Two in middle, so Newton's 2nd law. Equal and opposite force (both are moving). You have to assume no friction since it's an ice rink.
<span>Skater 1: 45kg 0.66m/s </span>
<span>Skater 2: xkg 0.81ms/ </span>
<span>Since force is equal, 45*0.66=x*0.81 </span>
<span>Solve for x. </span>
<span>So the answer would be 36.7kg</span>
Answer:
If they are metallic spheres they are connected to earth and a charged body approaches
non- metallic (insulating) spheres in this case are charged by rubbing
Explanation:
For fillers, there are two fundamental methods, depending on the type of material.
If they are metallic spheres, they are connected to earth and a charged body approaches, this induces a charge of opposite sign and of equal magnitude, then it removes the contact to earth and the sphere is charged.
If the non- metallic (insulating) spheres in this case are charged by rubbing with some material or touching with another charged material, in this case the sphere takes half the charge and when separated each sphere has half the charge and with equal sign.
One possible consequence is that the warmer temperature cause the polar ice to melt even faster
Fix critical violations during the inspection when and if possible (e.g., temperature issues, cross-contamination issues, sanitizing solution, etc.).
Review the inspection report and correct all noted deficiencies. Inform your employees of the violations and explain their importance. Determine why each violation occurred so you can try to avoid it in the future.
If you don't understand the violation, ask the health official to explain. Remember to not be confrontational; your health inspector should be your ally.
If you disagree with the inspector's findings, you can appeal the decision later. Typically, this involves calling the health department and talking with the inspector’s supervisor.
