The final momentum of the two bodies in a completely inelastic one-dimensional collision can be determined by using the principle of conservation of momentum.

When two bodies collide in a completely inelastic one-dimensional collision, they stick together and move with a common velocity after the collision. In such a collision, the principle of conservation of momentum is applicable. According to this principle, the total momentum of the system before the collision is equal to the total momentum of the system after the collision. Therefore, we can write:Initial momentum of body 1 + initial momentum of body 2 = final momentum of the combined system .Therefore, P1i + P2i = Pfwhere P1i and P2i are the initial momenta of the two bodies and Pf is their final momentum after collision.

Given that the initial momenta of the two bodies are:(a) P1i = 10 kg.m/s and P2i = 0(b) P1i = 10 kg.m/s and P2i = 4 kg.m/s(c) P1i = 10 kg.m/s and P2i = -4 kg.m/sFor each case, we can find the final momentum of the combined system as follows:(a) P1i + P2i = Pf10 kg.m/s + 0 = PfPf = 10 kg.m/sThe final momentum of the combined system is 10 kg.m/s.(b) P1i + P2i = Pf10 kg.m/s + 4 kg.m/s = PfPf = 14 kg.m/sThe final momentum of the combined system is 14 kg.m/s.(c) P1i + P2i = Pf10 kg.m/s + (-4 kg.m/s) = PfPf = 6 kg.m/sThe final momentum of the combined system is 6 kg.m/s.

The Bronsted-Lowry model focuses on the transfer of H⁺ in an acid-base reaction.

According to the Bronsted-Lowry theory, often known as the proton theory of acids and bases, any substance that can transfer a proton to another substance is an acid, and the substance that accepts the proton is a base. Because it makes up the nucleus of a hydrogen atom, a proton is a nuclear particle with a unit positive electrical charge; it is denoted by the symbol H⁺.

The Bronsted-Lowry scheme states that an object can only act as an acid in the presence of a base and that an object can only act as a base in the presence of an acid. In addition, when a basic substance obtains a proton, it generates an acid known as the conjugate acid of a base, and when an acidic substance loses a proton, it forms a base known as the conjugate base of an acid.

At those instants, the energy of the wave has been transformed into the potential energy of the string.

This is because, during the wave's motion, the peaks and troughs move towards equilibrium. As they move, they store energy in the form of elastic potential energy, which is the energy stored in the string due to its stretching. When the wave is totally flat, the wave has reached equilibrium and the stored energy has been converted into potential energy. This is why the string appears flat at those instants.
The energy is not transformed into the kinetic energy of the string or the energy of sound waves. The nodes of the wave, where the string is flat, are points at which the wave's kinetic energy is zero, and the energy of sound waves is not produced by standing waves.

Answer:

A)   F = - 8.5 10² N,  B)   I = 21 N s

Explanation:

A) We can solve this problem using the relationship of momentum and momentum

          I = Δp

in this case they indicate that the body rebounds, therefore the exit speed is the same in modulus, but with the opposite direction

         v₀ = 8.50 m / s

         v_f = -8.50 m / s

         F t = m v_f -m v₀

         F = \(m \frac{(v_f - v_o)}{t}\)

let's calculate

         F = \(1.00 \ \frac{(-8.5-8.5)}{2 \ 10^{-2}}\)

         F = - 8.5 10² N

B) let's start by calculating the speed with which the ball reaches the ground, let's use the kinematic relations

         v² = v₀² - 2g (y- y₀)

as the ball falls its initial velocity is zero (vo = 0) and the height upon reaching the ground is y = 0

         v = \(\sqrt{2g y_o}\)

calculate  

         v = \(\sqrt{2 \ 9.8 \ 10}\)

         v = 14 m / s

to calculate the momentum we use

         I = Δp

         I = m v_f - mv₀

when it hits the ground its speed drops to zero

we substitute

         I = 1.50 (0-14)

         I = -21 N s

the negative sign is for the momentum that the ground on the ball, the momentum of the ball on the ground is

        I = 21 N s

(a)The force that the foot applied on the ball will be 175 N.

(b)The impulse experienced by the rock during its fall will be 21 Ns.

The given data in the question will be

m is the mass of soccer ball = 1.00 kg

u is the velocity by which ball hits =5.00 m/sec

v is the velocity by which ball rebounds=8.50 m/sec.

(a) The force that the foot applied on the ball will be 175 N.

If the ball rebounds  with the the velocity of 8.50m/sec then

\(\rm F= \frac{m(v-u)}{t} \\\\\rm F= \frac{1(8.50-5.00)}{2.00\times10^{-2}}\\\\\rm F=175 N\)

Hence the force that the foot applied on the ball will be 175 N.

(b)The impulse experienced by the rock during its fall will be 21 Ns.

According to Newton's third equaton of motion.

\(\rm v^2=u^2+2gh\\\\\rm v^2=2\times9.81\times10.0\\\\\rm v=\sqrt{2\times9.81\times10.0} \\\\\rm v= 14.0071 m/sec\)

Due to the free fall condition the initial velocity is zero,

Impulse is given by the change in momentum,

I=ΔP

I=m(v-u)

\(\rm I=m(v-u)\\\\\rm I=1.50(14.0-0)\\\\\rm I=21 Ns\)

Hence the impulse experienced by the rock during its fall will be 21 Ns.

