10^9 h ye

Vansh Prajapati 5 years, 1 month ago

Charge of one electron= 1.6×10^-19 C Charge of 10^9 electrons = 1.6×10^-19 C × 10^9 = 1.6×10^-10 C We can say,1.6×10^−10 C of charge move out of the body to another body every second. The time required to get a total charge of 1C = 1sec/1.6×10^-10 C = 6.25×10^9 / 365×24×3600 = 197.8 years or approximately 198 years.

Charge of one electron= 1.6×10^-19 C

Charge of 10^9 electrons = 1.6×10^-19 C × 10^9

= 1.6×10^-10 C

We can say,1.6×10^−10 C of charge move out of the body to another body every second.

The time required to get a total charge of

1C = 1sec/1.6×10^-10 C

= 6.25×10^9 / 365×24×3600

= 197.8 years or approximately 198 years.

The current flowing through the circuit is given as: I=E/(r+R), where r is the internal resistance of the cell and R is the external resistance. Maximum current can be drawn only when external resistance is zero. Hope It Helps You?

Gaurav Seth 5 years, 1 month ago

In a circuit the current flowing through the circuit is given as :
I=E/(r+R)
Where r is the internal resistance of the cell and R is the external resistance.
Maximum current can be only drawn when external resistance is zero.

Protons are found in the nucleus of the atom. This is a tiny, dense region at the center of the atom. Protons have a positive electrical charge of one (+1) and a mass of 1 atomic mass unit (amu), which is about 1.67×10−27 kilograms.

Yogita Ingle 5 years, 1 month ago

Proton is a positively charged particle and has the following physical properties:

  1. Mass of Proton – The mass of a proton is equal to that of the hydrogen atom. A hydrogen atom consists of one electron and one proton. As the mass of an electron is considered to be negligible therefore it can be said that the mass of hydrogen atom is equal to the mass of a proton. The mass of a proton is 1840 times the mass of an electron.
Mass of proton = 1.676 × 10-27 kg = 1.676 × 10-24 g = 1.6726219 × 10-27 kg
  1. Charge of Proton – The charge of a proton is equal to and opposite to that of an electron. Thus, it has a unit positive charge.
Charge on a proton = + 1.602 × 10-19 coulombs

The dual nature of matter and the dual nature of radiation were revolutionary concepts of physics. At the beginning of the twentieth century, scientists unravelled one of the best-kept secrets of nature – the wave particle duality or the dual nature of matter andradiation. Everything is a wave and a particle!

Earth’s Magnetism is generated by convection currents of molten iron and nickel in the earth’s core. These currents carry streams of charged particles and generate magnetic fields. This magnetic field deflects ionising charged particles coming from the sun (called solar wind) and prevents them from entering our atmosphere. Without this magnetic shield, the solar wind could have slowly destroyed our atmosphere preventing life on earth to exist. Mars does not have a strong atmosphere that can sustain life because it does not have a magnetic field protecting it.

The earth’s magnetic poles are not aligned to the actual geographic north and south poles. Instead, the magnetic south pole is in Canada while the magnetic north pole lies in Antarctica. The magnetic poles are inclined by about 10 degrees to the earth’s rotational axis. So, all this time your compass was really pointing to Canada, not the true North.

There are four universal or fundamental forces in nature. Without these forces, all matter in the world will fall apart. Force as such is any pull or push that causes an object to alter its physical state (in terms of motion or deformity). Newton defined a force as anything that causes an object of mass ‘m’ to move with an acceleration ‘a’. Following are the four fundamental forces in nature:

  • Gravitational force
  • Electromagnetic force
  • Strong nuclear force
  • Weak nuclear force

emf is the potential difference between terminals of cells if its internal resistance is 0. It can also be defined as the work done in moving unit test charge from one terminal of cell to another in case its internal resistance is neglected.

Voltmeter is an measuring device with high resistance which measures the potential difference in volts of the circuit connected in parallel. It do not affected the current flow in the circuit. It is symbolically represented as 'V'. It is use for measuring potential difference and voltage ranges between two ends of circuit.
