Answer:
1 minute 36.85 seconds
Explanation:
First we need to convert the miles into meters, as the demanded result should be in meters.
1 mile = 1,609.34 meters
Also, 6.5 minutes should be converted into seconds.
1 minute = 60 seconds
6.5 x 60 = 390 seconds
Now we need to divide the miles with the seconds to see how much meters have been run in a second.
1,609.34 / 390 = 4.13 meters
The suggested meters now should be divided with the distance run in one second.
400 / 4.13 = 96.85 seconds
So we get a result of 96.85 seconds, or 1 minute 36.85 seconds.

i am pretty sure you are correct and so sorry if i am wrong i am just trying to help no need to give me anything if i am right but it might be the one abouve the one you chose :) please let me know if i am wrong or right
Explanation:
Cell are small and us human can't see them with our own eyes. it is in possible to see cell without a microscope
Answer: v = 
Explanation: q = magnitude of electronic charge = 
mass of an electronic charge =
V= potential difference = 4V
v = velocity of electron
by using the work- energy theorem which states that the kinetic energy of the the electron must equal the work done use in accelerating the electron.
kinetic energy =
, potential energy = qV
hence, 

Answer:
The kinetic energy is 
Explanation:
From the question we are told that
The radius of the orbit is 
The gravitational force is 
The kinetic energy of the satellite is mathematically represented as

where v is the speed of the satellite which is mathematically represented as

=> 
substituting this into the equation

Now the gravitational force of the planet is mathematically represented as

Where M is the mass of the planet and m is the mass of the satellite
Now looking at the formula for KE we see that we can represent it as
![KE = \frac{ 1}{2} *[\frac{GMm}{r^2}] * r](https://tex.z-dn.net/?f=KE%20%20%3D%20%20%5Cfrac%7B%201%7D%7B2%7D%20%2A%5B%5Cfrac%7BGMm%7D%7Br%5E2%7D%5D%20%2A%20r)
=> 
substituting values
