if a world-class sprinter ran a distance of 100 m starting at his top speed of 8 m/s and running with constant speed throughout, how long would it take him to cover the distance?

1180.7 meters far the tuning fork has fallen when waves of frequency 657 Hz reach the release point while taking the speed of sound in air to be 343 m/s.

We can determine the distance fallen by the tuning fork by considering the time it takes for the waves of frequency 657 Hz to reach the release point. We know that the speed of sound in air is 343 m/s, so the distance traveled by the sound waves is equal to the speed of sound multiplied by the time elapsed.

Let "d" be the distance fallen by the tuning fork and "t" be the time elapsed. The frequency of the tuning fork changes due to its motion under the influence of gravity, and this change in frequency is related to the distance fallen:

= f

= [tex]683 Hz \sqrt{*[1 - (d * g) / (343 m/s)^2]}[/tex]

here, "g" is the acceleration due to gravity.

Setting this expression equal to 657 Hz and solving for "d":

= 657 Hz

= [tex]683 Hz * \sqrt{[1 - (d * g) / (343 m/s)^2]}[/tex]

Solving for "d":

= d

= [tex](343 m/s)^2 * [1 - (657 Hz / 683 Hz)^2] / g[/tex]

adding the values:-

= d

= [tex](343 m/s)^2 * [1 - (657 Hz / 683 Hz)^2] / 9.80 m/s^2[/tex]

= [tex](343 m/s)^2 * [1 - (657 Hz / 683 Hz)^2] / 9.80 m/s^2[/tex]

= [tex](119056 m^2/s^2) * [1 - (657 Hz / 683 Hz)^2] / 9.80 m/s^2[/tex]

= [tex](12149.6 m^2/s^2) * [1 - (657 Hz / 683 Hz)^2] / 9.80 m/s^2[/tex]

= [tex](12149.6 m^2/s^2) * (1 - (657 Hz / 683 Hz)^2) / 9.80 m/s^2[/tex]

= [tex]12149.6 * [1 - (657 Hz / 683 Hz)^2] / 9.80 m[/tex]

= [tex]12149.6 * [1 - (657 Hz ÷ 683 Hz)^2] / 9.80 m[/tex]

= [tex]12149.6 * (1 - 0.0384) / 9.80 m[/tex]

= [tex]12149.6 * 0.9616 / 9.80 m[/tex]

= 1180.7 m

Therefore, the tuning fork has fallen a distance of 1180.7 m when waves of frequency 657 Hz reach the release point.

A 30 m/s fast automobile is spotted by a police officer as it travel. The police officer will have to drive a distance of 450 meters to catch up to the speedy car.

To determine the distance the police officer must drive to catch up to the speeding car, we can use the concept of relative velocity. The relative velocity of the police officer with respect to the speeding car while its travel is given by:

= v rel.

= [tex]v_o_f_f_i_c_e_r - v_s_p_e_e_d_e_r[/tex]

here,

v officer is the velocity of the police officer

v speeder is the velocity of the speeding car.

Since, the police officer is accelerating, we need to determine the velocity of the police officer as a function of time.

= v officer

= a * t

here,

a is the acceleration of the police officer

t is the time elapsed since the officer started driving.

We want to find the time t when the relative velocity is zero, meaning that the police officer has caught up to the speedy car.

= 0

= a * t - v speeder

Solving for t:

= t

= [tex]v_s_p_e_e_d_e_r / a[/tex]

Now that we have the time t,

= d

= [tex]v_o_f_f_i_c_e_r * t[/tex]

= [tex]a * t^2 / 2[/tex]

Replacing t from the previous equation:

= d

= [tex]a * (v_s_p_e_e_d_e_r / a)^2 / 2[/tex]

Replacing the values of

=> a = 6 m/s²

=> [tex]v_s_p_e_e_d_e_r[/tex] = 30 m/s:-

= d

= 6 * (30÷6)² / 2

Answer: Yes

Explanation: It has space in its valence shell for an additional electron.

The answer to this question is yes, a neutral hydrogen atom does have an attraction for an additional electron. This attraction arises from the fact that the positively charged proton in the nucleus of the atom attracts negatively charged electrons. When an additional electron is brought near the hydrogen atom, it will be attracted to the positively charged proton in the nucleus. The attraction between the proton and the electron is quantified by Coulomb's law.

Neutral hydrogen atoms consist of a single proton in the nucleus and a single electron in the outer shell. The electron is negatively charged, while the proton is positively charged. Thus, the electron and the proton are attracted to each other by the electromagnetic force, creating a stable neutral atom. The question asks whether the neutral hydrogen atom has an attraction for an additional electron.

Coulomb's law states that the force between two charged particles is proportional to the product of their charges and inversely proportional to the distance between them. In the case of the hydrogen atom, the force between the electron and the proton is given by:

F = kq1q2/r^2

where F is the force, k is Coulomb's constant, q1 is the charge of the electron, q2 is the charge of the proton, and r is the distance between them.

Since the electron has a negative charge and the proton has a positive charge, their product (q1q2) is negative, which means the force between them is attractive. As the distance between the electron and the proton decreases, the force between them increases. Therefore, when an additional electron is brought near the hydrogen atom, it will be attracted to the positively charged proton in the nucleus.

