They are called Ions
Definition is this: atom of molecule with a net electric charge caused by the loss or gain of one or more electrons.
Hope this helps! :D
<span>Weight of block, Wb = mass*gravity = 50*9.8 = 490 N</span>
Since block is being pulled up by a 13-degree slope
Therefore, Force which is acting parallel to the slop:
<span> F p =490 Sin </span>
= 110.2N
Force which is acting perpendicular to the slope:
<span> Fv =490 Cos</span>
= 477.4 N
Net force can be given as follows:
<span>F n = (250 - 110.2 - 0.2*</span>477.4) N
<span>Fn=44.3N</span>
Now acceleration is given by the ratio of force to mass
<span>a = Fn/m</span>
<span>=44.3/50 = 0.89 ms^<span>-2</span></span>
The size of the field 'decreases'. Imagine zooming in on your TV so that your face is pressed up against the screen. you can see the individual pixels but you cannot see the whole picture because the sizer of your 'field of view' has shrunk.
Answer: 1 000 times
Explanation: 1 000 centimetre is equal to 1 dekacemetre.
Using conversion will apply in converting every number.
It takes 365 days to orbit the sun...hence why our years are so long
