What accounts for the light and dark bands produced when monochromatic light reflects from a glass pane atop another glass pane?.
The waves that are reflected off the glass on the top and bottom surfaces of the air wedge interfere, which results in these bands. Interference between light waves reflected from the thin film's two sides.
Define monochromatic light.Electromagnetic radiation of a certain wavelength, whether visible or invisible, is monochromatic light.
Although in theory monochromatic light has exactly one wavelength, this is not practical, hence monochromatic light always comprises of a (relatively) narrow bandwidth of wavelengths. The color that the human eye can see when monochromatic light is in the visible spectral range is referred to as the spectral color. Lasers produce monochromatic light directly; a monochromator separates monochromatic light from a broadband light source.
Monochromatic light should only have one wavelength, according to theory. Monochromatic light is actually defined as having a narrow bandwidth.

Earth's equator receives more direct sunlight than the regions to its north and south. this distribution of sunlight accounts directly for which phenomenon
This happens because of the movement of rising air currents away from the equator.
Equator is an imaginary circle, which divides the Earth in half; while the Poles are the two points (the North Pole and the South Pole) that are crossed by the axis of rotation of the Earth. In Equator the temperature is hot, while in the Poles it is cold.
So when there is rising in the air currents movements away from the equator then whatever sunlight reflections or absorptions made by airs are reduced so in that area air density is less an sue to that sunlight is more present.

Tension force, Friction and gravity are acting on acrobat player while hanging in middle. and this is unbalanced force.
Tension is a contact force that is transmitted through a rope, thread, wire, or other similar material when pressures on the opposing ends tug on it. The rope that holds a tire swing to a tree branch is one such example. The rope is pulled upward by a branch tugging against the rope's tug tension, which is only a pulling force; the rope is dragged downward by gravity. Pushing on a slack rope will not cause it to be strained. As a result, the force of tension must always be represented in the direction that the string is pulling the object in a free-body diagram.

Demonstrate that change in heat cause change in temperature
Answer:
Procedure - Take 150g of ice in a beaker and suspend a laboratory thermometer so that the bulb is in contact with ice. Start heating and note the temperature when the ice starts melting. Finally, note the temperature when all the ice is completely melted.
Change in heat causes change in temperature because heat is the transfer of energy from a hotter object to a cooler object, leading to a change in the internal energy of the substance, which in turn affects its temperature.
When heat is added to a substance, its internal energy increases, and the particles in the substance gain kinetic energy, leading to an increase in temperature. The kinetic energy of the particles determines their motion, and as they move faster, the temperature of the substance rises.
Conversely, when heat is removed from a substance, its internal energy decreases, and the particles lose kinetic energy, resulting in a decrease in temperature. As the particles slow down, the temperature of the substance decreases.
The relationship between heat and temperature is described by the specific heat capacity of the substance, which quantifies the amount of heat required to raise the temperature of a given mass of the substance by one degree Celsius. In simple terms, heat is the energy transferred during a temperature change, and the two are intrinsically linked.
In summary, change in heat causes change in temperature because heat is the energy transferred that alters the internal energy of a substance, leading to changes in the kinetic energy and motion of its particles, resulting in temperature fluctuations.

When the proton starts to move upward the direction of the magnetic force changes and when the proton moves straight up the magnetic force turns to the left.
The direction of the force is perpendicular to the direction of the magnetic field and current, as given by Fleming's left-hand rule. Here the magnetic field is to the right and the direction of the current is upward. Protons feel a force on themselves due to the magnetic field. The force on the proton is proportional to the proton's magnetic flux density and velocity.
The velocity and momentum of a proton are affected by the force acting on it. If the velocity of a charged particle is perfectly parallel to the magnetic field, the magnetic field exerts no force on the particle, so the velocity remains constant. The momentum of a proton moving freely in a magnetic field is the product of the proton's mass and the proton's velocity. As the speed of a proton moving in a magnetic field changes, so does the momentum of the proton.

What is a theory?A theory can be defined as an integrated set of principles and rules that can be used by a scientist to explain and predict observed events.
According to Thomas Kuhn, the process of any scientific discovery usually starts with the awareness of an anomaly and ends with making an adjustment to scientific theory in order to make a previously anomalous to become expected.
What is the phlogiston theory?The phlogiston theory can be defined as a superseded scientific theory which stated that a fire-like materials (elements) referred to as phlogiston, are found within combustible bodies and they are released when burned or during combustion.
However, the phlogiston theory is an anomaly that was later overturned by a scientists known as Antoine Lavoisier in 1772, who proved that combustion and burning of any chemical substance or materials (elements) requires a gas that has mass.

what two basic measurements are taken to test insulation resistance? i. the actual leakage current flowing through the insulation. ii. the actual leakage current flowing through the conductor. iii. the actual resistance of the insulation. iv. the actual resistance of the conductor.
The insulation tester, often known as a Megger, is a device used to assess insulation resistance. For measuring insulating resistance, we utilise the following devices.
What is insulation resistance?
The insulation resistance of wires, cables, and electrical equipment is measured in ohms. It is critical to protect against electric shocks and to avoid equipment damage caused by inadvertent discharges. The insulating resistance is measured by testing and evaluating the status of the isolation (head and body.)
Direct indicating ohm metre with hand-operated DC generator
With direct indicating ohm metre and motor-driven DC generator
Direct indicating ohm metre with DC battery
Direct indicating ohm metre with a full-wave rectifier
Resistance bridge circuit with galvanometer and battery
The insulating resistance is measured using direct current voltage. We can create the DC voltage using a hand-driven dc generator or a motorised dc generator. Insulation functions as a capacitor. If the insulation quality is excellent, the capacitor will block the DC. Leakage current flowing through insulation shows inadequate insulation quality.
