Answer:
F=BILsin90 when perpendicular sin90 =1 30T x50x30 so you can get 45000N
ANOTHER RUNNING DOG
Explanation:
In the given question it is to find a suitable reference point to describe the motion of dog. Here I could suggest that it is better to compare the dog with another running dog to create the relative speed difference to get a reliable motion variation.
Because the motion of dog is in the linear with respect to the another dog and to the acceleration produced by the dog in the required interval is easy to calculate with respect to another dog which is already in motion.
Hence, I suggest that Motion of dog can be analysed better by analyse the motion variation of dog with another dog running.
Answer:
Explanation:
Given:
- charge on the alpha particle,
- mass of the alpha particle,
- strength of a uniform magnetic field,
- radius of the final orbit,
<u>During the motion of a charge the magnetic force and the centripetal forces are balanced:</u>
where:
v = velocity of the alpha particle
Here we observe that the velocity of the aprticle is close to the velocity of light. So the kinetic energy will be relativistic.
<u>We firstly find the relativistic mass as:</u>
now kinetic energy:
Atomic number is equal to the number of protons and electrons
Atomic mass - protons = neutrons
protons + neutrons = atomic mass
I hope this helps
