carry astronauts and equipment
capture panoramic surface images

Answer:

protons and neutrons

Explanation:

Answer:

Atoms are composed of particles called protons, electrons and neutrons. ... A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. Protons and neutrons are both composed of other particles called quarks and gluons.

Particles can be atoms, molecules or ions. The term molecule is often used incorrectly to refer to any type of chemical compound. A molecule is a neutral particle made of two or more atoms bonded together. Take care with your own language, especially when referring to compounds formed during chemical reactions.

Answer:

Lightbulb: electrical energy to light energy

Alarm Clock: electrical energy to sound energy

Rollercoaster: electrical energy to mechanical energy

Riding a Bike: chemical energy to mechanical energy

Explanation:

Light bulbs, alarm clocks, and roller coasters require electrical energy to work. This energy then changes into the subsequent types. Light bulbs primarily emit that energy in the form of light, alarm clocks change that energy into sound, and roller coasters begin to move (mechanical). People power bikes, and the energy in our body is stored as chemical energy. So, when we rides bikes, that energy gets turned into moving (mechanical) energy.

Addition of NaOH will cause the equilibrium position to move to the left because of the removal of the hydrogen ions.

When changes in temperature, pressure or concentration is imposed on a reaction system in equilibrium, the system will readjust itself in order to annul the change.

This change occur when the equilibrium position is moved to the left or right. For the reaction, CrO4^2-+ 2H^+ ⇄ Cr2O7^2- + H2O, addition of NaOH will cause the equilibrium position to move to the left because of the removal of the hydrogen ions.

Answer:

Aluminum

Explanation:

Ferromagnetic Metals

Ferromagnetic metals and alloys are the only magnetic metals. Out of all of the elements on the periodic table, there are only 3 metals that are attracted to magnets: iron, nickel, cobalt.

Aluminum

Aluminum is a nonferrous metal (meaning not including iron or steel) that does not include any ferromagnetic metals. Additionally, aluminum itself is not magnetic, so there is no attraction between aluminum and a magnet.

Answer: 434 Kelvin

Explanation:

Assuming pressure is constant, the formula: V / T = V / T can be used.

However, all temperatures must first be converted to Kelvin by adding 273 to them:

(35 + 273) = 308K

Now, plug in: 606 / 308 = 854 / T → 1.98753T = 854 → 434 K :)

The new volume of a gas at STP that occupies 16L of space is 27.43L.

The volume of a given gas can be calculated using the following expression:

P1V1/T1 = P2V2/T2

Where;

1 × 16/273 = 2.6 × V2/468

16/273 = 2.6V2/468

0.0586 × 468 = 2.6V2

V2 = 27.43

Therefore, the new volume of a gas at STP that occupies 16L of space is 27.43L.

Answer:

Newton's Second Law states that an object's acceleration depends on the net force upon the object, as well as the object's mass.

So, a real world example of this would be pushing a vehicle out of a ditch. If your vehicle is a motorcycle, with a relatively small mass, then you don't need to apply much force on it, as compared to if the vehicle were a pickup truck, with a large mass, which would require much more force applied to move it out of the ditch.

Answer: Nitric acid + Hydrogen disulfide

Explanation: To balance HNO3 + H2S = NO + S + H2O you'll need to be sure to count all of atoms on each side of the chemical equation.

Once you know how many of each type of atom you can only change the coefficients (the numbers in front of atoms or compounds) to balance the equation for Nitric acid + Hydrogen disulfide .

Important tips for balancing chemical equations:

Only change the numbers in front of compounds (the coefficients).

Never change the numbers after atoms (the subscripts).

The number of each atom on both sides of the equation must be the same for the equation to be balanced.
