When ionic compounds melt, do their state change or they are chemically changed? Or both? Since the electrostatic forces are overcame?

When a stone is place on TOP of a very tall mountain, does the gravitational force acting on it decreases? And if a stone is on the ground at sea level, is the gravitational force acting on the stone the highest? If you drop the rock from an airplane, is the gravitational force acting on it the...

What is theory of relativity and how is it related to gravitational time dilation? If a person travels to somewhere in space where 1 hour there is 10 years on Earth and Comes back, will he be of the same age? Or it will just be an hour?

If a constant force acts on an object, does the acceleration changes or velocity changes?

Molar mass is the mass of one mole of atoms of the element . Relative mass is average mass of one atom of that element compared to 1/12 of mass of one carbon-12 atom I don't understand how they are equal. Can someone explain to me please?

I used Colour markers to write on a piece of paper and pasted the piece of paper on the wall. After a few weeks, I noticed the ink faded, or rather, became very faint that the words were almost illegible. Can anyone explain to me this phenomenon scientifically? Thanks

An object with no resultant force can still be moving at constant velocity. Why? Is it because of its kinetic energy or has it got nothing to do with energy?

The Newton's third law states that the force exerted by body A on body B is equal to the force exerted by Body B on Body A . In this case, isn't the object supposed to be stationary because equal forces are acting on both sides? Can someone please explain to me . Thanks

For visualisation's sake, is it something like that? The space between the two intersection in the graph is equivalent to the space between he two lines on the number line?

Can someone explain to be in detail what is quadratic inequality? It's rather confusing. Thank you

Can someone explain to me what are real roots?

Does plasma transport oxygen?

Why do phloem and xylem not contain starch?

Take this question as an example They asked for the current flowing through the bulb and the answer is 6A I know that it's 12V divided by 2 ohms(2 ohm is the resistance of resistor X) , but why? I thought the current is supposed to be 12V divided by the resistance of bulb and resistor X(total...

or is it beacuse its kwh which means kw x h and not kw/h?
