What is the effect on the speed of a fighter plane chasing another when it opens fire? What happens to the speed of pursued plane when it returns the fire?

The voltage expression for vy in the given RC op amp circuit with a stepped voltage can be obtained by considering the time constant. If the time constant is 4-8, and the expression for the voltage across the resistor R is 8 mF, where T is in ms, the expression for vy can be derived.

In the given RC op amp circuit, the voltage across the resistor R is given by the expression vy = vis * (1 - e^(-t/RC)), where vis is the input voltage, t is the time, R is the resistance, and C is the capacitance.

Given that the time constant is 4-8, we can assume that the product of R and C is equal to this time constant. Let's assume RC = τ, where τ lies between 4 and 8.

Substituting RC = τ and the given expression for vis as 8 mF (where T is in ms), we can write the voltage expression as vy = 8 * (1 - e^(-t/τ)).

This expression represents the voltage across the resistor R, labeled as vy in the op amp circuit, as a function of time and the time constant τ.

Answer:

B

Explanation:

kinetic energy (KE) is the energy possessed by moving bodies. It can be expressed as:

KE = \(\frac{1}{2}\)m\(v^{2}\)

Where: m is the mass of the object, and v its speed.

For example, a stone of mass 2kg was thrown and moves with a speed of 3 m/s. Determine the kinetic energy of the stone.

Thus,

KE =  \(\frac{1}{2}\) x 2 x \(3^{2}\)

     = 9

KE = 9.0 Joules

Assume that the speed of the stone was 4 m/s, then its KE would be:

KE =  \(\frac{1}{2}\) x 2 x \(4^{2}\)

     = 16

KE = 16.0 Joules

Therefore, it can be observed that as speed increases, the kinetic energy increases. Thus option B is appropriate.

vf = final velocity

50 miles/hr + (15 miles/hr/hr • 1 hr) = final velocity

65 miles/hr = final velocity

Answer:

B

Explanation:

your answer is B. 2. 5 m/s to the left

A student with a mass of 50 kg is standing in a canoe the initial velocity of the canoe is 2.5 m/s to the left. The correct option is option (B).

Given that the mass of the student is 50 kg, the mass of the canoe is 30 kg, and the velocity of the student is 1.5 m/s to the right, we can calculate the velocity of the canoe.

Before the jump, the total momentum is the sum of the momentum of the student and the momentum of the canoe, since they are initially at rest.

Total momentum before the jump = (mass of the student + mass of the canoe) × (initial velocity)

= (50 + 30) × 0 = 0

After the jump, the total momentum is the sum of the momentum of the student and the momentum of the canoe.

Total momentum after the jump = mass of the student × velocity of the student + mass of the canoe × velocity of the canoe

Total momentum after the jump = (50 ×  1.5) + (30 × velocity of the canoe)

0 = (50 × 1.5) + (30 ×  velocity of the canoe)

-75  = 30 ×  velocity of the canoe

velocity of the canoe = -75  / 30 = -2.5 m/s

Therefore, the initial velocity of the canoe is 2.5 m/s to the left. Hence, the correct option is (B).

As we move from left to right across the periodic table, the general trend is that the atomic radii decrease and the electronegativity increases while the metallic character decreases and the nuclear shielding remains constant. The option d is correct

The periodic table is an organized arrangement of elements that are ordered according to the periodic law, which is a basic principle of chemistry. This principle explains that the chemical and physical properties of elements are periodic or repeated based on their atomic structure. The table has been designed to demonstrate the relationship between the chemical and physical properties of elements. It comprises 118 elements in total and is arranged in order of atomic number. Elements have been classified into groups based on their chemical and physical properties. Each group is identified by the number of valence electrons the element has, which plays a significant role in determining the element's behavior.  

