Answer:
Below
Explanation:
To find the wave speed of a wave you can use this formula :
wavespeed (v) = (frequency) x (wavelength λ)
Plug in our values :
v = (10Hz) x (2m)
v = 20 m/s
Hope this helps!
Answer:
tensional force
Explanation:
It usually exist in fluid or any liquid substance where by an object is put before it
e.g An ant can walk on water without submersed in it.
Light acts like a wave and particle.
If there is an experiment designed to detect waves, you will see light as waves.
Similarly, if you set up an experiment to detect particles, you will see light as particles.
Basically, how you see light depends on the circumstances.
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.

Newton's first law of motion states that an object at rest stays at rest unless acted upon by a force while an object at motion stays in motion unless acted upon by an opposite force. Therefore, the ball in motion will stay at motion considering there is no friction force in the field, answer is A. If the field has friction force against the ball then it will slow down and stop eventually, answer is B.
