Answer:

Explanation:

The significant figures are defined as the figures that give the value and information of the accuracy of a measurement. The zero is the number that can have two behaviors if it is to the right of us numbers is significant since it gives an idea of ​​the precision of the meditation, but if it is on the left and only serves to indicate the position of the decimal point it is not significant ; All of us numbers are always significant.

 Using the above statements we will shrink the significant numbers numbers:

number  Significant     description

                figure

25.030        5                  all significant, zero right indicates measurement accuracy

0.006070    4                 zeros to the left of the “6” indicate position of the decimal point, they are not significant

1,004            4                 all significant

1.300520     7                 all significant, zero right indicates accuracy is significant

25.030: 5 because zeroes are after decimal

0.006: 3 because 2 zeroes are after decimal

1.004: 4 because zeroes are between numbers

(Not sure what you meant to write for these)

1.300520: 7

1.3005: 5 because zeroes are after decimal and between numbers

20: 1 because zero isn't after a decimal or between numbers

Numbers other than 0 are always SigFigs!

Hope I helped! :)

How will a current change if the resistance of a circuit remains constant while the voltage across the circuit decreases to half
beks73 [17]

Answer:

1. The current will drop to half of its original value.

Explanation:

The problem can be solved by using Ohm's law:

V=RI

where

V is the voltage across the circuit

R is the resistance of the circuit

I is the current

We can rewrite it as

I=\frac{V}{R}

In this problem, we have:

- the resistance of the circuit remains the same: R' = R

- the voltage is decreased to half of its original value: V'=\frac{V}{2}

So, the new current will be

I'=\frac{V'}{R'}=\frac{V/2}{R}=\frac{1}{2}\frac{V}{R}=\frac{I}{2}

so, the current will drop to half of its original value.
