Answer:
A combination of longitudinal & transverse
Explanation:
Answer:
Explanation:
a) Linear density is greater on the left side because the velocity of wave in a string is inversely proportional to the linear mass density of the string
b) We should start pulse from the left hand side so the reflected wave does not get inverted because the wave traveling from the denser to lighter medium gets reflected in the same phase.

Answer:
B)ωf = 1.8 rad/s
Explanation:
Given that
I= 2 kg.m²
d= 30 cm ,r= 15 cm
F= 4 N
t= 6 s
The torque produce by force F about point center of disc
T= F .r
T= 4 x 0.15 = 0.6 N.m
Lets take angular acceleration of the disc is α rad/s²
T= I α
0.6 = α x 2
α= 0.3 rad/s²
We know that
ωf = ωi + α t
ω =Angular speed of the disc
Initial angular speed ωi = 0 rad/s
ωf = 0 + 0.3 x 6
ωf = 1.8 rad/s
Therefore the answer is B.
