The carbon monoxide molecule (CO) consists of a carbon atom and an oxygen atom separated by a distance of

valkas [14]

Answer:

6.46*10^-11m

Explanation:

We can use the equation of the center of the mass of two atoms

$Xcm=\frac{mcxc+moxo}{mc+mo}$

If we take the origin at the center of the molecule carbon monoxice, xc will be 0, so

$Xcm=\frac{moxo}{mc+mo}$ = $\frac{xo}{mc/mo+1}$

$Xcm=\frac{1.13.10^-3}{0.750mo/mo+1}$ =6.46*10^-11m

two forces 3N and 4N act on a body in a direction due north and due East respectively calculate their equivalent

Lostsunrise [7]

Two forces 3N and 4N act on a body in a direction due north From East, the equilibrant's angle is given by $\theta=\tan ^{-1} \frac{3}{4}=36.8^{\circ}$ .

<h3>What are equilibrium and resultant force?</h3>

The equilibrium force is the balanced force when the net force acting is zero and is the exact opposite of the consequent force. The resultant force is one single force replaced by numerous forces.

<h3>Briefing:</h3>

3N and 4N are the two forces pulling on a body.

The forces work along the North and the East, which are perpendicular to one another.

The resultant of the forces, which is provided by the equilibrant force,

R = √(3)²+(4)²

R = 5N

From East, the equilibrant's angle is given by

$\theta=\tan ^{-1} \frac{3}{4}=36.8^{\circ}$

A 54 kg pole vaulter running at 10 m/s vaults over the bar. Her speed when she is above the bar is 1.3 m/s. The acceleration of

Marizza181 [45]

Answer:

$h_{B} = 5.012\, m$

Explanation:

It is assumed that pole vaulter began running at a height of zero. The physical model is formed after the Principle of Energy Conservation:

$K_{A} = K_{B} + U_{B}$

$\frac{1}{2} \cdot m \cdot v_{A}^{2} = \frac{1}{2} \cdot m \cdot v_{B}^{2} + m \cdot g \cdot h_{B}$

The previous expression is simplified and required height is found:

$h_{B} = \frac{1}{2\cdot g} \cdot (v_{A}^{2}-v_{B}^{2})$

$h_{B} = \frac{1}{2 \cdot (9.807\, \frac{m}{s^{2}} )} \cdot [(10\, \frac{m}{s} )^{2}-(1.3\, \frac{m}{s} )^{2}]$

$h_{B} = 5.012\, m$

How does the position of an object relate to the energy stored in an object?

Kamila [148]

Answer:

Potential Energy

Explanation:

Potential energy is the energy stored in an object due to it's position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.
