier. According to the quantum theory, an exponential with a negative real exponent describes how a particle's motion continues under a barrier. Such a function degrades quickly, and if the width (or height) of the barrier is significant, the amplitude of the wave function behind the barrier is insignificant, making it impossible for a particle to pass through the barrier.

However, the exponent retains an appreciable value behind a relatively narrow and/or low barrier, indicating that a particle may exist there. The likelihood of a particle passing through a barrier is given by the square of the ratio between the transmitted wave's amplitude behind the barrier and the incident wave's amplitude. The transparency of the barrier is the name given to this value.

If a chef drops a pumpkin pie of mass 1.7 kg from a height of 1.875 meter, the time taken by the pie to hit the ground is 0.62 s

According to equations of motion,

s = Distance

u = Initial velocity

t = Time

We'll begin by obtaining the force. This can be obtained as follow:

F = μN

F = 0.75 × 15000

F = 11250 N

Finally, we shall determine the maximum speed. Details below:

F = mv²/r

11250 = (1500 × v²) / 25

Cross multiply

1500 × v² = 11250 × 25

Dive both sides by 1500

v² = (11250 × 25) / 1500

Take the square root of both sides
