Changing direction is the correct answer
Answer:E
Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly. Wavelength always increases with speed, as frequency is fixed at source and speed= freq x wavelength
The speed of sound in room temperature air is 346 meters per second.
<span>You can use one or more of your five senses to make observations during an inquiry activity.
we have nervous system which has special sensory system, we have sensory organs and senses, the five senses are touch, smell, hearing, sight and taste. every sense is related to an organ, like we can touch with hands, hear with ears, sight is related to eyes, we can smell with nose and taste with tongue.

- The net force acting on the box is 6N
<h3>Explain the concept?</h3>
- The net force on an object is the sum of all the individual forces acting on it.
- If two opposing forces act on an object, the net force is the difference between the two forces.
- When two forces act in the same direction on an object, the net force is the sum of the two forces.
Here the two force 3N and 3N acting on same direction, so
net force = 3N + 3N
= 6N
Forces that are balanced are those that are opposite in direction and equal in size, but here the equal forces acts in same direction so it is unbalanced
