which type of photon is emitted when an electron in a hydrogen atom drops from the n=2 to the n=1

Answers

Answer 1

An ultraviolet type of photon is released whenever an electron inside a hydrogen atom transitions from the n-2 to the n-1 energy level.

An electron is a negatively charged neutron star that can be either free or bonded to an atom (not bound). An atom has three basic types of particles: protons, neutrons, and the electron that is connected to them.

The electrons are an atom's negatively charged building blocks. A negatively charged atom is created when all of an atom's electrons come together to balance off the positive charge that protons have inside the atomic nucleus. Electrons are the most abundant element in the universe.

Which ion in the ground state has the same electron configuration as an atom of neon in the ground state.

Answers

Na+ ion in the ground state has the same electron configuration as an atom of neon in the ground state.

The electronic configuration has been defined as the electron address in a atom. The electronic configuration has been based on the quantum rule for the filling of the electrons.

Neon is the tenth element with a total of 10 electrons. In writing the electron configuration for neon the first two electrons will go in the 2p orbital. Since 1s can only hold two electrons for Ne go in the 2s orbital. The remaining six electrons will go in the 2p orbital. Therefore, the Ne electron configuration 1s22s22p6.

Ne (atomic number=10) have 2,8 electron configurations. Here the atomic number of Na is 11. The configuration of Na is 2,8,1. Atomic number of Na+ is 10 and it has an electron configuration of 2,8 which is similar to Ne. Na+ ion is a positively charged particles, because they are missing one electron.

15-28 a type of cuckoo clock keeps time by having a mass bouncing on a spring, usually something cute like a cherub in a chair. what spring constant is needed to produce a period of 0.500 s for a 0.0150-kg mass?

Answers

Spring constant is needed to produce a period of 0.500 s for a 0.0150-kg mass: The required spring constant is 2.368.

What is the time period of a spring-mass system?

The time period of a spring-mass system is the amount of time it takes for the system to complete one full cycle of oscillation. This time period is determined by the system's spring constant and mass, and is calculated using the formula: T = 2π√(m/k), where m is the mass of the system and k is the spring constant. In a spring-mass system, the time period is typically short and can range from a few microseconds to several seconds. The time period of a spring-mass system is an important factor when designing a system, as it can affect the performance of the system. If a system is required to complete multiple cycles of oscillation within a given amount of time, then the time period must be short enough to accommodate this.

T = 2π√(m/K)

In the given problem,

Time period , T = 0.5 s

Mass, m = 0.0150-kg

T = 2π√(m/K)

K = 4π²m/T²

   = 4× π² × 0.015  /  0.5²

   = 0.592/0.25

Explanation:

A room was lighted with three 100-watt bulbs for 5 hours per day. If the cost of
electricity was 9¢ per kWh, how much would be saved per day by switching to
60-watt bulbs?

Answers

To find the amount of electricity used by the 100-watt bulbs, we need to first calculate the total wattage of the bulbs by multiplying the wattage of each bulb by the number of bulbs: 100 watts/bulb * 3 bulbs = 300 watts

Next, we need to convert the time the bulbs were used from hours to seconds. Since there are 3600 seconds in an hour, the bulbs were used for 5 hours * 3600 seconds/hour = 18000 seconds.

Now we can calculate the total amount of electricity used by the 100-watt bulbs by multiplying the wattage of the bulbs by the time they were used: 300 watts * 18000 seconds = 5.4 x 10^7 joules

To convert this to kilowatt-hours, we need to divide by the number of joules in a kilowatt-hour, which is 3.6 x 10^6. This gives us a total of 1.5 kWh.

At a cost of 9¢ per kWh, the cost of using the 100-watt bulbs for 5 hours per day is 1.5 kWh * $0.09/kWh = $0.135 per day.

To find the amount of money that would be saved by switching to 60-watt bulbs, we need to repeat the above calculation using the wattage of the 60-watt bulbs instead of the 100-watt bulbs. The total wattage of the 60-watt bulbs is 60 watts/bulb * 3 bulbs = 180 watts. This means that the total amount of electricity used by the 60-watt bulbs would be 180 watts * 18000 seconds = 3.24 x 10^7 joules, or 0.9 kWh.

At a cost of 9¢ per kWh, the cost of using the 60-watt bulbs for 5 hours per day is 0.9 kWh * $0.09/kWh = $0.081 per day.

Therefore, the amount of money that would be saved by switching to 60-watt bulbs is $0.135 per day - $0.081 per day = $0.054 per day.

Answer:

The height of the hill coasted by a skier of initial velocity 12 m/s is 2.5 m. And The correct option is C 2.5 m.

The high of the hill is 2.5 m

What is conservation of energy?

It states that energy can neither be created nor be destroyed.

Mass of skier,m  = 60kg

initial velocity, u = 12 m/s

Final velocity, v = 9.75 m/s

As there is no friction, energy is conserved

∴ Initial kinetic energy +  Initial potential energy = Final kinetic energy + Final potential energy

1/2 mu² + 0  = 1/2m v² + mgh

1/2 u² = 1/2 v² + gh

h = u² - v² /2g

Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is travelling along a path. In other words, velocity is a vector, whereas speed is a scalar value.

Calculation:

Varying frequency of the siren = 564 Hz to 376 Hz

speed of sound = 343 m/s

speed of truck calculation

using equation of Doppler's

When the truck is approaching

Fs = F₀(v - vs)/v......(i)

Doppler's equation when truck is moving away

Fs = F₁(v + vs)/v ......(ii)

equating both the equation

Fs = F₀(v - vs)/v = Fs = F₁(v + vs)/v

Vs = v(F₀ - F₁)/F₀ + F₁)

F₀ = 564Hz

friction usually acts to oppose, or slow down, the velocity of objects. which situation is an example of friction causing an increase in velocity?

Answers

There are certain situations where friction can cause an increase in velocity. One such situation is when an object is sliding down a hill or incline.

In this case, the force of gravity is pulling the object down the incline, and the force of friction is acting against this motion, pushing up against the object. However, because the incline is angled downward, the force of friction is actually able to provide an upward acceleration to the object, causing it to increase in velocity as it moves down the hill.

Another situation where friction can cause an increase in velocity is when an object is sliding along a flat surface and a force is applied to it in the direction of motion. In this case, the friction between the object and the surface can provide an additional force that helps to accelerate the object.

Friction usually acts to oppose the motion of objects, slowing them down or bringing them to a stop. It's important to note that these situations are relatively rare, and in most cases, friction will act to oppose the motion of objects and slow them down.

Answers

A 10-kg piece of aluminum sits at the bottom of a pool, right next to a 10-kg piece of lead.  Aluminum has greater buoyant force acting on it.

Density is defined as mass per unit volume:

ρ = m /V

Where:

m = mass

V = volume

The lead is much denser than aluminum. Their densities are:

ρ_Al = 2.7 g/cm³

ρ_Pb = 11.29 g/cm³    (Pb is the symbol for lead)

From the equation, if the masses are the same, the density is inversely proportional to the volume.

In the given problem, since lead is denser than aluminum, hence, the volume of aluminum is greater than the volume of lead.

The buoyant force is equal to the weight of displaced water.

For each piece of metal, it holds

F = ρ_water x g x V_metal

Hence, the buoyant force is directly proportional to the volume of each piece of metal.

Since V_Al > V_Pb, then  F_Al > F_Pb or Aluminum will experience greater buoyant force.
