Why can a molecule contain polar bonds be non polar overall?

brilliants [131]

The overall atom is non-polar because there are two negatively charged sides instead of one positive side and one negative side.

Some gas molecules move at speeds of 542 meters per second. How fast is this in miles per hour? 542 =? 1h Solve by dimensional a

artcher [175]

Answer:

$1212.42\ \text{mph}$

Explanation:

We need to convert $542\ \text{m/s}$ to $\text{miles/hour}$

$1\ \text{mile}=5280\ \text{ft}$

$1\ \text{ft}=12\ \text{inches}$

$5280\ \text{ft}=5280\times 12=63360\ \text{inches}$

$1\ \text{inch}=2.54\ \text{cm}=0.0254\ \text{m}$

$63360\ \text{inches}=63360\times 0.0254=1609.344\ \text{m}$

$1\ \text{mile}=1609.344\ \text{m}\\\Rightarrow 1\ \text{m}=\dfrac{1}{1609.34}\ \text{miles}$

$1\ \text{hour}=60\times 60\ \text{seconds}\\\Rightarrow 1\ \text{s}=\dfrac{1}{3600}\ \text{hour}$

$542\ \text{m/s}=\dfrac{\dfrac{542}{1609.34}}{\dfrac{1}{3600}}=1212.42\ \text{mph}$

The speed of the gas molecules is $1212.42\ \text{mph}$ .

The maximum kinetic energy of a box sliding from the top of a ramp to the bottom is A) at the top. B) at the bottom. C) at the e

Readme [11.4K]

Kinetic energy of an object can be expressed in terms of its mass m and velocity v as:

KE = 1/2 * m* v²

Thus higher the velocity, greater will be the Kinetic energy. Now, as the box moves along a ramp from top to bottom, its velocity increases and so does the KE. Hence, kinetic energy is maximum at the bottom

Ans B) at the bottom
