Answer:
Explanation:
As we know that electrostatic potential energy of the electron is converting here into kinetic energy
so we will have
so here we know that
so from above equation we have
Answer:
Check below for the explanations required
Explanation:
The following processes/events take place in the cooling of a fluid.
- A reduction in the kinetic energy of the molecules of the fluid
- The molecular speed reduces ( i.e.there will be a reduction in the speed at which the molecules move)
- The cohesive force between the molecules will increase ( i.e the molecules will no longer be drifted apart, they will now move closer to each other
- The temperature of the fluid reduces as it cools down
- There will be an increase in density
Answer:
6957.04N
Explanation:
Using
vf2=vi2+2ad
But vf = 0 .
So convert 50km/hr to m/s, and you need to convert 61 cmto m
(50km/hr)*(1hr/3600s)*(1000m/km) = 13.9m/s
61cm * (1m/100cm) = .61m
So n
0 = (13.9m/s)^2 + 2a(.61m)
a = 158.11m/s^2
So
using F = ma
F = 44kg(158.11m/s^2) = 6957.04N
Answer:
Different elements all have different amounts of electrons in there outter shell.
Explanation
If you look at a periodic table, the elements are all listed in "Groups" up at the top you'll see the numbers, or columns. Each column's number represent how many electrons there are in each particular element.
hope this makes sense....
Answer:
Explanation:
As we know that
also we know that
it is given as
also we can find the magnitude of two vectors as
similarly we have
now we know the formula of dot product as
