Inspiratory reserve volume is the additional amount of air that can be inhaled at the end of quiet inspiration.

Inhalation : The act of drawing air into the lungs during inspiration, also known as inhalation.

By establishing a pressure differential between the lungs and the atmosphere, it is accomplished.

The diaphragm contracts toward the abdominal cavity as air enters the lungs, creating more room in the thoracic cavity for the air to fit.

Inspiratory reserve volume is the additional volume of air that can be maximally inspired after finishing a typical, quiet inspiration.

Or the volume of air that can be inhaled following a regular breath is known as the inspiratory reserve volume.

It is denoted by IRV.

In men average IRV is 3.3 L whereas in women it is about 1.9 L

Hence, Inspiratory reserve volume is the additional amount of air that can be inhaled at the end of quiet inspiration.

Answer:

Answer:That only applies to highly polished surfaces, eg mirrors.

If you take a high quality laser (ie with low divergence) and aim it at a wall, you can see the spot where the laser beam reaches the wall from anywhere with a direct line-of-sight to the spot where the laser beam reaches the wall. This due to micro imperfections on the surface of the wall. At a microscopic level, the wall surface is very rough and pointing in all directions.

As to why, a beam of light bounces of a highly polished surface, I can only surmise that it is essentially due to kinematics, ie the only force opposing the light beam is normal to the surface, hence there no forces along the reflective surface. Since there are no forces along the reflective surface, the speed component of light along the reflective surface remains unchanged. However, on the plane perpendicular to the reflective surface the, the light photons bounce off at the same speed at which the hit the reflective surface because the mass of the reflective surface is much much much larger than the mass of the photons, which means that the reflective surface won’t move at all. Since conservation of momentum requires that momentum after the collision be the same as the momentum before the collision then the only way for that to happen is if the velocity of the photon perpendicular to the reflective surface is of exactly the same magnitude but in the opposite direction. Vector resolution of the speed component of the reflected beam means that the angle of reflection must be the same as the angle of incidence.

Gravitational potential energy is the maximum at point C and lowest at point A

Explanation:

The image for the question is provide in the attached file

The energy of pendulum is governed by mechanical energy. Mechanical energy is the sum of potential energy and kinetic energy

Potential energy increases with increasing height. Thus, when the pendulum bob is at maximum height, then its potential energy is also the highest.

Thus, At point C, the gravitational potential energy is the highest

At point A, the  gravitational potential energy  is substantial but lower than that of gravitational potential energy at point C

AT point A, gravitational energy is the lowest

The minimum and maximum braking distances needed to ensure that all vehicles traveling at the posted speed limit can stop before reaching the intersection are as follows:

- For small cars: Minimum ≈ 1773.028 m, Maximum ≈ 1568.850 m

- For large trucks: Minimum ≈ 3285.760 m, Maximum ≈ 2409.595 m

To calculate the minimum and maximum braking distances, we can use the equations of motion for a decelerating vehicle.

The equation for the braking distance of a vehicle is given by:

d = (v^2) / (2 * μ * g)

where d is the braking distance, v is the initial velocity of the vehicle, μ is the coefficient of friction between the tires and the road, and g is the acceleration due to gravity.

Let's calculate the minimum and maximum braking distances separately for small cars and large trucks.

For small cars with a mass of 563 kg:

- Minimum braking distance:

  v = 8989 km/h = (8989 * 1000) / 3600 m/s = 2496.944 m/s

  μ_min = 0.536

  d_min = (v^2) / (2 * μ_min * g) = (2496.944^2) / (2 * 0.536 * 9.8) ≈ 1773.028 m

  Maximum braking distance:

  μ_max = 0.599

  \(d_max = (v^2) / (2 * μ_max * g) = (2496.944^2) / (2 * 0.599 * 9.8) ≈ 1568.850 m\)

For large trucks with a mass of 3951395 kg:

- Minimum braking distance:

  v = 8989 km/h = 2496.944 m/s (same as for small cars)

  μ_min = 0.350

 \(d_min = (v^2) / (2 * μ_min * g) = (2496.944^2) / (2 * 0.350 * 9.8) ≈ 3285.760 m\)

  Maximum braking distance:

  μ_max = 0.480

 \(d_max = (v^2) / (2 * μ_max * g) = (2496.944^2) / (2 * 0.480 * 9.8) ≈ 2409.595 m\)

this problem assume that both of whale and submarine are in rest position or in constant linier motion in same direction and same speed.

The sound will travel from Submarine to the whale and back again to submarine. so the time will be like this

t = 2d/v

t = 2*58.8/1520

t = 117.6/1520

t = 0.077368 s

t ≈ 0.08 s (less then 1 s)

Answer:

0.0774s

Explanation:

The formula to find the time of an echo is time = (2)(distance) / (velocity)

So plug in the numbers to the formula

= 0.0774s

Answer:

First of all, what is acceleration? — Acceleration is the rate of change of velocity per unit of time.

Now, we know that velocity is a vector quantity i.e we need both magnitude and direction to define it and so is acceleration. We can now say that in acceleration, the direction of motion is very important or to define acceleration we need both the magnitude of motion (here it is the speed) and its direction.

Now coming to your question. There are two possible answers to this question.

,Case 2 — When the body is not moving in a straight line or is constantly changing its direction. In this cas the speed still is constant but the direction is constantly changing, for example in the case of a circular motion the direction of motion constantly changes (the direction of a moving body in a circular path at any point is the direction of the tangent of the circle at that point). Hence the velocity changes as the body move along the circular or curved path.

