Answer: 9.05 s

     

<h2>Explanation: v = u +at</h2>

v = 3 m/s

u = 22 m/s

Deceleration = 2.1 m/s^2

∴ 3 = 22 - 2.1 ( t )

∴ t = 9 .05 s

What is the effective resistance of this dc circuit
Inessa05 [86]

You've managed somehow to post the mirror image of the circuit diagram, including the numbers and values of the resistors.  I'm curious to know how you did that.

The three resistors at the left end of the diagram are  3Ω ,  2Ω , and  1Ω  all in series.  They behave like a single resistor of  (3+2+1) = 6Ω .

That  6Ω  resistor is in parallel with the  2Ω  drawn vertically in the middle of the diagram.  That combination acts like a single resistor of  1.5Ω  in that position.

Finally, we have that  1.5Ω  resistor in series with  1Ω  and  4Ω  .  That series combination behaves like a single resistor of  <em>6.5Ω</em>  across the battery V.

What is the Scientific definition of friction?
seropon [69]
Friction<span> is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.
Hope this is of great help to you, and happy studying~!

A car traveling at 40 m/s starts to decelerate steadily. It comes to a complete stop in 5 seconds. What is its acceleration? m/s
SCORPION-xisa [38]
Acceleration =

           (change of speed)  /  (time for the change).

Change of speed = (speed at the end) - (speed at the beginning)

                          =      ( zero )  -  (40 m/s)

                           =        -40 m/s .

Acceleration =  (-40 m/s) / (5 seconds)

                   =    -8 m/s² .

Does heat rise or fall?? the last person that answered did it just for the points and gave me no real answer
nasty-shy [4]
Heat does not rise or fall because it is an energy being transferred. It is the hot air which rises because colder air is denser than hotter air.
