Answer:
(A) v = 14.8m/s
Explanation:
(A) V = sqrt(k/m) × A = sqrt(22/0.1) × 0.29 =14.8m/s.
Answer:
(D) Interference
Explanation:
Interference is a phenomenon characteristic for waves. When two waves meet, they interfere and result in a new wave. The precise shape of the resultant wave depends on the amplitude, frequency and phase of the constituent waves. In a most basic setting, two types of interference occur: constructive (resultant amplitude increases) and destructive (resultant amplitude decreases).
Solutes
Explanation:
These cleaning agents and additives are examples of solutes.
- Solutes are substances that dissolves in other substances called solvents to form a solution.
- The solutes are the cleaning agents and anti-knock additives.
- The solvents are the gasoline.
- When solutes dissolves in solvents they form solutions.
- A solution is a mixture that is homogeneous.
- For a solute dissolve in a solvent, they must both have the same property.
- Like substances will only dissolve in like ones.

Answer:
Now e is due to the ring at a
So
We say
1/4πEo(ea/ a²+a²)^3/2
= 1/4πEo ea/2√2a³
So here E is faced towards the ring
Next is E due to a point at the centre
So
E² = 1/4πEo ( e/a²)
Finally we get the total
Et= E²-E
= e/4πEo(2√2-1/2√2)
So the direction here is away from the ring
