The sun provides the energy that propels water transport in plants.

Photosynthesis is the process by which plants convert light energy into chemical energy that is stored in glucose. This glucose is converted into ATP (adenosine triphosphate), which serves as an energy source for various metabolic processes in the plant, including water transport.

Water is absorbed by the plant's roots and transported upward through the stem and leaves via a process known as transpiration. This process is powered by ATP, which provides the energy required to drive water movement from the roots to the rest of the plant.

So the sun provides the energy for water transport in plants, which is converted into chemical energy through photosynthesis and stored in the ATP.

In aerodynamics, the coefficient of profile drag (Cd) for a flat plate is a frequently used reference measure, and its value depends on the flow circumstances. Cd values for flat plates typically vary from 0.0015 to 0.0050. This value is corrected by a correction factor of 1.75 to account

A dimensionless integer called the coefficient of profile drag (Cd) is used to measure the aerodynamic resistance of an object moving through a fluid, most often air. It is the proportion of the drag force exerted on an item to the dynamic fluid coefficient and the object's reference area. The form, size, direction, and speed of the item, together with the fluid characteristics and flow conditions, all affect the value of Cd. An item with a low Cd value is more aerodynamically efficient, producing less drag and encountering less resistance as it moves through the fluid. On the other side, an item with a high Cd value will produce more drag and be less aerodynamically effective. The Cd rating

The moment of inertia of a rod with respect to an axis perpendicular to its length and passing through its end can be calculated as follows:

I = (1/12) * mL^2,

where m is the mass of the rod and L is its length.

The moment of inertia of a point mass at a distance r from the axis of rotation can be calculated as follows:

I = mr^2.

In this case, the maximum moment of inertia occurs when the two larger weights are placed at the ends of the rod and the pivot point is placed at the middle. This way, both weights are located as far away from the axis of rotation as possible and thus contribute the maximum amount to the moment of inertia.

The moment of inertia in this case can be calculated as:

I = (1/12) * mL^2 + m_1 * (L/2)^2 + m_2 * (L/2)^2

= (1/12) * 2.2 * 1.6^2 + 0.25 * (1.6/2)^2 + 1.0 * (1.6/2)^2

= 0.53 kg m^2.

The radial component of acceleration of a particle moving in a circular path is always directed towards the center of the path.

What is the meaning of acceleration?

The rate at which velocity changes is called acceleration. Acceleration typically indicates a change in speed, but not necessarily. An item that follows a circular course while maintaining a constant speed is still moving forward because the direction of its motion is shifting.

Acceleration occurs in the direction of the velocity change, which is the same direction that the circular path's center of rotation points. The centripetal acceleration typically has a negative sign in vector form. This is due to the centripetal acceleration, which is along the radius vector pointing toward the center of the circular motion, being in the opposite direction to that of the radius vector.

It was found that different atoms and elementary particles, although theoretically having the same amount of matter, have different masses.

Different but physically equivalent conceptual definitions of mass are used in modern physics. Experimental definitions state that a body's mass is a measure of its inertia, or resistance to acceleration (change in velocity), when a net force is applied. An object's mass also affects the gravitational pull it exerts on other bodies.

Explanation:

The acceleration of a cart with a steel ball suspended by two cords are 1/3√3 g.

Please refer to the attached picture below.

From the picture, we know that:

m = steel ball m

Θ = 60°

TA = tension cord A

TB = tension cord B

TA = 2TB

a = cart acceleration

First, we need to draw and define every forces working on the system. Note that the ball is in its static position on its y-axis and only moves on the x-axis.

We will focus on the y-axis first. Since there is no movement on the y-axis, we will use Newton's First Law, where:

∑F = 0

TAy + TBy - m.g = 0

TAy + TBy = m.g

TA sin Θ + TB sin Θ = m.g

2TB sin Θ + TB sin Θ = m.g

3 TB sinΘ = m.g

3 TB sin 60° = m.g

3TB (√3/2) = m.g

TB = 2m.g/3√3 ...  (i)

Next, we will focus on the x-axis. Since there is an acceleration on the x-axis, hence we will use Newton's Second Law where:

∑F = m.a

TAx - TBx = m.a

TA cos Θ - TB cosΘ = m.a

2TB cosΘ - TB cosΘ = m.a

TB cosΘ = m.a

To determine the distance traveled in 22 seconds, we can use the formula:

distance = speed * time

First, we need to convert the speed from km/hr to m/s, which is the standard unit for measuring speed in physics.

