Resistivity measurements on the leaves of corn plants are a good way to assess stress and overall health. The leaf of a corn plant has a resistance of 2.3 MΩ measured between two electrodes placed 20 cm apart along the leaf. The leaf has a width of 2.3 cm and is 0.20 mm thick.Part AWhat is the resistivity of the leaf tissue?Express your answer to two significant figures and include the appropriate units.ρ=________Part BIs this greater than or less than the resistivity of muscle tissue in the human body?(A) greater or(B) less

Answers

Answer:

Part a)

$\rho = 52.9 ohm- m$

Part b)

the resistivity of corn plant is grater than the resistivity of muscle tissue in the human

Explanation:

Part a)

As we know the formula of resistance is given as

$R = \rho (L)/(A)$

here we know that

$\rho = (RA)/(L)$

here we have

$R = 2.3 M ohm$

$L = 20 cm$

$Area = (0.023)(0.20 * 10^(-3))$

$Area = 4.6 * 10^(-6) m^2$

now we have

$\rho = ((2.3 * 10^6)(4.6 * 10^(-6)))/(0.20)$

$\rho = 52.9 ohm- m$

Part b)

Resistivity of mucle tissue of human is is ranging from 15 ohm-m to 50 ohm m so here we can say that

the resistivity of corn plant is grater than the resistivity of muscle tissue in the human

What happens to the current as we increase the amount of stepping of our transformer? Does this help explain why the primary was warm but not the secondary? How does this result demonstrate that we can’t just use a step-up transformer to create free energy?

Answers

Answer:

Current will decrease.

Explanation:

When we increase the number of stepping in transformer, the voltage will increase as its is directly proportional to the number of turn of stepping. Thus as the voltage will increase, current will decrease. As per the equation of ideal transformer, E1 / E2 = I2 / I1

E1 and E2 are the voltages in primary and secondary winding and I1 and I2 are the current.

As the number of turns will be increased more inevitable losses will be generated that dissipates heat thus warming the primary.

Though the conservation of energy is obeyed but losses occur in this scenario hence step-up transformers cannot be used to create free energy.

how are the direction of an object's acceleration and the direction of the same object's change in velocity related

Answers

The question is a lot like asking "How is your age related to
how long you have lived ?"

Those directions must be the same, because "acceleration"
means "change in velocity".

The captain told the passengers that the plane is flying at 450 miles per hour this information describes the planeVelocity
Speed
Acceleration
Direction

Answers

Answer:

The correct answer is speed.

Explanation:

Time rate of change in distance is called as speed. On the other hand, time rate of change in displacement is called velocity. The captain told time rate of change in distance (450 miles/hour) because he did not mention the direction. Hence, 450 miles/hour describes the speed of the plane. We do not identify any relation of this information with direction and acceleration.

speed, why velocity has direction acceleration Is a change in speed and it doesn't give a direction so it's speed
