Given:

v \frac{x}{y} \frac {t} {0}  = 13  \frac{m} {s}

v  \frac{0} {g} = 0  \frac{m} s}

SOLUTION:

(a) 

v \frac{s} {t} = ? for   v \frac{s} {0} = +18  \frac{m} {s}

v \frac {s} {t} = v  \frac {s} {0} + v  \frac {0} {T} = +18  \frac {m} {s} + (-13  \frac {m} {s} )

v  \frac {s} {t} = +5  \frac {m} {s}

(b) 

v  \frac {s} {t} = ? for  \frac {s} {0} = -3.0  \frac {m} {s}

v  \frac {s} {t} = v  \frac {s} {0} + v  \frac {0} {t} = -3.0  \frac {m} {s} + (-13  \frac {m} {s} ) = -16  \frac {m} {s}

(c)

v \frac {s} {t} = ? for \frac {s} {0} = 0 \frac {m} {s}

v \frac {s} {t} = v \frac {s} {0} + v \frac {0} {t} = 0 \frac {m} {s} + (-13 \frac {m} {s} ) = -13 \frac {m} {s}

Why doesn't electric current flow through rubber?
PolarNik [594]
Rubber is a insulator so current cannot pass through it where as metal is a conductor which allows current to pass through it

The position of a ball rolling in a straight line is given by x=2−3.6t+4.4t2, where x is in meters and t in seconds.
kobusy [5.1K]
I'm assuming the question is time it will take for ball to reach ground, if it is then set equation to zero then use the quadratic formula, the possible t value is your answer then

PLEASE HELP ME,, I WOULD BE SO HAPPY
Juliette [100K]

Answer:

Energy is force times distance. For your problem, no matter how long you push, the wall still goes nowhere, so there is no obvious energy transfer. so in conclusion, you actually didn't do anything :(

A girl weighing 50 kgf wears sandals of pencil heel of area of cross section 1 cm^2, stands on the floor.An elephant weighing 20
Klio2033 [76]

Answer:

\boxed{{\boxed{\blue{ 12.5}}}}

Explanation:

Given, for girl : Weight or force;

\rm \: F_1 = 50 \: kgf

Area of both heels;

\rm \: A_1 =  \; 2 ×1 \;  cm^2 = 2  \: cm^2

\rm \: Pressure \:  P_1  =  \cfrac{F_1}{ A_1 }  =  \dfrac{50 \: kgf}{2 \: cm {}^{2} }  = 25 \: kgf \: cm {}^{ - 1}

For elephant, Weight = Force \rm F_2 = 2000 kg•f

Area of 4 feet;

\rm \: A_2  = \; 4 \times 250 \;  cm^2 = 1000 \:  cm^2

\rm \: Pressure \:  P_2 = {F_2}/{A_2} \;  = \cfrac{2 \cancel{0 00 }\:  kgf}{1 \cancel{000} \: cm^2} =  2 \: kgf \: { \:cm}^{- 1}

Now;

\rm  = \dfrac{Pressure \:  Exerted  \: by  \: the \:  Girl}{Pressure  \: exerted  \: by \:  the  \: elephant}

=  \rm \: P_1/P_2

\implies    \rm\cfrac{25 \: kgf \: \: cm {}^{ - 2} }{2 \: kgf \: cm {}^{ - 2} } =  \rm\cfrac{25 \:  \cancel{kgf \: \: cm {}^{ - 2}} }{2 \: \cancel{ kgf \: cm {}^{ - 2}} } = \boxed{12.5}

Thus, the girl's pointed heel sandals exert 12.5 times more pressure P than the pressure P exerted by the elephant.

I aspire this helps!

Which best describes the relationship between the direction of energy and wave motion in a transverse wave?
sammy [17]
I think the correct answer from the choices listed above is the second option. The relationship between the direction of energy and wave motion in a transverse wave would be the <span>energy direction is perpendicular to the motion of the wave. Hope this answers the question. Have a nice day.</span>
