Speed of light relative to the boys = 300,000,000 m/s
Speed of light relative to a stationary observer on the side of the road =
<h3>300,000,000 m/s</h3><h3>What is special theory of relativity?</h3>
- The theory of special relativity explains how speed affects space, time, and mass.
- Small amounts of mass (m) can be interchangeable with large amounts of energy (E), as defined by the classic equation E = mc2, according to the theory, which offers a means for the speed of light to define the link between energy and matter.
<h3>What are the special relativity's guiding principles?</h3>
- The laws of physics should be independent of the uniform motion of an inertial frame of reference, and the speed of light should be constant in any such frame, according to two fundamental tenets that constitute the basis of the special theory of relativity.

<h2><u>Answer:</u></h2>
As you are looking for a new tennis partner. People should keep in mind that they should go for the one who most likely demonstrate good sportsmanship
Luis, when you pursue the principles in tennis, you realize when to talk up, you don't blast a racquet or shout, holler.
Whatever it is following the principles and being respectful it the most ideal approach.
Answer
given,
x = (3.9 cm)sin[(9.3 rad/s)πt]
general equation of displacement
x = A sin ω t
A is amplitude
now on comparing
c) Amplitude =3.9 cm
a) frequency =
f = 4.65 Hz
b) period of motion
T = 0.215 s
d) time when displacement is equal to x= 2.6 cm
x = (3.9 cm)sin[(9.3 rad/s)πt]
2.6 = (3.9 cm)sin[(9.3 rad/s)πt]
sin[(9.3 rad/s)πt] = 0.667
9.3 π t = 0.73
t = 0.025 s
