Answer: Ain't its because how light the feather is ? It's not as heavy.
Explanation: With air resistance, acceleration throughout a fall gets less than gravity (g) because air resistance affects the movement of the falling object by slowing it down. ... Usually, resistance is not very high at low speed or for small or sharp objects (Google Source if needed to prove yours answer)
Somewhere in your book or your notes, you must have met the formula for the
gravitational attraction between two bodies. If you can go back and find it, you
only need to plug your numbers into that formula, and out will pop the answer.
Formula: <u>Force = G (mA x mB) / (distance)²</u>
If everything is in SI units, then G = 6.67 x10⁻¹¹ newton-meter² / kilogram²
You said that
mA = 8.1 kg
mB = 6.5 kg
distance = 0.5 m .
Force = (6.67 x 10⁻¹¹ nt-m²/kg²) (8.1kg x 6.5kg / (0.5m)² =
(6.67 x 10⁻¹¹ nt-m²/kg²) ( 52.65 kg² ) / (0.25 m²) =
<em>1.4047 x 10⁻⁸ newtons .</em>
That's roughly 5.052 x 10⁻⁸ ounce . (5% of one micro-ounce)
Answer:
Entropy is 14.17 J/k
Explanation:
The entropy change associated with the expansion of gas from v to 5.5v is given by
S=Rin(Vf/Vi)
We're Vi= iniatial volume and Vf is final volume
Hence S= 8.314in(5.5v/v)
S=14.17J/K
We know, f = ma
Here, m = 100 kg
a = 20 m/s²
Substitute their values,
f = 100 * 20
f = 2000 N
In short, Your Answer would be 2000 N
Hope this helps!
