An object is placed 10cm to the right of a double concave diverging lens with a focal distance of 15cm. I. Using ray tracing:
- Find the image distance.
- Give three characteristics of the image (inverted/upright, smaller/larger, virtual/real).
II. Using lens equation:
- Find the image distance.
- Give three characteristics of the image (inverted/upright, smaller/larger, virtual/real).​

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

i had this question and the answer was 3.15 miles.

martina travels from school to her mom's office. from there, she walks to school. after school, she walks to the library and then to a friends house before finally ending back at home. find martina's total distance traveled.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
