In the treatment of shock, which vasoactive drug results in reduced preload and afterload, reducing the oxygen demand of the hea
USPshnik [31]

Answer:

Nitropruside

Explanation:

Shock is a serious medical condition where oxygen levels in the body are low,  causing a low blood pressure which can lead to organ damage and sometimes death. Shock can be caused by low blood volume or inadequate pumping action of the heart.

Nitropruside is a very potent vasodilator. It acts on the arterial and venous smooth muscles, causing smooth muscle relaxation and leading to decreased cardiac preload and afterload. A reduction in afterload gives rise to an increased cardiac output and blood supply to the cells is increased. This in turn reduces the need for the heart to pump more blood (a compensatory response by the heart due to the low oxygen levels), thereby reducing the oxygen demand of the heart.

STatiana [176]

Answer:

The properties <u>that </u><u>do not vary</u><u> with the variation in the quantity of the material are called as </u><u>intensive property</u>.

While the <u>extensive properties</u><u> are those which </u><u>vary with the variation in the quantity of the material</u>.

Intensive properties:

Mass and volume

Extensive properties:

Density and melting point

Explanation:

The properties <u>that </u><u>do not vary</u><u> with the variation in the quantity of the material are called as </u><u>intensive property</u>.

While the <u>extensive properties</u><u> are those which </u><u>vary with the variation in the quantity of the material</u>.

Intensive properties:

Mass and volume, as with increase in quantity of the material mass and volume increases.

Extensive properties:

Density and melting point, as they remain constant for a object or material

Which of Newton’s Laws is demonstrated by a larger truck requiring more force to accelerate than a smaller car?
julia-pushkina [17]

Answer:

In your science class, you will learn about Newton’s laws of motion. Do you know why these laws are so important? When you throw a baseball or you bounce a basketball on the court, you can use Newton’s laws to explain the motion of the baseball or basketball. In fact, almost all motion in the world can be explained by these laws. Newton’s laws are useful when people design airplanes, trains, cars, sports equipment, toys, and many things that have to do with motion. Some people have trouble understanding Newton’s laws of motion because it’s hard to see how the laws work without any examples. One great way to understand these laws is to look at how they relate to cars in everyday life.

The First Law of Motion

“Every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impressed upon it.”

Can you see why it’s hard for some people to understand the first law? Those are some complicated words. To help you to understand better, let’s break it down and use the example of a car. The first part deals with an object in a “state of rest”. This means that the object is not moving. When your mom or dad parks the car in the garage or the shopping mall, the car is said to be in a “state of rest” because it is not moving. The car will not move until the engine is started and somebody drives it away. The second part deals with an object in “uniform motion”. This means that the object is moving at the same speed. When you mom or dad is using “cruise control” on a highway at 60 miles per hour, the car will be moving at that speed in a “straight line” until something happens to change it. What is this change? It depends. By using the brakes, your mom or dad can slow the car down or bring it to a stop. On the other hand, the car’s direction will be changed if it is hit by another motor vehicle.Explanation:
