Explanation:
v=frequency multiply by lambda
I think the answer is just Option C, cause Alpha radiation has an atomic mass unit (amu) of 4, since alpha radiation is just a helium nucleus.
Answer:
yes, 800 has 1 significant digit
neither leading zero nor trelling zero are significant figure except when there's a decimal point
Answer:
f = 1 / [ 2*pi*R*C*Sqrt(2*N)
Explanation:
f = 1 / [ 2*pi*R*C*Sqrt(2*N) is the formula. Sorry I answered in English.
The particle has constant acceleration according to

Its velocity at time
is



Then the particle has position at time
according to


At at the point (3, 6, 9), i.e. when
, it has speed 8, so that

We know that at some time
, the particle is at the point (5, 2, 7), which tells us

and in particular we see that

and

Then



That is, there are two possible initial velocities for which the particle can travel between (3, 6, 9) and (5, 2, 7) with the given acceleration vector and given that it starts with a speed of 8. Then there are two possible solutions for its position vector; one of them is
