Explanation:

Define: Signals

Before going too much further, we should talk a bit about what a signal actually is, electronic signals specifically (as opposed to traffic signals, albums by the ultimate power-trio, or a general means for communication). When one speaks of analog one often means an electrical context, however mechanical, pneumatic, hydraulic, and other systems may also convey analog signals.

An analog signal uses some property of the medium to convey the signal's information. Any information may be conveyed by an analog signal, often such a signal is a measured change in physical phenomena, such as sound, light, temperature, position, or pressure.

For example, in sound recording, changes in air pressure (that is to say, sound) strike the diaphragm of a microphone which causes related changes in a voltage or the current in an electric circuit. The voltage or the current is said to be an "analog" of the sound.

A skier starts from rest and accelerates down a slope 2 at 23 m/s^2. How much time required for the skier to reach a speed of 9.
gayaneshka [121]

The skier's speed at time <em>t</em> is

<em>v</em> = (23 m/s²) <em>t</em>

To reach a speed of 9.3 m/s, the skier would need

9.3 m/s = (23 m/s²) <em>t</em>

<em>t</em> = (9.3 m/s) / (23 m/s²)

<em>t</em> ≈ 0.404 s

Approximately how much electrical energy does a 5-W lightbulb convert to radiant and thermal energy in one hour?​
k0ka [10]

Answer:

18,000 j

Explanation:

the lightbulb dissipates 5W of power

P = ΔE / Δt

rearrange to solve for energy

ΔE = PΔt

P = 5W

t =  1 hour = 60 minutes = 3600 seconds

ΔE = 5 * 3600

ΔE = 18000 J
