Answer: D-variable

Explanation:

A variable is the parameter over which changes can be made and observed so as to determine the outcome of the experiment. The two important variables such as dependent and independent variables and changes occurring over them can be useful in determining the outcome of the experiment.

An independent variable is the one which can be changed or manipulated by the experimenter so as to observe the impact of such change over the dependent variable. A dependent variable cannot be manipulated in the experiment instead the changes occurring in the dependent variable are because of the changes occurring in the independent variable. The observations on the dependent variable can be used for determining the outcome of the experiment.

The first law of thermodynamics can be given as ________.
MrRa [10]
The first law of thermodynamics can be written as
\Delta U = Q-W
where
\Delta U is the variation of internal energy of the system
Q is the amount of heat absorbed by the system
W is the work done by the system on the surrounding.

Using this form, the sign convention for Q and W becomes:
Q > 0 --> heat absorbed by the system (because it increases the internal energy)
Q < 0 --> heat released by the system (because it decreases the internal energy)
W > 0 --> work done by the system (for instance, an expansion: when the system expands, it does work on the surrounding, and so the internal energy decreases, this is why there is a negative sign in the formula Q-W)
W < 0 --> work done by the surrounding on the system (for instance, a compression: when the system is compressed, the surrounding is doing work on the system, and so the internal energy of the system increases)

Does a black hole have 2 sides that pull light together?
Ostrovityanka [42]
Check this Light doesn't have mass or gravity right?
So if it doesn't have mass or gravity so light can only affect objects with mass
Does that make sense?
The black hole has gravity and remember light doesn't have gravity so does it affect the light?
To answer that yes, and since light doesn't have gravity it gets "pulled" into the black hole
