R= (rou * L) / area

where R is the wire resistance

rou: resistivity of the wire material

L : wire length

A : cross section area of wire

by sub.

0.757= (rou*25)/ 3.5*10^-6

25*rou = 2.6495*10^-6

rou= 1.0598*10^-7 ohm.m

**Answer;**

-A vent stack

**Explanation;**

**-A vent stack** is best described by, the vertical, upper portion above the top-most fixture through which gases and odors escape the sanitary drainage system, carrying no liquids or solids.

-The vent stack usually runs parallel with the soil/waste stack and may either extend up through the roof or connect to a stack vent. While a stack vent is the uppermost portion of a soil/waste stack that continues the pipe from above the highest connected fixture out the roof.

You already have the speed, now you need the time.

I will use the formula for speed which is S=D/T.

S=Speed D=Distance T=Time.

So here we have, 18m/s = 52m/T

we do 18 divided by 52 which would be .3461.

.3461 seconds is how long it took the stone to reach the water.

Answer:

The cart moved away from the starting point between 8 s and 10 s.

Explanation:

Given that :

Which of these does NOT describe the cart’s motion on this graph?

The cart was at rest between 5 s and 7 s : From the distance of golf cart Vs time graph ; the car was at rest between 5s and 7s as the graph was flat with that time interval, meaning there was no change in distance.

The cart moved toward the starting point between 7 s and 12 s. : The graph depicts a negative slope at this time interval as the distance from starting point fell from about 26 m to 10 m

The cart moved away from the starting point between 8 s and 10 s. : At this time interval, the cart moved towards the starting not and not away. This could be seen in the decrease in Distance from starting point between the tune interval.

The cart moved away from the starting point between 2 s and 5 s. - - > The cart moved away from the starting point, with the positive slope signifying an increase in distance.

Therefore, The cart moved away from the starting point between 8 s and 10 s does not describe the motion of the cart on the graph.
