You would notice a greater elevation of blood pressure and pulse when an individual experiences hypertension. It is also known as high blood pressure. When blood vessels are blocked or are constricted due to several reasons, the pressure of the blood would be increased since there would be smaller area for the blood to flow. Consequently, the pulse or the heart rate would increase as well due to the increase in pressure. Factors that can cause hypertension would be lack of exercise, stress, when hormones are not regulated. It can also be caused by another illness like diabetes, kidney disorder,  obesity and many other.

Tasya [4]

Answer:

A(i)

The solution to this question is shown on the second uploaded image

A(ii)

The final speed is v = \sqrt{2L (\frac{F}{M} - gsin\theta )}

B

The block speed after a distance L  is  v= \sqrt{2L (\frac{F}{M} -gsin \theta )}

Explanation:

From the question  

The net force i the x-direction is mathematically represented as

               F_{net} = Ma

From the the diagram in the second uploaded image we see that

             F_{net} = F - Mgsin \theta

Therefore

              F- Mgsin\theta = Ma

Making a the subject

              a = \frac{F}{M} - gsin\theta

Applying the law of motion

                v^2 =u^2 + 2as

where  u = 0 m/s and s =L

       v^2 = 0 + 2(\frac{F}{M} - gsin \theta )L

=>   v = \sqrt{2L (\frac{F}{M} - gsin\theta )}

According to Energy conservation law and work theorem

           Workdone by F + Workdone by gravity = change in kinetic energy

Mathematically this is given as

                F * L - (mgsin \theta)L = \frac{1}{2} M (v^2-u^2)

   Since u = 0 m/s

                    L (\frac{F}{M} - gsin \theta ) = \frac{1}{2} v^2

                  v= \sqrt{2L (\frac{F}{M} -gsin \theta )}
