How much work is required to lift a 600-kg satellite to an altitude of 1⋅1061⋅106 m above the surface of the earth? The gravitat
ional force is ????=????????m/????2F=GMm/r2, where ????M is the mass of the earth, mm is the mass of the satellite, and ????r is the distance between them. The radius of the earth is 6.4⋅1066.4⋅106 m, its mass is 6⋅10246⋅1024 kg, and in these units the gravitational constant, ????G, is 6.67⋅10−11

Answer:
121
Step-by-step explanation:
Given data as per the question
Standard deviation = = 840
Margin of error = E = 150
Confidence level = c = 95%
For 95% confidence, z = 1.96
based on the above information, the minimum number of clients surveyed by the travel agent is
= 120.47
= 121
hence, the 121 number of clients to be surveyed
Therefore we applied the above formula to determine the minimum number of clients
