Models represent objects, events, and processes in the real world.
Models are often used when an object, event, or process
occurs too slowly or too quickly;
is too small or too large;
is too complicated or too dangerous.
The ocean is spreading at such a slow rate that it would take scientists 50 or more years to collect enough meaningful data from the ocean floor to complete a study. Therefore, scientists use models in order to both predict how the floor will keep spreading and to understand what the ocean floor looked like thousands of years in the past.
Answer:
option (a)
Explanation:
The magnetic field is produced by the electric current, and the direction of magnetic field is given by the Maxwells' right hand rule.
The magnetic field is also be produced by the time varying magnetic fields.
You have to find interia using I=mr^2.
m=75+10
radius = 11
Then you have to substitute in first formula above to find the angular speed.
14020=(75+10)x v x 11
v= 14020/ (85x11) = 15m/s
To find linear speed, use V=wr.
Equation: V = 11*1.363 = 15m/s = 33.6mi/hr
Hope this helps! :)
