B . Because cardiovascular has everything to do with your heart how the blood flows and pumps and all that good stuff .

B. This is the focus of the hope when exercising. If these things are not 'up to par', then you will not excel physically.

Gravity Force (Fgray) is __.

polet [3.4K]

The force of gravity is an attractive force, whose magnitude is given by $F=G\frac{m_1 m_2}{r^2}$

Explanation:

The force of gravity is one of the four fundamental forces of nature (the weakest one). It is an attractive force that is exerted between every object that has mass.

The magnitude of the gravitational force between two objects is given by the equation:

$F=G\frac{m_1 m_2}{r^2}$

where :

$G=6.67\cdot 10^{-11} m^3 kg^{-1}s^{-2}$ is the gravitational constant

$m_1, m_2$ are the masses of the two objects

r is the separation between them objects

We notice from the equation that:

- The gravitational force is proportional to the product of the masses: so if the masses increase, the force will increase as well

- The gravitational force is inversely proportional to the square of the distance: so if the distance increases, the force will decrease

Which example best represents translation kinetic energy

Alex777 [14]

Example? I see none, so I'll make up my own.
An example of kinetic energy, is like bicycle riding down a hill.
Kinetic energy, is basically <em>moving</em> energy.
Hope this helps!!!:)

If a ball is rolled down a frictionless inclined plane from a height of 3 feet, to what height would it roll up to on the other

mojhsa [17]

Answer:

It will roll up to its initial height from which it rolled from on the first hill

Explanation:

The given information are;

The height from which the ball is rolled = 3 feet[

The equation of the potential energy of the ball as it rolled down the frictionless inclined plane is given by the following equation;

m × g × h₁ = 1/2 × m × v² + 1/2×[2/5× m × r²) × [v/r]

Where;

m = The mass of the ball

h = The from which the ball is rolled down

v = The velocity of the ball

r = The radius of the ball

Therefore, all the potential energy, m × g × h, is converted into kinetic energy when the ball reached the ground

Similarly, as the ball rolls up on the other side, by the principle of energy conservation, all the kinetic energy is transformed into potential energy as follows

1/2 × m × v² + 1/2×[2/5× m × r²) × [v/r] = m × g × h₂, therefore, we have;

1/2 × m × v² + 1/2×[2/5× m × r²) × [v/r] = m × g × h₁ = m × g × h₂

Therefore since m × g × h₁ = m × g × h₂, then h₁ = h₂, the ball rises to the same height it started rolling from on the first hill.

A car travels 60 km in the first 2 hours and 68 km in the next 2 hours.

ZanzabumX [31]

Answer:32km/hr

Explanation:

Speed=distance/time

Speed=60/2 =30km/hr speed=68/2=34km/he

Average speed=(30+34)/2 =64/2=32km/hr
