Temperature is a measure of the energy of molecules and energy is related to speed.
<span>The water in a pot is heated by convection. The water on the bottom will warm up and rise toward the surface and the cooler water will then sink to the bottom where it will be heated. </span>
<span>Oxygen will form ionic bonds with nitrogen. The others will not by themselves. </span>
<span>A high pH is indicative of a basic solution. HCl and H2SO4 are both strong acids and will result in a lower (more acidic) pH. Water is the standard. KOH is a strong base and will increase the pH. </span>
<span>An acidic solid will lower the pH of a solution. pH measures the number of hydrogen ions and a lower pH will mean that there are more H+ ions, but the solid could just have reacted with the OH- to cause the pH to decrease</span>
Answer:
a
b
Explanation:
From the question we are told that
The mass of the person is
The speed of the person is
The energy of the proton is
Generally the de Broglie wavelength is mathematically represented as
Here h is the Planck constant with the value
So
=>
Generally the energy of the proton is mathematically represented as
Here is the mass of proton with value
=>
=>
=>
So
so
=>
Answer:
dV/dt = 9 cubic inches per second
Explanation:
Let the height of the cylinder is h
Diameter of cylinder = height of the cylinder = h
Radius of cylinder, r = h/2
dh/dt = 3 inches /s
Volume of cylinder is given by
put r = h/2 so,
Differentiate both sides with respect to t.
Substitute the values, h = 2 inches, dh/dt = 3 inches / s
dV/dt = 9 cubic inches per second
Thus, the volume of cylinder increases by the rate of 9 cubic inches per second.
