Of the following, which is the best reason for why a woman's risk for cardiovascular disease increases after menopause?

Physics
1 answer:
MatroZZZ [7]2 years ago
6 0

Answer:

The best reason for the increased risk of cardiovascular diseases in women after menopause is the significant decrease in the levels of Estrogen in the body.

Detailed answer:

  • Due to the approach of menopause the estrogen levels in the blood decrease drastically.
  • Estrogen helps in relaxing the vessels and keeping them in their natural diameter.
  • But due to a drastic decrease in its level due to menopause, there is a high chance of cholesterol building up on the walls of the artery in the heart, which can cause many cardiovascular diseases.

Train cars are coupled together by being bumped into one another. Suppose two loaded train cars are moving toward one another, t
wolverine [178]

Answer:

final velocity =  0.08585m/s

Explanation:

We are taking train cars as our system. In this system no external force is acting. So we can apply the law of conservation of linear momentum.

The law of conservation of linear momentum states that the total linear momentum of a system remains constant if there is no external force acting on the system. That is total linear momentum before = total linear momentum after

total linear momentum before = linear momentum of first train car + linear momentum of second train car

We know that linear momentum = mv

where,

m = mass

v = velocity

thus,

total linear momentum before = m₁v₁ + m₂v₂

m₁ = mass of first train car = 135,000kg

v₁ = velocity of first train car = 0.305m/s

m₂ = mass of first second car =  100,000kg

v₂ = velocity of second train car =  −0.210m/s

Note: Momentum is a vector. So while adding momentum we should take account of its direction too. Here since second train car is moving in a direction opposite to that of the first one, we have taken its velocity as negative.

total linear momentum before = m₁v₁ + m₂v₂

                                                  = 135,000x0.305 + 100,000x(−0.210)

                                                  = 135,000x0.305 - 100,000x0.210

                                                  = 20,175 kgm/s

Now we have to find total linear momentum after bumping. After the bumping both the train cars will be moving together with a common velocity(say v).

Therefore, total linear momentum after = mv

m = m₁ + m₂ = 135,000 + 100,000 = 235,000

total linear momentum before = total linear momentum after

235,000v = 20,175

v =  \frac{20,175}{235,000}

  = 0.08585m/s

Evaluate the use of hydrogen as a fuel. Explain how hydrogen is produced. Write about the environmental impact of using diesel a
posledela

Explanation:

Hydrogen is used as a fuel because it has a high calorific value per molecule when burned in air and also burns explosively. When burned in air, it reacts with oxygen to produce water  which is safe for the environment. This same property of hydrogen of high explosiveness makes it difficult to store safely.  

Hydrogen can be produced through the electrolysis of water. However this is high energy consuming. The most common method is called steam-methane reforming. Methane from hydrocarbon is mixed with steam under high pressure and reacts to produce hydrogen and carbon monoxide.

Diesel and petrol and other petroleum products when burned produce carbon dioxide which is a greenhouse gas. Greenhouse gases when increasing in the atmosphere, cause greenhouse effect that results in global warming.

4) T F If two objects have the same moment of inertia, they must have the same mass.
lisov135 [29]

Answer:

False

Explanation:

The moment of inertia for a rigid body is given by

I=\int \rho(r) r^2 dV

where

\rho(V) is the density distribution of the object

r is the distance from the axis of rotation of the object

Essentially, the moment of inertia does not depend only on the mass of the object, but also on its shape. For example: for a solid cylinder, the moment of inertia derived from the formula above is

I=\frac{1}{2}MR^2

where M is the mass of the cylinder and R is its radius. As we see, I (moment of inertia) does not depend on the mass only: therefore, if two objects have same moment of inertia, this does not imply that they also have the same mass.
