A and c
do not complete the circuit there is no battery on a and paper dose not conduct electricity
Answer:
500m/s
Explanation:
From the question we are given the following;
mass per unit length = 4.80 x10^-3 kg/m
Tension T = 1200N
Speed of the wave is expressed as;
v = √T/m
v = √1200/0.0048
v = √250,000
v = 500m/s
Hence the speed at which the wave travels on this string is 500m/s
1. I don't see a graph
2. It could be because a liquid could be evaporating in the process
3. It could be that the liquid is getting colder
4. 1 liquid is medium and moving a the normal pace
D = 1/2gt^2 <-- free fall formula
d = (0.5)(9.81)(1.5^2)
d = 11.03625
d = 11.04 m
hope this helps and have a great day :)
