Answer:
From frequency=speed of wave/frequency
=3×10^8÷1.18×10^-7
Frequency=2.5×10^15s-
Energy=plank × frequency
Energy=16.175×10^-19js-
Explanation:
If the engineers are trying to increase the acceleration of the car, they have to decrease the mass of the car.
<h3>What is Newtons law?</h3>
The Newtons laws of motion form the basis of the discussion about motion. We know that from the second law of Newton F = ma

<em>The</em><em> </em><em>heat</em><em> </em><em>required</em><em> </em><em>to</em><em> </em><em>convert</em><em> </em><em>25</em><em> </em><em>grams</em><em> </em><em>of</em><em> </em><em>-10</em><em> </em><em>°</em><em>C</em><em> </em><em>steam</em><em> </em><em>is</em><em> </em><em>783</em><em>6</em><em>0</em><em> </em><em>J</em><em> </em><em>or</em><em> </em><em>78.36</em><em> </em><em>kJ</em><em>.</em>
Potassium sulphate = K2SO4
molecular weight = 40*2 +32 +4*16 = 176
Molarity = moles of solute / volume in L
1.34 = x/176 *1000/ 115
x = 1.34*176*115/1000
x=27.1216g
Glacial striations show the direction a glacier is moving, and it suggests that the glacier flowed from a single location.
