Answer:
υ = 5.62 x 10¹⁴ Hz
Explanation:
The process of of formation of photons takes place due to interaction of a particle with its anti-particle is called Annihilation of Matter. Here SPARTYON absorbs anti-SPARYTON to form 2 photons. Applying conservation of energy to the to this scenario, we get:
2(Energy of Each Photon) = Rest Mass Energy of SPARTYON + Rest Mass Energy of anti-SPARTYON
where,
υ = frequency of each photon = ?
m₀ = rest mass of SPARTYON = mass of anti-SPARTYON = 455*Mass of electron
m₀ = 455(9.1 x 10⁻³¹ kg) = 4.14 x 10⁻²⁸ kg
c = speed of light = 3 x 10⁸ m/s
h = Plank's Constant = 6.625 x 10⁻³⁴ J.s
Therefore, using these values in the equation, we get:
<u>υ = 5.62 x 10¹⁴ Hz</u>
Answer:
v = 7.9 m/s
Explanation:
length of the vine (L) = 20 m
initial angle with the vertical = 45 degrees
final angle with the vertical = 30 degrees
acceleration due to gravity (g) = 9.8 m/s^{2}
speed (v) =?
to solve this problem we can apply the equation below:
loss in potential energy = gain in kinetic energy
m x g x h = 1/2 x m x
v =
before we can apply the above we need to get our height
height = initial vertical height - final vertical height
height = (L - L cosθ2) - (L - L cosθ1)
height = (20 - 20cos45) - (20 - 20cos30) = 3.2 m
v =
v = 7.9 m/s
