I'm 99% sure that it's "D. Electric Field"
I was agasint graviety I went to go run and I leaped into the air and flew straight down I broke three ribs and 3 fingers
Answer:
Tension in the string will be 19.293 N
Explanation:
We have given length of the string r = 42.1 cm = 0.421 m
Mass of the stone m = 1000 gram
We know that 1000 gram = 1 kg
Velocity in the circular path v = 2.85 m/sec
We have to find the tension in the string
Tension in the string will be equal to centripetal force
So tension , here m is mass, v is velocity and r is length of the string
So tension in the string
So tension in the string will be equal to 19.293 N
Could be that the speed of sound is 330m/s
