Answer:
Option B
Explanation:
The phase difference is found by subtracting the 2.3m for the receiver from the other speaker which is 2.9m hence
Phase difference= 2.9-2.3= 0.6
Gravitational potential energy is caused when an object is resting above the ground. It is released when the object is falling, not by burning substances.
Answer:
The theory of Relativity state that :<u>Special relativity applies to all physical phenomena in the absence of gravity and General relativity explains the law of gravitation and its relation to other forces of nature. </u>
Answer:
rA = 9 i + 9 j
rB = 12 i - 9 j
rB - rA = 3 i - 18 j
so distance in between them
= √[3×3 + 18 × 18 )
= √(9+324)
= √333
= 18.3 m
