The ________ the handle of a wrench, the _________ the mechanical advantage.
longer, greater
shorter, greater
shorter, less
shorter, less
Answer:
longer, greater;
Explanation:
This is more of a physics question. Refer to any notes you might have on simple machines. In short though, a wrench with a longer handle requires less force to be used than a wrench with a short handle. As a result it has more mechanical advantage.
The answer "shorter, less " could also be correct but it's listed twice so I wouldn't pick it.
Answer:
long,great
Explanation:

TRUE or FALSE: Any measurement that has been cubed is volume.
Answer:
True
Explanation:
Volume is measured in "cubic" units. The volume of a figure is the number of cubes required to fill it completely, like blocks in a box. Volume of a cube = side times side times side. Since each side of a square is the same, it can simply be the length of one side cubed.
find the density of a brick that has a mass of 57 g and a volume of 12 ml
Answer:

Explanation:
density = mass / volume
57 / 12 = 4.75
from here you can leave it as is or round up.

Which substance is a heterogeneous mixture? WILL LIKE AND THANK WHOEVER IS CORRECT :)
Suspension
Solution
Compound
Colloid
Answer:
Suspension!
Explanation:
A suspension is a heterogeneous mixture in which the solute particles do not dissolve, but get suspended throughout the bulk of the solvent, left floating around freely in the medium. The other answers are homogeneous, not heterogenous.
Have a fantastic day!

Explanation:
Choose your favorite super hero that gained their powers from radiation. What
type of radiation gave them their powers? Choose a wavelength that falls inside
that spectrum. Calculate energy (SHOW WORK).
Answer:
Copy and paste "Electromagnetic waves are categorized according to their frequency f or, equivalently, according to their wavelength λ = c/f. Visible light has a wavelength range from ~400 nm to ~700 nm. Violet light has a wavelength of ~400 nm, and a frequency of ~7.5*1014 Hz. Red light has a wavelength of ~700 nm, and a frequency of ~4.3*1014 Hz." into google, and the correct website pops up as the first result.
Explanation:
I tried to link the website that I use to convert wavelengths and frequencies into types of light, but it deleted my answer, so I guess we're doing it this way. As for converting the wavelength to energy, the same principles apply as before:
Frequency: ν Wavelength: λ Energy: E Speed of light: C (3.00e8) Planck's Constant: h (6.626e-34)
ν -> λ λ = C/ν
λ -> ν ν = C/λ
For either of these equations, wavelength must be converted to meters or nanometers, depending on the equation.
For ν -> λ, after doing the equation, convert the wavelength into nanometers by dividing by 1e-9.
For converting λ -> ν, convert the wavelength into meters by multiplying by 1e-9.
For energy: E = hν = hc/λ

Chloroform has a density of 1.5 g/ml. What the mass of 10.0 ml of Chloroform?
Answer:
The answer is 15 g
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volumeFrom the question
density of Chloroform = 1.5 g/ml
volume = 10 mL
We have
mass = 1.5 × 10
We have the final answer as
15 gHope this helps you
what did ruthorford discover that thomson did not understand
Answer: Atoms aren't entirely empty space
Explanation:
Rutherford did his scatter experiment to disprove Thomson's Plum Pudding Model. Rutherford shot helium nuclei at a sheet of gold and expected the particles to all go straight through to a sensor. The reason he expected this was because Thomson said that atoms are mostly made of empty space. Not all the particles went through the gold sheet, a lot of them actually reflected back to him. This meant that atoms aren't entirely empty space and something had to deflect the helium nuclei

Does beryllium (Be) or Sodium (Na) have the same electron arrangement as Magnesium (Mg)? Why?
Answer:
Na has the most similar configuration.
Explanation:
Na electron configuration: 1s²2s²2p⁶3s¹ or [Ne] 3s₁
Mg electron configuration: 1s²2s²2p⁶3s² or [Ne] 3s²
Be electron configuration: 1s²2s² or [He] 2s²
This is because Na and Mg are right next to each other in the same period (horizontal).
Answer:
Na has the most similar configuration. Na electron configuration: 1s²2s²2p⁶3s¹ or [Ne] 3s₁. Mg electron configuration: 1s²2s²2p⁶3s² or [Ne] 3s². Be electron configuration: 1s²2s² or [He] 2s². Na and Mg are right next to each other in the same period

If you are given 40 grams of a dye that has a molar mass of 200 g/mole and then place it in 2
liters of water, what is the molarity of the resulting solution?
A2M
B 0.1 M
C 1M
D2M
Answer:
B
Explanation:
to find how many moles we have you need to use the molarity equation which for this is
40g * (1mole/200g) = .2 moles
Given we know that we have .2 moles
then all you have to do is divide amount of moles by amount of liters to find the molarity
for this problem it is
.2mol/2L which is .1 M
