The vector components of the weight force parallel to the plane is 463.4 N, and the component perpendicular to the plane is 166.8 N upward.

A quantity which has both magnitude and direction is termed as a vector quantity. It can be divided into two components in 2-dimensional plane: The vertical component and the horizontal component.

The weight force, which is equal to the force of gravity acting on the yoga instructor, has a magnitude of 490 N, which we can decompose into its vertical and horizontal components using trigonometry:

Vertical component = weight force x sin(20°)

= 490 N x sin(20°)

= 166.8 N (upward)

Horizontal component = weight force x cos(20°)

= 490 N x cos(20°)

= 463.4 N (parallel to the plane)

So the component of the weight force parallel to the plane is 463.4 N, and the component perpendicular to the plane is 166.8 N upward.

Answer:

F = G * (m1 * m2) / r^2

Explanation:

The relationship between mass and gravitational force is directly proportional. This means that as the mass of an object increases, the magnitude of the gravitational force acting on it also increases. The exact relationship can be described using Newton's law of universal gravitation, which states that the gravitational force between two objects is proportional to the product of their masses and inversely proportional to the square of the distance between them.

This relationship can be expressed mathematically as:

F = G * (m1 * m2) / r^2

where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between them.

This relationship makes intuitive sense: larger objects have a greater ability to pull other objects towards them, so the gravitational force they exert is stronger. On the other hand, as the distance between two objects increases, the gravitational force between them decreases, because the pull is spread out over a larger area.

the work done by the ball is 38.72 J.

define work done ?

In physics, work is defined as the product of force and displacement. It is a measure of the energy transferred when a force is applied over a distance, resulting in the displacement of an object. Mathematically, work is represented by the formula:

Work = Force x Distance x Cos(theta)

where Force is the applied force, Distance is the displacement of the object, and theta is the angle between the force and the displacement vectors. The unit of work is the Joule (J), which is equivalent to one Newton-meter (N·m). Work can be positive, negative, or zero, depending on the direction of the force and displacement. If the force is in the same direction as the displacement, work is positive, and if the force is in the opposite direction to the displacement, work is negative. If the force and displacement are perpendicular, the work is zero.

Work = Force x Distance x Cos(theta)

where:

Force = 484 N (given)

Distance = 8 cm = 0.08 m (given)

Cos(theta) = 1 (since the force and displacement are in the same direction)

Plugging in the values, we get:

Work = 484 N x 0.08 m x 1

Answer:

To calculate the forces acting on the block, we can use the following steps:

Draw a force diagram showing all the forces acting on the block. The forces acting on the block are:

Weight (W), which acts vertically downward with a magnitude of W = m * g, where m is the mass of the block and g is the acceleration due to gravity (g = 9.8 m/s^2)

Normal force (N), which acts vertically upward to balance the weight and prevent the block from sinking into the surface of the plane

Frictional force (f), which acts parallel to the plane in the direction opposite to the motion of the block

Applied force (F), which acts parallel to the plane in the direction of the motion of the block

Calculate the component of the weight that is parallel to the inclined plane. The weight can be resolved into two components, one perpendicular to the plane (Wcosθ) and one parallel to the plane (Wsinθ).

Wcosθ = W * cos(25°) = (6 kg) * (9.8 m/s^2) * cos(25°) = 50.18 N

Wsinθ = W * sin(25°) = (6 kg) * (9.8 m/s^2) * sin(25°) = 59.16 N

Calculate the magnitude of the normal force. The normal force is equal to the component of the weight that is perpendicular to the plane.

N = Wcosθ = 50.18 N

Calculate the magnitude of the frictional force. The frictional force is equal to the magnitude of the applied force minus the component of the weight that is parallel to the plane.

f = |F - Wsinθ| = |37173 N - 59.16 N| = 37113.84 N

Note that the frictional force opposes the motion of the block and its magnitude is limited by the maximum static friction force, which is given by fmax = μN, where μ is the coefficient of friction between the block and the plane. In this case, since the block is moving at a constant velocity, the frictional force must be equal to the applied force, so that f = 37173 N and μ can be calculated as μ = f / N = 37173 N / 50.18 N = 739.

Laminar and transverse waves are the two types of waves. Longitudinal waves are similar to those of sound in that they alternate between compressions and rarefactions in a medium, much like transverse waves in that the surface of the medium rises and falls.

What is transverse wave ?

The term "transverse wave" refers to motion in which all wave points oscillate along trajectories that are perpendicular to the wave's forward velocity. Transverse waves include electromagnetic (such as radio and light) and seismic S (secondary) waves. Surface ripples on water are another example.

In a transverse wave, the medium's particles vibrate up and down perpendicular to the wave's direction. In a longitudinal wave, the medium's particles vibrate back and forth parallel to the wave's direction.

A) 130m for distance, 100m for displacement

B)260m for distance, 0m for displacement

Distance is the sum of all movement taken from start to finish, regardless of position or direction. Since we are going from point A, which is halfway through the 30m side, to point B, which is also halfway through another 30m side, we divide both by 2 and add them together to get 30m once more. Then we take into account the long side of the track, measuring 100m, and can decide that the total distance is 130m.

The displacement, however, doesnt take into account the extra 15m travelled on either of the short sides of the track. When talking about displacement, we are only looking at the distance BETWEEN point A and point B, not the real distance travelled to get to them. Think of it as if youve drawn a line between both points and are mesuring that line and that line only. Because that line would have the exact length as the long side of the track, we can decide that the displacement is 100m.

For part B, the distance is easy to find as we just add up all sides of the track. The tricky part is understanding why displacement is zero. Like I said earlier, it's easiest to imagine a line drawn between both points of mesurment when talking about displacement. In this case, we are talking about the jogger leaving from point A and returning to point A. As I'm sure youve guessed, we cannot possibly draw a line between point A to point A, therefore making the displacement 0.

I'm sorry this is a lot of writing, but I, myself, had a lot of difficulty wrapping my head around the concept of displacement and wanted to make sure it was easy to understand. Hope this helps

The car will move at a constant speed once it is unleashed, as is assumed. Hence, there is no acceleration. Newton's second law states that a straight line along zero will appear on the graph if F=ma=m(0)=0, F=0.

Acceleration is the rate at which an object changes its velocity. It is a vector quantity, which means it has both magnitude and direction. The standard unit of acceleration is meters per second squared (m/s²).

Acceleration can be caused by forces such as gravity, friction, and electromagnetism. When a force acts on an object, it causes a change in the object's motion, resulting in acceleration.

The relationship between acceleration, velocity, and time is described by the equation a = (v_f - v_i) / t, where a is acceleration, v_f is final velocity, v_i is initial velocity, and t is time.

Lignite is a low-grade coal with a relatively low carbon content, and is often referred to as brown coal.

With further increases in heat and pressure, lignite is transformed into bituminous coal, which has a higher carbon content and is often used for electricity generation. Finally, with even greater heat and pressure, bituminous coal is transformed into anthracite, which is the highest grade of coal and has the highest carbon content.

The stages of coal formation are important to understand because different types of coal have different uses and properties. For example, anthracite is often used for heating because it burns very cleanly and efficiently, while bituminous coal is often used for electricity generation because it has a higher energy content.
