W1=200rpm*2pi/60=20.9rad/s
w2=200rpm-.10(200rpm)=180rpm
180rpm*2pi/60=18.8rad/s
a=(18.8-20.9)/10= -.21rad/s^2
I=1/2(28)(.15)^2
I=.315kg*m^2
Torque= -.21(.315)=.06615 N*m
Friction force= -.06615/.15=-.441 N
Normal force of man=.441/.2= 2.205 N
Final answer: -2.205 N
Explanation:
radio waves, which include visible light waves.
Answer:
138.4625 N/C
Explanation:
We have that the charge +4 nC is at the origin (0,0,0)
We have to find the electric field at point (-0.5,-0.1,0)
We know that distance between two points is given by
The electric field due to a point charge is given by
Answer:
1. A. is louder or softer
2. B. Has a different speed
Explanation:
Sorry if any or both are wrong
