Answer:
Tension= 475N
Force= 225N
Explanation:
The question is not complete, here is the complete question
Also, see attached a free body diagram for your reference
<em>"A 20.0-kg uniform plank is supported by the floor at one end by a vertical rope at the other as shown in the figure. A 50.0-kg mass person stands on the plank a distance three-fourths of the length plank from the end on the floor. </em>
<em>a. What is the tension in the rope? </em>
<em>b. What is the magnitude of the force that the floor exerts on the plank?"</em>
<em />
given data
mass of man=50kg
mass of plank=20kg
length of plank=10m
<em />
let us make the lenght of the rope be d
The torque about the floor
That is taking moment about the floor
Force will be also zero

Answer:
Wavelength = 478.46 m
Explanation:
It is given that,
A local AM radio station broadcasts at a frequency of 627 kHz, f = 627000 Hz
We need to find the wavelength at which it is broadcasting. The wavelength is given by :
So, the wavelength is 478.46 m.
