Do you have any thoughts on how to approach the problems, so you could give your ideas and people could comment rather than just giving the answers? Are you familiar with the equations for length contraction and time dilation?
Yes, that's the right approach for question (i).versaknight said:yes what i did was calculate the reltive velcocity of the orion rocket with respect to the crew of sirius and i used this velcity to find the contracted length iss that correct
versaknight said:well i don't think so beacuse for orion , sirius will be moving at the same relative speed away from him. since they have the same length, the contracted length will be the same and the time taken will be the same.. that's what i think
The best way to prepare for an exam is to start studying early and consistently. Review your notes and materials regularly, create study guides or flashcards, and practice answering sample questions.
To stay calm and focused during an exam, make sure to get a good night's sleep, eat a healthy breakfast, and take deep breaths when feeling overwhelmed. Also, read through all the instructions carefully and manage your time wisely.
If you are struggling with a particular subject, seek help from your teacher or a tutor. They can provide additional resources or clarify any confusing concepts. Also, try to break down the material into smaller, manageable chunks and practice regularly.
This depends on personal preference and the subject being studied. Some people find studying alone more effective as it allows them to focus better, while others find studying with a group helpful for discussing and reinforcing information. Experiment with both methods and see what works best for you.
To manage stress and anxiety before an exam, make sure to take care of your physical and mental well-being. Get enough rest, exercise, and eat healthy foods. Also, try relaxation techniques such as deep breathing or meditation. Remember to stay positive and believe in yourself.
