Answer:
He has a speed of 16.60m/s after 35.0 meters.
Explanation:
The final velocity can be determined by means of the equations for a Uniformly Accelerated Rectilinear Motion:
(1)
The acceleration can be found by means of Newton's second law:
Where 
is the net force, m is the mass and a is the acceleration.
(2)
All the forces can be easily represented in a free body diagram, as it is shown below.
Forces in the x axis:
(3)
Forces in the y axis:
(4)
Solving for the forces in the x axis:
Where 
and 
:
Replacing in equation (2) it is gotten:
So the acceleration for the cyclist is 
, now that the acceleration is known, equation (1) can be used:
However, since he was originally at rest its initial velocity will be zero (
).
He has a speed of 16.60m/s after 35.0 meters
Your answer is C. Unbalanced
unbalanced forces change the direction and speed of objects, therefore it would change the constant speed of an object in motion.
Hope this helps u!
1.Light-collecting area
2.Angular resolution
To solve this problem we will apply the concepts related to the intensity included as the power transferred per unit area, where the area is the perpendicular plane in the direction of energy propagation.
Since the propagation occurs in an area of spherical figure we will have to
Replacing with the given power of the Bulb of 100W and the radius of 2.5m we have that
The relation between intensity I and 
Here,
= Permeability constant
c = Speed of light
Rearranging for the Maximum Energy and substituting we have then,
Finally the maximum magnetic field is given as the change in the Energy per light speed, that is,
Therefore the maximum value of the magnetic field is
