The same braking force does work on these objects to slow them down. The work done is equal to their change in kinetic energy:
FΔx = 0.5mv²
F = force, Δx = distance traveled, m = mass, v = speed
Isolate Δx:
Δx = 0.5mv²/F
Calculate Δx for each object.
Object 1: m = 4.0kg, v = 2.0m/s
Δx = 0.5(4.0)(2.0)²/F = 8/F
Object 2: m = 1.0kg, v = 4.0m/s
Δx = 0.5(1.0)(4.0)²/F = 8/F
The two objects travel the same distance before stopping.
Answer:
Three terms in planetary science sound similar but have different meanings.Fill in the blanks below with the correct term. Important: Spelling matters! Use only lowercase! a. A solar eclipse occurs when the Moon passes across the disk of the Sun. b. An ellipse describes the shape of a planetary orbit about the Sun.c. The ecliptic describes the path of the Sun as seen against the background stars.
Explanation:
When the moon places between the Earth and the Sun, a solar eclipse occurs. The moon is capable to hide the solar disk, even with the sun being 400 times bigger than the moon but the moon is 400 times closer to the Earth than the sun.
Kepler's first law establishes that all the planets revolve around the Sun in an ellipse orbit, with the sun in one of the focus.
The ecliptic is the apparent path that the sun has in the celestial sphere as a consequence of the daily movement of the Earth around its axis
Unlike bacteria, archaea cell walls
do not contain peptidoglycan.
Archaea have different membrane
lipid bonding compared to Bacteria
and Eucarya.
Archaea have different metabolic pathways.
<u><em>Metabolic differences:
</em></u>
Archaea are very metabolically diverse, so
they are hard to generalize.
Archaea do not use glycolysis pathway to
break down glucose (though they do use
similar pathways).
Many archaea do not have functional Kreb’s
cycle pathways (but some do).
Transpiration is the evaporation of water through leaf stomata. It is the major force moving water through plants. Cohesion and adhesion create tension within xylem that helps move water upward.
