What factors determine the distance at which two atoms form a bond ?
dsp73

Answer:

The length of the bond is determined by the number of bonded electrons (the bond order). The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length. Generally, the length of the bond between two atoms is approximately the sum of the covalent radii of the two atoms.

You weigh 716 newtons on Earth. You
Otrada [13]

Answer:

537 N

Explanation:

The force due to gravity of a planet is:

F = GMm / r²

where G is the universal gravitational constant

M is the mass of the planet

m is the mass of the object

and r is the distance between the object and the center of the planet

On Earth, you weigh 716 N, so:

716 N = GMm / r²

On planet X:

F = G (3M) m / (2r)²

F = 3/4 GMm / r²

F = 3/4 (716 N)

F = 537 N

An object on a vertical spring oscillates up and down in simple harmonic motion with an angular frequency of 14.2 rad/s. Calcula
zubka84 [21]

Answer:

0.04865 m

Explanation:

k = Spring Constant

m = Mass

d = Distance

g = Acceleration due to gravity = 9.81 m/s²

Angular frequency is given by

\omega=\sqrt{\dfrac{k}{m}}\\\Rightarrow \dfrac{k}{m}=\omega^2\\\Rightarrow \dfrac{k}{m}=14.2^2

At equilibrium we have

kd=mg\\\Rightarrow d=\dfrac{mg}{k}\\\Rightarrow d=\dfrac{g}{\omega^2}\\\Rightarrow d=\dfrac{9.81}{14.2^2}\\\Rightarrow d=0.04865\ m

The distance by which the spring stretches from its unstrained length is 0.04865 m

When a car maintains a velocity of exactly 65 mph, what is it's acceleration​
Readme [11.4K]

When a car maintains a velocity of exactly 65 mph, it's acceleration​ is zero.

<h3>What is acceleration?</h3>

The acceleration is time rate of change of velocity.

When the velocity is not changing with respect to time, it is said to be an object moving with constant velocity.

At constant velocity, there is no acceleration.

Thus, when a car maintains a velocity of exactly 65 mph, it's acceleration​ is zero.
