- Fnorm Fapp Fgrav = %3D m=15.0 kg a = 0.50 m/s/s, right ΣF = %3DThe water depth in a harbour is 17.8 m at high tide and 10.2 m at low tide. One cycle takes 12.4 hours tocomplete. Determine a function, ?(?), that models the depth ? (in meters) of the water at time ? (in hours)with ? = 0 corresponding to low tideYou are on a search and rescue team, trying to reach an injured hiker. You can see the light from a cell phone, and you use your compass to determine that the hiker is at an azimuth of 59 degrees (59 degrees east of north) from you. You use a rangefinder to estimate that the hiker is 800 meters away. You need to know the GPS coordinates of the hiker in order to tell the rescue helicopter where to find the hiker. (Keep at least one decimal place in your answer.) How many meters north of you is the hiker? m. How many meters east of you is the hiker?
- A scientist measures the distance to a mountain by shining a laser at a sensor held by her assistant, who is standing on the mountain. If the laser pulse is detected 3.2 x 10-5 seconds after it was emitted, calculate the distance between the scientist and the mountain in meters.The compound eyes of bees and other in- sects are highly sensitive to light in the ultra- violet portion of the spectrum, particularly light with frequencies between 7.5 × 10¹4 Hz and 1.0 x 10¹5 Hz. The speed of light is 3 × 108 m/s. What is the largest wavelength to which these frequencies correspond? Answer in units of m. What is the smallest wavelength? Answer in units of m.I have the answers for a-c. For a, the answer is 7.29 x 10-3 C. For b, the answer is 656 nm and c is 122 nm. Can you please help with d and e? Thank you.
