Answer:1200 kg
Explanation:
Given
Electromagnet can lift a mass of 
Magnetic force necessary to hold mass is proportional to Magnetic field
and magnetic field (B) is proportional to NIA
where N=no of turns
I=current in the magnet
A=area of cross-section
When we double the no of turns and triple the current then
N becomes 2 N
I becomes 3 I
therefore magnetic field becomes 6 times
Thus magnetic force becomes 6 times and we can say that electromagnet can hold the 6 times of given weight
i.e. 
The wave propagates outward horizontally across the surface of the pond. As you can see from the ripples, the water molecules move up and down, <em>perpendicular to the horizontal movement of the wavefronts</em>.
By definition this is a transverse wave.
Answer:
Heat has accelerated water atoms enough to break the surface tension which leads the liquid to turn into a gas
Explanation:
The state of a substance depends on the distribution of its atoms, therefore any atmosphere change (in this case heat) enough to change the atoms Distribution results in a change of state.
brainliest please ;)