Now, as  I earlier mentioned to define acceleration we need to know it's magnitude and it's direction, and acceleration is the rate of change of velocity per unit of time — the speed remaining constant the direction constantly changing, and the velocity changes at different time intervals or rate of change of velocity is ≠ 0 unlike in case 1. Since there is the of and a change in velocity (speed constant but the direction is changing) there is some acceleration.

To sum everything up — in the case of linear motion i.e motion in a straight line when the speed is constant and direction is not changing, velocity will be zero and hence acceleration would be zero. In case of a non-linear motion i.e motion not in a straight line, in a circle or any path where the speed is constant but the direction is constantly changing, velocity will not be zero and hence the acceleration would not be equal to zero. Either it would be greater or less than zero.

According to the given statement , the acceleration of the sphere at the instant when its speed is 27.0 m/s.

We can use the principles of electrostatics and kinematics.  a = [(9.00 x 10⁹ N * m² / C²) * |5.00 μC * 2.00 μC| / (0.08 m)²] / (4.00 x 10⁻³ kg).

1. Determine the electric force between the two charges:
  - The electric force between two charges can be calculated using Coulomb's Law:

F = k * |q1 * q2| / r².
  - In this case, q1 = 5.00 μC and q2 = +2.00 μC. The distance between them, r, is the horizontal distance of 8.00 cm (which is 0.08 m).
  - The constant k is 9.00 x 10⁹ N * m^2 / C².
  - Plugging in the values, we get F = (9.00 x 10^9 N * m² / C²) * |5.00 μC * 2.00 μC| / (0.08 m)².

2. Calculate the net force acting on the sphere:
  - At any instant, the net force acting on the sphere is the sum of the electric force and the force due to gravity.
  - However, in this case, gravity can be neglected, as stated in the question.
  - Therefore, the net force acting on the sphere is equal to the electric force between the two charges.

3. Calculate the mass of the sphere:
  - The mass of the sphere is given as 4.00 x 10⁻³ kg.

4. Apply Newton's second law:
  - Newton's second law states that the net force acting on an object is equal to the product of its mass and acceleration: Fnet = m * a.
  - In this case, the net force acting on the sphere is the electric force between the charges.
  - Plugging in the values, we get (9.00 x 10⁹ N * m^2 / C²) * |5.00 μC * 2.00 μC| / (0.08 m)² = (4.00 x 10⁻³ kg) * a.

5. Solve for the acceleration:
  - Rearranging the equation, we have a = [(9.00 x 10⁹ N * m² / C²) * |5.00 μC * 2.00 μC| / (0.08 m)²] / (4.00 x 10⁻³ kg).
  - Evaluating the expression, we find the value of acceleration.

By following these steps, you can find the acceleration of the sphere at the instant when its speed is 27.0 m/s.

Answer:

With more particles there will be more collisions and so a greater pressure. The number of particles is proportional to pressure, if the volume of the container and the temperature remain constant. ... This happens when the temperature is increased.

Explanation:

Assuming the gas to be an ideal gas, the temperature will increase at the same rate as the pressure increases.

Let us assume that the gas in the container is an ideal gas. Then from the ideal gas equation, we get that:

PV = nRT

where P is the pressure of the gas

V is the volume

T is the temperature

n is the number of moles of the gas

R  is the universal gas constant

Now, it is given that V is constant, R is already a constant, and n will also be constant, since the number of moles of gas in the container is not changing, so:

P = nRT/V

P = constant × T

P/T = constant

This means that the temperature will increase at the same rate as the pressure increases.

(A) The Flix takes 1.5 seconds to reach his top speed of 4 m/s. (B) Flix moved a distance of 3.75 meters while he was accelerating.

To solve this problem, we can use the equations of motion to calculate the time and distance traveled by Flix the cat.

To determine the time it takes for Flix to accelerate, we can use the equation;

v = u + at

Where;

v = final velocity (4 m/s)

u = initial velocity (1 m/s)

a = acceleration (2 m/s²)

t = time

Rearranging the equation, we have;

t = (v - u) / a

Substituting the given values;

t = (4 m/s - 1 m/s) / 2 m/s²

t = 3 m/s / 2 m/s²

t = 1.5 s

Therefore, Flix takes 1.5 seconds to reach his top speed of 4 m/s.

To determine the distance traveled while accelerating, we can use the equation;

s = ut + (1/2)at²

Where;

s = distance traveled

u = initial velocity (1 m/s)

t = time (1.5 s)

a = acceleration (2 m/s²)

Substituting the given values:

s = (1 m/s)(1.5 s) + (1/2)(2 m/s²)(1.5 s)²

s = 1.5 m + (1/2)(2 m/s²)(2.25 s²)

s = 1.5 m + (2 m/s²)(1.125 s²)

s = 1.5 m + 2.25 m

s = 3.75 m

Assuming a constant rate of Earth's rotation and neglecting any axial tilt effects, Rigel, a star, would rise approximately 4 minutes earlier each day. Therefore, if Rigel rises at 6 PM today, it would rise at around 5:56 PM tomorrow. In one month, comprising roughly 30 days, Rigel would rise approximately 2 hours earlier, at around 4 PM. These calculations are based on the assumption that the observer's location on Earth remains constant, and no other factors, such as atmospheric conditions or the star's own motion, significantly affect the timing of Rigel's rise.

The Earth rotates approximately once every 24 hours, causing the stars to appear to rise and set each day. This rotation rate is relatively constant over short timescales. Therefore, if a star rises at a specific time on a given day, it will rise approximately 4 minutes earlier the following day, as 24 hours divided by 60 minutes gives an average of 4 minutes per minute of Earth rotation. Multiplying this by the number of days in a month (30) results in approximately 2 hours earlier for the star's rise time.
