Answer:
The dimensional formula of the amplitude of a wave is given by,
[ M⁰L¹T⁰ ]
Where,
M = Mass
L = Length
T = Time
Derivation
The amplitude of wave = Maximum displacement
Since, the dimensional formula of displacement = [ M⁰L¹T⁰ ]
Therefore, the amplitude of a wave is dimensionally represented as [ M⁰L¹T⁰ ]
The acceleration of the wagon along the ground is 3.6 m/s².
To solve the problem above, we need to use the formula of acceleration as related to force and mass.
Acceleration: This can be defined as the rate of change of velocity.
⇒ Formula:
- Fcos∅ = ma................. Equation 1
⇒ Where:
- F = Force
- ∅ = angle above the horizontal
- m = mass of the wagon
- a = acceleration of the wagon
⇒ make a the subject of equation 1
- a = Fcos∅/m..................... Equation 2
From the question,
⇒ Given:
⇒ Substitute these values into equation 2
- a = 44(cos35°)/10
- a = 44(0.8191)/10
- a = 3.6 m/s²
Hence, The acceleration of the wagon along the ground is 3.6 m/s²

Answer:
Explanation:
according to ohms law we know that
v=IR
given current =2 amps
given resistance =6Ω
so voltage is
v=2*6 =12 V
The best logical answer is A
