A boat travels 105 km downstream in 5 hours. The return trip upstream takes 7 hours. Find the speed of the boat in still water a
notsponge [240]
Speed of the boat = u
speed of the current = v

in downstream,
u - v = 105/5
u - v = 21

in upstream
u + v = 105/7
u + v = 15

add both equations
2u = 36
u = 18

v = -3

so
speed of the boat = 18 km/h
speed of the current = 3 km/h

Determine the decibel values of thermal noise power (N) and thermal noise power density (No) given the following: T=292 degrees
Agata [3.3K]

Answer: d. None of the above are correct.

Step-by-step explanation: Noise is a superfluous random alteration in an eletrical signal. There are different types of noises created by different devices and process. Thermal noise is one of them. It is unavoidable because is created by the agitation of the charge carriers, due to temperature, inside an eletrical conductor at equilibrium and is present in all eletrical circuits.

The formula to find the thermal noise power (N) is: N = k_{b}.T.B, where:

k_{b} is Boltzmann constant (1.38.10^{-23}J/K);

T is temperature in Kelvin;

B is the bandwith;

Calculating the thermal noise power:

N = 1.38.10^{-23}·292·40

N = 16118.4.10^{-23} dBm

The thermal noise power [N] = 16118.4.10^{-23} dBm

Noise power density or simply Noise density (N₀) is the noise power per unit of bandwith and its SI is watts per hertz.

For thermal noise, N₀ = kT, where

<em>k </em>is the Boltzmann constant in J/K;

T is the receiver system noise temperature in K;

N₀ = 1.38.10^{-23} . 292

N₀ = 402.96.10^{-23} W/Hz

The thermal noise power density [N₀] = 402.96.10^{-23} W/Hz

How to do 15 1/2 - 2 1/10 how to do it
lisov135 [29]

First, you need to make the fractions have the same denominator:

15  1/2        --->       15 + (1/2 x 5)  =   15  5/10

2   1/10       --->       2  1/10

Then you need to subtract them from each other:

  15   5/10                                        

<u>-    2   1/10</u>                   (or)                  15  5/10 - 2 1/10 =   13  4/10

   13   4/10

This gets the answer:   <u>13  4/10</u>
