Lithium metals reacts slowly with water to form a colourless solution of lithiums hydroxide (LiOH) and hydrogen gas (H2). The resulting solution is basic because of the dissolved hydroxide. The reaction is exothermic, but the reaction is slower than that of sodium (immediately below lithium in the periodic table)
Motaion would be it have a good day
Impulse=force x time
force=mass x acceleration due to gravity
force=
impulse =3000 x 2.5= ( sorry i don't have a calculator right now so you must calculate this yourself)
I converted from kg to g because it is the standard.
Hope this helps you.
Answer:
585lb
Explanation:
Given the following
F1 = 235lb
F2 = 350lb
The resultant is expressed as;
FR = F1+F2
Substitute the given values
FR = 235+350
FR = 585lb
Hence the magnitude of the resultant is 585lb
Explanation:
Potential energy is the energy obtained by an object due to the position of an object. Whereas kinetic energy is the energy obtained by an object due to its motion.
For example, an ball is placed over a building of height h. Then steps followed to covert its potential energy into kinetic energy are as follows.
Step 1: When ball is at placed over a building of height h, then it has only potential energy and no kinetic energy.
Step 2: A man pushes the ball and it moves in the downward direction.
Step 3: When ball starts to move or fall it gains kinetic energy, that is potential energy now becomes equal to 0.
Similarly, on reaching the ground and after bouncing a few times when it stop moving then kinetic energy converts into potential energy.
