Answer
a) Draw an upward force from the bottom to indicate upthrust
b) Upthrust is an upward force acting on an object floating on a liquid... hence there is an upward force acting on the iceberg which causes it to float.
c) Unfortunately I don't know the answer.
Answer:
Prokaryotes are organisms that consist of a single prokaryotic cell. Eukaryotic cells are found in plants, animals, fungi, and protists. They range from 10–100 μm in diameter, and their DNA is contained within a membrane-bound nucleus. Eukaryotes are organisms containing eukaryotic cells.
The product is sodium chloride. In its clean, pulverized form, that's common table salt.
Answer:
11
Explanation:
According to Boyle's law:
Thus,
Where, n is the number of the balloons
From the question, it is given that:
For balloon:
P = Pa
V = 0.040 m³
For cylinder:
P = Pa
V = 0.0031 m³
So,
n = 11.625
<u>So, Maximum number of balloons = 11</u>
<span> resistivity Ag 15.9e-9 Ω-m
resistivity Fe 100e-9 Ω-m
temperature coefficient of resistivity
α = 0.0038/ºC Ag
R = R₀(1 + α∆T)
4*100 = 15.9(1 + (0.0038)∆T)
400/15.9 = 25 = 1 + (0.0038)∆T
(0.0038)∆T = 24
∆T = 6357ºC
add 25º to get 6382ºC </span>
