The particle’s direction is always relative to the lines of the electric field.

The positively charged particles are called alpha rays. An alpha particle is a helium atom with two protons and neutrons that is extremely energetic and active. These particles are the most ionizing and have the least penetration power. Because of their strong ionization power, they have the potential to seriously harm the body if they enter. They can ionize a large number of atoms at close range. They are more intense than others because they create a significant transition from n=1 to n(target).

The process by which unpolarized light becomes polarized is known as polarization of light. Only one plane is vibrated by polarized light. The magnetic and electric components of light waves vibrate perpendicular to each other, making them transverse waves. Light only vibrates in one plane when it is polarized. Therefore, light’s polarization indicates that it is electromagnetic.

Since there is no heat exchange in an adiabatic process, the internal energy would only depend on the work that is done by the system or on the system itself.

We must consider every option while attempting to determine which fits the circumstances because the situation isn’t stated clearly. Option A is adiabatic expansion, in which the system performs the work. The system donates energy to carry out work because it needs energy to do it, which lowers internal energy.

One H2O molecule has an average mass of 18.02 amu. Both the number of atoms and the number of moles are precise numbers that have no bearing on the number of significant figures. One mole of H2O weighs 18.02 grams on average. The molar mass of water is 18.02 g/mol, or 0.018 kg/mol, according to the statement.

Area of the cross-section A=π(d/2)2=π(0.05 mm/2)2=π×0.0025mm2 /4 ≈0.00196 mm2
This wire has the smallest cross-sectional area because it has the smallest diameter of any of the available options. As a result, under the same tension, it will extend to its maximum.

When a charged particle travels through a magnetic field, it feels a force. A charged particle travels in a curved path in a magnetic field because the magnetic force is perpendicular to the direction of travel. This curved path is followed by the particle until it completes a circle.
