When are you most aware of your motion in a moving vehicle: when it is moving steadily in a straight line or when it is accelera

ting? If you were in a car that moved with absolutely constant velocity (no bumps at all), would you be aware of the motion?A) Accelerating. You would not be aware of the motion if you did not look outside the car.B) Accelerating. You would be aware of the motion because humans can sense speed.C) Moving steadily in a straight line. You would be aware of the motion because you can feel velocity even in a closed car.D) Moving steadily in a straight line. You would be aware of the motion because you can feel the speed.

Answer:

A) Accelerating. You would not be aware of the motion if you did not look outside the car

Explanation:

Since human cannot sense the motion (unless visually), but the inertia force caused due to the acceleration of the motion. So if you are in a car with constant velocity, there's no acceleration and no inertia force, you would not be able to sense the motion at all unless you look outside.

murzikaleks [220]

Answer:

T = 0.0088 m²/s

Explanation:

given,

initial piezometric elevation = 12.5 m

thickness of aquifer = 14 m

discharge = 28.24 L/s = 0.02824 m³/s

we know                              

k = \dfrac{qln(\dfrac{R_2}{R_1})}{2\pi D(H_2-H_1)}

k = \dfrac{0.02824 \times ln(\dfrac{75}{25})}{2\pi \times 14 (11.45-10.89)}                                                                        

k = 0.629 mm/sec

Transmissibilty

T = k × H                          

T = 0.629 × 14 × 10⁻³

T = 0.0088 m²/s

Design an experiment to test the rate at which temperature changes for two different masses (amounts) of water.
mrs_skeptik [129]

Answer:Experimental Question:  How does the amount of a substance affect the rate at which temperature changes?

It depends on the conductivity of the material. If the shift is extreme, the temperature near the heating / cooling source will be similar to the temperature of the heating / cooling source and it will take time for the remainder of the material to rise to temperature. It will depend on the conductivity of the material.

Hypothes is:  

Materials  List:

• digital stopwatch

• 250ml beaker

• rubber bung

• thermometer

• bunsen burner

• tripod

• gauze

• retort stand and clamp

• goggles

Safety Procedures *:

1. Adult supervision is required.  

2. Wear safety goggles, apron, and closed-toe shoes.  

3. Do not wear baggy sleeves or dangling jewelry. Tie long hair back.  

4. Use hot pads or oven mitts to handle hot objects.  

5. Do not reach over a hot burner.  

6. Do not leave the experiment unattended.  

7. Clean up spills immediately.  

8. Report any injuries to your Learning Coach or adult supervisor immediately

Experimental Procedures :

• Fill an empty beaker with exactly 150ml of water (check side-scale of beaker)

• Set up apparatus as shown above. Ensure the thermometer is about 2cm above the bottom of the beaker.

• Light the bunsen burner and put on a blue flame. Heat up the water.

• When the temperature on the thermometer has reached 90°C, immediately switch off the burner.

• Start the stopwatch and time for 5.0 minutes.

• Read the thermometer value at the 5.0 minute mark.

• Before repeating the experiment, check the level of water is still 150ml

Data Table:  

Start Temperature of Water (°C) Temperature after 5min (°C) Drop in Temperature

(°C) Average Rate of Cooling x 1000 (°C/s)

80 70 10 17

75 66 9 15

70 62 8 13

65 59 6 10

60 55 5 8

Analysis:  

Conclusions : There is a strong correlation between the average rate of cooling and the start temperature: the greater the start temperature, the  faster the average rate of cooling.
