Electromagnetic radiation has a spectrum with varying wavelengths and frequencies, which gives it different properties.
Electromagnetic radiation is a type of energy that travels in packets of energy called photons as both electrical and magnetic waves.
Wave-particle duality is the name given to this phenomenon. This is a notion that defines how a wave behaves whether it behaves like particles, waves, or both particles and waves.

A 24 volt battery is connected to a circuit with a 4- light bulbs that are connected in series. Resistance of each light bulb is 3 Ohms, a) What will be the current in the circuit
Answer:
Current = 2 amps
Explanation:
Remark
The voltage of the circuit is 24 volts.
The Resistance Series circuit is
Rt = B1 + B2 + B3 + B4B1 = B2 = B3 = B4 = 3 ohmsRt = 4*3 ohms = 12 ohms (each bulb has a resistance of 3 ohms each and there are four of them)Givens
E = 24 volts
R = 12 ohms
Formula
E = I * R where
E = voltageR = resistanceI = CurrentSolution
24 volts = 12 * I Divide by 12
24/12 = I
I = 2 amperes.

Which event is part of a covection current in the air?
Answer:
As you must know, Convection Current is the transfer of heat by actual movement of molecules from a hot to cold place due to difference in densities. Thus, the phenomenon of convection current is also observed in nature, for example the Land and Sea Breezes help in keeping the temperature moderate in coastal areas. Convection current in air also helps the birds and gliders to stay in air for a long period.

What must have been the velocity of a 250 kg car that has 18000 J of energy?
Answer:
12 m/s
Explanation:
Given,
Kinetic energy ( K.E ) = 18000 J
Mass ( m ) = 250 kg
To find : Velocity ( v )
Formula : -
K.E = mv²/2
v² = 2 K.E / m
= 2 x 18000 / 250
= 2 x 72
= 144
= 12 x 12
v² = 12²
v = 12 m/s
Therefore,
the velocity of the car is 12 m/s

2. A ray of light shines from the Sun. Typically, it takes a little over 8 minutes to get from the Sun
to Earth. How much time (in seconds) would it take light to get from the Sun to the Earth (a
distance of 1.49 x 101^1 m) if we fill that space with Jello which has an index of refraction of 1.56?
Answer:
774.8 secs
Explanation:
distance(d)= speed(v)* time(t)
calculate speed:
refractive index = speed of light (c)/ speed of light in medium (v)
1.56 = 3*10^8*v
v=192307692.3 m/s
d = v *t
t = d/v
on substituting values:
t = 774.8 secs
A 70kg bicyclist (including the bicycle) is pedaling right with a constant speed despite
experiencing a 50N drag. Neglect any friction impeding her motion.
What is the magnitude of the net force on the bicyclist?
How much force is her pedaling generating?
Answer:There are total four forces acting on the bicyclist namely, gravitational force, normal force, pushing force and air drag.
The magnitude of net force acting on the bicyclist is 165 N.
The required magnitude of force generated for the pedaling is of 225 N.
Given data:
The mass of bicyclist is, m = 75.0 kg.
The magnitude of acceleration is, .
The magnitude of drag force is, F = 60.0 N.
(1)
There are in total 4 forces acting on the bicyclist:
The gravitational force on the bicyclist, acting vertically downward, of magnitude , where m is the mass of the bicyclist and g is the acceleration due to gravityThe normal force exerted by the floor on the bicyclist and the bike, N, vertically upward, and of same magnitude as the gravitational forceThe force of push F", acting horizontally forward, given by the push exerted by the bicyclist on the pedalsThe air drag, F, of magnitude F = 60.0 N, acting horizontally backward, in the direction opposite to the motion of the bicyclist
(2)
The magnitude of net force acting on the bicyclist is given as,
Thus, the magnitude of net force acting on the bicyclist is 165 N.
(3)
We need to find the forward force of push, F'', which is actually the force generated during pedaling.
Then the expression for the forward pushing force F" is given as,
Thus, we can conclude that the force generated for the pedaling is of 225 N.
Explanation:
The magnitude of the net force on the bicyclist was 0 N.
Her pedaling is generating a force of 50 N in opposite of the drag force .
What is force?Force is defined in physics as: the push or pull on an object with mass that causes it to change velocity. Force is an external agent that can change the state of rest or motion of a body. It has a magnitude as well as a direction.
A spring balance can be used to calculate force.
As the bicyclist (including the bicycle) is pedaling right with a constant speed, the magnitude of the net force on the bicyclist was = mass × acceleration
= 70 kg × 0 m/s²
= 0 N.
Again her pedaling is generating a force = drag force = 50 N in opposite of the drag force . So that, net force on it becomes zero.

Which transition by an electron will release the greatest amount of energy? a b c d
The electron of orbital a by transition will release the greatest amount of energy.
What is transition energy?Atomic electron transition is a change (or jump) of an electron from one energy level to another within an atom or artificial atom.
It appears discontinuous as the electron "jumps" from one quantized energy level to another, typically in a few nanoseconds or less.
It is also known as an electronic (de-)excitation or atomic transition or quantum jump.
Electron transitions cause the emission or absorption of electromagnetic radiation in the form of quantized units called photons. Their statistics are Poissonian, and the time between jumps is exponentially distributed.
The damping time constant (which ranges from nanoseconds to a few seconds) relates to the natural, pressure, and field broadening of spectral lines.
The larger the energy separation of the states between which the electron jumps, the shorter the wavelength of the photon emitted.

It becomes easy to connect or disconnect a new element without affecting the working of other elements.3. If any fault happened to the circuit, then also the current is able to pass through the circuit through different paths.Disadvantages: 1. It requires the use of lot of wires.2. We cannot increase or multiply the voltage in a parallel circuit.3. Parallel connection fails at the time when it is required to pass exactly same amount of current through the units.series connection:Advantages: 1. Series circuits do not overheat easily. This makes them very useful in the case of something that might be around a potentially flammable source, like dry plants or cloth.2. Series circuits are easy to learn and to make. Their simple design is easy to understand, and this means that it’s simple to conduct repairs .3. we can add more power devices, they have a higher output in terms of voltage .4. The current that flows in a series circuit has to flow through every component in the circuit. Therefore, all of the components in a series connection carry the same current.Disadvantages: 1.If one point breaks in the series circuit,the total circuit will break.2. As the number of components in a circuit increases ,greater will be the circuit resistance.
