Air pressure decreases with altitude
hope that helps you!
Answer: The correct answer is "the same magnitude of force, 60 N should be applied".
Explanation:
Balanced forces: These forces are balanced when the forces are acting equal in magnitude but opposite in direction. The balanced forces will not cause any change in the speed of the object.
Unbalanced forces: These forces are unbalanced when the forces acting on the object are not equal in magnitude. It will cause the change in the speed of the body.
In the given problem, Jennifer stands on one side of a filing cabinet and pushes with a force of 60 N. If Nathan wants to help Jennifer demonstrate balanced forces, then he should apply the same magnitude of force of 60 N.
Batteries often convert chemical energy directly to electrical energy.
From the experiment, the constructed conclusion was that;
- The Two different gases with different properties are made from adding energy from a battery to water.
- The particles that make up these different gases is different from each other. They are different than the ones that were made from heating water.
- The matter that is composed of substances have to originate from matter that made up some of the original water particles.
When energy from a battery is added to
water, two streams of gas bubbles is said to be produced. Then a lit match is put into trapped gas from these two sources, one pops
and the other glows brighter.
The study was to test the flammability of gases produced by providing energy to water with electricity.

Answer:
average and instant
Explanation:
The average speed is the ratio of the <u>total path traveled and the time it took to travel that path</u>, that is why the first space must be average speed, this because it takes into account the total amount of distance, and the total amount of time.
Instant speed, is the speed an objet (in this case a car) has in <u>a particular moment in time</u>, for this speed it doesn't matter the distance or the time that the car has traveled, it only matters the speed in that moment, that is what the speedometer measures, thus the second blank space must be instant speed.
Answer:
hydrogen bond
Explanation:
Water has atom of oxygen and 2 atoms of hydrogen. The bond is formed between oxygen of one molecule and hydrogen of another molecule. This bond is called hydrogen bond.
