Yes the lightest one will go the highest. if 2 objects with the same mass like a kilogram of feathers and a kilogram of steel they both would hit the ground at the same time bec they are both a kilogram
<h3><u>Answer</u> :</h3>
First of all see the attachment for better understanding
:D
<u>Eq. resistance between C and D</u> :
➝ 1/Rp = 1/6 + 1/6
➝ 1/Rp = 2/6
➝ <u>Rp = 3Ω</u>
<u>E</u><u>q. resistance of upper part </u>:
(All three are in series)
➝ Rs = 3 + 3 + 3
➝ <u>Rs = </u><u>9</u><u>Ω</u>
<u>Eq. resistance of lower part</u> :
(Both are in series)
➝ Rs' = 3 + 3
➝ <u>Rs' = 6Ω</u>
<u>Eq. resistance between A and B </u>:
(Rs and Rs' are in parallel)
➝ 1/Req = 1/Rs + 1/Rs'
➝ 1/Req = 1/9 + 1/6
➝ 1/Req = (2 + 3)/18
➝ Req = 18/5
<h3>➝
<u>Req = </u><u>3</u><u>.</u><u>6</u><u>Ω</u></h3>
Answer:
11.515 Joule
Explanation:
Volume of aluminium = V = 4.89×10⁻³ m³
Coefficient of volume expansion for aluminum = α = 69×10⁻⁶ /°C
Initial temperature = 19.1°C
Final temperature = 357°C
Pressure of air = 1.01×10⁵ Pa
Change in temperature = ΔT= 357-19.1 = 337.9 °C
Change in volume
ΔV = αVΔT
⇒ΔV = 69×10⁻⁶×4.89×10⁻³×337.9
⇒ΔV = 114010.839×10⁻⁹ m³
Work done
W = PΔV
⇒W = 1.01×10⁵×114010.839×10⁻⁹
⇒W = 11.515 J
∴ Work is done by the expanding aluminum is 11.515 Joule
It depends on what illness and what country you are in but Mayo Clinic and Johns Hopkins are good sources.
