Explanation:
As we know that car is moving in the curve of given radius
So the force on that car is given as
So for the first car we have
for other car we will have
now we will have
<u>Answer:</u>
The modern atomic theory has given by "John Dalton and framed postulates".
<u>Explanation:</u>
The fundamental role of atoms in chemistry is established by the modern theory of atoms mentioned in 1808 for the first time by an English scientist named John Dalton. This consists of three sections such as all matter is composed of atoms, atoms of the same element are the same while atoms of different elements are different, atoms combine to form compounds in full-number ratios.
The unique characteristic of the "number of protons" is that all atoms of the same compound share. While the atoms of the same element i.e having a similar number of protons can have different numbers of neutrons and such elements are called isotopes.
Answer:

Answer: 83.3 W
Explanation: I think, I’m not sure. If I’m wrong correct me ;)
C. longest wavelength
Explanation:
Photons with the lowest energy have the longest wavelength and the shortest frequency.
The energy of photons is given as:
E = hf =
where f is the frequency of photon
h is the planck's constant
∧ is wavelength
c is the speed of light
The more the frequency, the higher the energy of the photon.
Photons with low energy have long wavelength.
