English: Cardiovascular efficiency depends on a number of factors. One measure is called stroke volume, which is the volume of blood pumped per heartbeat. A fit individual has a larger stroke volume, which means a greater volume of oxygen is delivered to the body per heartbeat.
Spanish: La eficacia cardiovascular depende de una serie de factores. Una medida se denomina volumen sistólico, que es el volumen de sangre bombeada por latidos cardíacos. Un individuo en forma tiene un volumen de movimiento mayor, lo que significa que un mayor volumen de oxígeno es entregado al cuerpo por latidos cardíacos.
Answer:
The vertical distance is ![d = \frac{2}{k} *[mg + f]](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7B2%7D%7Bk%7D%20%2A%5Bmg%20%2B%20f%5D)
Explanation:
From the question we are told that
The mass of the cylinder is m
The kinetic frictional force is f
Generally from the work energy theorem
![E = P + W_f](https://tex.z-dn.net/?f=E%20%20%3D%20%20P%20%2B%20%20W_f)
Here E the the energy of the spring which is increasing and this is mathematically represented as
![E = \frac{1}{2} * k * d^2](https://tex.z-dn.net/?f=E%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%2A%20k%20%20%2A%20%20d%5E2)
Here k is the spring constant
P is the potential energy of the cylinder which is mathematically represented as
![P = mgd](https://tex.z-dn.net/?f=P%20%20%3D%20mgd)
And
is the workdone by friction which is mathematically represented as
![W_f = f * d](https://tex.z-dn.net/?f=W_f%20%20%3D%20%20f%20%2A%20%20d)
So
![\frac{1}{2} * k * d^2 = mgd + f * d](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%2A%20k%20%20%2A%20%20d%5E2%20%3D%20%20mgd%20%2B%20%20f%20%2A%20%20d%20)
=> ![\frac{1}{2} * k * d^2 = d[mg + f ]](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%2A%20k%20%20%2A%20%20d%5E2%20%3D%20%20d%5Bmg%20%2B%20%20f%20%20%20%20%5D)
=> ![\frac{1}{2} * k * d = [mg + f ]](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%2A%20k%20%20%2A%20%20d%20%3D%20%20%5Bmg%20%2B%20%20f%20%20%20%20%5D)
=> ![d = \frac{2}{k} *[mg + f]](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7B2%7D%7Bk%7D%20%2A%5Bmg%20%2B%20f%5D)
Answer:
4.4 cm
Explanation:
Given:
Distance of the screen from the slit, D = 1 m
Distance between two third order interference minimas, x = 22 cm
Let's say, minima occurs at:
![x_n = (n + \frac{1}{2}) \frac{wL}{d}](https://tex.z-dn.net/?f=%20x_n%20%3D%20%28n%20%2B%20%5Cfrac%7B1%7D%7B2%7D%29%20%5Cfrac%7BwL%7D%7Bd%7D)
We have:
![2x_2 = 2(2 + \frac{1}{2}) * \frac{w*22}{d}](https://tex.z-dn.net/?f=%202x_2%20%3D%202%282%20%2B%20%5Cfrac%7B1%7D%7B2%7D%29%20%2A%20%5Cfrac%7Bw%2A22%7D%7Bd%7D%20)
Calculating further for the width of the central bright fringe, we have:
![\frac{w}{d} = \frac{22}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bw%7D%7Bd%7D%20%3D%20%5Cfrac%7B22%7D%7B5%7D%20)
= 4.4 cm
Note: w in representswavelength
Yes that's a true statement. That's why grandmother put a hot water bottle to warm up her bed, and not a hot bar of steel or lead.
