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.

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.

= 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

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

= d

= 6 * (30÷6)² / 2

Answer:

Explanation:

The formula for kinetic energy is:

KE = (1/2) * m * v^2

where KE is kinetic energy, m is mass, and v is velocity.

We are given KE = 4.33 × 10³ J and v = 23 m/s.

Plugging these values into the formula, we get:

4.33 × 10³ J = (1/2) * m * (23 m/s)^2

Simplifying and solving for m, we get:

m = 4.33 × 10³ J / [(1/2) * (23 m/s)^2]

m = 4.33 × 10³ J / (0.5 * 529 m^2/s^2)

m = 4.33 × 10³ J / 264.5 J/(kg·m^2/s^2)

m = 16.37 kg

Therefore, the mass of the car is approximately 16.37 kg.

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:

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":

The force exerted on a charged particle in a magnetic field is given by the equation:

F = q * v * B

where q is the charge of the particle, v is its velocity, and B is the magnetic field.

Since an electron has a charge of -1.6 x 10^-19 C, the magnitude of the force exerted on it by the magnetic field is:

F = q * v * B = -1.6 x 10^-19 C * v * B

To find the velocity of the electron, we can use the equation for the work

done by an electric field on a charged particle:

W = q * V

where W is the work done, q is the charge of the particle, and V is the potential difference.

Since the work done is equal to the change in kinetic energy of the particle, we have:

W = (1/2) * m * v^2, where m is the mass of the electron

So,

q * V = (1/2) * m * v^2

Solving for v, we get:

v = sqrt(2 * q * V / m)

v = sqrt(2 * -1.6 x 10^-19 C * 100 V / 9.11 x 10^-31 kg) = 5.9 x 10^6 m/s

The directional speed of an item in motion, as measured by a specific unit of time and observed from a certain point of reference, is what is referred to as velocity.

How to define velocity?

It will take the trout 2.8 minutes to reach the boat.

Use the following formula to solve for the time it takes the trout to reach the boat:

time = distance/velocity

distance = 9,800 centimeters (the starting distance between the trout and the boat)

velocity = 3,500 centimeters per minute (the velocity of the trout swimming toward the boat)

put in the values:

time = 9,800 / 3,500

time = 2.8 minutes

So, it will take the trout 2.8 minutes to reach the boat.

The directional speed of an item in motion, as measured by a specific unit of time and observed from a certain point of reference, is what is referred to as velocity. Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is traveling along a path. In other words, velocity is a vector, whereas speed is a scalar value. Since it is a vector quantity, the definition of velocity requires both magnitude (speed) and direction.

We can say that forces produce changes in velocity because they alter an object's speed or direction. Keep in mind that acceleration is a modification of velocity.

Answer:

Explanation:

The collision between the 93kg fullback and the 127kg defensive tackle is an example of an inelastic collision. In an inelastic collision, the total kinetic energy of the system is not conserved as some of the energy is transformed into other forms such as heat or sound. The resulting final speed of both players would be 0m/s, indicating that they have come to a stop after the collision.
