Sehidy the given figure and calculate the load distance. Given: 325 N, 40 cm Unknown: 650 N, ?

Answers

Answer 1

Answer:

the load distance is approximately 0.2 meters or 20 cm. To calculate the load distance in this scenario, we can use the principle of moments, which states that the sum of clockwise moments about a point is equal to the sum of counterclockwise moments about the same point when an object is in equilibrium.

In this case, we have two forces:

1. A known force of 325 N applied at a distance of 40 cm (0.4 meters) from the point of interest.

2. An unknown force of 650 N applied at an unknown distance, which we need to find.

Let's assume the unknown distance is "d" meters.

Using the principle of moments:

Clockwise Moment = Counterclockwise Moment

(325 N) * (0.4 m) = (650 N) * (d m)

Solving for "d":

d = (325 N * 0.4 m) / 650 N

d ≈ 0.2 meters

So, the load distance is approximately 0.2 meters or 20 cm.

Sean climbs a tower that is 71.3 m high to make a jump with a parachute. The mass of Sean plus the parachute is 81.4 kg. If U = 0 at ground level, what is the potential energy of Sean and the parachute at the top of the tower?

Answers

Answer:

U = 56877.4 J

Explanation:

The potential energy of a body is that which it possesses because it is located at a certain height above the surface of the earth and can be calculated using the following formula:

U = mgh Formula (1)

Where:

U is the potential energy in Joules (J)

m is the mass of the body in kilograms (kg)

g is the acceleration due to gravity (m/s²)

h is the height at which the body is found from the surface of the earth in meters (m)

Data

m= 81.4 kg

g= 9.8 m/s²

h = 71.3 m

Potential energy of Sean and the parachute at the top of the tower

We replace data in the formula (1)

U = m*g*h

U = (81.4 kg)*(9.8 m/s²)*(71.3 m)

U = 56877.4 N*m

U = 56877.4 J

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
