I think that the best answer would be A. because biofeedback changes your brain waves which induce certain areas to create extra chemicals therefore stimulating you brain. where as medication is the chemicals so there fore there would be no constant to compare against.

Which of the following best compares longitudinal waves with transverse waves?
Semmy [17]
In longitudinal waves, the particles of the medium or a system displaces back and forth(parallel) in the direction of the propagation of waves. In transverse waves, the particles of the medium or a system displaces perpendicular to the direction of the propagation of waves. Therefore, C is correct.

An acrobatic airplane performs a loop at an airshow. The centripetal acceleration the plane experiences is 14.7 m/s2.  If it tak
Ivahew [28]

Answer:

754.8 m

Explanation:

The centripetal acceleration is given by

a=\frac{v^2}{r}

where v is the speed of the airplane and r is the radius of the loop.

We can rewrite the speed of the airplane as the ratio between the length of the circumference (2 \pi r) and the time taken:

v=\frac{2 \pi r}{t}

Substituting in the formula of the acceleration, we have

a=\frac{(2 \pi)^2 r^2}{t^2 r}=\frac{(2 \pi)^2 r}{t^2}

Re-arranging the formula and putting the numbers of the problem into it, we can find the radius of the loop, r:

r=\frac{at^2}{(2 \pi)^2}=\frac{(14.7 m/s^2)(45.0 s)^2}{(2 \pi)^2}=754.8 m
