1- C ( this is an assumption; a hypothesis is always based on an assumption.
2- F ( this states to share the results with other classmates).
3- D (this is a description of an experiment you could conduct; you test a hypothesis (usually) by conducting an experiment.
4- A (this is something you could observe during the experiment, therefore it is an observation).
5- E (this sentence is a conclusion).
6- B (This is an actual question)
The obvious answer is a bc it does not use and toxic fuels
Answer:
we know that acceleration = force / mass
we have force = 100 N
mass = 25 kg
acceleration = 100/25
= 4m/s^2 is the answer
hope it's helpful
1. Red: even without knowing much, just by realizing that red is one of the extremes (think rainbow), we can assume that it is the longest. Also, infrared waves' wavelengths are longer than that of visible light.
2. Electromagnetic radiation: the fact that they have "ray" in the names shows that they are radiation. It's not ultraviolet because that is part of electromagnetic radiation.
3. Photon
