Answer
graph 2
Explanation
Velocity refers to the speed at which displacement changes.
Velocity = (change in displacement)/(change in time)
In graph 2, the slope of the curve is positive, indicating a positive velocity.
Acceleration indicates how velocity varies.
The incline of the same curve (graph 2) is diminishing. This suggests that the velocity is falling, signifying negative acceleration.
The equation that connects the various variables is:
distance between lines * sin(angle of diffraction) = order of band * wavelength
dsin(∅) = nλ
To calculate the spacing between the lines, we can use the information that there are 425 lines per mm, and since 1 mm is equivalent to 0.001 m, we find
d = 0.001 / 425 = 2.35 x 10⁻⁶ m
The wavelength is λ = 475 x 10⁻⁹ m
By substituting these values,
2.35 x 10⁻⁶ * sin(∅) = 1 * 475 x 10⁻⁹
∅ = 11.7°
Thus, the angle for the first-order bright band, or maxima, is 11.7°

Answer:
The correct response is:
1. KE Increases, PE Increases, ME Increases.
Explanation:
In this context, kinetic energy refers to the energy associated with an object's motion. Kinetic energy can be defined as the energy required to accelerate a mass from rest to a specified velocity, which it maintains once that speed is reached:
KE = 1/2 mv².
This definition indicates that KE is on the rise.
Potential energy is the energy stored in a body due to its position in a gravitational field:
PE = mgh,
which increases as the object is elevated against gravitational pull.
Since both kinetic and potential energies are increasing, it follows that the total mechanical energy (ME) is also rising:
ME = PE + KE.
