Answer:
<h2>135,000 J</h2>
Explanation:
The work done by an object can be found by using the formula
workdone = force × distance
From the question we have
workdone = 900 × 150
We have the final answer as
<h3>135,000 J</h3>
Hope this helps you
Answer:
your answer will be 320kg that would be the pressure at the bottom surface of the block
Answer:
The direction is due south
Explanation:
From the question we are told that
The energy of the electron is ![E = 19.0keV = 19.0 *10^3 eV](https://tex.z-dn.net/?f=E%20%3D%2019.0keV%20%3D%2019.0%20%2A10%5E3%20eV)
The earths magnetic field is ![B = 42.3 \muT = 42.3 *10^{-6} T](https://tex.z-dn.net/?f=B%20%3D%2042.3%20%5CmuT%20%3D%2042.3%20%2A10%5E%7B-6%7D%20T)
Generally the force on the electron is perpendicular to the velocity of the elecrton and the magnetic field and this is mathematically reresented as
![\= F = q (\= v * \=B)](https://tex.z-dn.net/?f=%5C%3D%20F%20%3D%20q%20%28%5C%3D%20v%20%2A%20%5C%3DB%29)
On the first uploaded image is an illustration of the movement of the electron
Looking at the diagram we can see that in terms of direction the magnetic force is
![\= F =q(\=v * \= B)= -( -\r i * - \r k)](https://tex.z-dn.net/?f=%5C%3D%20F%20%20%3Dq%28%5C%3Dv%20%2A%20%5C%3D%20B%29%3D%20-%28%20-%5Cr%20i%20%2A%20-%20%5Cr%20k%29)
![= -(- (\r i * \r k))](https://tex.z-dn.net/?f=%3D%20-%28-%20%28%5Cr%20i%20%2A%20%5Cr%20k%29%29)
generally i cross k = -j
so the equation above becomes
![\= F = -(-(- \r j))](https://tex.z-dn.net/?f=%5C%3D%20F%20%3D%20-%28-%28-%20%5Cr%20j%29%29)
![= - \r j](https://tex.z-dn.net/?f=%3D%20-%20%5Cr%20j)
This show that the direction is towards the south
Answer:
Using clean, renewable, and readily available solar energy as fuel.
Preserving natural resources by not requiring the use of wood or other biomass fuels to cook.
Not producing dangerous emissions which pollute local environments and contribute to climate change.
