Answer:
Q
Explanation:
To know which symbol defines the wavelength, we must know the definition of wavelength.
Wavelength can be defined as the distance between two successive crests (i.e the highest part) or troughs (the lowest part) of a wave.
Considering the diagram given above, Q shows the distance between two successive crests (i.e the highest part) of the wave. Therefore, Q is the wavelength of the wave given in the diagram above.
Gravitational potential energy = mass x gravitational field strength (g) x height
Answer:
Explanation:
Given that,
Block of mass M= 6kg
Initially at rest u =0
A force F = 12N is used in pulling it along the horizontal
Distance moved s = 3m
Speed.
Using Newton second law
ΣFx = ma
12 = 6a
Then, a = 12/6
a = 2m/s²
Then, using equation of motion
v² = u² + 2as
v² = 0² + 2×2×3
v² = 0 + 12
v = √ 12
v = 3.46 m/s
I believe the answer is potential energy if i remember correctly.
Answer:
maximum acceleration will be
Explanation:
We have given that mass of the box m = 29 kg
Coefficient of static friction
Acceleration due to gravity
For maximum acceleration
So acceleration will be
So maximum acceleration will be
