Answer:

Density of the object is 8759.494 grams/L

Explanation:

As we know density of an object is mass of the object divided by its volume

Given

Volume of the object is equal to the change in volume of water with in the cylinder when the object was immersed in water.

Hence, volume of object is equal to

[tex]32.9 -25 = 7.9[/tex] mL

Mass of the object is [tex]69.2[/tex] grams

Density

[tex]= \frac{69.2}{7.9 *10^{-3}}\\= 8759.494[/tex] grams/L

Density of the object is 8759.494 grams/L

Answer:

1.) The possible genotypes are FF and Ff

The phenotype is full pod shape

2.) The possible genotypes are GG, Gg, and gg

The photypes are Green (for those whose genotype is GG and Gg) and yellow ( For those whose genotype is gg)

Explanation:

My hand writting isn't the best so I'll also type it.

1.) There are only 2 possible genotypes the offspring can have which are FF or Ff.

Because the dominant allele is F all the offspring from this cross will have a full pod shape phenotype.

2.) There are only 3 possible genotypes the offspring can have which are GG, Gg, and gg.

The majority of the offspring will have a green phenotype while the remainder will be yellow. G is the dominant allele so any offspring with the genotype GG or Gg will be green. While g is a recessive allele and only offspring who has a genotype of gg will be yellow.

*On my paper for question 2 for the phenotype explination I accidently wrote genotype instead of phenotype.

*Another note is that an offspring must have both recessive alleles in order to show the recessive traits. That is why gg is yellow and Gg is green.

Hope I helped

Answer:

1.44L

Explanation:

P1V1/T1=P2V2/T2

since the temperature didn’t change, stay at 20celsius, we can ignore T1 and T2.T1=T2

(1.00atm)(3.60L)=(2.50 atm)V2

V2=(1.00atm)(3.60L)/(2.50atm)

=1.44L

Answer: well I don’t have either picture but here goes anyway. It could be that the suns rotation matched up with the moon being 400 miles away from it and 400 times bigger it could be in image 1 the sun is only at a partial eclipse. With no images kinda had to wing it but I hope it helps :D

A lunar eclipse is an event that occurs when the sun, moon, and earth are aligned. It is happening in image 2 as Earth is obstructing the sun’s light.

In lunar eclipse Earth completely covers the surface of the moon which makes the surface look red and dark. It happens only when the Moon is opposite the sun in the sky.

It is not seen in the first image as the earth is incapable of totally blocking the sunlight and hence does not result in a lunar eclipse. In the second image, the Earth has covered the whole surface of the moon and hence is blocking the sunlight.

Therefore, a lunar eclipse is seen only in image 2.

Explanation:

what is red data list

Answer:

581 Joules.

Explanation:

Using the formula;

Q = m × c × ∆T

Where;

Q = amount of heat absorbed (J)

m = mass of substance (g)

c = specific heat capacity (J/g°C)

∆T = change in temperature (°C)

According to the information provided in this question;

Q = ?

mass of ice = 15.9g

initial temperature = -4°C

final temperature = 14°C

Hence, ∆T = 14 - (-4) = 14 + 4 = 18°C

specific heat capacity (c) of ice in J/g°C = 2.03 J/g°C

Using Q = m × c × ∆T

Q = 15.9 × 2.03 × 18

Q = 32 × 18

Q = 581 Joules.

The main need or want the wave technology shown meets to see objects surrounding more clearly.

It is a floating device that operates in the same direction as the waves. With the use of the technology, energy may be captured even from relatively small waves. The device that is moved by waves activates a hydraulic system that can power a generator. The tube segment contains all the generation equipment and systems.

Early mechanization (1770s to 1830s), steam power and railroads (1830s to 1880s), electrical and heavy engineering (1880s to 1930s), Fordist mass production (1930s to 1970s), and information and communication are the five waves that have so far slammed into our society (1970s to 2010s).

Wave energy, also known as wave power, is the energy that ocean surface waves carry and absorb. The energy is then put to use in a variety of productive ways.

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 0.24moles of propane gas would be present in 11 grams of the gas at standard conditions.

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.

Mathematically,

mole of substance =given mass of substance ÷ molar mass of substance

Molar mass of 1 mole of propane gas= 44.0956 g/mol

Given mass of propane gas=11 grams

Substituting all the given values in the above equation, we get

mole of substance =11 grams ÷44.0956 g/mol

mole of substance =0.24moles

Therefore, 0.24moles of propane gas would be present in 11 grams

of the gas at standard conditions.

Answer:

Q = 306 kJ

Explanation:

Given that,

Mass, m = 60 kg

Specific heat, c = 1020 J/kg°C

The temperature changes from 20°C to 25°C.

Let Q be the change in thermal energy. The formula for the heat released is given by :

[tex]Q=mc\Delta T[/tex]

Put all the values,

[tex]Q=60\times 1020\times (25-20)\\\\Q=306000\ J\\\\or\\\\Q=306\ kJ[/tex]

So, 306 kJ is the change in thermal energy.

Answer:

Option A

Explanation:

The total heat absorbed during the chemical reaction is the total heat released by the surrounding.

Net change of heat is equal to zero

Hence, the energy liberated from the air or the walls of the containers would be equal to the energy absorbed by the chemical reactions is equal to 100 Kj

Thus, option A is correct

Answer:

you didn't specify what the presentation was about. However, I can help you by showing you how to do this activity.

When making notes of the sources, you must show when these sources were built and what is their direct relationship with your research, in addition to highlighting the concepts and parts you will use in your presentation. It is also important that you show the connection between the sources, that is, how they come together to collaborate for your presentation. We must not forget that you must have different sources, that is, different media, such as websites, books, magazines, interviews, videos, among others.

After you have highlighted which parts of the sources you will use in the presentation, you should reread those parts and make topics about which point of those parts will be used in your presentation, that is, you must show the most revealing points, those to which you won't talk about.
