Answer:
Below
Explanation:
To calculate the time it took for the cyclist to finish their race, you can you this equation :
time = displacement / velocity
Plug in your values....
time = (100 mi) / (22 mi/h)
= 4.54545454.... hours
As for sig figs in this question you would need to round this answer to 1 sig fig because 100 only has 1 sig fig. (you round to the lowest # of sig figs in the question)
= 5 hours
It took the cyclist 5 hours to complete their race
Hope this helps! Best of luck <3
D. All of the above.
These are all places you could get information from, therefore making them all sources.
Answer:
A) radiation.
Explanation:
Hello,
In this case, heat transfer from a body with a high temperature to a body with a lower temperature may occur when the bodies are not in direct physical contact with each other or when they are separated in space and it is is called heat radiation. Solids, liquids, or gaseous substances are able to emit energy via a process of electromagnetic radiation because of vibrational and rotational movement of their molecules and atoms.
Hence, since the camp fire is not in contact with the marshmallow and it still cooks it, we can infer that the mechanism of heat transfer is A) radiation. Moreover, both conduction and convection occur when the bodies are in contact.

Newton's first law of motion is connected with inertia :)
