A car driving at a constant speed around a circular track
Umm, I guess it really depends on what these numbers are for but what I can say is if you put this under physics then decimals are used very often and help express parts of numbers for this particular problem.And if it's directly between the two then it's 0.50 added to that smaller number,I hope that helps
If the length and linear density are constant, the frequency is directly proportional to the square root of the tension.
The distance for both Parts A and B are given in the question.
A balloon drifts 140m toward the west in 45s.
The wind suddenly changes and the balloon flies 90m toward the east in the next 25s.
To find the total distance, we can just add.
140 + 90 = 230m
Best of Luck!
Answer:
Explanation:
heat lost by coffee = heat gain by aluminum spoon
heat lost by coffee = mc ( 85° C - T)
175 ml of water = 175 grams
175 grams = (175 / 1000) kg = 0.175 kg
heat loss by coffee = 0.175 × 4182 J/Kgk ( 85 - T) = 731.85 ( 85-T) = 62207.25 - 731.85 T
heat gain by aluminum spoon = 0.012kg × 897 J/kgK ( T - 22) = 10.764 T - 236.808
10.764 T - 236.808 = 62207.25 - 731.85 T
10.764 T + 731.85 T = 62207.25 + 236.808
T = 84.086 ° C approx 84°C
