How would you do (k-3)/4 = 10 ?

givi [52]

Are you asking how to solve for k? In that case, multiply both sides by 4. Then add 3 to both sides:

(k-3) = 40
k = 43

What is the repulsive force between two pith balls that are 13.0 cm apart and have equal charges of −24.0 nC?

daser333 [38]

Answer:

The repulsive force is $3.067\times10^{-4}N$ .

Step-by-step explanation:

Consider the provided information.

The coulomb's law to calculate the repulsive force: $F=\frac{kQ_1Q_2}{r^2}$

Where the value of k is 9.00×10⁹ Nm²/C²

Substitute the respective values in the above formula.

$F=\frac{9\times10^9\frac{N\cdot m^2}{c^2} \times(-24\times10^{-9}C)^2}{[(13 cm)(\frac{1m}{100cm} )]^2}$

$F=\frac{9\times10^9\frac{N\cdot m^2}{c^2} \times(-24\times10^{-9}C)^2}{(0.13 m)^2}$

$F\approx0.0003067N$

$F=3.067\times10^{-4}N$

Hence, the repulsive force is $3.067\times10^{-4}N$ .

Usan has a collection of 105 nickels and dimes. If the number of nickels is six times the number of dimes, how many nickels and

skad [1K]

Answer:

90 nickels and 15 dimes

Step-by-step explanation:

If one is six times the other, then you would have 7 equal piles. Divide 105 by 7 to get 15 which is the number in each pile(number of dimes). Then 105 minus 15 gives you the total of the rest of the piles(number of nickels).

Check:

90 plus 15 equals 105, and

15 times 6 equals 90.
