Answer: 58.8235 km/h
speed = distance/time
the distance is 10 km
the time is 10 minutes
the unit is not correct, so we first change minute to hour
so 10/60 is 0.166667, rounded to 0.17.
10 km/ 0.17 hours =
Answer:
1.Divergent boundaries (crust moves apart, magma fills in) Convergent boundaries (magma fills when one plate goes beneath another) Hot spots (a large magma plume rises from mantle)
2.Some mountains are made of solid rock, like the Rocky Mountains or the Swiss Alps. But, some mountains are actually volcanoes.
3.an area under the rocky outer layer of Earth, called the crust, where magma is hotter than surrounding magma.
4.hydrogen sulfide, carbon monoxide, hydrogen chloride, hydrogen fluoride, and other minor gas species.
5.Extinct volcanoes are not expected to erupt in the future. Inside an active volcano is a chamber in which molten rock, called magma, collects. Pressure builds up inside the magma chamber, causing the magma to move through channels in the rock and escape onto the planet's surface.

Answer:
![2.4\times 10^{-5} N](https://tex.z-dn.net/?f=2.4%5Ctimes%2010%5E%7B-5%7D%20N)
Explanation:
We are given that
![I_1=I_2=2.0 A](https://tex.z-dn.net/?f=I_1%3DI_2%3D2.0%20A)
Distance between the wires,![d=5.0 mm=5\times 10^{-3} m](https://tex.z-dn.net/?f=d%3D5.0%20mm%3D5%5Ctimes%2010%5E%7B-3%7D%20m)
1mm=![10^{-3} m](https://tex.z-dn.net/?f=10%5E%7B-3%7D%20m)
Length of other wire,l=0.3 m
Length of one wire is infinite.
We have to find the magnitude of force between the two wires.
We know that magnetic force
![F=\frac{2\mu_0 I_1I_2 l}{4\pi d}](https://tex.z-dn.net/?f=F%3D%5Cfrac%7B2%5Cmu_0%20I_1I_2%20l%7D%7B4%5Cpi%20d%7D)
Where ![\frac{\mu_0}{4\pi}=10^{-7}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cmu_0%7D%7B4%5Cpi%7D%3D10%5E%7B-7%7D)
![F=\frac{2\times 10^{-7}\times 2\times 2\times 0.3}{5\times 10^{-3}}](https://tex.z-dn.net/?f=F%3D%5Cfrac%7B2%5Ctimes%2010%5E%7B-7%7D%5Ctimes%202%5Ctimes%202%5Ctimes%200.3%7D%7B5%5Ctimes%2010%5E%7B-3%7D%7D)
![F=2.4\times 10^{-5} N](https://tex.z-dn.net/?f=F%3D2.4%5Ctimes%2010%5E%7B-5%7D%20N)
When the wires carrying equal current in opposite direction then the force between two wires repel to each other.
Answer:
Total electric potential, ![V=1.32\times 10^6\ volts](https://tex.z-dn.net/?f=V%3D1.32%5Ctimes%2010%5E6%5C%20volts)
Explanation:
It is given that,
First charge, ![q_1=3\ \mu C=3\times 10^{-6}\ C](https://tex.z-dn.net/?f=q_1%3D3%5C%20%5Cmu%20C%3D3%5Ctimes%2010%5E%7B-6%7D%5C%20C)
Second charge, ![q_2=-2.28\ \mu C=-2.28\times 10^{-6}\ C](https://tex.z-dn.net/?f=q_2%3D-2.28%5C%20%5Cmu%20C%3D-2.28%5Ctimes%2010%5E%7B-6%7D%5C%20C)
Distance of first charge from origin, ![r_1=1.15\ cm=0.0115\ m](https://tex.z-dn.net/?f=r_1%3D1.15%5C%20cm%3D0.0115%5C%20m)
Distance of second charge from origin, ![r_2=2\ cm=0.02\ m](https://tex.z-dn.net/?f=r_2%3D2%5C%20cm%3D0.02%5C%20m)
We need to find the total electric potential at the origin. The electric potential at the origin is given by :
![V=\dfrac{kq_1}{r_1}+\dfrac{kq_2}{r_2}](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7Bkq_1%7D%7Br_1%7D%2B%5Cdfrac%7Bkq_2%7D%7Br_2%7D)
![V=k(\dfrac{q_1}{r_1}+\dfrac{q_2}{r_2})](https://tex.z-dn.net/?f=V%3Dk%28%5Cdfrac%7Bq_1%7D%7Br_1%7D%2B%5Cdfrac%7Bq_2%7D%7Br_2%7D%29)
![V=9\times 10^9(\dfrac{3\times 10^{-6}}{0.0115}+\dfrac{-2.28\times 10^{-6}}{0.02})](https://tex.z-dn.net/?f=V%3D9%5Ctimes%2010%5E9%28%5Cdfrac%7B3%5Ctimes%2010%5E%7B-6%7D%7D%7B0.0115%7D%2B%5Cdfrac%7B-2.28%5Ctimes%2010%5E%7B-6%7D%7D%7B0.02%7D%29)
V = 1321826.08 V
or
![V=1.32\times 10^6\ volts](https://tex.z-dn.net/?f=V%3D1.32%5Ctimes%2010%5E6%5C%20volts)
So, the total electric potential at the origin is
. Hence, this is the required solution.
