A student claims that signals transmitted by wireless computer networks are more beneficial than signals transmitted by other devices. Which statement supports the student’s claim? The wireless computer networks transmit signals that human beings can sense directly.

Signals do not need digitalization for long-distance transmission.

The wireless signals can carry large amounts of data at high radio frequencies.

Signals are transmitted at lower radio frequencies to reduce loss of data.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
