Answer:
Electric field is a function 1/r^2
Explanation:
Moment about D=0
or,T1*6a-5w*3a-9w*2a=0
T2+T1=5w+9w
The pitch of the sound is perceived to be lower when an object is approaching you while making a sound.
<h3>What is sound?</h3>
Sound is a type of vibration capable of propagating in a suitable media (e.g., air or water).
The sound waves are called acoustic waves and they have a well-defined frequency and amplitude.

Answer:
<em>Yes, they are moving in opposite direction one to the other.</em>
Explanation:
Velocity is a vector quantity, which means that it has both magnitude and direction. The magnitude shows the size of the velocity, and the direction shows which way it is moving in reference to a chosen reference direction. If the red box is assigned a positive velocity, and the blue box is assigned a negative velocity, as indicated in the question, then it means that the red box, and the blue box, both move in opposite direction to the other.
Answer:
The path of an object in uniform motion is a straight line.
