When the elevator is going up (assuming the elevator is acceleration)

When the elevator is accelerating downwards, the total gravitational force would be larger.

If the elevator is accelerating upwards, then the gravitation force would be smaller, thus the tension in the string would be smaller.

Explain why cooler stars are red and hotter stars are blue
sergey [27]
More cool stars produce much of their light in the red part of the spectrum, so you see them, and bam, the color red. More hot stars, however, produce much more of their light in the green and or yellow spectrums, with much more tinier amounts of red / blue. This balance of the colors, your eye, sees simply as white. The more hot something is, the greater frequency of radiation it produces! Blue light has a higher frequency than red light, so the stars that glow red are cooler, than the stars that glow blue. :)

Hope this helped!

When the distance between two objects doubles, what happens to the gravitational attraction between these two objects?
Feliz [49]

Answer:

As indicated by Newton's law of attraction each article or body in the universe draws in every single item towards one another and that power of fascination is straightforwardly relative to the result of their masses and contrarily corresponding to the square of the distance between them.  

The power of gravity between two articles will diminish as the distance between them increments. The two most significant elements influencing the gravitational power between two items are their mass and the distance between their focuses. As mass increments, so does the power of gravity, however an increment in distance mirrors a reverse proportionality, which makes that power decline dramatically.  

At that point by Newton's All inclusive Law of Attractive energy;  

F=GMm/R^2  

Mm= result of the majority  

R=Distance Between the two masses by focus.  

On the off chance that R is multiplied, new force=GMm/(2R)^2  

=GMm/4R^2  

Unique Power/New Force=4/1  

F/4=New Power

A water tank has a mass of 3.64 kg when empty and 51.8 kg when filled to a certain level. What is the mass of the water in the t
mrs_skeptik [129]
Subtract the total mass of the tank and water by the mass of the empty tank. That will yield the mass of the water. 

51.8 - 3.64 = 48.16.

Your answer is 48.16 kg
