Answer:
C?
Explanation:
My best guess would be C as it's the only answer that gives a reason behind the statement.
Answer:
91.017N
Explanation:
Parameters
L=4.67m, m=0.192kg, t = 0.794s, The pulse makes four trips down and back along the cord, we have 4 +4 =8 trips( to and fro)
so N= no of trips = 8, From Wave speed(V) = N *L/t , we have :
V= 8*4.67/0.794 = 47.0529 m/s.
We compute the cords mass per length, Let it be P
P = M/L = 0.192/4.67 = 0.04111 kg/m
From T = P * V^2 where T = Tension, we have
T = 0.04111 * (47.0529)^2
T = 91.017N.
The tension in the cord is 91.017N
Answer:
They speed up as temperature increases.
Explanation:
As temperatures increases within a molecule the particles will speed up.
The correct answer among all the other choices is "None of the above." <span>Electrons carry energy from a battery to a light bulb. The electron's potential energy will be converted into light energy. </span>Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.
