Explain Newton's first law and create a real world scenario where the law is being used
ASHA 777 [7]

Answer:

Newton's first law is a object at rest stays at rest unless acted by and outside force

Explanation:

say there is a ball sitting still it is at rest well say a kid comes over and kicks the ball the kid is the outside force that puts the ball in motion so the ball goes from sitting still to moving by the outside force also known as the kid

Mrac [35]
When two substances at different tempeartures como into contact, the substance that is at higher temperature will transfer energy, in the form of heat, to the substance that is at lower temperature, until their temperatures get equal.

In this case, if the two substances are isolated of the rest of the universe, the law of conservation of energy states tha the heat released by the substance initially at higher temperature is the same amount of heat gained by the substance originally at lower temperature.

Calculate the shortest wavelength of light capable of dissociating the Cl–F bond in one molecule of chlorine monofluoride if the
Fofino [41]

Answer:

477 nm

Explanation:

Using the expression for the energy as:

E=\frac {h\times c}{\lambda}

Where,  

h is Plank's constant having value 6.626\times 10^{-34}\ Js

c is the speed of light having value 3\times 10^8\ m/s

\lambda is the wavelength of the light

Given, Energy=251\ kJ/mol=251000\ J/mol

Also, N_a=6.023\times 10^{23}\ {mol}^{-1}

So, Energy for one atom = \frac{251000}{6.023\times 10^{23}}\ J

Thus, applying values as:

\frac{251000}{6.023\times 10^{23}}=\frac{6.626\times 10^{-34}\times 3\times 10^8}{\lambda}

251\times \:10^{26}\lambda=5^{20}\times \:125540965

\lambda=4.77\times 10^{-7}\ m=477\times 10^{-7}\ m=477\ nm

( 1 m = 10^{-9} nm )
