Explanation:
To find the answer use the equation speed of light=wavelength multiplied by frequency (c=lambda*f) by substituting the value for the frequency the the speed of light
Actually the
Kinetic Energy, which is also known as the energy of motion is directly
proportional to temperature. So the higher the temperature is, the faster the gas
particles move so they have possess more kinetic energy.
This temperature is in
absolute units so we convert to Kelvin:
200 C = 473.15 K
100 C = 373.15 K
So the amount increase
is:
473.15 / 373.15 =
1.268
<span>It will increase by a
factor of 1.268 or 126.8%</span>
The answer is D. Mountains in North America appear to be the same as those in Northern Europe
Answer:
<em>The drop voltage is 0.3 V</em>
Explanation:
Electromotive Force EMF
When connecting a battery of internal resistance Ri and EMF ε to an external resistance Re, the current through the circuit is:
The battery has an internal resistance of Ro=2 Ω, ε=24 V and is connected to an external resistance of Re=158 Ω. Thus, the current is:
i = 0.15 A
The drop voltage is the voltage of the internal resistance:
The drop voltage is 0.3 V
