Answer:
Motion is defined as a change of position. How we perceive motion depends on our frame of reference. Frame of reference refers to something that is not moving with respect to an observer that can be used to detect motion.
Explanation:
In which biome would you most likely find plants that grow far apart from one another, with narrow leaves and shallow roots? Why do these plants have these adaptions?
Please help!?
Answer: Answer. A plant with narrow leaves and shallow roots would probably be found in the desert, where there is not a lot of water.
Explanation:
Answer:
A plant with narrow leaves and shallow roots would probably be found in the desert, where there is not a lot of water. Narrow leaves help prevent water loss.

How do you think heat moves through Earth's atmosphere?
Answer:
Conduction, radiation and convection all play a role in moving heat between Earth's surface and the atmosphere. Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface. Conduction directly affects air temperature only a few centimeters into the atmosphere.

Energy levels are arranged in increasing order of magnitude in accordance with the Bohr model.
The correct sequence of answers is as follows;
1) two in the first energy level, six in the second energy level
2) The electron has a negative charge and is found outside of the nucleus.
3) Subtract the atomic number from the mass number.
4) the number of protons
An atom contains a nucleus and electrons arranged in energy levels outside the nucleus. Each energy level is filled with electrons.
The first energy level contains only two electrons, subsequent energy levels contain a maximum of eight electrons.
The proton is positively charged, the neutron has no charge and the electron is negatively charged. The proton and neutron are found inside the nucleus while the electrons are negatively charged and found outside the nucleus.
The mass number is the sum of the number of protons and neutrons. hence the number of neutrons is the difference between the mass number and the number of protons.
The number of protons in an atom is its atomic number.

2. Sketch an example where an object appears to be moving from one reference frame but stationary from another reference frame
To solve this we must be knowing each and every concept related to motion. Therefore, earth revolving around sun is an example where an object appears to be moving from one reference frame but stationary from another reference frame
What is motion?Motion is the phenomena in physics when an object shifts positions over time. The variables of distance, speed, displacement, acceleration, velocity, and time are used to compute or characterize motion.
Because the streets are the ball's frame of reference when rolling down the street, rather than whatever might be on the other side of the road or the Earth, you can know the ball is moving. These are all just frames of reference. All motion data will be contrasted with a frame of reference. Earth revolving around sun is an example where an object appears to be moving from one reference frame but stationary from another reference frame
