When did you notice a greater elevation of blood pressure and pulse?

1 answer:

6 0

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.

Mass

Explanation:

They physical property that is not the same among the four objects is their masses.

Mass is the amount of matter contained in a substance.

Specific heat is the amount of energy needed to raise the temperature of 1g of a substance by 1k.
Since the materials are made of the same metal, they have the same specific heat.
They will also have the same magnetism and electrical conductivity.
These properties are intensive property and do not depend on the amount of matter present.
Mass is an extensive property that depends on the amount of matter present.

A video game includes an asteroid that is programmed to move in a straight line across a 17-inch monitor according to the equati

Ainat [17]

Answer:

The asteroid's acceleration at this point is $2.71\ m/s^2$

Explanation:

The equation that governs the trajectory of asteroid is given by :

$x=6.5t-2.3t^3$

The velocity of asteroid is given by :

$v=\dfrac{dx}{dt}\\\\v=\dfrac{d(6.5t-2.3t^3)}{dt}\\\\v=6.5-6.9t^2$

At some point during the trip across the screen, the asteroid is at rest. It means, v = 0

So,

$6.5-6.9t^2=0\\\\t=0.971\ s$

Acceleration,

$a=\dfrac{dv}{dt}\\\\a=\dfrac{d(6.5-6.9t^2)}{dt}\\\\a=-13.8t$

Put t = 0.971 s

$a=-13.8\times 0.197\\\\a=-2.71\ m/s^2$

So, the asteroid's acceleration at this point is $2.71\ m/s^2$ and it is decelerating.

How original were Newton’s contributions to science? (In what ways did Newton depend on the mechanical view?)

kvasek [131]

Newton's new “reflecting telescope” was more powerful than ... Before Newton, scientists primarily adhered to ancient theories on ... laws of motion laid the groundwork for classical mechanics. Newton's research on motion helped give credibility to the heliocentric view. Newton also helped pioneer telescopic innovations, and he is sometimes credited with inventing the first reflecting telescope. He also conducted experiments using the prism, and developed a theory about the nature of color and light.
