Since everything in the circuit is in series .. .
-- The total resistance is (3 + 2) = 5 ohms.
-- The voltage across the 3-ohm resistor is 3/5 of the total voltage.
-- The voltage across the 2-ohm resistor is 2/5 of the total voltage.
(2/5) of (9 volts) = 18/5 = 3.6 volts .
Cars are the mechanical device which convert chemical energy of fuel into mechanical energy, the engine used in the automobiles car are very inefficient, they can only convert 30-40% of chemical energy of fuel into mechanical energy, since thermodynamics is the branch of science that deals with the conversion of energy, thus due to poor conversion rate of chemical energy into mechanical energy, cars are known as inefficient machine.
Answer:
Electrons are located in specific orbit corresponding to discrete energy levels
Explanation:
In Bohr's model of the atom, electron orbit the nucleus in specific levels, each of them corresponding to a specific energy. The electrons cannot be located in the space between two levels: this means that only some values of energy are possible for the electrons, so the energy levels are quantized.
A confirmation of Bohr's model is found in the spectrum of emission of gases. In fact, when an electron jumps from a higher energy level to a lower energy level, it emits a photon whose energy is exactly equal to the difference in energy between the two levels: since the energy levels are discrete, this means that the emitted photons cannot have any value of wavelength, but also their wavelength will appear as a discrete spectrum. This is exactly what it is observed in the spectrum of emission of gases.
Where are the questions so that I can deliver a more accurate answer.
Answer:
a. ![i=4760 kg*m/s](https://tex.z-dn.net/?f=i%3D4760%20kg%2Am%2Fs)
b. ![D_U= 1.11 m](https://tex.z-dn.net/?f=D_U%3D%201.11%20m)
Explanation:
a)
F= 120,000N
Kinetic energy @ impact = 120,000*depth
![K_E=133280 J](https://tex.z-dn.net/?f=K_E%3D133280%20J)
![D_U= \frac{133280J}{120000N} = 1.11 m](https://tex.z-dn.net/?f=D_U%3D%20%5Cfrac%7B133280J%7D%7B120000N%7D%20%3D%201.11%20m)
b)
The momentum is equal to the impulse on him from the snow so:
![p=m*v](https://tex.z-dn.net/?f=p%3Dm%2Av)
![p=85kg*56m/s](https://tex.z-dn.net/?f=p%3D85kg%2A56m%2Fs)
![i=4760 kg*m/s](https://tex.z-dn.net/?f=i%3D4760%20kg%2Am%2Fs)
