Find the exact value. tan(−300∘)

Answers

Explanation:

tan(-300) = tan(-300+360) = tan (60)

here we added 360 degree. where by adding 360 +or- (n×360) to the any angle nothing will change as they called equivalent angles

equivalent angles is by adding +or- n×360 to any angle is equivalent to that angle so tan(-300) = tan(60) then we will calculate tan(60) on the calculator

You have 150 g of water (m). The specific heat of the water is 4.184 g/jC (c) . You heat the water and raise the temperature by 1 degree. How much heat did the water absorb?

Answers

Answer:

627.6J

Explanation:

q=mcΔT

where:

q = heat energy (J)

m = mass (g)

c = specific heat (g/j*C)

Δt = change in temperature (C/K)

q= (150)(4.184)(1) = 627.6

Which describes a property of water that allows plants to transfer it from their roots to their leaves?

Answers

Answer:

Explanation:

took the test

Water exhibits strong adhesion and cohesion, which allows capillary action to occur.

What property of water allows it to move through a plant?

The cohesive properties of water (hydrogen bonding between adjacent water molecules) allow the column of water to be 'pulled' up through the plant as water molecules are evaporating at the surfaces of leaf cells. This process has been termed the Cohesion Theory of Sap Ascent in plants.

What are adhesion and cohesion?

Cohesion and adhesion are two water properties that describe how water molecules interact with each other. and how water molecules interact with other things like leaves or even you. Cohesion means that water likes to stick to itself and adhesion means that water likes to stick to other things.

Explanation:

1 Which atom contains exactly 16 neutrons?

Neutrons = Mass Number - Proton

A -33;

Neutrons = 33 - 16 = 17

B P-31

Neutrons = 31 - 15 = 16 Correct option

C O-16

Neutrons = 16 - 8  = 8

D Cl – 35

Neutrons = 35 - 17 = 18

2. In a mass spectrometer, the heaviest particles are least deflected and that with the least mass are deflected the most. The correct option is B.

3. 1 mol of C = 12 grams;

3 mol = x

x = 3 * 12 = 36 grams Correct option is C

4. 1 mol = 27g of Al;

x mol = 65g

x = 65 / 27 = 2.4 moles. Correct option is A.

5. There are 6.022 x 10^23 atoms in 23 grams of sodium;

x atoms in 4.5g

What is the specific heat of a substance that absorbs 228 joules of heat when a sample of 706 g of the substance increases in tempature from 26.0 c to 88.8 c

Answers

Answer:

[tex]c=5.14\ J/kg ^{\circ} C[/tex]

Explanation:

Given that,

Heat absorbed by a sample, Q = 228 J

Mass of a sample, m = 706 g = 0.706 kg

Initial temperature is 26 °C and final temperature is 88.8°C

We need to find the heat absorbed by the sample. The heat absorbed by an object is given by :

[tex]Q=mc\Delta T\\\\\text{Where c is specific heat of sample}\\\\c=\dfrac{Q}{m\Delta T}\\\\c=\dfrac{228\ J}{0.706\ kg(88.8-26)^{\circ} C}\\\\c=5.14\ J/kg ^{\circ} C[/tex]

So, the specific heat of the sample is [tex]5.14\ J/kg ^{\circ} C[/tex].

Carbon-rich exoplanets may be made of diamonds

Date: September 11, 2020

Source: Arizona State University

Summary: Astronomers have determined that some carbon-rich exoplanets, given the right circumstances, could be made of diamonds and silica.

Explanation:

As missions like NASA's Hubble Space Telescope, TESS and Kepler continue to provide insights into the properties of exoplanets (planets around other stars), scientists are increasingly able to piece together what these planets look like, what they are made of, and if they could be habitable or even inhabited.

In a new study published recently in The Planetary Science Journal, a team of researchers from Arizona State University (ASU) and the University of Chicago have determined that some carbon-rich exoplanets, given the right circumstances, could be made of diamonds and silica.

"These exoplanets are unlike anything in our solar system," says lead author Harrison Allen-Sutter of ASU's School of Earth and Space Exploration.

