Answer:

We can easily find out the beginning point of the line by using dot representation. When it comes to position vector, it expresses the exact position of certain object from the starting point of the coordinate system. The vector is a straight line that has a certain end which is fixed to its body

Answer:

Displacement is defined as the distance, in any direction, of an object relative to the position of another object. Physicists use the concept of a position vector as a graphical tool to visualize displacements. A position vector expresses the position of an object from the origin of a coordinate system

Explanation:

The time required for the container to move 2.25 metres down the ramp is roughly 0.104 seconds.

From part (f), we have determined the final velocity of the package to be 1.38 m/s. Using this value along with the distance traveled (Δx = 2.25 m), we can calculate the time elapsed using the kinematic equation:

Δx = (vf² - vi²) / 2a

Substituting the values, we get:

2.25 = (1.38² - 0) / (2 * 0.087)

Solving for time (t), we get:

t = 2.25 * 0.087 / 1.897

t ≈ 0.104 seconds

Therefore, the time elapsed when the package travels a distance of 2.25 m down the ramp is approximately 0.104 seconds.

The force is acting in the +K direction since it is perpendicular to both the velocity and the magnetic field. Force on electron = 3.08 x 10⁻¹⁷ N

Current I = 26 A

Electron velocity V = 4.77 x 10 m/s

Distance r = 1.3 cm

= 1.3 x 10⁻² m 1.

Find the magnetic field:

Formula used to calculate magnetic field is:

B= μ0×I2πr

Where, μ0 = 4π×10⁻⁷B

= μ0×I2πrB

= 4π×10⁻⁷×26 2π×1.3×10⁻²B

= 2.02 × 10^-5 T2.

Find the force acting on the electron, when it moves in the direction directly away from the wire:

Formula to calculate force on electron is:

F= qVBsinθ

Where,F = Force acting on electron

V = Velocity of electron

B = Magnetic field

q = charge of an electron

θ = Angle between the direction of motion of an electron and direction of the magnetic field that, the electron is moving in a direction directly away from the wire, so it is moving perpendicular to the wire.

Therefore, θ = 90 degrees.

So the force can be calculated as:

F= qVB sin 90

F= qVB

Therefore,F = 1.6×10⁻¹⁹×4.77×10×2.02 × 10⁻⁵

F = 3.08 x 10⁻¹⁷ N3.

Find the force acting on the electron, when it moves in the direction parallel to the wire in the direction of the current:

the electron is moving parallel to the wire, so the angle between the direction of motion of the electron and direction of the magnetic field is 0 degrees.

So the force can be calculated as:

F= qVBsinθ

F = 0N₄.

Find the force acting on the electron, when it moves in the direction perpendicular to the wire and tangent to a circle around the wire in the +J direction:

Here, the angle between the direction of motion of the electron and direction of the magnetic field is 90 degrees.

So,θ = 90 degrees

Therefore, the force on the electron can be calculated as:

F= qVB sin 90

F= qVB

Therefore,F = 1.6×10⁻¹⁹ ×4.77×10×2.02 × 10⁻⁵ F

= 3.08 x 10⁻¹⁷ N

The force is acting in the +K direction since it is perpendicular to both the velocity and the magnetic field.

In thermodynamics, heat and work are two ways in which energy can be transferred into or out of a system. The sign convention for heat and work is crucial in thermodynamics calculations.

When supplied to the system, heat is represented by the letter Q, which has a positive sign, and when released, a negative sign.

W stands for work, and it has a positive sign when the system performs work on the environment, and a negative sign when the environment performs work on the system.

Expansion work is the effort put forth by a system when it expands under a continuous external pressure.

A system's work when it grows is beneficial because energy is transmitted from the system to the surrounds and the system is working on its surroundings.

Contrarily, when the system is compressed, the environment works on it and energy is transferred from the environment to the system.

The length of the shadow cast by a person who is 1.82 m tall when a ray of sunlight forms a 24° angle with the ground is approximately 4.09 meters.

To solve this problem, we'll use trigonometry with the given angle and the height of the person to find the length of the shadow. We know that the angle between the sunlight and the ground is 24°, and the person is 1.82 m tall.

We can model this situation using a right triangle, where the person's height represents the opposite side, the length of the shadow represents the adjacent side, and the angle of elevation is 24°. To find the length of the shadow, we can use the tangent function, which is defined as the ratio of the opposite side to the adjacent side in a right triangle.

So, we have:

tan(24°) = opposite side (height of the person) / adjacent side (length of the shadow)

Now, we can plug in the height of the person:

tan(24°) = 1.82 m / length of the shadow

To find the length of the shadow, we can rearrange the equation and solve for it:

Length of the shadow = 1.82 m / tan(24°)

Using a calculator, we find that:

Length of the shadow ≈ 1.82 m / 0.4452 ≈ 4.09 m

There's a constant force of 35 N exerted on the object of mass 2.0 kg, so it undergoes an acceleration a of

35 N = (2.0 kg) a   →   a = 17.5 m/s²

The object travels 8.0 m, so that it attains a velocity v of

v ² = 2 (17.5 m/s²) (8.0 m)   →   v ≈ 16.73 m/s ≈ 17 m/s

The velocity of the 2 Kg object which travels 8 m along the horizontal frictionless surface is 17 m/s

a = F / m

a = 35 / 2

a = 17.5 m/s²

v² = u² + 2as

v² = 0² + (2 × 17.5 × 8)

v² = 280

The size of the image in terms of pixel numbers which is about 27.4 pixels (1000nm / 36.5nm per pixel).

To calculate the resolution of the microscope, we need to use the formula: Resolution = 0.61 x λ / NA, where λ is the wavelength of light and NA is the numerical aperture of the objective lens. Looking at the given information, we see that the microscope objective is an Olympus UplanFLN with a numerical aperture of 1.0 and we are using GFP, which has a wavelength of around 488nm. Plugging these values into the formula, we get a resolution of about 274nm.

Now, to find the size of the image of the microtubule filament, we can use the formula: Size of image = Actual size x Magnification. The magnification of the microscope is not given, so we cannot solve this directly. However, we are given the pixel size of the camera which is 10um. We can assume that each pixel corresponds to a certain magnification factor, which we can calculate by dividing the pixel size by the resolution we just found. This gives us a magnification factor of about 36.5x. Using this factor, we can calculate the size of the image in terms of pixel numbers which is about 27.4 pixels (1000nm / 36.5nm per pixel).

The speed with which a wave travels on this piano string is approximately 537.3 m/s.

To find the speed with which a wave travels on the piano string, we can use the equation:

v = √(T/μ)

where v is the speed of the wave, T is the tension in the string, and μ is the mass per unit length of the string.

Plugging in the values given, we get:

v = √(1300 N / 4.50 10-3 kg/m)

Simplifying this expression, we get:

$v = \sqrt{2.89 \times 10^5 \text{ m}^2/\text{s}^2}$

Evaluating this expression, we get:

v = 537.3 m/s

Explanation:

The angular resolution of a radio wave telescope decreases with decreased disc size which is false.

The angular resolution of a radio wave telescope actually increases with a decrease in dish size. Angular resolution refers to the ability of a telescope to distinguish between two closely spaced objects in the sky. It is determined by the size of the telescope's aperture or dish.

In general, the larger the aperture or dish size of a telescope, the better its angular resolution. A larger dish collects more incoming radio waves, allowing for finer details to be resolved. Smaller dishes, on the other hand, have limited collecting area and, therefore, lower angular resolution. This is why larger radio telescopes are often preferred for high-resolution observations.

So, to achieve better angular resolution, one would typically need a larger dish size for a radio wave telescope.
