An atomic physicist determines that an atom is composed of 8 positively charged particles and has a mass of 15 amu. Which is the best conclusion that can be drawn?

Answers

Answer 1

Answer: Assuming this is a neutral atom, protons = electrons = atomic number
Since there are 8 positively charged particles or protons, there are also 8 electrons and that element's atomic number is 8. Neutrons is atomic mass minus atomic number which is 7 neutrons in this case.This element is therefore oxygen.

Answer 2

Answer:

Answer:

A.) The atom has 7 neutrons and 8 protons.

Blue light and yellow light combine to produce white light becausea. they absorb each other s wavelengths.
b. blue, yellow, and white are primary colors.
c. they are complementary colors of light.
d. they are both primary colors of light.

Answers

Answer: The correct answer is c.

Explanation: According the RGB color model, the light of the two complementary colors will combine to form a white light. This happens because the complementary colors combine at full intensity.

Complementary colors according to RBG color model is:

Red - Cyan
Green - Magenta
Blue - Yellow

From the above information, we conclude that blue light and yellow light are complementary colors of light and hence, the combination of two will produce white light.

Blue and yellow light combine to produce white light because they are complementary colors of lights.
When you say complementary colors, it refers to a combination of 2 colors that when mixed, they fade out their color. That's why when blue light and yellow light are combined they produces white light.

What environmental factors affect kinetic energy and diffusion?

Answers

There are several environmental factors that affect the kinetic energy and diffusion. The environmental factors are temperature, molecular size, and pressure, nature of the material and the concentration of the material. All the mentioned factors directly impact the kinetic energy and diffusion of a material or compound or fluid. Temperature can generally increase the kinetic energy of molecules within a compound or a substance. Increase or decrease of temperature changes the shape and nature of the material concerned. So these natural factors have a big influence on the kinetic energy and diffusion.

Answers
Temparature
Humidity (Amount of molecules in the air)

Explanation
Examples of environmental factors are, temperature, wind, pressure, humidity etc. Kinetic energy is the energy possessed by a body in motion.
This motion can be affected by factors such as rain and humidity since the make the medium more dense. It require more energy to move in a denser medium.
Diffusion is the movement of molecules from a region of high concentration to a region of low concentration. When temperatures are high the molecules get more energy and move more faster increasing the rate of diffusion.

If a group of workers can apply a force of 1000 newtons to move a crate 20.0 meters on a frictionless ramp: How high up a ramp will the crate travel?

Answers

That's going to depend on the mass of the crate. They'll be able to push a crate full of pingpong balls really high, but they may not be able to even budge the crate at all if it's full of bricks.

Hi there!

We know that:

Potential energy = mgh, where:

m = mass

g = acceleration due to gravity

h = height

We know that ΔPE = mgΔh = 1.47 kJ, so:

1.47kJ = mgΔh

Remember to convert kJ to J for simplicity: (1 kJ = 1000J)

1470J = mgΔh

Rearrange to solve for Δh:

1470/mg = Δh

1470/(60 · 9.8) = 2.5m

What is the bond between Hydrogen and Chlorine?

Answers

polar covalent bond
Hydrogen chloride is a diatomic molecule, consisting of a hydrogen atom H and a chlorine atom Cl connected by a polar covalent bond. The chlorine atom is much more electronegative than the hydrogen atom, which makes this bond polar.

covalent bond
chlorine and hydrogen atoms form a single covalent bond. in hydrogen chloride gas because the electrons are shared, not transferred from one atom to another. when it is dissolved in water to become hydrochloric acid.
