Answer:
The of the lander would be 75.66 pounds
Explanation:
From the question we are given that the
Weight of the Philae on Earth is = 220 pound-mass
gravity of Mars is = 3.71 m/![s^{2}](https://tex.z-dn.net/?f=s%5E%7B2%7D)
Weight of the Philae on Mars is = ?
Now Mass is quantity of matter in an object so it is always constant for a particular object
Generally Weight = Mass × Gravity :
![\frac{Weight Of Earth}{Gravity Of Earth} = \frac{Weight Of Mars}{Gravity Of Mars}](https://tex.z-dn.net/?f=%5Cfrac%7BWeight%20Of%20Earth%7D%7BGravity%20Of%20Earth%7D%20%3D%20%5Cfrac%7BWeight%20Of%20Mars%7D%7BGravity%20Of%20Mars%7D)
Hence
Weight of the Philae on Mars is = ![\frac{Weight Of Earth *Gravity Of Mars}{Gravity Of Earth}](https://tex.z-dn.net/?f=%5Cfrac%7BWeight%20Of%20Earth%20%2AGravity%20Of%20Mars%7D%7BGravity%20Of%20Earth%7D)
![=\frac{200 *3.71}{9.81}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B200%20%2A3.71%7D%7B9.81%7D)
![= 75.66 pounds](https://tex.z-dn.net/?f=%3D%2075.66%20pounds)
Answer:
The annual operating cost of the refrigerator is $102.78.
Explanation:
Power consumed by the refrigerator = 247 W = 247/1000 = 0.247 kW
Daily operation of the refrigerator = 19 hours
Annual operation of the refrigerator = 365 × 19 = 6,935 hours
Annual energy consumed = 0.247 kW × 6,935 hours = 1712.945 kWh
1 kWh of electricity cost $0.06
1712.945 kWh will cost 1712.945 × $0.06 = $102.78
Annual operating cost = $102.78
