A completely ionized beryllium atom (net charge = +4e) is accelerated through a potential difference of 6.0 v. what is the increase in kinetic energy of the atom?
Final answer:
The increase in kinetic energy of a completely ionized beryllium atom accelerated through a potential difference of 6.0 V is +24 electron volts (eV).
Explanation:
To calculate the increase in kinetic energy of a completely ionized beryllium atom accelerated through a potential difference of 6.0 V, we need to use the formula:
ΔK = q × ΔV
Where ΔK is the increase in kinetic energy, q is the charge of the ion, and ΔV is the potential difference. In this case, the beryllium atom is completely ionized with a net charge of +4e, where e is the elementary charge. Therefore, the charge (q) is +4e.
Substituting the values, ΔK = (+4e) × (6.0 V) = +24eV
So, the increase in kinetic energy of the atom is +24 electron volts (eV).

El Sol está en promedio a 93 millones de millas de la Tierra. ¿A cuántos metros equivale esto? Expréselo usando potencias de diez.
La distancia promedio entre la Tierra y el Sol es de aproximadamente 93 millones de millas. En metros, esta distancia es de aproximadamente 1.5*10^11. Se utiliza la notación científica 1.5 × 10¹¹ metros para representar esta distancia de forma más concisa y manejable.
Explanation:El Sol está, en promedio, a 93 millones de millas de la Tierra. Sabemos que 1 milla equivale a 1.60934 kilómetros y que un kilómetro es igual a 10^3 metros. Por lo tanto, podemos decir que una milla es igual a 1.60934*10^3 metros.
Para convertir la distancia desde la Tierra hasta el Sol a metros, multiplicamos 93,000,000 millas por 1.60934*10^3 metros/milla. Esto da como resultado aproximadamente 1.5*10^11 metros. Así que, en notación científica, la distancia desde la Tierra hasta el Sol es de aproximadamente 1.5 × 10¹¹ metros.

Volume or intensity of a sound wave is measured by the size of the _________ and reported in decibels.
Answer:
Amplitude
Explanation:
The intensity (or volume) of a sound wave is proportional to the square of the sound wave:
[tex]I\propto A^2[/tex]
where A is the amplitude of the wave.
The amplitude of a sound wave is measured as the maximum displacement of the wave with respect to its equilibrium position.
The intensity is measured in Decibels (dB), which is related to the logarithmic ratio between the power of two different sounds, i.e. the difference in decibels between two sounds is given by
[tex]10 Log (\frac{P_2}{P_1})[/tex]
where P1 and P2 are the power of the two sounds.

The highest element in the hierarchical breakdown of the Work Breakdown Structure (WBS) is the project itself. This project is then divided into definable and measurable tasks or subtasks forming a hierarchical structure.
Explanation:The highest element in the hierarchical breakdown of the Work Breakdown Structure (WBS) is the project itself. WBS is a tool used in project management to divide a project into manageable chunks or portions. It begins with the final deliverable or project at the top level. This is subsequently broken down into definable and measurable tasks or subtasks forming a multi-level structure. A good example could be a software development project. The entire project would be the highest element and might be divided into phases like planning, design, coding, testing, and implementation. Each of these could be further broken down into more specific tasks.

what type of simple machine is a catapult?( incline plane , lever , pulley , screw , wedge, or a wheel and axle) How do you know ?
Answer: Lever
Explanation:
A catapult as a machine is a lever (1st class) because the fulcrum is between the Effort applied and the load(object) to be launched. A first class lever machine is a machine that has the fulcrum in between the effort and the load which makes a catapult a first class lever.
The handle of the catapult is where the effort is applied, the fulcrum is the point of contact between the rubber tied to the stick and the stick itself and the load is the object to be launched.
A catapult is a type of lever because it uses a rigid arm that pivots around a fixed point to launch a projectile.
A simple machine known as a lever is made up of a rigid bar or board that pivots around a fixed point, also known as a fulcrum. The fulcrum of a catapult is the location where the weapon's arm is joined to the base.
Potential energy is stored in the system when the catapult's arm is retracted. Potential energy is transformed into kinetic energy when the arm is released, which causes the arm to swing forward and fire the projectile.
Seesaws, scissors, and crowbars are a few examples of machines that utilize the lever concept. The lever enables the application of a little force over a longer distance to produce a bigger force over a shorter distance.
Therefore, a catapult is a type of lever. The correct answer is lever. An example of a lever is a catapult.

A car slows down from 27.7 m/s to 10.9 m/s in 2.37s. What is the acceleration?
A car slows down from 27.7 m/s to 10.9 m/s in 2.37s.Then the acceleration is -7.09 m/sec².
What is acceleration ?Acceleration is the rate at which an object's velocity with respect to time changes. They are vector quantities, accelerations. The direction of the net force acting on an object determines the direction of its acceleration.
An object has positive acceleration if it is accelerating and travelling in the right direction. Positive acceleration was demonstrated in the first example by the speeding car. The acceleration is occurring in the same direction as the car's motion, which is forward and speeding up.
The equation a = v/t denotes acceleration (a), which is the change in velocity (v) over the change in time (t).
The final velocity 'v' =10.9 m/s
The time 't' = 2.37 secs.
Then acceleration = -7.09 m/sec² or, decceleration is 7.09 m/sec².
Thus, the acceleration is -7.09 m/sec².
