Answer:
<h3>The answer is 1.92 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 2.5 g
Volume = 1.3 cm³
We have
We have the final answer as
<h3>1.92 g/cm³</h3>
Hope this helps you
Answer:
About 3m/s
Explanation:
If Julie ran eight quarter mile laps, then she ran a total of 1/4 * 8=2 miles. 2 miles is about 3220 meters, and 18 minutes is 1080 seconds, meaning that her average velocity was about 3m/s. Hope this helps!

Answer:
The magnetic force on the wire at the moment is 2 micro-Newton/(Ampere-meter)
Explanation:
Formula for magnetic force is F = qvB*sin(theeta)
and B = μ*I / 2*pi*r
where
q = charge in coulomb
v = velocity
B = magnetic field strength
μ = permeability of free space
I = current
so from here we get B = (4*pi*10^(-7))(5) / 2*pi*0.01 = 0.0001-T
now ,
F = (2mC)*(10)*0.0001*sin(90)
F = 2 micro-Newton/(Ampere-meter)
