The total mechanical energy is the sum of the kinetic energy and the gravitational potential energy:

where m=3.5 kg is Candy's mass, v=1 m/s is her velocity and h=3.5 m is her height. If we replace these numbers, we find the mechanical energy of the system:
The resistance of the bulb when it is cold is

.
The resistance of the bulb when it is crossed by a current of I=0.4 A under a potential difference of

can be calculated by using Ohm's law:

The reason for this difference in the resistance is the following: when the current passes through the bulb, the bulb heats up, and an increase in temperature in the filament of the bulb causes an increase in resistance of the filament. In fact, the resistance of a resistor increases as the temperature increases, because the atoms of the lattice of the material vibrate more (due to their greater energy) and therefore the electrons of the current are more likely to collide with them. As a result, the resistance of the material increases.
Hello! I'm not too knowledgeable on this topic, but I do know that ammonification is caused through different inorganic reactions. Or to metabolism systems of organisms. I also found it is a process in which nitrate reduction to nitrite is followed by the six-electron reduction of nitrite to ammonium.
Answer:
v=18.97 m/s
Explanation:
the equation for the above question is v²=u²+2as
The wavelength of a photon of electromagnetic radiation with a frequency of 151.7 Mhz is 1.978 meter
According to the question
The frequency of a photon of electromagnetic radiation = 151.7 Mhz
By using the Formula of wavelength and frequency
λ = C/f
Where,
λ (Lambda) = Wavelength in meters
C = Speed of Light (c = 3x10⁸ m/s)
f = Frequency
Now, the wavelength of a photon of electromagnetic radiation with a frequency of 151.7 Mhz is
1 Mhz = 1000000 Hz
151.7 Mhz = 151.7 * 10⁶ Hz
λ = C/f
Substituting the value of C and f
λ =
λ = 1.978 meter
Hence, the wavelength of a photon of electromagnetic radiation with a frequency of 151.7 Mhz is 1.978 meter
