All of them have something that's not like the others.

-- Rubber is the only one on the list that has two repeated letters.

-- Plastic is the only one on the list thagt has no repeated letters.

-- Plastic is the only one on the list that has no 'r' in its name.

-- Copper is the only one on the list that is an element, not a compound.

-- Copper is the only good electrical conductor on the list.

-- Plastic is the only one on the list with more than six letters in its name.

-- Rubber is the only one on the list with no 'p' in its name.

-- Plastic is the only one on the list that doesn't end in "-er".

Testing Plant Growth with Fertilizer
kykrilka [37]

b) by the end of the fifth day, group b will be more than one cm taller than group a. eliminate

Explanation:

The correct prediction based on the data shown is that by the end of the fifth day, group B plants will be more than 1cm taller than group A plants.

let us examine the table closely;

Day Group A (Water Only) Plant Height (cm) Group B (Water and Fertilizer)

1                                         2.0                                                 2.0

2                                         2.2                                                 2.3

3                                         2.3                                                 2.8

4                                        2.5                                                  3.2

5                                        2.6                                                  3.8

We can see that by the end of the fifth day, the height differences between the two plants, 3.8 - 2.6 = 1.2cm, this is greater than 1cm. This claim from the experiment is very correct.

Other predictions are false.

Two identical wooden barrels are fitted with long pipes extending out their tops. The pipe on the first barrel is 1 foot in diam
ELEN [110]

Answer:

To burst the second barrel, the height of water should also be equal to 20 feet

Explanation:

Diameter of the pipe on the first barrel = 1 ft

Diameter of the pipe on the second barrel = 1/2 inch

The pressure of water in the pipes needed to burst the barrel, P = h \rho g

To burst the barrel having the larger pipe, water was filled to a height of 20 ft

Note that the pressure of water in the pipes as given by the equation above does not depend on the diameters of the pipe. It only depends on the height, density and acceleration due to gravity. Since the density of water and the acceleration due to gravity are constant, for the second pipe to also attain the same pressure as the first pipe needed to burst the barrel, the height of water in the two pipes must be equal

An echo is heard from a cliff 3.71 s after a rifle is fired. How many feet away is the cliff
LenKa [72]

The cliff is 2042 ft away.

We know that the speed of sound in air is directly proportional to the absolute temperature.

First convert the Fahrenheit temperature to Celsius;

 °C = 5/9(44.5 - 32)

°C = 6.9 °C

Applying the formula;

V1/V2 = √T1/T2

Where; V1 = velocity of sound in air at  0°C

V2 = Velocity of sound in air at 6.9 °C

1087/V2 = √273/279.9

V2= 1101 ft/s

Given that; V = 2s/t

Where s is the distance of the cliff

t is the time taken

1101 ft/s = 2s/3.71 s

s = 1101 ft/s × 3.71 s/2

s = 2042 ft