As we move from left to right across the periodic table, the trend is that the atomic radii decrease due to the increased nuclear charge that attracts the electrons more strongly to the nucleus. This decreases the size of the atom. Additionally, the electronegativity increases because the effective nuclear charge, which is the net charge an electron feels from the nucleus, increases. The metallic character of the element decreases as we move from left to right because the elements lose their metallic character and become non-metallic. Finally, nuclear shielding remains constant because it remains the same across a period. The option d is correct

Matter's particles are in constant random motion or vibration.

Matter is made of small particles.

Explanation:

The 4 kg block exerts a force of 40 Newtons on the 5 kg block. This is calculated using Newton's Second Law, which states that Force = Mass x Acceleration.

The given statement describes the application of Newton's Second Law of Motion, which states that the force acting on an object is equal to the product of its mass and acceleration. In this case, a 4 kg block exerts a force of 40 Newtons on a 5 kg block.

According to the equation of Newton's Second Law, Force = Mass x Acceleration, the force (F) is directly proportional to the mass (m) of an object and its acceleration (a). The greater the mass or acceleration of an object, the greater the force required to accelerate or decelerate it.

In this scenario, the 4 kg block exerts a force of 40 Newtons on the 5 kg block. This means that the force applied by the 4 kg block on the 5 kg block is 40 Newtons. The force is a vector quantity, meaning it has both magnitude (40 Newtons) and direction (direction of the force applied).

It's important to note that the acceleration of an object is caused by the net force acting on it, according to Newton's Second Law. If there is an unbalanced force acting on an object, it will accelerate in the direction of the net force.

The relationship between force, mass, and acceleration as described by Newton's Second Law is fundamental to understanding the motion and dynamics of objects in physics.

In summary, the statement describes the use of Newton's Second Law to calculate the force exerted by a 4 kg block on a 5 kg block, with the force being equal to 40 Newtons. This illustrates the relationship between force, mass, and acceleration, as described by Newton's Second Law of Motion.

Answer:

Muscle memory is found in many everyday activities that become automatic and improve with practice, such as riding bicycles, driving motor vehicles, playing ball sports, typing on keyboards, entering PINs, playing musical instruments, poker, martial arts, and dancing.

Explanation:

a) The attenuation constant of the coaxial cable at a frequency of 100 MHz is approximately 0.0004 nepers/m.

b) To achieve a signal amplitude 15 dB smaller than at the beginning, one needs to travel approximately 6.74 meters along the cable.

a) The attenuation constant (α) of the coaxial cable can be calculated using the formula:

α = √(ωμε/2) * √(σ + jωεtanδ)

where ω is the angular frequency (2πf), μ is the permeability of free space (μ₀), ε is the permittivity of Teflon (εᵣε₀), σ is the conductivity of copper (σ), ω is the angular frequency, and tanδ is the loss tangent.

First, we calculate the angular frequency:

ω = 2πf = 2π(100 × 10⁶) = 2π × 10⁸ rad/s

Next, we substitute the given values into the formula:

α = √((2π × 10⁸ × μ₀ × εᵣε₀)/2) * √(σ + j(2π × 10⁸ × ε₀εᵣtanδ))

Using the values μ₀ = 4π × 10⁻⁷ Tm/A, ε₀ = 8.854 × 10⁻¹² F/m, εᵣ = 2.1, σ = 3.0 × 10⁷ S/m, and tanδ = 0.001, we can evaluate the expression to find α.

b) To determine the distance at which the signal amplitude is 15 dB smaller, we use the formula:

L = (15/α) * (20/ln(10))

where L is the distance traveled along the cable.

Substituting the given attenuation constant (α = 0.05 nepers/m) into the equation, we can solve for L.

The types of exoplanets that are easiest to detect with the transit method are: large planets close to their host stars and hot planets close to their host stars.

What is an exoplanet, An exoplanet or extrasolar planet is a planet that orbits a star outside of the Solar System's planetary system. It is detected indirectly by measuring its gravitational influence on its host star, its thermal or other radiation, or the effects of its atmosphere on the light from its host star as it passes through it.

