A charged particle leaves a potential difference with a speed of 1221 m s and is headed East. The particle then enters a uniform magnetic field directed into the page with magnitude 42.42 T. When the particle enters the uniform field, it undergoes a specific type of motion, of which begins turning the particle toward the south.(a) Draw and fully label a diagram of the situation described above, including the motion of the particle inside the B-field.(b) Once the particle enters the uniform magnetic field, what type of motion will the particle undergo?(c) If this motion has a radius of 9.31 cm and the magnitude of the charge on the particle is 5.80 µC, determine the mass of the particle.(d) Is the charge on the particle positive or negative? How do you know? (e) (EC) The particle is a moving charged particle and so it establishes a current loop; as a current, it would produce a magnetic field of its own. Determine the magnitude and direction of the magnetic field produced by the "current loop," at the center of the loop. What is the total magnetic field at the center of the loop, if we superpose (add) the external field and the field produced by the "current loop?"

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me

3. dark matter

empty space could also be a simple vacuum
