How does a rubber rod become negatively charged through friction?

The correct answer to the question is C) It is rubbed with another object, and electrons move onto the rod.

EXPLANATION:

Before going to answer this question, first we have to understand the charging by friction.

Charging by friction is one mode of charging a body by rubbing it with another body in which there will be actual transfer of electrons from one body to another body.

In this process, the electrons will be transferred from a low affinity body to a high affinity body. The high electron affinity body will be negatively charged as it accepts electron, and the low electron affinity body will be positively charged.

As per the question, the charge of rubber rod is negative. Hence, it must have rubbed with another object, and electrons move onto the rod.

The protons can not move onto the rod as protons are bound to the nuclei of atoms.

If the car in the opposite direction turns the signal on your vehicle, then it is only likely to give way and let him or her turn before you make your turn because he or she is in the right of way and by doing this, it will prevent any complication from happening and to be able to show respect and politeness in driving.

The lowest point in Death Valley is 75.5 m below the sea level. The summit of nearby Mt. Whitney has an elevation of 4360 m. Wha
sineoko [7]

Answer:2738.477 kJ

Explanation:

Given

Lowest Point of death valley is 75.5 m below sea level

Height of Mt. Whitney is 4360 m

mass of hiker =63 kg

Change in potential energy=m\times g\times (h_2-h_1)

Considering sea level a datum

\delta PE=63\times 9.8\times (4360-(-75.5))=2738477.7 J

\delta PE=2738.477 kJ

What is the difference between how transverse waves and longitudinal waves move particles
zysi [14]

A wave on a string is the classic example of a transverse wave. Each part of the string moves up and down while the wave moves from side to side. Transverse waves can not happen in gases because the perpendicular motion is not created by any force.

A Slinky is a great way to visualize longitudinal waves. Each part of the Slinky moves from side to side, just like the wave itself.

Sound waves are longitudinal pressure waves in the air. Water waves involve a combination of transverse and longitudinal waves. The water moves up and down, but also back and forth. Each particle in the water ends up moving in a circular fashion. Earthquakes also have different kinds of waves. The primary waves, called P waves, move with the highest velocity and are transverse waves. Secondary waves, called S waves, are longitudinal waves and occur seconds after the primary waves.

Answer: I’m pretty sure it’s genetic information.

Explanation: Genetic information is passed from generation to generation through inherited units of chemical information (in most cases, genes). Organisms produce other similar organisms through sexual reproduction, which allows the line of genetic material to be maintained and generations to be linked.
