Answer:
Explanation: It would go straight because objects in motion stay in motion and it would stay the same direction
Consider going around a horizontal turn to the right. If the coaster suddenly slipped off the track, It would go straight because objects in motion stay in motion and it would stay the same direction.
What is motion ?"Movement of any object from one position to another position with respect to the observer is called as Motion."
Motion is change of location or position of an object with respect to time. Change in motion is the result of an applied force. Motion is typically described in terms of velocity also seen as speed, acceleration, displacement, and time.

The gravity of Earth is attracting a person towards the center with 500N of gravitational force. The person is exerting a reactionary force on the Earth with how much force? Explain your thinking behind this.
Answer:
500n
Explanation:
Which of the following metals is most reactive?
A. aluminum
B. sodium
C. copper
D. calcium
Answer:
A. aluminum
Explanation:
Aluminium is soft, lightweight and ductile with excellent thermal and electrical conductivity. It is highly reactive, though the metal is protected by a surface layer of inert transparent oxide (Al2O3) that forms rapidly in air, providing excellent corrosion resistance.
If a bowler rolls the bowling ball down the alleyway with a force of 1,000N. The ball exerts a reaction force again the alleyway with approximately how much force? Explain your thinking behind this.
Answer:
1,000
Explanation:
because the ground won't stop the ball so it is always going to stay the same
What is an example of a reservoir?
1. Beach
2. Cloud
3. Desert
4. Lake

A reservoir (/ˈrɛzərvwɑːr/; from French réservoir [ʁezɛʁvwaʁ]; lit. 'storehouse') is, most commonly, an enlarged natural or artificial lake, pond, or impoundment created using a dam or lock to store water.
Please give brainiest if correct, would rlly appreciate it :D
Answer:
Lake
Explanation:
The meaning of reservoir is a large natural or artificial lake used as a source of water supply.

what energy transformation occur when propane gas is used to lift a hot air balloon?
A. Mechanical --> light --> chemical
B. Chemical ---> mechanical --> light
C. thermal --> chemical --> light
D. chemical --> thermal --> mechanical
Answer:
the answer is D. chemical, thermal, and mecanical
The energy transformation occur when propane gas is used to lift a hot air balloon is Chemical-> mechanical-> Light.
What is Propane gas role in hot air balloon?
Propane can be produced from the components of liquid which is recovered during natural gas processing. Also these components include ethane, methane, propane, and butane, as well as heavier hydrocarbons.
The molar mass of propane is C₃H₈ - (12x3) + (1x8)= 44 g/mol.The number of moles of propane present - 0.200 mol1 mol weighs - 44 gMass of propane present - 8.8 gThe energy conversion for the propane, that is, energy transformations that occur when propane gas is used to lift the balloon will be:
The chemical propane will be burned at first.All the process in the balloon will be checked and concluded as good mechanism without any leakage.When the propane gas was fired the balloon goes up and its gets lifted with thermal energy.The thermal energy give the Light.Thus, the process can be simplified as the Chemical energy converting to mechanical energy which later converted to thermal energy and to the Light energy.
Hence, Option B is the correct answer.

Objects that are denser than water will sink in water. Question 1 options: True False
For example, a very dense metal will sink to the bottom while something like wood will float on the surface. The wood is less dense compared to the water, which is why it floats. Density is the measure of how much stuff you can pack in a certain volume. The higher the density, the more stuff per volume. Think of it like packing a suitcase. If there's barely anything in there, then we can say its density is low. The more stuff crammed in the suitcase will increase the density (and therefore the weight), while keeping the volume the same.

true

In this image of Earth and the Moon from the Sim, what does the circle around Earth represent?
Answer: This is the orbit (of the moon around Earth).
An orbit is a circular/oval path that planets, moons, comets, etc follow with a "subject" in the middle. In this case, the circle is the orbit of the moon around Earth.
The circle around the earth represents the orbit.
What is an orbit?It is considered to be the regular, repeating path where one object should be in space that takes around the another one. The object in the orbit known as the satellite. It could be in natural way such as earth or moon. Also, it is the circular oval path where the planets, moons could follow the subject.
