How is energy conserved in a process of a heart beat

Physics
1 answer:
Westkost [7]3 years ago
3 0

Explanation:

energy conservation and fatigue management -tiredness is a common symptom of a heart attack and although rest is important activity is also required to facilitate a return to health. an occupational therapist said energy conservation and fatigue management is techniques to be implemented throughout the day. to help clients achieve their goals

If you increase the voltage what will the current do
o-na [289]

Answer:

The power will remain the same for a particular load as we are not changing the load. so if we increase the voltage, the current will decrease to make the net power consumed by the load same as before. If we increase the current, the voltage will decrease for making the power same. The power will only change when we changes the load.

Describe what happens to the gravitational force between two objects when their masses are increased
Inessa [10]

Answer:

So as the mass of either object increases, the force of gravitational attraction between them also increases. If the mass of one of the objects is doubled, then the force of gravity between them is doubled. If the mass of one of the objects is tripled, then the force of gravity between them is tripled.

a ladder is resting as shown in the picture. if the mass of ladder is 5 kg and the length is 120 cm. Determine the Normal Force
Artyom0805 [142]

Answer:

17.64 N

Explanation:

Draw a free body diagram (see attached).  At the center of the ladder is weight pulling down.  At point C, we have a normal force pushing perpendicular to the ladder.  At point A, we have reaction forces in the x and y directions.

For simplicity, we can divide the normal force into x and y components.  The slope of the ladder is -80/60, so the slope of the normal force is 60/80.  Therefore:

Ny / Nx = 60 / 80

Ny / Nx = 3/4

Next, we'll take the sum of moments at point A:

∑τ = Iα

-Wd + Ny (60) + Nx (80) = 0

d is the horizontal distance between A and the center of the ladder.  We can find it using similar triangles.  From Pythagorean theorem, we know the distance between A and C is 100 cm.  So:

60 / 100 = d / 60

d = 36

-(5)(9.8)(36) + Ny (60) + Nx (80) = 0

60 Ny + 80 Nx = 1764

We now have two equations and two variables.  Solving:

60 (3/4 Nx) + 80 Nx = 1764

45 Nx + 80 Nx = 1764

125 Nx = 1764

Nx = 14.112

Ny = 3/4 Nx

Ny = 10.584

Using Pythagorean theorem to find N:

N = √(Nx² + Ny²)

N = 17.64

The magnitude of the normal force is 17.64 N.
