I'm pretty sure it's the neutron star.
As we know that electric flux is given by


so in order to increase the flux we have two options
1. By increasing the area of the disc
2. by changing the orientation of disc so the area of the disc is parallel to the electric field
so correct answer will be
<em> A. increasing the area of the disk</em>
I would say your answer to this question would be D
Wherever the change in the body happened will detect the stimuli and send the signals to the brain and Spinal does
Answer:
Explanation:
Let lift force F be created by propellers at angle of Ф with the horizontal .
The vertical component of this force will balance the weight of helicopter and horizontal component will balance the air resistance .
F sinФ = mg = 2750 x 9.8 = 26950 N
F cosФ = 7510 N
Squaring and adding ,
F² = 26950² + 7510²
= 726302500 + 56400100
= 782702600
F = 27976.82 N .
