9) A vector describe as a quantity that has both magnitude and direction. 10) We use vectors to describe in physics in physical quantities, including displacement, velocity, acceleration, force, momentum, and torque.

The vector is typically represented by an arrow, with the length of the arrow representing the magnitude of the vector and the direction of the arrow representing the direction of the vector. In addition to the magnitude and direction, vectors also have a starting point and an end point. Vectors can be added together to obtain a resultant vector that represents the sum of the individual vectors. Vectors can also be subtracted, multiplied by a scalar, or divided by a scalar.

For example, displacement is a vector that describes the distance and direction between two points. Velocity is a vector that describes the speed and direction of motion and acceleration is a vector that describes the rate at which velocity changes. Force is a vector that describes the push or pull on an object and momentum is a vector that describes the motion of an object and its resistance to change. Torque is a vector that describes the rotational motion of an object. So therefore vectors are an important tool for physicists because they allow them to describe physical quantities in a way that is both concise and precise.

When a ray of light passes from one medium to another, it changes direction due to a change in speed. This phenomenon is known as refraction. The angle of refraction can be determined using Snell's law, which states that the ratio of the sines of the angles of incidence and refraction is equal to the ratio of the speeds of light in the two media.

In this case, the angle of incidence is 48.5 degrees. Assuming the index of refraction of air is 1, the index of refraction of lucite can be found in a table or by using a refractometer. Let's assume it is 1.5. Using Snell's law, we can calculate the angle of refraction to be approximately 32.9 degrees. Therefore, when a ray of light passes from air into the surface of a lucite block at an angle of 48.5 degrees, the angle of refraction is approximately 32.9 degrees.

Explanation:

When a charged capacitor is disconnected from a battery and the area of the plates is decreasing, the electric field in the capacitor is increasing.

This can be explained by considering the relationship between the electric field, the charge on the plates, and the area of the plates.The electric field in a capacitor is given by the formula E = Q / (ε₀A), where E represents the electric field, Q is the charge on the plates, ε₀ is the permittivity of free space, and A is the area of the plates. When the capacitor is disconnected from the battery, the charge on the plates remains constant. However, as the area of the plates decreases, the denominator in the formula for the electric field (ε₀A) decreases. Since the charge remains the same, this reduction in the denominator results in an increase in the electric field E.

In simpler terms, the electric field in a capacitor is inversely proportional to the area of the plates. As the area decreases, the electric field strengthens. This occurs because the same amount of charge is now concentrated on a smaller surface area, leading to a higher electric field intensity between the plates. Therefore, when a charged capacitor is disconnected from a battery and the area of the plates is decreasing, the electric field in the capacitor increases due to the concentration of charge on a smaller surface area.

Net external force= 6.72 N

The initial velocity of the sprinter is zero. So, we can use the following kinematic equation to find the time taken, t, to cover the distance of 31 m.

s = ut + 1/2 at²s

= 0 + 1/2 × 1.32 m/s² × (31 m)²s

= 639.78 mt

= √(2s/a)t

= √(2 × 31 m / 1.32 m/s²)

= 5.26 s

After 31 m, the sprinter maintains his velocity for the remaining distance, i.e., 100 - 31 = 69 m. We can use the following formula to find the time taken to cover this distance as time, t = distance / velocity.

We know,

velocity = at = 1.32 m/s² × 5.26 s

= 6.96 m/st

= 69 m / 6.96 m/s

= 9.92 s

Therefore, the total time taken by the sprinter to complete the race is:

t = 5.26 s + 9.92 s

= 15.18 s

Find the net external force on the 3.0 kg sprinter, we can use the formula F = ma, where F is the force, m is the mass and a is the acceleration.

Given information:

A man is carrying a mass m on his head and walking on a flat surface with a constant velocity v.

Acceleration due to gravity g.

Distance covered d.

Formula used:

                              Work done = Force × Distance

Let's calculate the work done against gravity as follows:

We know that the force exerted against gravity is given by:

                                          F = mg

Work done against gravity = Force × Distance

                                            = mgd

Where m = mass of object,

        g = acceleration due to gravity

        d = distance covered

Given the constant velocity v, we can use the formula:

                                          v² = u² + 2as

Where u = initial velocity which is zero in this case.

           s = d which is the distance covered.

           a = acceleration which is zero in this case.

                                   v² = 2 × 0 × d = 0

The correct order of increasing impedance is:

C. PZT, gel, skin, matching layer

Impedance is a measure of the opposition to the flow of sound waves in a medium. It depends on the density and speed of sound in the material. In the given options, the order of increasing impedance can be determined by considering the properties of the materials involved.

PZT (lead zirconate titanate) has a higher impedance than gel, skin, and the matching layer. PZT is a piezoelectric material commonly used in ultrasound transducers and has a higher density and speed of sound, leading to higher impedance.

