The acceleration goes up.
Answer:
In particle physics, a lepton is an elementary particle of half-integer spin (spin 1⁄2) that does not undergo strong interactions.[1] Two main classes of leptons exist: charged leptons (also known as the electron-like leptons or muons), and neutral leptons (better known as neutrinos). Charged leptons can combine with other particles to form various composite particles such as atoms and positronium, while neutrinos rarely interact with anything, and are consequently rarely observed. The best known of all leptons is the electron.
Answer:
A
Explanation:
Electromagnet: It is a temporary magnet. It consists of wrapping coils around iron core and the power source. When the current passes through the coils around the iron core then it will get magnetized. The domains of the electromagnet gets aligned.
As long as the current passes through it, it will get magnetized. It will loose its magnetism easily when the power is switched off.
In the electromagnet, the strength of the magnetism can be increased or decreased. The poles of the electromagnet are not fixed.

Answer:
12.5 grams
Explanation:
From the question,
E' = E/2⁽ⁿ/a⁾....................... Equation 1
Where E' = mass left, E = Original mass, n = time, a = half-life.
Given: E = 200 grams, n = 40 years, a = 10 years.
Substitute these values into equation 1
E' = 200/2⁽40/10⁾
E' = 200/2⁴
E' = 200/16
E' = 12.5 grams.
Hence 12.5 grams of the isotope will be left.
