Answer:Velocity = 6.325m/s
Directional angle= 18.43°
Explanation:
Using Right angle triangle
Let Velocity of ballon&hawk be VHB represent the height of the triangle.
Let Velocity of balloon angle ground be VBG represent adjacent of the triangle.
Let Velocity of hawk and ground BE VHG represent the hypothesis.
Theta = opp/Adj= VHB/VBG
using pythagorean
VHG= SQRT(VHB^2+VBG^2)
VHG= sqrt(2^2+6^2)
VHG= sqrt(4+36)
VHG= 6.325m/s
Tan theta= 2/6
Tan theta =0.3333
Tan^-1 0.3333=18.43°
If you mean in mass, then the mass of one proton is approximately equal to the mass on one neutron. If you mean how many of each, then the number of protons is equal to the number of electrons. If the number of electrons was different from the number of protons, then you'd have an ion. An ion with a positive charge is a cation, and an ion with a negative charge is an anion.

Answer:
a. Picture attached
b. V, X
c. 
d. It makes sense cosidering that a normal heart beat rate is between 60 and 100 beats per minute (bpm).
Explanation:
First we have to identify the unknown of this problem:

Considering the characteristics of the problem and that distance and velocity are specified, the acceleration is constant, for that reason we use the equations of uniformly accelerated motion as follows:

If we reorganize the equations, considering that
and
are zero because motion starts from rest , we have:

Finally, the analysis of the result leaves us to understand why the normal heart beat rate varies between 60 and 100 bpm.
Behaviorism is the aspect of psychology that believes that behavior is learned through rewards and consequences. There have been many scientific studies conducted on this idea.