What is the transit method, The transit method is one of the ways that exoplanets can be detected. It entails detecting a dip in a star's brightness when an exoplanet passes in front of it. A change in the star's apparent brightness is caused by the decrease in the amount of light reaching the observer due to the exoplanet being in the way.

What types of exoplanets are easiest to detect with the transit method, The transit method is most effective for detecting large planets close to their host stars or hot planets close to their host stars. This is due to the fact that such exoplanets are more likely to cause a significant decrease in their host star's brightness when they transit. As a result, smaller exoplanets or those far from their host stars may be difficult to detect with this technique.

This graph shows an object initially travels at a constant velocity for 4 seconds.....the velocity is the slope of the graph for these 4 seconds.  

   then it remains stationary from t = 4 to t =6  ...see the graph is flat (slope = 0   means no velocity) ...at position 3  

  at t = 6 it reverses course ....a negative velocity (steeper slope ...higher velocity)  until it reaches position 0 at t = 9

"Steel is not considered renewable resource as it contains of iron and iron is  found inside the earth."

As they are created over an extended period of time by geological processes, minerals and metals are non-renewable resources.

Only iron can be used to make steel, and in order for iron to be effective, it must first be mined from the earth. Despite being the fourth most frequent material on Earth, there is a finite amount of iron, and once it is all used up, there will be no way to make more steel.

Instead, direct-reduced iron plants can be used by steelmakers to react the rock with gas in order to remove iron from ore. Then, using an electric arc furnace powered by sustainable energy, these iron pellets can be transformed into steel.

Steel is therefore not regarded as a renewable material.

part a) Thus, the torque on the shoulder about the steel ball is, 13.8 N⋅m. part b) The magnitude of the torque about his shoulder if he holds his arm straight, but 60 ∘ below horizontal is 6.60 N⋅m.  are the answers

Part A:

The athlete has held the steel ball at his arm's end, so the gravitational force on the ball generates torque, creating a twisting force about the shoulder. The torque on the athlete's shoulder is the product of the force and its perpendicular distance from the shoulder.

Therefore, the torque on the shoulder about the steel ball is given by:

τ = r × F = m × g × r⊥

where, τ is torque, r is the perpendicular distance between the ball and the shoulder, F is the gravitational force on the steel ball, m is the mass of the steel ball, g is the acceleration due to gravity (9.8 m/s²)r⊥ can be calculated using the Pythagorean theorem,

r⊥ = √(r² - h²)r⊥ = √(0.7² - 0.06²) = 0.699 m

The mass of the steel ball is 2.0 kg and the acceleration due to gravity is 9.8 m/s².

So, the gravitational force on the steel ball,

F = m × g = 2.0 × 9.8 = 19.6 N

Thus, the torque on the shoulder about the steel ball is,

τ = m × g × r⊥ = 2.0 × 9.8 × 0.699 = 13.8 N⋅m

Part B: When the athlete holds the ball at 60° below horizontal, then the angle between the arm and the vertical is 30°, and the gravitational force can be split into two components, one parallel to the arm and one perpendicular to it. The perpendicular component of the gravitational force generates torque about the shoulder.

The perpendicular component of the gravitational force is given by:

F⊥ = F sin(θ)

where, θ is the angle between the force and the arm.

F = m × g = 2.0 × 9.8 = 19.6 N

So, the perpendicular component of the gravitational force,

F⊥ = F sin(θ) = 19.6 sin(30) = 9.8 N

The perpendicular distance from the ball to the shoulder can be calculated using the cosine rule:

L² = r² + h² - 2rh cos(θ)L = √(r² + h² - 2rh cos(θ))L = √(0.7² + 0.06² - 2 × 0.7 × 0.06 cos(30))L = 0.673 m

The torque about the shoulder is given by,

τ = r × F⊥τ = L × F⊥τ = 0.673 × 9.8 = 6.60 N⋅m
