Neglecting air resistance and the weight of the propellant, determine the work done in propelling a four-ton satellite to the following heights. a) 100 miles above Earth. b) 300 miles above Earth.

Step-by-step explanation:

Work = force × distance

force = mass × acceleartion due to gravity

a four ton satellite will have a force of 4× 1000 ×10 = 40KN (1000Kg = 1 ton)

1 mile = 1609.34 metre

therefore (a) 100 miles above the earth

work = 40000 × 100×1609.34

= 6437360000J

=6.4GJ

(b) 300 miles above the earth

work = 40000×300×1609.34

= 1.93×10¹⁰ J

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!

question: how many people can she serve?

answer: she can serve 16.66666667 people. so she can only give 16 people a complete serving.

question: does she have enough ice cream for her guests?

answer: no. explanation: she only has enough for 16 people to have a full serving. however, she can give a 17th person a partial serving.
