When Sun's light passes through any type if matter, some rays get absorbed while others get reflected. This is how colors are made and how we perceive them.
Answer:
C) 2700 N
Explanation:
As per FBD of the given situation we can say that torque due to tension in the spine is counter balanced by the torque due to weight of upper part of the body and the weight of the object
The tension force is acting at an angle of 12 degree
while both weight are acting perpendicular to the length
so here we have
now we have
T = 2700 N
Velocity =displacement
Change in time
D=72km/hr
Time=20s
But the S.I unit of velocity is m/s so you woul have to change 72km/hr to m/s
Changing 72km to m
1 kilometer=1000meters
Then, 72 kilometers =?
72•1000/1
=72000m
Changing 72hours to seconds
If 1 hour = 3600 seconds
Then 72 hours=?
72•3600/1
=259200 seconds
Velocity =displacement
Change in time
V= 72,000
259,2005
=0.028m/s
