Mercury and Venus are therefore closer to each other most of the time. But Earth is the planet closest to Venus. And that's why from here on Earth, Venus looks so big and luminous. Venus is the brightest thing in the night sky after the sun and the moon.
The force which has the greatest effect on causing this object to slow while it remains in contact with the ramp is: B. a frictional force.
<h3>What is a force?</h3>
A force can be defined as a push or pull of an object or physical body, which typically results in a change of motion (acceleration), especially due to the interaction of the object with another.
<h3>The types of force.</h3>
In Science, there are different types of force and these include the following:
<h3>What is a
frictional force?</h3>
Friction force can be defined as a type of force that resists and slows the relative motion of two physical objects when there surfaces come in contact. This ultimately implies that, a frictional force prevents two surfaces from easily sliding over or slipping across one another.
In this context, we can infer and logically deduce that the force which has the greatest effect on causing this object to slow while it remains in contact with the ramp is a frictional force.

B. a frictional force
C. the force due to gravity
D. a force of air resistance
The top plate grew more positively charged as the voltage was raised, while the bottom plate became more negatively charged. Accordingly, the electron moves from the top plate to the bottom plate.
<h3 /><h3>What is a voltage?</h3>
When charged electrons (current) are forced through a conducting loop by the pressure of an electrical circuit's power source, they can perform tasks like lighting a lamp.
In a nutshell, voltage equals pressure and is expressed in volts (V). The name honours Alessandro Volta (1745–1827), an Italian physicist who developed the voltaic pile, the precursor of the modern household battery.
Early on, voltage was referred to as electromotive force (emf). This is the reason why the symbol E is used to denote voltage in equations like Ohm's Law.
The words "potential difference" and "voltage" are frequently used interchangeably. The potential energy difference between two places in a circuit might be a better way to define potential difference. How much potential energy there is to transport electrons from one specific place to another depends on the differential (measured in volts). The amount indicates the maximum amount of work that could possibly be done through the circuit.
For instance, a standard AA alkaline battery provides 1.5 V. Electrical outlets seen in most homes provide 120 V. The more electrons a circuit can "push" and do work with, the higher the voltage in the circuit.

Concept:
Wave: It is the disturbance in which the energy is transferred from one place to another place. During the propagation of the wave, medium particles do not move. They vibrate at their position in to and fro form.
In case of the Transverse wave, medium particles vibrate perpendicular to the direction of the wave while in case of Longitudinal wave, they vibrate along the direction of the wave.
Hence, the best definition of the wave will be the disturbance that transfers the energy from one place to another place.
