Answer:
If you meant 2.34, 2.34 meters = 23.4 decimeters.
Formula: multiply the value in meters by the conversion factor '10'.
So, 2.34 meters = 2.34 × 10 = 23.4 decimeters.
Hope that helps. x
Two in middle, so Newton's 2nd law. Equal and opposite force (both are moving). You have to assume no friction since it's an ice rink.
<span>Skater 1: 45kg 0.66m/s </span>
<span>Skater 2: xkg 0.81ms/ </span>
<span>Since force is equal, 45*0.66=x*0.81 </span>
<span>Solve for x. </span>
<span>So the answer would be 36.7kg</span>

Answer:
0.00264C
Explanation:
Using the Columbs law formula
F = kq1q2/r²
F is the force of attraction
q1 and q2 are the charges
r is the distance between the charges.
k is the Coulomb's cinsrsnty
Given F = 19N, q1 = -0.0005C
r = 25m q2 = ?
Substituting
19 = 9×10^9×-0.0005q2/25²
11875 = -4,500,000q2
q2 = 11,875/-4,500,000
q2 = - 0.0264C
Magnitude of the second charge is 0.00264C
The answer is false. I know for a fact it is but i dont remember which ones.
