Answer:
given,
volume = 133.7 ft³
1 ft³ = 0.0283 m³
133.7 ft³ = 133.7 × 0.0283 = 3.784 m³
mass = 268 kg
1 kg = 2.204 lb
268 kg = 268 × 2.204 = 590.672 lb
weight of the fuel = 268 × 9.8 = 2626.4 N
1 N = 0.2248 lbf
2626.4 N = 2626.4 × 0.2248 = 590.414 lbf
![Density = \dfrac{mass}{volume}](https://tex.z-dn.net/?f=Density%20%3D%20%5Cdfrac%7Bmass%7D%7Bvolume%7D)
![\rho= \dfrac{268}{3.784}](https://tex.z-dn.net/?f=%5Crho%3D%20%5Cdfrac%7B268%7D%7B3.784%7D)
ρ = 70.82 kg/m³
specific volume = ![\dfrac{133.7}{590.672}](https://tex.z-dn.net/?f=%5Cdfrac%7B133.7%7D%7B590.672%7D)
= 0.226 ft³/lbm
The information is missing here but data that may support the existence of life in an exoplanet may include the discovery of atmospheric biological gases.
<h3>What is an exoplanet?</h3>
An exoplanet is any planet that surrounds another star beyond the sun, and therefore they are discovered by analyzing other galaxies in the Universe.
The existence of life in these exoplanets can be indirectly supported by the presence of gases that are only produced by organisms, which are detected by suitable telescopes that analyze emission spectra.
In conclusion, the information is missing here but data that may support the existence of life in an exoplanet include biological gases.

It is important for people to learn physics so that they can better understand the basic laws of the universe, and most importantly, so we can look at things with common sense, for you my friend i recommend watching <em>mythbusters</em>, they teach physics and make learning fun they teach you to look at the world with common sense. hope i helped!!! have a good day.
Answer:
w_f = m*V*cos(Q_n) / L*(m+M)
Explanation:
Given:
- mass of the putty ball m
- mass of the rod M
- Velocity of the ball V
- Length of the rod L
- Angle the ball makes before colliding with rod Q_n
Find:
What is the angular speed ωf of the system immediately after the collision,
Solution:
- We can either use conservation of angular momentum or conservation of Energy. We will use Conservation of angular momentum of a system:
L_before = L_after
- Initially the rod is at rest, and ball is moving with the velocity V at angle Q from normal to the rod. We know that the component normal to the rod causes angular momentum. Hence,
L_before = L_ball = m*L*V*cos(Q_n)
- After colliding the ball sicks to the rod and both move together with angular speed w_f
L_after = (m+M)*L*v_f
Where, v_f = L*w_f
L_after = (m+M)*L^2 * w_f
- Now equate the two expression as per conservation of angular momentum:
m*L*V*cos(Q_n) = (m+M)*L^2 * w_f
w_f = m*V*cos(Q_n) / L*(m+M)
Answer:
b. Static > sliding > rolling friction.
Explanation:
Static friction is greater than sliding friction. It takes more force to get an object to start sliding than to keep it sliding.
Sliding friction is greater than rolling friction. There are fewer points of contact for a round surface compared to a flat one.
