Answer:
P = 741.7 Pa
Explanation:
Pressure:
It is the force applied on object per unit area. The force is applied perpendicular to the surface.
Mathematical expression:
P = F/A
P = pressure
F = force
A = area
Given data:
Weight = 178 N
Area = 10 cm × 24 cm
Pressure = ?
Solution:
Area = 10 cm × 24 cm
Area = 240 cm²
Area = 240 /10000 = 0.024 m²
Formula:
P = F/A
P = 178 N / 0.024 m²
P = 741.7 Nm⁻²
Nm⁻² = Pa
P = 741.7 Pa
Answer:
The answer to your question is below
Explanation:
A.
[H₃O⁺] = 2 x 10⁻¹⁴ M
pH = ?
Formula
pH = - log [H₃O⁺]
Substitution
pH = - log [2 x 10⁻¹⁴]
Result
pH = 13.7
B.
[H₃O⁺] = ?
pH = 3.12
Formula
pH = - log [H₃O⁺]
Substitution
3.12 = - log [H₃O⁺]
![10^{-3.12} = [H_{3} O^{+}]](https://tex.z-dn.net/?f=10%5E%7B-3.12%7D%20%3D%20%5BH_%7B3%7D%20O%5E%7B%2B%7D%5D)
Result
[H₃O⁺] = 7.59 M
Answer:
Glycogen. Cellulose. Amylose. Cellulose. Amylopetin and Glycogen. Amylopetin and Cellulose.
Explanation:
Glycogen is the form that glucose is stored in human body.
Cellulose is the structural part of plant cell walls and human cannot digest it.
Amylose is the polysaccharide linked mainly by the the bonds of
1,4 glycosidic.
Cellulose is an unbranched polysaccharide linked mainly by the bonds of
1,4 glycosidic.
Amylopetin and Glycogen are branched polysaccharides linked by the bonds of
1,4 glycosidic and
1,6 glycosidic.
Amylopetin and Cellulose are mainly stored in plants.
Answer:
823.7g
Explanation:
Using the formula as follows:
Q = m × c × ∆T
Where;
Q = amount of heat (J)
m = mass of substance (g)
c = specific heat capacity (J/g°C)
∆T = change in temperature (°C)
Using the information given in this question as follows:
Q = 6,400 J
m = ?
c of soil = 0.840 J/g°C
∆T = 9.25°C
Using Q = mc∆T
m = Q ÷ c∆T
m = 6,400 ÷ (0.840 × 9.25)
m = 6400 ÷ 7.77
m = 823.7g
