Answer: A
Wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.
The segment of the motion that net force act on the object causing a positive acceleration is segment 1.
<h3>
Motion of an object</h3>
The motion of an object occurs when a net force greater than zero acts on the object.
The force on the object is determined from Newton's second law of motion.
F(net) = ma
where;
- m is mass of the object
- a is acceleration of the object
<h3>Acceleration of the object from the graph</h3>
- Segment 1: the acceleration is positive
- Segment 2: the acceleration is zero
- Segment 3: the acceleration is negative
- Segment 4: the acceleration is zero
Thus, the segment of the motion that net force act on the object causing a positive acceleration is segment 1.

It is wavelength i think so!!!!
Answer:
The acceleration is 3.16x10¹⁷ m/s².
Explanation:
First, we need to find the magnitude of the Coulombs force (F):
<u>Where</u>:
K is the Coulomb constant = 9x10⁹ Nm²/C²
q₁ is the charge = 20x10⁻⁹ C
q₂ is the electron's charge = -1.6x10⁻¹⁹ C
d is the distance = 1.0 cm = 1.0x10⁻² m
Now, we can find the acceleration:
Therefore, the acceleration is 3.16x10¹⁷ m/s².
I hope it helps you!
