To solve this problem we will apply Newton's second law and the principle of balancing Forces on the rope. Newton's second law allows us to define the weight of the mass, through the function
Here,
m = mass
a = g = Gravitational acceleration
Replacing we have that the weight is
Since the rope is taut and does not break, the net force on the rope will be zero.
Therefore the tensile force in the rope is 98N

here's your answer
Fossil fuel use is integrated into the fabric of American society. Natural gas, petroleum and coal together accounted for more than 80 percent of energy use in the United States in 2012. Meanwhile, more than 5 gigawatts of solar power capacity was scheduled to come online in 2013 -- about as much capacity as was added for coal plants over a nearly 20-year span. The characteristics of solar power and fossil fuels drive the desire to adopt a particular energy source for a specific application, and they also limit the possible applications of a specific energy source.

Answer:
Explanation:
given,
Speed of a wave on violin A = 288 m/s
Speed on the G string = 128 m/s
Force at the end of string G = 110 N
Force at the end of string A = 350 N
the ratio of mass per unit length of the strings (A/G). = ?
speed for string A
.......(1)
speed for string G
........(2)
Assuming force is same in both the string
now,
dividing equation (2)/(1)