However, there is a limit to how many electrons can be added to a hydrogen atom. When a second electron is added, it will be repelled by the first electron, and the repulsive force between the two electrons will become stronger than the attractive force between the electron and the proton. This means that adding a second electron to a hydrogen atom requires more energy than adding the first electron. In fact, the energy required to add a second electron is so high that it is unlikely to occur under normal conditions. Therefore, a neutral hydrogen atom can attract an additional electron, but it can only form a negative ion with a single additional electron.

Fermat's theorem, also known as the principle of least time, states that the path taken by light or any other wave between two points is the path that minimizes the time taken. In fluid dynamics, this theorem can be applied to the flow of fluids in pipes or channels.

The basic idea is that the fluid will take the path that minimizes the time it takes for it to travel from one point to another. In other words, the fluid will follow the path of least resistance, where resistance is determined by the fluid's velocity and the diameter of the pipe or channel.

For example, in a fluid flow system with multiple branches or turns, the fluid will tend to follow the path with the smallest diameter or the least amount of resistance, as this will be the quickest path for the fluid to take.

This can be important in designing fluid systems, as it can affect the flow rate, pressure, and energy consumption of the system.

In summary, the correct application of Fermat's theorem to fluid dynamics involves considering the time it takes for a fluid to travel from one point to another and selecting the path that minimizes that time. This can help in optimizing fluid flow systems and improving their efficiency.

Two points or particles that are "corresponding points" are those that have finished the same fractions of their periodic motion and are in the same phase. Ordinarily, the wavelength of transverse waves—those with points vibrating perpendicular to the direction of their advance—is calculated from crest to crest or from trough to trough; for longitudinal waves—those with points vibrating parallel to the direction of their advance—the wavelength is calculated from compression to compression or from rarefaction to rarefaction.

#SPJ4

Answer with Explanation:

We can use the formula for acceleration to find the train's acceleration:

acceleration = (final velocity - initial velocity) / time

In this case, the initial velocity of the train is 60 m/s (since that's how fast it was going before it hit the brakes), the final velocity is 0 m/s (since the train comes to a complete stop), and the time it takes for the train to stop is 1 minute and 40 seconds, or 100 seconds.

So, plugging in the values we have:

acceleration = (0 m/s - 60 m/s) / 100 s

acceleration = -60 m/s / 100 s

acceleration = -0.6 m/s^2

Note that the negative sign indicates that the train is decelerating (slowing down), as opposed to accelerating (speeding up).

Wavelength is a physical property of some energies that corresponds to the distance between wave peaks (characteristics of light waves, distance between the peaks of consecutive waves).

The amplitude and wavelength of a wave are two physical properties. Measured from the wave's highest point (peak or crest) to its lowest point, the amplitude of a wave indicates its height (trough). Wavelength is the distance a wave travels between peaks.

A waveform signal that is carried in space or down a wire has a wavelength, which is the separation between two identical places (adjacent crests) in the consecutive cycles. This length is typically defined in wireless systems in meters (m), centimeters (cm), or millimeters (mm) (mm). The wavelength is more frequently described in nanometers (nm), which are units of 10-⁹ m, or angstroms (Å), which are units of 10-¹⁰ m, for infrared (IR), visible light (UV), and gamma radiation (γ)

The stunt driver must drive off the ramp with a minimum speed of 53.93 m/s to successfully clear the 10 parked cars.

The trick driver needs to get an upward level free from 2.0 m and a flat distance of 24 m. To find the base speed required, we can involve the kinematic condition for vertical movement affected by gravity:

vf^2 = vi^2 + 2 * g * Δy

where vf is the last speed (extent of speed), vi is the underlying speed (size of speed), g is the speed increase because of gravity (9.8 m/s^2), and Δy is the adjustment of vertical level. We need the underlying speed (vi) so we can rework the condition:

vi = √(vf^2 - 2 * g * Δy)

For this situation, Δy = 2.0 m, g = 9.8 m/s^2, and vf = 0 (last speed is 0 in light of the fact that the vehicle lands on the ground).

vi = √(0 - 2 * 9.8 * 2.0) = √(- 39.2) = 6.27 m/s

This is the base vertical speed the vehicle should need to clear the 10 left vehicles. To find the base speed, we should likewise consider the even speed expected to cover the distance of 24 m.

v = √(vi^2 + vh^2)

where vh is the even speed. Since the even distance is 24 m and the hour of flight can be determined utilizing the upward movement condition, we can utilize the condition:

vh = d/t

where d is the flat distance (24 m) and t is the hour of flight.

t = √((2 * Δy)/g) = √((2 * 2.0)/9.8) = 0.447 s

vh = 24 m/0.447 s = 53.67 m/s

At long last, the base speed can be found as:

v = √(vi^2 + vh^2) = √(6.27^2 + 53.67^2) = 53.93 m/s (adjusted to 2 critical digits)

In this way, the trick driver should drive off the slope with a base speed of 53.93 m/s to clear the 10 left vehicles effectively.
