Answer:
c. When they are traveling at low speeds, when they are almost stopped
Explanation:
The rate at which they ions loose energy depends upon its charge and mass and not on its speed. For example, We know that alpha particles have high mass and high charge so they loose more energy than gamma radiation which has no mass and no charge. The slower heavy particle which has high linear energy transfer.
Hence, when they travel at low speed they are almost stopped.
There the correct answer is option C
Answer:
4.57 degree
Explanation:
As the dolphin is under water, so the angle is angle of refraction which is equal to 48.4 degree.
refractive index of water, n = 1.333
Let the angle of incidence which is the angle between the incident ray and the normal is i.
By use of Snell's law
![n = \frac{Sin i}{Sin r}](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7BSin%20i%7D%7BSin%20r%7D)
![1.333 = \frac{Sin i}{Sin 48.4}](https://tex.z-dn.net/?f=1.333%20%3D%20%5Cfrac%7BSin%20i%7D%7BSin%2048.4%7D)
![Sin i = 1.333\times Sin 48.4 = 0.9968](https://tex.z-dn.net/?f=Sin%20i%20%3D%201.333%5Ctimes%20Sin%2048.4%20%3D%200.9968)
i = 85.43 degree
Angle made with the horizon = 90 - 85.43 = 4.57 degree
(the root of 4pi squared r squared ) / 86400
is velocity
r is 6.37*10^6
velocity is 1.36*10^5
