What are uses of colours in art design?

Water quality vs fish population

Dissolved oxygen 0,2,4,6,8,10,12,14,16,18

Number of Fish observed: o,1,3,10,12,13,15,10,12,13

1. Based on the information above, what patterns do ouobserve?

2. Develop a hypothesis relating to the amount of dissolvedoxygen measured in the water sample and the number of fish observedin the body of water.

3. What would your experiment approach be to testthishypothesis?

4. What are the independent and dependent variables?

5. What would be our control?

6. What type of graph would be appropriate for this data set?why?

7. Genrate a line graph of the data from the table above andpaste it below

8. Interpret the data from the graph made in question 7; what isthe relationship dissolved oxxygen concentration and the number offish and why.

Hi, Please help with terminal velocity equations;

The equation for terminal velocity is v= √(2mg/ρAC)

Wherein:

v = terminal velocity (m/s)

m = mass (kg)

g = gravity (9.8 m/s²)

r = density (for air at sea level we will use 1.5 kg/m³)

A = cross-sectional area of the object (for our scenario, we will use a cube with A=1.5 m²)

C = drag co-efficient (we will use 1.05 for the drag co-efficient of a cube)

Your job:

.Calculate the terminal velocity of five cubes. You may need to convert!

Cube #1 has a mass of 2000 g.

Cube #2 has a mass of 4000 g.

Cube #3 has a mass of 5 kg.

Cube #4 has a mass of 6 kg.

Cube #5 has a mass of 0.479652 slugs.

Your answer for “v” should have four decimal places.

1. *****Please show step by step Instruction on how solve the equation for terminal velocity*******

2. *****Please show the equation used in excel on how to determine Terminal Velocity*************

Thank you, Donna

solve for mass at t=5

Current experiments in atomic trapping and cooling can createlow-density gases of rubidium and other atoms with temperatures inthe nanokelvin (1.00 10-9 K) range. These atoms are trapped andcooled using magnetic fields and lasers in ultrahigh vacuumchambers. One method that is used to measure the temperature of atrapped gas is to turn the trap off and measure the time it takesfor molecules of the gas to fall a given distance. Consider a gasof rubidium atoms at a temperature of 97 nK. Calculate how long itwould take an atom traveling at the rms speed of the gas to fall adistance of 11.0 cm if it were initially moving directly downwardand if it were initially moving directly upward. Assume that theatom doesn't collide with any others along its trajectory.

3. Why did Cavendish use a telescope to observe the deflection of the rod?

He needed a way to magnify the rod.

He needed a way to make the rod look smaller.

He needed a way to observe the rod from a distance.

He needed a way to move the rod.

4. Magnetism was another potential source of error. The source of the magnetic field Cavendish
was concerned about was-

the enclosure around his apparatus.

Earth.

the metal balls and rods.

The air currents.

5. What did Cavendish discover with respect to the temperature of the balls in his experiment?

It had no effect.

It could be a source of error.

It was better to use balls at many different temperatures.

It was better to freeze balls before using them.

6. Experiments exploring sources of error-

were performed only by scientists working before 2000.

have been performed only by contemporary scientists.

are considered unimportant with modern instruments.

are important for most scientific studies.
