Answer:
Explanation:
in all the question we have to use same technique
in 1 question
weight/force exerted by dorje(F)=1500N
total surface area of sole(A)=0.5m²
we know that,
P=
or, p=
∴ P=3000pa
in question 2nd
pressure(P)=40 pa
force exerted by block(F)=80N
we know,
pressure(P)=
area=
∴area =2m
ow you can do other by yourself
The answer is a. True
The body loses water in the first place through kidneys in the form of urine. A less is lost through evaporation from a skin, as a sweat, or through exhalation, by breathing out water vapor. In some cases, such as intensive exercise or hot weather, increased amount of water can be lost through sweat.
I am: A) DNA
DNA is double-stranded molecule which is often also it's most known feature. Perhaps less known (depends on who you ask) are facts that it also has thymine and not uracil (uracil is found in RNA). It has four nitrogen bases and it contains deoxyribose sugar (another hint that it's DNA and not RNA).
