Answer:
55 ohms
Explanation:
if it was series circuit, then you just need to add all the resistances
b 0.013 m
c 130 m
d 76.92 m
Answer:
Option C is the correct answer
Explanation:
We have equation of motion , , s is the displacement, u is the initial velocity, a is the acceleration and t is the time.
In this case initial velocity = horizontal velocity = 100 m/s, acceleration = 0 , we need to calculate displacement when time = 1.3 seconds.
Substituting
So, bullet will travel a distance of 130 meter in 1.3 seconds.
Option C is the correct answer
2. They both need to gain one electron.
3. Sodium needs to lose one electron, and chlorine needs to gain one electron.
4. Sodium needs to gain one electron, and chlorine needs to lose one electron.
Answer: The correct option is (3) " Sodium needs to lose one electron, and chlorine needs to gain one electron ".
Explanation :
The electronic configuration of sodium (Na) is . It has only one vacant electron.
While the electronic configuration of chlorine is . It has seven valance electrons.
When Na reacts with Cl, Na will lose one electron and this lost electron gets transferred to chlorine. This forms a strong ionic bond.
So, the correct option is (3) " Sodium needs to lose one electron, and chlorine needs to gain one electron ".
B. Be in phase with each other
C. Have a different frequency than the resultant wave
D. Be traveling in the opposite direction of the resultant wave
Correct answer choice is:
B. Be in phase with each other.
____________________________________________________________
Explanation:
Components waves mix to produce a resultant with the equivalent wavelength but the amplitude which is bigger than the amplitude of both of the unique component waves, and this results in constructive interference, which states that the interference of two or more waves of identical frequency and phase, constructing in their respective reinforcement and constructing a single amplitude equivalent to the total of the amplitudes of the unique waves.
Each particle exists inside an atom.
Each particle has an electrical charge.
Each particle is located in the nucleus.
The correct answer to this question is B) Each particle exists inside an atom.
EXPLANATION:
Before going to answer this question , first we have to understand the nature of electron and neutron.
Electrons and neutrons are the subatomic particles which are present inside the atom.
Electron is that subatomic particle which is present in the extra nuclear part of the atom, and it moves around the nucleus in different permitted, stationary orbits. The charge of electron is negative.
The neutron is that subatomic particle which is present in the nuclear part of the atom along with protons. The charge of proton is positive and the neutron is neutral in nature.
Hence, the correct option of this question is that both electrons and neutrons are present inside the atom.
