Answer:
The remaining air between the cup and the rough surface exert pressure on the inner wall of the cup, due to this it does not stick on the rough surface.

<h3>
Answer:</h3>
AgCl + NaNO₃
<h3>
Explanation:</h3>
- The reaction between silver nitrate and sodium chloride is an example of a double displacement reaction.
- In a double displacement reaction compounds or salts reacts and exchange cations or anions to form new compounds or salts.
- In this case, silver nitrate and sodium chloride exchange anions and cations to form silver chloride and sodium nitrate.
- Therefore, the complete reaction is given by;
AgNO3 + NaCl → AgCl + NaNO₃
- But since silver chloride is a precipitate, the reaction may also be an example of a precipitation reaction.
As we know that circumference of the sphere is given as

here we know that

now we have

here we have


Answer: 24.7 degrees Max
Explanation:
m*g = 3 * 9.8 = 29.4 N. = Wt. of book.
Fp = 29.4*sin A = Force parallel to the
plank.
Fn = 29.4*Cos A = Force perpendicular to
the plank.
Fs = u*Fn = 0.46*29.4*Cos A
Fp-Fs = m*a
29.4*sin A - 0.46*29.4*Cos A = m*0 = 0
29.4*Sin A = 0.46*29.4*Cos A
Sin A = 0.46*Cos A
Divide both sides by Cos A:
Sin A/Cos A = 0.46
Replace Sin A/Cos A with Tan A:
Tan A = 0.46
A = 24.7 degrees Max.
