Answer:
The average speed would be 279.167 meters per second.
Explanation:
Speed is the magnitude that expresses the variation in position of an object and as a function of time. In other words, speed is defined as the relationship established between the distance traveled and the time elapsed in the movement of a mobile.
Speed can be calculated using the following expression:
In this case:
- distance= 7,035 km
- time= 7 hours
Since the required unit of speed is meter per second, then you convert from km to meters for the case of distance, and from hours to seconds for the case of time. So:
- distance= 7,035 km= 7,035,000 m (being 1 km= 1,000 m)
- time= 7 hours= 420 minutes= 25,200 seconds (being 1 hour=60 minutes and 1 minute=60 seconds)
Replacing in the definition of speed:
Solving:
Then, <u><em>the average speed would be 279.167 meters per second.</em></u>
Answer:
The two chairs and those sitting on them will move in nearly opposite directions at almost the same speed (assuming that the wheels can only move into two directions - front or back and assuming that the weight of both people are almost the same)
Explanation:
Newton's Third Law states that If an object X exerts a force on object Y, then object Y must exert a force of equal magnitude and opposite direction back on object X.
In other words, when force is applied from source A at B and in direction of B, B also simultaneously returns the force on B and in the direction of B.
This law applies when we jump off the ground when a rocket takes off from the earth into space, etc.
While standing, the body pushes on the earth with a force equal to its own weight. If the ground underneath the body does not meet that force in an equal and opposite direction, both standing on the earth will fall into the earth, with the earth caving underneath it.
You can see why it is important to have a strong foundation for a building and why the depth and strength of the foundation will depend on how much weight is going on it.

1.) Ohm's law is understood as I = V/R. Given that resistance is constant, then voltage changes directly proportional to current.
2.) The more current that passes through a lightbulb, the brighter it glows. The higher the current, the higher the power, where power determines the brightness of a bulb.
3.) A bulb has a specific limit to how much power (Watts) it can handle. Going over the limit would cause the bulb to burn out.
4.) When a bulb burns out, no current will be able to pass through the filament.
<h3><u>Answer;</u></h3>
Sedimentary rock
Granite is uplifted by the movement of tectonic plates. It will most likely become a <em><u>sedimentary rock</u></em>.
<h3><u>Explanation</u>;</h3>
- Granite is an intrusive igneous rock that is coarse-grained and light-colored, mainly composed of feldspar and quartz. It forms from the crystallization or the cooling of magma in the Earth's crust.
- <em><u>When igneous rocks such as granite undergo weathering and erosion they form sediments that are deposited, then compacted and cemented by the movement of tectonic plates resulting to the formation of sedimentary rocks.</u></em>
Answer:
m
Explanation:
1 second = 1000 millisecond, so if within 1 second a bit could travel a distance of 
m through a copper wire then within a millisecond (a thousandth of a second) it should be able to travel through a distance of
m