Gel has a lower impedance compared to PZT but higher impedance than skin and the matching layer. Gel is used as a coupling medium between the transducer and the skin to enhance acoustic coupling and minimize impedance mismatch.

Skin has a lower impedance than both gel and the matching layer. It is the outermost layer and acts as an interface between the transducer and the biological tissue.

The matching layer has the lowest impedance among the given options. It is designed to match the impedance of the PZT to the impedance of the tissue being imaged, facilitating efficient sound transmission.

The tractor applies 1,748.418 N to the plow.

Explanation:

Net Force

According to the second Newton's law, the net force exerted by an external agent on an object of mass m is:

Fn=m.a

If the acceleration is zero, then the net force is also zero. That means all forces acting on the mass are balanced.

The tractor drags the m=313 Kg plow at a constant speed, thus the acceleration is zero and so is the net force.

The horizontal forces acting on the plow are:

Since both forces are balanced, then:

Ft=Fr

The friction force is calculated as:

\(Fr=\mu \cdot N\)

Where \(\mu\) is the coefficient of friction between the plow and the ground and N is the normal force. In the situation described, the normal force is equal to the weight of the plow:

\(N=W=m.g=313*9.8=3,067.4\)

The normal force is N=3,067.4 N

The friction force is now calculated:

\(Fr=0.579 \cdot 3,067.4\ N\)

\(Fr=1,748.418\ N\)

Thus, the tractor applies 1,748.418 N to the plow.

Inertial mass and gravitational mass are two different types of mass. The main difference between the two is that inertial mass is the property of an object that determines how much force is required to accelerate it, while gravitational mass is the property of an object that determines the strength of its gravitational attraction to other objects.

Inertial mass is the measure of an object's resistance to changes in its motion. It is the property of an object that determines how much force is required to accelerate it. It is defined as the ratio of the force required to produce an acceleration in an object to the acceleration produced.

Gravitational mass is the property of an object that determines the strength of its gravitational attraction to other objects. It is the property that causes two objects to be attracted to each other. Gravitational mass is the mass that appears in Newton's law of universal gravitation, which states that the force of gravity between two objects is proportional to the product of their gravitational masses and inversely proportional to the square of the distance between them.

The frequency of the waves when a 0.5 kg mass is hanging on the end of a piece of fishing line is determined by the tension and length of the line.

The frequency of the waves on a piece of fishing line can be determined using the formula f = (1/2L)√(T/μ), where f is the frequency in hertz, L is the length of the line, T is the tension in newtons, and μ is the linear mass density of the line in kg/m.

In this case, the mass of the hanging object is 0.5 kg, so the tension of the line will be affected by the weight of the object as well as any other forces acting on it.

Assuming the line is under tension and the mass is held steady, the length of the line will determine the frequency of the waves. A shorter line will have a higher frequency, while a longer line will have a lower frequency.

Additionally, the tension of the line will affect the frequency - a higher tension will result in a higher frequency, while a lower tension will result in a lower frequency.

Therefore, the frequency of the waves when a 0.5 kg mass is hanging on the end of a piece of fishing line will depend on the tension and length of the line.

Newton's first law of motion, sometimes referred to as the law of inertia, states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. When the car stops slowly, its force is lesser than when the car stops harshly. This act of unbalanced force makes the mangoes fly forward.

If the beam of electrons goes undetected, the force on the electron due to the electric force must be the

same magnitude as the force on the electron due to the magnetic force. Therefore, qE = qvB, and solving

for v  that

v =E/B

v = 7900 V/m/(9.1* 10^?3) T

= 86831 m/s.

If the electric ?eld is turned o?, the magnetic force will cause the electron to undergo uniform circular

motion, so qvB = mv2/r. Solving for r we ?nd that

r =mv/qB

=> r = (9.11 * 10^(-31) *86831 )/(1.6*10^(-19) * 9.1*10^(-3)) = 5.4 * 10^(-5) m

What is Force?

The original form of Newton's alternate law states that the net force acting upon an object is equal to the rate at which its instigation changes withtime.However, this law implies that the acceleration of an object is directly commensurable to the net force acting on the object, is in the direction of the net force, If the mass of the object is constant.

generalities related to force include thrust, which increases the haste of an object; drag, which decreases the haste of an object; and necklace, which produces changes in rotational speed of an object. In an extended body, each part generally applies forces on the conterminous corridor; the distribution of similar forces through the body is the internal mechanical stress. similar internal mechanical stresses beget no acceleration of that body as the forces balance one another. Pressure, the distribution of numerous small forces applied over an area of a body, is a simple type of stress that if unstable can beget the body to accelerate.
