D.Atoms can be divided into smaller parts.
Dalton's atomic theory was the first complete attempt to describe allmatter in terms of atoms and their properties. Dalton based his theory on the law of conservation of mass and the law of constant composition. The first part of his theory states that allmatter is made of atoms, which are indivisible.
Answer:
Speed of the soccer ball with respect to ground is ZERO
Explanation:
As we know that truck is moving with speed 20 mph
Now a soccer ball is shoot from truck with respect to the motion of truck in opposite direction
The relative speed of the soccer ball is
now we know that
so we have
so we have
The amount of a radioactive element over time can be written as:
So, considering that we know the time of its half life, we know how long it takes to get to half the original amount. This is (usint the amount of days in microseconds):
Thus, lambda=3.82*10^(-11)/microseconds
We are talking about some periodic phenomenon. so, period is the amount of time T it takes to repeat itself, and frequency is the number of times f it repeats in one time.
