Answer:Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy.
Explanation:So, if the wavelength of a light wave is shorter, that means that the frequency will be higher because one cycle can pass in a shorter amount of time. ... That means that longer wavelengths have a lower frequency. Conclusion: a longer wavelength means a lower frequency, and a shorter wavelength means a higher frequency!
Extra explanation: All waves can be defined in terms of their frequency and intensity. c = λν expresses the relationship between wavelength and frequency.

What would happen if you touched an object that is the same temperature as your hand? Would any heat transfer happen? Explain your answer in 4-5 sentences.
Answer:
Explanation:
When two objects are in thermal equilibrium they are said to have the same temperature. During the process of reaching thermal equilibrium, heat, which is a form of energy, is transferred between the object
which means that it refers to transfer through a selectively permeable partition, the contact path.[1] For the relation of thermal equilibrium, the contact path is permeable only to heat; it does not permit the passage of matter or work; it is called a diathermal connection. According to Lieb and Yngvason, the essential meaning of the relation of thermal equilibrium includes that it is reflexive and symmetric. It is not included in the essential meaning whether it is or is not transitive. After discussing the semantics of the definition, they postulate a substantial physical axiom, that they call the "zeroth law of thermodynamics", that thermal equilibrium is a transitive relation. They comment that the equivalence classes of systems so established are called isotherms
plz dont be mad that i coppied it sounded so good so i wanted veryone to see it when they look bc i am dumb
How can you tell if science is supported? Or real?
Answer:
long answer so its below lol
Explanation:
You can tell if the science is "real" or supported based upon if there have been multiple experiments showing the same/smiliar answer, it has been proven by professionals, or if the science is published by professionals and such
Answer:
hold up ill see
Explanation:
dont know this tho
A 1000 kg boulder sits at the top of a 50-meter high cliff. Determine the amount of potential energy possessed by the boulder if the acceleration due to gravity is 9.8 m/s2. The boulder has_______(magnitude/ number)_______(units) of Potential Energy.
Answer:
490000J
Explanation:
Given parameters:
Mass of boulder = 1000kg
Height of cliff = 50m
Acceleration due to gravity = 9.8m/s²
Unknown:
Potential energy = ?
Solution:
Potential energy is due to the position of a body. It is expressed as;
P.E = mgH
m is the mass
g is the acceleration due gravity
H is the height
Now insert the parameters and solve;
P.E = 1000 x 9.8 x 50 = 490000J
Data:
m = 1000 kg
h = 50 m
g = 9.8 m/s^2
Find:
P.E = ?
Formula:
P.E = mgh
Solution:
P.E = mgh
P.E = (1000)*(9.8)*(50)
P.E = 490000 J
Result:
P.E = 490000 Joule

What does the Law of Conservation of Momentum stare about the momentum in a system in an inelastic collision?
Answer:
The law of momentum conservation can be stated as follows. For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.
Explanation:
Answer:
For any collision occurring in an isolated system, momentum is conserved. The total amount of momentum of the collection of objects in the system is the same before the collision as after the collision.
Explanation:
Which object would have the most momentum?
A.a 500-pound car moving at 20 miles per hour
B.a 200-pound car moving at 60 miles per hour
C.a 100-pound car moving at 80 miles per hour
D. a 50-pound car moving at 100 miles per hour
Answer:
B
Explanation:
Momentum is the product or multiplication of a body's mass and its speed.
Since all options have the mass and speed in the same units, there is no need for conversion.
A. 20 x 500 = 10000, B. 200 x 60 = 12000
The same goes for the rest!
