+X axis is passing through from +75 to +48. then to _83
Now force on +75 due to +48 is being repulsive, with the direction -X, So the X component of force is negative.
Force on +75 due to -85 is attractive, with the direction of +X.
∴ The X component of force is positive
K is always constant and positive.
Answer:
i think its 1.5 m/s to the right?
Explanation:
<span>The answer 0.00140 kiloliters
</span><span>ecause one litre=100 centiliters, and one kilolitre=one litre which means that one kilolitre =100000 centiliters So 140 centiliters are 140 divided by 100000 kiloliters=0.00140 kiloliters</span>
The total amount of water on earth <u>remains the same</u>.
<u>Option: A</u>
<u>Explanation:</u>
The quantity of water on Earth remains the same now as it was in the Olden days. All water which is consumed by living things continue to be as part of the Earth's total water content.
The total amount is not exactly constant, as there are two fluxes of water between Earth and the rest of the solar system. There is a steady rain of water-bearing meteoroids hitting the planet, which slowly increases the amount of water. At the same time, molecules of water often dissociate in the upper atmosphere into hydrogen and oxygen due to ultraviolet light from the sun. Some of the hydrogen atoms have enough energy to escape from Earth’s gravitational field, and so are lost. This slowly decreases the amount of water.
In addition, tectonic plate subduction is constantly carrying water down into Earth’s mantle, and volcanoes are constantly spewing water out onto the surface again. The balance between the two processes can change considerably over time.
But all of these actions are meager compared to the total quantity of water on our planet, and two of them are in the opposite direction of the other two. So the overall change is insignificant, even when considered over long spans of geologic time.
Answer:
The work done by Joel is greater than the work done by Jerry.
Explanation:
Let suppose that forces are parallel or antiparallel to the direction of motion. Given that Joel and Jerry exert constant forces on the object, the definition of work can be simplified as:
Where:
- Work, measured in joules.
- Force exerted on the object, measured in newtons.
- Travelled distance by the object, measured in meters.
During the first 10 minutes, the net work exerted on the object is zero. That is:
In exchange, the net work in the next 5 minutes is the work done by Joel on the object:
Hence, the work done by Joel is greater than the work done by Jerry.
