Answer:
speed = wavelength * frequency
Explanation:
Thenks and mark me brainliest :)
Answer:
601 nm
Explanation:
Energy of photon having wavelength of λ nm
= 
eV
Energy of 249 nm photon
=
=4.996 eV
Similarly energy of 425nm photon
=
=2.927 eV
Difference = 2.069 eV.
This energy will give rise to another photon whose wavelength will be
λ = 
= 601 nm.
Answer:
false
Explanation:
Resultant is a force with the combined effect of two or more forces. Even though a force is a vector, it is not part of the definition of a vector. Vectors a made of 2 or more components, depending on the dimension of the vector. A 2-D vector has two components, 3-D has three, and so on. In your case, you are probably generally working on 2-D vectors, so simply two components would be correct.

Answer: B. The south magnetic pole attracts the north pole of another magnet.
Explanation:
The correct statement below about the interaction between magnets, magnetic materials and charges is that the south magnetic pole attracts the north pole of another magnet.
We should note that a magnet typically consists of two poles which are the North Pole and the South pole. The opposite poles doesn't repel each other but attracts each other while same pole repels one another.
In this case, the North Pole will attract the South Pole while same magnetic piles repel e.g the North Pole will repel the North Pole.
