It took the train a total of 4 days to travel that long
Answer:
(A) The acceleration of Melissa is 0.211 m/s²
(B) The net force on Melissa is 9.5 N
Explanation:
Given;
radius of the carousel, r = 8.0 m
speed of Melissa, v = 1.3 m/s
mass of Melissa, m = 45 kg
(A) The acceleration of Melissa is given by centripetal acceleration;
(B) The net Force on Melissa is given by centripetal force;
We know,
V= f× wavelength
10.5= f×0.15
f=10.5/0.15
f= 70 Hz
A. A long thin wire because it is thin and long is give the most resistance. That is why people who walk on a wire across buildings have long thin wires.
Uneven heating is what causes the temperature differences
