Potential difference across the entire cd player is 12 V
Answer:
L^2T^-1
Explanation:
a = vr
The dimension of v is LT^-1
The dimension of r is L
Therefore, the dimension of a = LT^-1 × L = L^2T^-1
The rate of solution is the rate at which a substance dissolves.
the factors on which the rate of solution depends are :
particles area of the solute: greater the area , greater is the rate of solution.
stirring: stirring increases the rate of solution.
temperature: increasing temperature increases the rate of solution.
hence the correct choice is
d) how fast a substance dissolves
The capacitor is used to store electric charge.That is what makes capacitors special. <span>
The charge that flows into the capacitor is stored on the plate of the capacitor that the source voltage is connected to. </span>When current flows into a capacitor, the charges get “stuck” on the plates because they can’t get past the insulating dielectric. One plate is positively charged and the other negatively <span>The stationary charges on these plates create an </span>electric field. <span>When charges group together on a capacitor like this, the cap is storing electric energy just as a battery might store chemical energy.</span>
<span>the first one ( usually consists of fine sand, silt, and clay particles )
Hope im right!(: </span>
