Well i once did an expiremnet and it exploaded in my face lol
Explanation:
Answer:
3mol/L or 3mol/dm³
Explanation:
Given:
solution contains 6 moles of solute consider it 'n' i.e 6 moles
Volume of solution consider in 'V' i.e 2 liters
Required:
Molarity of solution 'M'=?
Formula:
In order to find Molarity of a solution, no.of moles of solute divided by Vol.of solution in litres (∴ number of moles in 1 litre of solution)
Molarity = no.of moles of solute/Vol.of solution in litres or dm³
Calculations:
M= 6mol/2L =
M= 3mol/L or 3mol/dm³
Therefore, the molarity of a solution that contains 6 moles of solute in 2 liters of solution is 3mol/L or 3mol/dm³
I think you're fishing for "temporary magnet" or something like that,
but I don't agree with it.
Credit card strips, refrigerator magnets, recording tape, bar magnets,
and big heavy horseshoe magnets are permanent magnets ... you don't
have to keep an electric current circulating around them to make them
magnetic.
But that doesn't mean that they stay magnetic no matter WHAT you do
to them. They can be DEmagnetized by being heated, dropped on the
floor, hit with a hammer, or in the presence of another, stronger magnet.

Answer:
Explanation:
Net torque is calculated by multiplying the force with distance from the point of application of force to the point of pivot .
If more than 2 forces are present, then we either subtract the product of forces with their respective distances from pivot point or we add them . It depends on whether they both are present on opposite sides of pivot or on same side of pivot .
When a force is applied directly to the pivot point of balance, then the torque on due that force = 0 (zero) .
It is so because the torque is defined as the product of force and perpendicular distance from the pivot point but here the distance is 0 , therefore torque is zero.
