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.
The major process would be glacial flow
The deep the probe goes, the lower the temperature becomes. Therefore, the probe will record temperature lower than 3°C. The figure attached shows the relationship between temperature and depth of water.
2 m/s² is the acceleration.
<u>Explanation:</u>
Acceleration is defined as the rate of change in velocity with respect to time.
Here the initial velocity, u = 4 m/s
the final velocity , v = 12 m/s
time = 4 seconds
Acceleration =
Plug in the values, we will get,
Acceleration =
= = 2 m/s²
(1) The difference in pressure between the ends of the pipe is 611 kPa.
(2) The Reynold's number for this torpedo is 1.2 x 10⁷.
(3) The flow of water around the torpedo is turbulent.
<h3>Difference in pressure between the ends of the pipe</h3>
The difference in pressure is calculated by applying Poiseuille formula.
where;
- Q is flow rate
- r is radius of the pipe
- L is length of the pipe
- η is viscosity
- ΔP is change in pressure
<h3>Reynold's number for the torpedo</h3>
<h3>Laminar or turbulent flow </h3>
- A flow is considered laminar if the Reynolds number is up to 2300.
- A flow is considered turbulent if the Reynolds number is greater than 3500.
The calculated Reynold's number (1.2 x 10⁷) is greater than 3500. Thus, the flow is turbulent.
