1 ) a) increasing its thickness
2) c)potential difference
1) 3 miles/Hour
The speed is defined as the distance covered divided by the time taken:
where
d = 1.5 mi is the distance
t = 0.5 h is the time taken
Substituting,
2) 1.34 m/s south
Velocity, instead, is a vector, so it has both a magnitude and a direction. We have:
is the displacement in meters
is the time taken in seconds
Substituting,
And the direction of the velocity is the same as the displacement, so it is south.
B. Australia and Antarctica were a single landmass in the past.
Explanation:
The most likely explanation for why the fossils of this plant are found on these two continents is that Australia and Antarctica were a single landmass in the past.
This evidence is vastly supported by the theory of plate tectonics originally, the theory of continental drift.
- Plate tectonics proposes that all land masses were once joined together as a single supercontinent called Pangaea.
- The region of Antartica and Australia were once joined as a single continental mass.
- The plant must have developed together at that time.
- When the continents moved apart, they still had the fossils.

Answer:
Explanation:
Given that,
Potential difference of battery is
V = 24V
Total charge battery can transferred
q = 340,000C
Work done by the battery?
Work done is given as
W = qV
Where q is charge in Columbs
V is potential difference in Volts
Then, W = qV
W = 340,000×24
W = 8,160,000 J
Work done by the battery over it's useful life time is 8,160,000J
Sorry i can’t help sorry good luck tho!!!!
