Lean your shoulders back and your waist forwards. Use your arms as a counter weight.
Answer:
The angle it subtend on the retina is
Explanation:
From the question we are told that
The length of the warbler is
The distance from the binoculars is
The magnification of the binoculars is
Without the 8 X binoculars the angle made with the angular size of the object is mathematically represented as
Now magnification can be represented mathematically as
Where is the angle the image of the warbler subtend on your retina when the binoculars i.e the binoculars zoom.
So
=>
Generally the conversion to degrees can be mathematically evaluated as
It took so long because at the time there was no way for people to study the behavior formally. im not sure what helped it get recognized but i know wihelm wundt helped get it recongnized.
sorry i couldnt be much help
Answer:
a)
b)
c)
Explanation:
the gravitational potential energy is given by:
The kinetic energy is given by:
the initial kinetic energy is zero because the motion started from rest, so:
applying the conservation of energy theorem:
The work done by the friction force is given by:
the angle of the force is 180 degrees because it's against the movement:
Answer:
motion energy
Explanation:
motion wnergy is the sum of potential and kinetic energy