An astronaut in an orbiting shuttle experiences a sensation of weightlessness because the gravitational force is balanced by the centripetal force due to the shuttle's motion.

When an object is in orbit around the Earth, it experiences a gravitational force towards the Earth. This force is responsible for keeping the object in orbit. However, the object also experiences a centripetal force that is equal in magnitude but opposite in direction to the gravitational force. As a result, the object appears to be weightless because the gravitational force and the centripetal force cancel each other out.

In the case of an astronaut in an orbiting shuttle, the astronaut is still being pulled by the Earth's gravitational field, but the gravitational force is balanced by the centripetal force due to the shuttle's motion. This means that the astronaut experiences a sensation of weightlessness. The astronaut is not beyond the pull of gravity (option a) or shielded from the Earth's gravitational field (option c). The astronaut is also not pulled only by gravitation to the shuttle which cancels the Earth's gravitational pull (option d).

The "weightless" astronaut in an orbiting shuttle is like the shuttle, pulled by Earth's gravitation. The correct option is e.

When an astronaut is in an orbiting shuttle, they are not beyond the pull of gravity or shielded from Earth's gravitational field. The correct answer is that they are like the shuttle, pulled by Earth's gravitation.

This is because both the astronaut and the shuttle are in a state of freefall around the Earth. In orbit, the gravitational force acting on the astronaut is balanced by the centripetal force required to maintain the circular motion of the shuttle around the Earth. As a result, the astronaut experiences a sensation of weightlessness.

Although the force of gravity is still present, the astronaut and the shuttle are in a state of continuous freefall, causing them to constantly fall towards the Earth while also moving forward with sufficient speed to maintain a stable orbit.

This continuous freefall creates the feeling of weightlessness for the astronaut, as there is no contact force opposing gravity's pull. Therefore, the correct option is that the astronaut is like the shuttle, pulled by Earth's gravitation. Option e is the correct one.

Answer:

The rms voltage across the capacitor is approximately 224.926 V.

a) To find the rms current (I) in the RLC series circuit, we can use the formula:

I = V / Z

Where V is the rms potential difference provided by the source, and Z is the impedance of the circuit.

The impedance of an RLC series circuit is given by:

Z = √(R^2 + (Xl - Xc)^2)

Where R is the resistance, Xl is the inductive reactance, and Xc is the capacitive reactance.

V = 210 V

f = 250 Hz

L = 0.35 H

C = 70 uF

VR = 45 V

First, let's calculate the reactances:

Xl = 2πfL

Xc = 1 / (2πfC)

Substituting the values:

Xl = 2π * 250 * 0.35

Xc = 1 / (2π * 250 * 70e-6)

Calculating:

Xl ≈ 549.78 Ω

Xc ≈ 114.591 Ω

Next, we can calculate the impedance:

Z = √(R^2 + (Xl - Xc)^2)

Substituting the given VR value, we have:

VR = I * R

Rearranging the equation to solve for R:

R = VR / I

Substituting the given values:

45 = I * R

Solving for R:

R = 45 / I

Substituting the values of Xl and Xc into the impedance equation:

Z = √(R^2 + (549.78 - 114.591)^2)

Substituting the value of Z into the formula for rms current:

I = V / Z

Calculating:

I ≈ 1.962331945 A

Therefore, the rms current in the RLC series circuit is approximately 1.962 A.

b) The resistance (R) in the circuit can be found using the equation:

R = VR / I

Substituting the given values:

R = 45 / 1.962331945

Calculating:

R ≈ 22.943 Ω

Therefore, the resistance in the RLC series circuit is approximately 22.943 Ω.

c) The rms voltage across the inductor (VL) can be calculated using the formula:

VL = I * Xl

Substituting the values:

VL = 1.962331945 * 549.78

Calculating:

VL ≈ 1,076.644 V

Therefore, the rms voltage across the inductor is approximately 1,076.644 V.

d) The rms voltage across the capacitor (Vc) can be calculated using the formula:

Vc = I * Xc

Substituting the values:

Vc = 1.962331945 * 114.591

Calculating:

Vc ≈ 224.926 V

Therefore, the rms voltage across the capacitor is approximately 224.926 V.

If two stars have the exact same spectral class, then they must have similar temperatures, masses, and sizes. The spectral class of a star is determined by its surface temperature, which affects the colors and intensities of the electromagnetic radiation emitted by the star. This information is typically used to classify stars into seven different spectral types: O, B, A, F, G, K, and M, with O being the hottest and M being the coolest.

If a newly discovered stellar object is cooler than an M star, then it is probably a brown dwarf, a type of sub-stellar object that is too small to sustain nuclear fusion in its core. Brown dwarfs are often referred to as "failed stars" since they are too small to become full-fledged stars but too large to be classified as planets. Brown dwarfs emit very little visible light and instead radiate in the infrared part of the spectrum. They can be difficult to detect due to their low luminosity and can be identified using specialized instruments that are sensitive to infrared radiation.

In summary, the spectral class of a star provides information about its temperature, size, and mass, and stars with the same spectral class will have similar properties. A newly discovered stellar object that is cooler than an M star is likely a brown dwarf, a sub-stellar object that emits primarily in the infrared part of the spectrum.
