What is an electromagnetic wave?
EM waves are another name for electromagnetic waves. Electromagnetic radiations are made up of electromagnetic waves created when an electric field collides with a magnetic field.
Electromagnetic waves may alternatively be defined as the combination of oscillating electric and magnetic fields. Maxwell's equations are solutions to electromagnetic waves.
Of all electromagnetic waves, radio waves have the longest wavelength.
Hence the three electromegnetic waves that have longer wavelengths that make up visible light will be microwaves, radio waves, and infrared light.

Superkid, finally fed up with Superbully's obnoxious behaviour, hurls a 1.35 kg stone at him at 0.501 of the speed of light. How much kinetic energy do Superkid's super arm muscles give the stone
Answer:
See below
Explanation:
A lot !
KE = 1/2 m v^2
= 1/2 * 1.35 * ( .501 * 3 * 10^8)^2 =
1.5248 x 10^16 j
kinetic energy do Superkid's super arm muscles give the stone is 62.6 × 10⁶ J.
What is kinetic energy ?Kinetic energy is the energy associated with a motion of a body. When a body is in motion having mass m then it has kinetic energy. Kinetic energy is denoted by K or T. it is expressed in joules. Kinetic energy is given by,
K = 1/2 mv²
Hence an object having zero mass or zero velocity have zero kinetic energy.
In this problem the stone is moving with velocity which is comparable with the speed of light, hence we have to find relativistic kinetic energy.
The relativistic kinetic energy is given by,
[tex]K = m_{0} c^2(\frac{1}{\sqrt{1-\frac{v^2}{c^2}} } -1)[/tex]
putting all the values in the equation
[tex]K = 1.35*3*10^8(\frac{1}{\sqrt{1-\frac{(0.5c)^2}{c^2} } }-1 )[/tex]
K = 62.6 × 10⁶ J

The wavelength and frequency of the sound in the string is greater than the wavelength and frequency of the sound in the air.
Wavelength and freqeuncy of the soundThe wavelength and frequency of the sound is determined using the following formulas.
v = fλ
f = v/λ
λ = v/f

A student has available two rods, one charged positively and one charged negatively. Using
one of these rods, she gives the sphere a uniform negative charge by induction
State which rod she chooses, and describe the procedure she follows.
The rod she chooses, to give the sphere a uniform negative charge by induction is the positively charged rod.
Charging by inductionCharging an object by induction is a process of inducing a charge on the object by bringing another charged object close to it.
Charge on the sphereWhen a positively charged rod is brought near a neutral sphere (equal negative and positive charge), the positive charge of the rod will repel the positive charge of the sphere, leaving the sphere with excess negative charge.
Thus, the rod she chooses, to give the sphere a uniform negative charge by induction is the positively charged rod.

An astronaut floating alone in outer space throws a baseball. If the ball moves away at 20 m/s, the astronaut will:.
Answer:

Explanation:
Since many wavelengths of light are measured in nanometers, it's useful to know that planck's constant (h) multiplied with the speed of
light (c) is equal to 1240 eVnm.
This is useful, as E = hf, or otherwise written as E= .
With this information in mind, solve the following:
A photon has 1.6 eV of energy. What is the wavelength of this photon?
O a
410 nm
Ob
775 nm
Ос
1984 nm
Od
306 nm
Answer:
E = h f and since f = c / λ we have E = h c / λ
Thus λ = h c / E
Also, 1 ev = 1.6E-19 C
λ = 6.63E-34 * 3.0E8 / (1.6 * 1.6E-19)
λ = 6.63 * 3.0 / (1.6 * 1.6) * E-7
λ = 7.77E-7 = 777 nanometers

One way people are using technology to protect the environment is:
Using digital devices for communicating and storing information means that there is less reliance on paper, which reduces deforestation. Since trees are an important source of oxygen and also absorb carbon dioxide, this further reduces climate change.
Environmental technology has enabled us to capture this naturally occurring energy and convert it into electricity or useful heat through devices such as solar panels, wind, and water turbines.

Consider the following statements.
A. Heat flows from an object with higher
thermal energy to one with lower thermal energy;
B. Heat flows from an object at higher tem-
perature to an object at lower temperature;
C. Heat flows from an object in liquid state
to an object in solid state.
Which statements are true?
Answer:The heat flows from an object at a higher temperature to the object at a lower temperature. Thus the option A is correct.
Explanation:What is heat flow?
The flow of heat is the transfer of heat that concerns its generation, use and conversion, and exchange.The heat flow follows the laws of the thermodynamics. Heat will flow from the body that is at a higher temperature and will move towards a body of a lower temperature. Thereby maintaining an equilibrium state. As energy is needed to warm or heat up the cold body there is an exchange of energy that takes place.

What happens to the energy of a wave if the amplitude of the wave is doubled?
How does the frequency of a wave relate to the energy of the wave?
Answer:
See below ↓
Explanation:
We know that the energy of a wave is directly proportional to the amplitude of a the wave. That means it directly varies, so when one increases/decreases, the other does the same.
Therefore, when the amplitude of a wave is doubled, the energy of the wave is also doubled.
Similarly, in the case of the frequency of the wave, it is also directly proportional to the energy of the wave.
