Earth
Perigee
Example 15:
An artificial satellite is placed into an elliptical orbit about
the Earth. Telemetry data indicate that its point of closest
approach (called the perigee) is rp= 8.37.10° m Apogee --
from the center of the Earth, and its point of
greatest distance (called the apogee) is ra= 25.1. 10m A
from the center of the Earth.
The speed of the satellite at the perigee is vp = 8450 m/s.
Find its speed va at the apogee.
Reasoning:

According to the article, when our sleep/wake cycle breaks down, we are at an increased risk for all but which select one: a. respiratory illnesses b. dementia c. diabetes d. heart disease

Explain why methicillin resistant staphlococcus aureus (mrsa) is more prevalent now than it was only 30 years ago. a. antibiotics cause mutations in staphlococcus aureus that lead to an increase in the number of methicillin-resistant strains. b. methicillin resistance causes an infection to spread more rapidly.c. frequent and inappropriate use of methicillin-type antibiotics has provided selective pressure that has resulted in an increase in the proportion of methicillin-resistant strains of staphlococcus aureus.d. diseases like aids have made people more vulnerable to infections from staphlococcus aureus.
