6.25 gram of element x would be left after 4 years.
<h3>What's half life of an element?</h3>
- Half - life is the time period of decay of an element to half of its initial number of nuclei.
- After n no. of half lives, no. of nuclei left in the sample is initial number of nuclei / 2^n
<h3>What's the amount of 100 gm of element x left after 4 half lives ?</h3>
Leftover amount of the element x = 100/2^4
= 100/16 = 6.25 gram
Thus, we can conclude that 6.25 gram of element x would be left after 4 years.

Answer:
gets higher
Explanation:
There are videos that show the range of human hearing. If you would play the video, you would notice that if the frequency increases, the pitch would also increase.
Complete Question
A proton is located at <3 x 10^{-10}, -5*10^{-10} , -5*10^{-10}> m. What is r, the vector from the origin to the location of the proton
Answer:
The vector position is
Explanation:
From the question we are told that
The position of the proton is
Generally the vector location of the proton is mathematically represented as
So substituting values
Answer:
P = 6*5 = 30 [kg*m/s]
Explanation:
in order to solve this problem, we must remember that linear momentum is defined as the product of mass by Velocity. This way you can calculate the momentum using the following equation.
P = m*v
where:
P = lineal momentum [kg*m/s]
m = mass = 6 [kg]
v = velocity = 5 [m/s]
P = m*v
P = 6*5 = 30 [kg*m/s]
