A book is held against a wall by applying a force perpendicular to the surface of the book. In a free body diagram of all of the forces acting on the book, what force would keep the book from sliding down the wall? A. force of hand B. force of gravity C. friction force D. normal force
In a free body diagram of all of the forces acting on the book, the force which would keep the book from sliding down the wall is; Choice A: Force of hand.
In modern mechanics, it is noteworthy to know that the normal force, F(n) is the component of a contact force which is perpendicular to the surface that an object contacts.In this instance, the surface which the object contacts is the wall.
It has however been stated within the question that;
A book is held against a wall by applying a force perpendicular to the surface of the book.In conclusion, the force which keeps the book from sliding down the wall is the force of the hand which is perpendicular to the object's surface of contact.

How are glucose and galactose epimers?
Kindly describe in brief how this epimer is different from manose and glucose one.
Help please and thanks!
Answer:
hehe I needed some brianliest plz OK
Explanation:
Glucose and galactose are monosaccharides that differ from one another only at position C-4. Thus, they are epimers that have an identical configuration in all the positions except in position C-4. ... Glucose and galactose are epimers that do not differ in position C-5 but differ in position C-4.
Glucose and mannose are epimers that differ at the C-2 carbon, while glucose and galactose are epimers that differ at the C-4 carbon, as shown below. When a molecule such as glucose converts to a cyclic form, it generates a new chiral center at C-1.

D. A cell that has a salt-bridge connection
Answer:
A. A cell with a negative cell voltage
Explanation:
other answer is wrong
An electrolytic cell is a cell with a spontaneous redox reaction (option B).
What is an electrolytic cell?Electrolytic cell is an electrochemical cell that utilizes an external source of electrical energy to force a chemical reaction that would otherwise not occur.
An electrolytic cell converts electrical energy into chemical energy. The redox reaction in the cell occurs spontaneously and is responsible for the production of electrical energy.
Therefore, according to this question, option B is correct.

To what extent does hypnosis work in regards to these behaviors?
A study by McNeilly and colleagues found that hypnosis may help quitters to focus on their own resources to curb cigarette cravings. Other researchers have suggested that success rates are caused by the relaxation effects of hypnosis. These might allow people to cope with nicotine addiction and nicotine withdrawal.
Would you recommend them? Why or why not?
I wouldn't recommend it because, The evidence for hypnosis as a successful smoking cessation method is a mixed bag. Some studies have seen high success rates, whilst others are more modest. A review of 59 different trials found that hypnosis is often better than no support at all.( so its a risk)

Use your knowledge of valence electrons and how they affect bonds to figure out how carbon (Group 14) and oxygen (Group 16)
would be attached to one another. In carbon dioxide (CO2), how is the compound structured? (Use "-" to represent a single
bond and "=" to represent a double bond) (1 point)
C-O-O
O=C-O
C=O-O
O=C=O
Answer: D
Explanation:
O=C=O
Carbon is in group 14 having four valence electrons and oxygen is in group 16 having six valence electrons hence the correct structure of CO2 is O=C=O.
Carbon and oxygen are nonmetals. Nonmetals form compounds by sharing electrons in a covalent bond.Carbon, a group 14 element has four valence electrons while oxygen, a group 16 element has six valence electrons.
Carbon can share four valence electrons with two oxygen atoms in CO2 to form the structure O=C=O. In this way, all the atoms now obey the octet rule.

3. How many moles of silver is 8.46x1024 atoms of
silver?
Answer:
14.05 molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\[/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
[tex]n = \frac{8.46 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 14.053156[/tex]
We have the final answer as
14.05 molesHope this helps you
