Answer:

Corn

Explanation:

Being a plant and having chlorophyll in its structures, corn is able to capture sunlight and converting it into chemical energy, through photosynthesis.

Photosynthesis is a process carried out by plants to produce their own food. The plant draws carbon dioxide from the air and energy from the sun. Through this process, the plant produces its own food consisting essentially of glucose.

Briefly, we can say that photosynthesis uses carbon dioxide, water and sunlight (in the form of heat) to produce organic compounds (glucose) and oxygen.

Imagine that you are playing a game of Clue in which Mrs. White is killed in the conservatory. You have a device in each room to

myrzilka [38]

Answer:

Mr. Plum killed Mrs. White.

Explanation:

1) Wavelengths for the different light colors (visible light) and related character:

Color Wavelength related character

Violet 380–450 nm ← Professr Plum

Blue 450–485 nm ← Mrs. Peacock

Cyan 485–500 nm

Green 500–565 nm ← Mr. Green

Yellow 565–590 nm ← Colonel Mustard

Orange 590–625 nm

Red 625–740 nm ← Miss Scarlet

2) At the time of the murder, the spectrometers recorded:

a) In the dining room: 520 nm.

520 nm is in the range 500 - 565 nm, which is the range for green color, so Mr. Green was in the dining room and is no more a suspect.

b) In the lounge and study: lower frequencies.

Since frequency and wavelength are inversely related, the wavelengths in the longe and study have to be of yellow and red colors, which are the only two with longer wavelengths from the option given.

Then, Mustard and Scarlet are not criminal.

c) In the library: the second shortest wavelength of the five recorded.

The second shortest wavelength, as per the table, is that of blue color. So, Mrs. Peacock is not the killer.

The only left option is violet, so Mr. Plum is the only who could be at the conservatory and he is the killer.

A solid is 5 cm tall, 3 am wide, and 2 cm thick. It has a mass of 135 g. What is the solid's density?

gizmo_the_mogwai [7]

Answer:

density of solid = 4.5 g/cm³

Explanation:

density = mass ÷ volume

• We know the mass of the object (135 g). We need to calculate the volume:

Volume = length × width × thickness

= 5 cm × 3 cm × 2 cm

= 30 cm³

• Now we can calculate the solid's density:

density = 135 g ÷ 30 cm³

= 4.5 g/cm³

Use dimensional analysis to convert 4.68 g of Boron to cubic centimeters of Boron. The density of Boron is 2.34 g/cm^3

harina [27]

Answer:

The cubic centimeter of boron is 2.

Explanation:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Given data:

mass of boron = 4.68 g

density of boron = 2.34 g/cm³

volume = ? (cm³)

Solution:

d = m/ v

v = m/d

v = 4.68 g/ 2.34 g /cm³

v = 2 cm³
