By using
We know that
Using the formula
Answer:
Yo, you just kind of answered it yourself. The Electron Cloud Model is the informal way of describing an atomic orbital.
Explanation:
The analogy of the cloud of electrons is really describing the groups of electrons orbiting around said atom. Depending on the atom, there will be many or few electrons orbiting around it on all sides which can resemble an all-encompassing cloud.
Answer:
10 km/hr/s
Explanation:
The acceleration of an object is given by
where
v is the final velocity
u is the initial velocity
t is the time
For the car in this problem:
u = 0
t = 6 s
Substituting in the equation,
Answer:
a)
b)
c) t = 2.031s X = 1.52m
Explanation:
Let X1 be position of car A as a function of time and X2 be the position of car B as a function of time:
X1 = Xo1 + V1*t If we evaluate this expression at t=t1
S1 = Xo1 + V1*t1 Solving for Xo1 we get its initial position at t=0:
Xo1 = S1 - V1*t1
Similarly for car B:
Xo2 = S2 - V2*t2
Now, to find the instant when car B overtakes car A:
X1 = X2 Replacing their functions in time:
(S1 - V1*t1) + V1*t = (S2 - V2*t2) + V2*t Solving for t:
This is the instant when B reaches A
If we replace this expression in either X1 or X2 expression, we get that position: X1 = X2
If we evaluate these two expressions with the given values:
t = 2.031s and X = 1.52m
