By transferring electrical charges from one object to another

Explanation:

The law of conservation of electric charge states that the total electric charge of the universe is constant, therefore no charge can be created or destroyed, but only transferred.

Indeed, when an object is charged, this is due to the fact that charge carriers (typically electrons) are transferred to/from the object.

Consider an object initially neutral: this means that the object has initially an equal amount of positive charges (protons) and negative charges (electron).

Later, if we remove electrons from the object, then it will remain with an excess of protons: therefore, it will be positively charged. However, the electrons have not disappeared: simply, they have been moved somewhere else (on another object, for example, which will become negatively charged: so, the total net charge will still be zero).

Similarly, if we add electrons to the object, it will become negatively charged: however, the electrons have been removed from another object which is now positively charged, so the net charge still has not changed.

Answer:

The answer is: Increase the Number of Ropes/Pulleys.

Explanation:

A "pulley" <u><em>is an object that supports a particular movement such as supporting a force's change in direction (provided that the direction is applied to a cord). </em></u>This is regarded as a "simple machine" consisting of a wheel on an axle. This helps guide cables or ropes.

This machine is used <em>in order to decrease the amount of time it takes to do work, such as lifting of objects.</em>

Remember that "mechanical advantage"<u> refers to the ratio between the force applied to a machine and the force produced by it.</u> So, when it comes to pulleys, the mechanical advantage increases when the number of ropes are also increased. They are directly proportional. This goes the same way with increasing the number of pulleys. Once you increase the number of pulleys, the mechanical advantage also increases.

Which two options are forms of kinetic energy?
juin [17]

Answer:

B. Thermal energy

E. Sound energy

Explanation:

Thermal and sound energy is kinetic energy.

Kinetic energy is the energy that results as a function of the motion of a body or the particles of the medium.

Sound energy is transmitted by the vibration of the particles in the air. The vibration leads to movement of the particles and hence, kinetic energy is produced.

Thermal energy originates as a result of the temperature differences in a body. This temperature difference leads to the increase in the kinetic energy of some particles which also causes vibration and motion of the particles.

Eq-48 when operating your vessel with a vhf radio, what channel must you monitor?
77julia77 [94]

VHF Channel 16 must always be monitored. It is the calling and distress channel. This is where the operator might hear a MAYDAY call. This is also where the operator can issue a MAYDAY. Improper misuse of the channel can result to penalties.
