r 2
q 2
Here, r=2m F=10 −4 ×9.8N =10 −4 ×10N q 2 =F×4πε 0
×r 2
=10 −4 × 9×10 9
10×1
×(2) 2
= 9 10 −12
×(2) 2
So, q= 3 2

Write six dance conventions |
|
Answer» ong>Answer: 1. Dress to Flatter Yes, it is important to stand out, but convention attire has become so over the top trendy, that the art of CLASSIC, flattering apparel is almost a rarity.
What looks best on you? Are you prepared with attire that matches every style of DANCE offered?
For hip-hop, do you look like a hip-hop dancer? For ballet, do you look like a ballet dancer? Know your styles and dress appropriately (and professionally).
2. Physically PERFORM, Mentally Engage Dance convention classes require physical exertion for performance, but they also require an equal amount of mental engagement and focus.
3. Be Prepared Arrive early, be well-rested, hydrated, and have a plan in place for healthy meals and snacks throughout the workshop. Take care of your body!
4. Remove Yourself from Distraction Remove yourself from your in-class friends and parents (if they are observing). Find your own spot in the room where you can focus and absorb the information. Leave your cell phones and iPods outside.
When you are in the dance room, you have to be in the zone.
5. Focus When you are in class, be focused, engaged, and connected with the material being taught. If you disengage at any point, you will likely fall behind in the choreography/instruction.
If you fall behind, do not give up. Work hard to catch up, and keep trying! If you have a thoughtful, relevant question, do not be afraid to ask it.
6. Be Respectful & Kind Treat ALL dancers, instructors, and attendees with the utmost amount of respect.
Think about how your words, actions, and gestures may be interpreted. Do not leave or sit down in the middle of a class. Stay throughout the entirety of a workshop.