Diamond exoplanet formation

When stars and planets are formed, they do so from the same cloud of gas, so their bulk compositions are similar. A star with a lower carbon to oxygen ratio will have planets like Earth, comprised of silicates and oxides with a very small diamond content (Earth's diamond content is about 0.001%).

But exoplanets around stars with a higher carbon to oxygen ratio than our sun are more likely to be carbon-rich. Allen-Sutter and co-authors Emily Garhart, Kurt Leinenweber and Dan Shim of ASU, with Vitali Prakapenka and Eran Greenberg of the University of Chicago, hypothesized that these carbon-rich exoplanets could convert to diamond and silicate, if water (which is abundant in the universe) were present, creating a diamond-rich composition.

Diamond-anvils and X-rays

To test this hypothesis, the research team needed to mimic the interior of carbide exoplanets using high heat and high pressure. To do so, they used high pressure diamond-anvil cells at co-author Shim's Lab for Earth and Planetary Materials.

First, they immersed silicon carbide in water and compressed the sample between diamonds to a very high pressure. Then, to monitor the reaction between silicon carbide and water, they conducted laser heating at the Argonne National Laboratory in Illinois, taking X-ray measurements while the laser heated the sample at high pressures.

As they predicted, with high heat and pressure, the silicon carbide reacted with water and turned into diamonds and silica.

Habitability and inhabitability

So far, we have not found life on other planets, but the search continues. Planetary scientists and astrobiologists are using sophisticated instruments in space and on Earth to find planets with the right properties and the right location around their stars where life could exist.

For carbon-rich planets that are the focus of this study, however, they likely do not have the properties needed for life.

While Earth is geologically active (an indicator habitability), the results of this study show that carbon-rich planets are too hard to be geologically active and this lack of geologic activity may make atmospheric composition uninhabitable. Atmospheres are critical for life as it provides us with air to breathe, protection from the harsh environment of space, and even pressure to allow for liquid water.

"Regardless of habitability, this is one additional step in helping us understand and characterize our ever- increasing and improving observations of exoplanets," says Allen-Sutter. "The more we learn, the better we'll be able to interpret new data from upcoming future missions like the James Webb Space Telescope and the Nancy Grace Roman Space Telescope to understand the worlds beyond on our own solar system."

A box has dimensions of 2.0 cm time 4.0 cm times 8.0 cm, what is the volume of the box in milliliters?

Answers

Answer:

64 mL.

Explanation:

From the question given above, the dimension of box is:

Dimension = 2 cm × 4 cm × 8 cm

Thus, the volume of the box is:

Volume = 2 cm × 4 cm × 8 cm

Volume = 64 cm³

Finally, we shall convert 64 cm³ to mL. This can be obtained as follow:

Recall:

1 cm³ = 1 mL

Therefore,

64 cm³ = 64 cm³ × 1 mL / 1 cm³

64 cm³ = 64 mL

Therefore, the volume of the box in millilitres (mL) is 64 mL.

Answers

Answer:

Volume = 30cm³

Explanation:

A block is a geometrical figure and its volume, -look at the figure-, follows the equation:

Volume = Width*Length*Height

As the measurements of the block are 5.00cm, 3.00cm and 2.00cm, the volume is:

Volume = 5.00cm*2.00cm*3.00cm

Volume = 30cm³

Imagine you need to explain to a friend how to convert a value on a food label to one that is measured in grams. Assume the package of food has a mass of 1.0 pounds. write an explanation for how to use dimensional analysis to convert this value to one expressed in grams.

Answers

Answer:

453.592 grams

Explanation:

Given

Mass = 1 lb

Required.

Convert to grams using dimensional analysis

Represent 1 lb with x g

In unit conversion, we have that.

1 lb = 453.592 g

So:

Getting the equivalent of lb in g, we have:

x g = 1 lb * (453.592 g/ 1 lb)

x g = 1 * 453.592 g

x g = 453.592 grams

Hence:

The equivalent of 1 lb in grams is 453.592 grams