1 km/hr = 1000/3600 m/s = 5/18 m/s

So, 650.0 km/hr = 650.0 * 5/18 m/s = 130.9 m/s

Next, we can calculate the distance traveled in 22 seconds:

distance = speed * time = 130.9 m/s * 22 s = 2860.8 m

So, the plane has traveled 2860.8 meters in 22 seconds.

To find the magnitude and direction of the third force such that the resultant of the three forces acts along the positive y-axis with a magnitude of 600 lb, you need to use vector addition.

Let's call the two given forces F1 and F2, and the third force F3. The y-component of the resultant is given by:

Fy = F1y + F2y + F3y = 600 lb

And the x-component of the resultant is given by:

Fx = F1x + F2x + F3x = 0 lb

So, to find F3, we need to determine its x and y components. The direction of F3 can be expressed in terms of its angle from the positive x-axis, denoted as θ. The x and y components of F3 can be found using trigonometry:

F3x = F3 * cos(θ)

F3y = F3 * sin(θ)

Now we have two equations and two unknowns, F3 and θ. Solving for F3:

F3 = sqrt(F3x^2 + F3y^2) = sqrt((F1x + F2x + F3x)^2 + (F1y + F2y + F3y - 600)^2)

And solving for θ:

θ = atan2(F3y, F3x) = atan2(F1y + F2y + F3y - 600, F1x + F2x + F3x)

Note that the atan2 function returns the angle in the range of -π to π, so you may need to adjust the angle to be in the range of 0 to 2π if necessary.

So, to summarize, to find the magnitude and direction of the third force, you need to determine the x and y components of the two given forces, set the x and y components of the resultant equal to zero and 600 lb respectively, solve for the third force, and then find its angle from the positive x-axis.

The diffusivity of a gas in another gas is a measure of the rate at which the two gases mix. At room temperature (25℃), the diffusivity of a gas in another gas can be increased by a factor of 10 by raising the temperature.

The diffusivity of a gas in another gas is proportional to the square root of the temperature. This relationship is known as Graham's law of effusion. Graham's law states that the rate of effusion of a gas is inversely proportional to the square root of its molecular weight. This can be extrapolated to diffusivity by assuming that the molecular weight of the two gases is similar, and that the effusion rate is proportional to the diffusivity.

Therefore, to increase the diffusivity of a gas in another gas by a factor of 10, the temperature must be increased by a factor of 10^2 = 100. This would require a temperature increase of 100 * 25℃ = 2500℃.

It is important to note that this calculation assumes that the gases are dilute and ideal, meaning that they obey the ideal gas law and do not interact with each other. In real-world situations, the diffusivity of a gas in another gas can be affected by factors such as pressure, molecular weight, and intermolecular interactions.

Bernoulli's principle is valid for steady-state, incompressible, non-viscous fluid flow So option D is correct.

Bernoulli's principle states that as the speed of a fluid increases, its pressure decreases, and vice versa. This relationship is based on the conservation of energy in a fluid flow, where the sum of potential and kinetic energy remains constant along a streamline.

For Bernoulli's principle to hold true, certain assumptions must be made about the fluid flow:

Steady-state flow: The fluid flow must be steady, meaning that the fluid velocity and pressure at any given point must be constant over time.

Incompressible flow: The fluid must be incompressible, meaning that its density remains constant as it flows through a pipe or channel.

Non-viscous flow: The fluid must have a low viscosity, meaning that it experiences little friction as it flows.

These assumptions are necessary because Bernoulli's principle is based on the idea of a fluid flowing smoothly and without interruption. In real-world fluid flows, these assumptions are often only approximately true, and the principle must be adjusted accordingly. However, for many applications, the ideal fluid flow assumptions provide a useful starting point for understanding fluid behavior.

Awanita's power output is 8watts

When expressed as an hourly rate of electric energy delivery, power output refers to the average rate of electric energy supply during one metering interval.

To find the power output:

First we find workdone= Force × distance

Given: F=20N , d= 200cm converting to meter: (200/100)m=2m

W= 20×2=40Joules

Power,P= workdone/ time

Given: time=5seconds

P= 40/5= 8 watts
