Answer:
Momentum, p = 7.2 g-m/s
Explanation:
It is given that,
The momentum of an object is 
We need to express momentum in any equivalent units. There can be many solutions of this problem. Some of the units of mass are gram, milligram etc. units of length are meters, mm etc.
Since, 1 kg = 1000 gram
So, 
Therefore, the momentum of the object is 7.2 g-m/s. Hence, this is the required solution.
Answer:
Time interval for which magnetic field reduced to ZERO is given as
Explanation:
As we know that the flux linked with one coil is given as
now total flux of all coils is given as
now let say the flux is reduced to ZERO after time "t"
so as per Faraday's law EMF induced in the coil is given as
now the current in the coil is given as
so the time interval is given as
Explanation:
average speed is the total distance divided by total time
Mass of an electron = 9.110 x 10⁻³¹ kg.
Mass of a proton = 1.6727 x 10⁻²⁷ kg
∴ mass of a proton/mass of an electron = 1.6727 x 10⁻²⁷ kg/9.110 x 10⁻³¹ kg.
~1836
∴ mass of a proton = 1836 x mass of an electron.
∴ mass of an electron is insignificant to the mass of an atom.
∴mass of an atom = mass of protons + mass of neutrons
The flow of electricity in a certain path is the circuit.
